RF ENERGY EXPOSURE INFORMATION
2.1
RF ENERGY EXPOSURE AWARENESS, CONTROL INFORMATION,
AND OPERATION INSTRUCTIONS FOR FCC OCCUPATIONAL USE
REQUIREMENTS
Before using your mobile two-way radio, read this important RF energy awareness and control
information and operational instructions to ensure compliance with the FCC’s RF exposure
guidelines.
This radio is intended for use in occupational/controlled conditions, where users have full
knowledge of their exposure and can exercise control over their exposure to meet FCC
limits. This radio device is NOT authorized for general population, consumer, or any
other use.
Changes or modifications not expressly approved by M/A-COM, Inc. could void the user's
authority to operate the equipment.
CAUTION
This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide
communications between two or more users over a distance. It uses RF energy or radio waves to send and
receive calls. RF energy is one form of electromagnetic energy. Other forms include, but are not limited
to, electric power, sunlight, and x-rays. RF energy, however, should not be confused with these other
forms of electromagnetic energy, which, when used improperly, can cause biological damage. Very high
levels of x-rays, for example, can damage tissues and genetic material.
Experts in science, engineering, medicine, health, and industry work with organizations to develop
standards for exposure to RF energy. These standards provide recommended levels of RF exposure for
both workers and the general public. These recommended RF exposure levels include substantial margins
of protection. All two-way radios marketed in North America are designed, manufactured, and tested to
ensure they meet government established RF exposure levels. In addition, manufacturers also recommend
specific operating instructions to users of two-way radios. These instructions are important because they
inform users about RF energy exposure and provide simple procedures on how to control it. Please refer
to the following websites for more information on what RF energy exposure is and how to control your
exposure to assure compliance with established RF exposure limits.

2.1.1
Federal Communications Commission Regulations
Your M/A COM, Inc. M7200 mobile two-way radio is designed and tested to comply with the FCC RF
energy exposure limits for mobile two-way radios before it can be marketed in the United States. When
two-way radios are used as a consequence of employment, the FCC requires users to be fully aware of
and able to control their exposure to meet occupational requirements. Exposure awareness can be
facilitated by the use of a label directing users to specific user awareness information. Your M/A COM,
Inc. M7200 two-way radio has an RF exposure product label. Also, your M7200 Installation and
Operator’s Manuals include information and operating instructions required to control your RF exposure
and to satisfy compliance requirements.
MM-011553-001

OPERATION SAFETY RECOMMENDATIONS
3.1
TRANSMITTER HAZARDS
The operator of any mobile radio should be aware of certain hazards common to
the operation of vehicular radio transmitters. A list of several possible hazards is
given:
•
Explosive Atmospheres – Just as it is dangerous to fuel a vehicle with the motor running, similar
hazards exist when operating a mobile radio. Be sure to turn the radio off while fueling a vehicle. Do
not carry containers of fuel in the trunk of a vehicle if the radio is mounted in the trunk.
Areas with potentially explosive atmosphere are often, but not always, clearly marked. Turn OFF
your radio when in any area with a potentially explosive atmosphere. It is rare, but not impossible that
the radio or its accessories could generate sparks.
3.2
•
Interference to Vehicular Electronics Systems – Electronic fuel injection systems, electronic antiskid braking systems, electronic cruise control systems, etc., are typical electronic systems that can
malfunction due to the lack of protection from radio frequency energy present when transmitting. If
the vehicle contains such equipment, consult the dealer and enlist their aid in determining the
expected performance of electronic circuits when the radio is transmitting.
•
Electric Blasting Caps – To prevent accidental detonation of electric blasting caps, DO NOT use
two-way radios within 1000 feet of blasting operations. Always obey the “Turn off Two-Way
Radios” signs posted where electric blasting caps are being used. (OSHA Standard: 1926-900)
•
Liquefied Petroleum (LP) Gas Powered Vehicles – Mobile radio installations in vehicles powered
by liquefied petroleum gas with the LP gas container in the trunk or other sealed-off space within the
interior of the vehicle must conform to the National Fire Protection Association standard NFPA 58
requiring:
¾ The LP gas container and its fittings.
¾ Outside filling connections shall be used for the LP gas container.
¾ The LP gas container shall be vented to the outside of the vehicle.
SAFE DRIVING RECOMMENDATIONS
(Recommended by AAA)
10
•
Read the literature on the safe operation of the radio.
•
Keep both hands on the steering wheel and the microphone in its hanger whenever the vehicle is in
motion.
•
Place calls only when the vehicle is stopped.
•
When talking from a moving vehicle is unavoidable, drive in the slower lane. Keep conversations
brief.
•
If a conversation requires taking notes or complex thought, stop the vehicle in a safe place and
continue the call.
•
Whenever using a mobile radio, exercise caution.
MM-011553-001
OPERATING RULES AND REGULATIONS
Two-way FM radio systems must be operated in accordance with the rules and regulations of the local,
regional, or national government.
In the United States, the M7200 mobile radio must be operated in accordance with the rules and
regulations of the Federal Communications Commission (FCC). As an operator of two-way radio
equipment, you must be thoroughly familiar with the rules that apply to your particular type of radio
operation. Following these rules helps eliminate confusion, assures the most efficient use of the existing
radio channels, and results in a smoothly functioning radio network.
When using your two-way radio, remember these rules:
•
It is a violation of FCC rules to interrupt any distress or emergency message. As your radio operates
in much the same way as a telephone “party line,” always listen to make sure that the channel is clear
before transmitting. Emergency calls have priority over all other messages. If someone is sending an
emergency message – such as reporting a fire or asking for help in an accident – KEEP OFF THE
AIR!
•
The use of profane or obscene language is prohibited by Federal law.
•
It is against the law to send false call letters or false distress or emergency messages. The FCC
requires that you keep conversations brief and confine them to business. To save time, use coded
messages whenever possible.
•
Using your radio to send personal messages (except in an emergency) is a violation of FCC rules.
You may send only those messages that are essential for the operation of your business.
•
It is against Federal law to repeat or otherwise make known anything you overhear on your radio.
Conversations between others sharing your channel must be regarded as confidential.
•
The FCC requires that you identify yourself at certain specific times by means of your call letters.
Refer to the rules that apply to your particular type of operation for the proper procedure.
•
No changes or adjustments shall be made to the equipment except by an authorized or certified
electronics technician.
Under U.S. law, operation of an unlicensed radio transmitter within the jurisdiction of
the United States may be punishable by a fine of up to $10,000, imprisonment for up to
two (2) years, or both.
4.1
OPERATING TIPS
The following conditions tend to reduce the effective range of two-way radios and should be avoided
whenever possible:
•
Operating the radio in areas of low terrain, or while under power lines or bridges.
•
Obstructions such as mountains and buildings.
•
In areas where transmission or reception is poor, some improvement can be obtained by moving a few
yards in another direction or moving to a higher elevation.

PRODUCT DESCRIPTION
The M7200 Vehicular Tactical Network provides public safety users extended connectivity with the most
advanced digital voice and data network. Extended connectivity is through two tightly coupled digital
radios that function as an in-band router between the public safety network, the mobile vehicle, and the
user's portable radio. Digital voice and data are routed between the network and the user's control head
and mobile data terminal within the vehicle or the user's portable radio when the portable radio cannot
maintain direct network connection.
The M7200 mobile radio is a state-of-the-art radio that operates seamlessly between the 800 MHz
frequency band and the 700 MHz frequency band. The M7200 is designed to meet the critical
communications demands of public service users and complies with MIL-STD-810F specifications.
The M7200 is capable of supporting multiple operating modes, including OpenSky digital operation,
EDACS or ProVoice trunked modes, P25 digital trunked mode, P25 digital conventional mode, and
conventional analog mode.
The M7200 uses Time Division Multiple Access (TDMA) technology in the OpenSky mode to allow
multiple users to share a single RF channel. In addition, a single RF channel can support simultaneous
digital voice and data communications.
The M7200 provides integrated voice and data services. Voice operation is provided using a microphone
and speaker included in the radio installation kit. For data transfers, the M7200 is constructed with an
industry-standard RS-232 interface serial port for connecting an optional laptop PC.
A PC, not included with the M7200, provides network connectivity through the standard serial
(DCE-type) interface.
The M7200 has an integrated Global Positioning System (GPS) receiver. This allows the M7200 to fully
support the Automatic Vehicular Locator (AVL) for fleet management and dispatch applications.
The OpenSky M7200 benefits from a flexible, software-based digital radio design. Features and user
profiles are software-defined and can be reprogrammed over the air. The optional over-the-air
programming feature allows communication protocols to be changed easily and added at any time.
5.1
REMOTE CONTROL HEAD OPERATION
For remote mount installations configured with a CH721 control head, all normal radio operations and
interfaces can be handled via the control head connected to the radio unit by a single twisted-pair
connection routed through a vehicle. Up to six control units may be attached to a trunk mount radio. Each
control head provides a serial access point for data and any one (only one at a time) can be connected to a
data device such as a personal computer.
Where multiple control heads are connected or where a dash-mount radio is installed with additional
remote control heads, the following features are available from each position:
12
•
Outgoing voice calls can be initiated. (Any control head can initiate a call but only one can talk at a
time. All other connected control heads will hear both sides of the conversation.)
•
Incoming and outgoing audio can be heard. (Outgoing audio is not broadcast at the source position.)
•
Independent audio control is available.
•
Radio settings such as talk group, scan mode etc., can be controlled. (Any connected control head can
override the radio settings of other connected control heads.)
•
Comfort settings, such as volume and display brightness that are applicable to the individual control
head can be adjusted and cannot be overridden by other control heads.
MM-011553-001
•
5.2
An optional intercom function is available between control units. (Audio will be broadcast to ALL
connected control heads.)
INTERCOM OPERATION
The intercom option, a licensed option, allows the M7200 radio to pass audio locally between control
heads and not over the network. It gives users at multiple control heads connected to the same radio the
ability communicate with each other without transmitting over-the-air. When activated, incoming network
radio calls are still scanned and broadcast at each control head.
5.3
V-TAC OPERATION
V-TAC operation requires the V-TAC hardware configuration (RF Combiner, Vehicular Repeater Base
VRB, and Mobile Radio Unit MRU) and offers the user 4 different operating modes: Extended Coverage
for individual users (XCOV), Extended Coverage for talk groups (XCOV-TG), Scene of Incident (SOI),
and normal Mobile-Only operation. Refer to Section 6.34 for operating information on these modes.

The front panel of the control head includes a dot matrix display, controls for menu navigation, an
emergency button, three pre-set buttons, a power button/rotary volume dial, and a microphone connector.
In addition, the system model control head features a DTMF keypad. Table 6-1 lists all default front panel
controls and their functions.
Figure 6-1: System Model
Figure 6-2: Scan Model
The buttons on the front panel are backlit for operation in a low ambient light level such as nighttime
operation. Some buttons also flash to provide feedback of various operating conditions.

MM-011553-001
In addition, the front panel contains a light-level sensor that samples ambient light levels for automatic
display and button backlight brightness adjustments. In other words, it automatically brightens the display
and backlights when higher external light levels exist and it automatically dims the display and backlights
during lower external light levels.
Button function may vary depending upon system programming, radio hardware, and
optional configurations. Complete the table in APPENDIX A if the keys have been
remapped to provide new functions.

POWER UP AND VOLUME CONTROL
6.2.1
Power Up
1. Rotate the Power/Volume Control knob clockwise to power on the radio. The display will illuminate
when the radio powers up.
2. Wait for the power-up sequence to complete, which takes approximately ten (10) seconds.
During this time, if enabled for auto registration, the radio is provisioned with a customized user
personality designed for the user’s specific needs by the OpenSky network administrator.
If this personality contains encrypted talk groups or if the user is authorized for, and intends to use,
manual encryption, User Login must be performed. This requires a system model control head so that
the User ID and password can be entered.
3. When provisioning is complete, the radio will display the Dwell Display.
If User Login is required, the bottom line of the Dwell Display will flash the message “Pls Login.”
6.2.2
Volume Control
Turn the Power/Volume Control knob clockwise to increase the volume and counter-clockwise to
decrease the volume.
6.3
SELF-TEST
After power-up, the M7200 radio undergoes a multi-function automatic registration procedure. As many
as sixteen (16) possible radio profiles are downloaded to the radio from the network in response to the
User’s ID.
6.4
LOGIN TO THE NETWORK
Login occurs either automatically (auto registration) if the radio has a valid registration or, if enabled and
authorized for encryption (Section 6.30), requires the user to enter a User ID and password.
If encryption is enabled and authorized on the radio, the user will be prompted to “Pls Login” with the *1
login command, a User ID, and password [System Model Control Head required].
1. Press *1 (Login command).
2. Enter the full 10-digit User ID.
3. Press the # key.
4. Enter the password. See the following NOTE.
•
If the radio is configured for alpha-numeric passwords and the password has consecutive
duplicate numbers (“MES33” for example), enter # between the consecutive duplicate numbers
so the radio will not interpret the entry as a letter (“D” in this example).
•
If the radio is configured for numeric-only passwords, do not enter # between duplicated
numbers.
5. Press the # key twice.
16
MM-011553-001
The User ID may be remembered from the previous log-in. (Refer to Section 6.5 for further details
regarding log-off commands.) The password will be established before the radio is put into operation.
Contact the local OpenSky network administrator for more information.
If necessary, contact radio system administration personnel for log-in assistance and/or
radio-specific log-in instructions.
6.5
LOG OFF THE NETWORK
The *0## command de-registers the radio. Typically, this is automatically performed when powering
down the radio. Using this method, the User ID is remembered by the radio so only the password is
needed at next log-in. Manually log-off by pressing *0## (requires System Model).
If a user is logged in using encryption features, it is necessary to log-off when encryption is no longer
required.
6.6
TURNING THE RADIO OFF
To turn the radio off, rotate the Power Button/Volume Dial counter-clockwise. In multiple control head
installations, turning off the last powered-up control head will also automatically turn off the radio.
Several user-selected radio settings (i.e., scan mode, pre-set buttons, and side tone levels) are maintained
for the next operational session. At the next radio power-up, maintained settings will automatically
restore, along with the network personality settings. In multiple control head installations, settings are
maintained for each control head position.
If power is abruptly disconnected from the radio prior to executing the correct turn-off
procedure, user-selected radio settings and last-tuned channel information will be lost.
This can extend the time required for the radio to register with the network upon the
subsequent power-up.
6.7
MENU DISPLAY AND CONTROL AREA
Following power-up, the radio display shows the default talk group. Pressing up or down with
changes the display to the next available menu. In many cases, the dwell display automatically re-appears
after no menu buttons are pressed for a short period of time (between 10 and 30 seconds). For some
menus such as the GPS and User ID menus, this does not occur until the user presses a front panel button.
When the dwell display is active, it will change dynamically to reflect the current profile, received talk
group/caller ID (when available), or channel (when enabled).
The radio’s display is highly interactive. It responds in the top and bottom text lines as the user presses
the menu buttons (
and MENU) to scroll through the menu loop and the entries for each
menu. Table 6-4 outlines the basic menu structure.
17
MM-011553-001
6.8
RADIO STATUS ICONS
Status Icons indicate the various operating characteristics of the radio. The icons show operating modes
and conditions (see Table 6-2). The location of icons on the display may vary depending on configuration.
Table 6-2: ICONS and Descriptions

6.9
DWELL DISPLAY
When not engaged in menu selection, the first two lines of the display default to the user-defined display,
known as the “dwell display.” The top line indicates the currently selected talk group. The second line
will display the currently selected profile, caller ID/alias 1 , received talk group, and current channel name.
V-TAC mode or V-TAC channel can be displayed as well on V-TAC installations. Press up or down with
the
ramp control to scroll through and view one of these second line options.
6.10 PERSONALITY
As illustrated in Figure 6-3, a personality defines the profiles and talk groups available to the user. It is
the structuring of a collection of profiles and privileges established by the OpenSky network administrator
to provide the user with a comprehensive set of profiles to communicate effectively with the necessary
talk groups or individuals.
Personalities are stored on the network and downloaded over-the-air to the radio. This process is called
“provisioning.” Provisioning occurs at radio power-up and at user log-in. Each personality can contain up
to sixteen (16) profiles and each profile can contain up to sixteen talk groups.
6.10.1
Profiles
As stated above, each profile can contain up to sixteen (16) talk groups. A profile also defines the radio’s
emergency behavior. All transmissions are made on the selected talk group (displayed on the top line of
the dwell display). The user can change the selected talk group to any of the other talk groups within the
profile.
Alias is a logical ID name such as “J_Smith.” The name corresponds to a user ID such as 003-542-0001.

Talk Groups
A talk group represents a set of users that regularly need to communicate with one another. There can be
any number of authorized users assigned to a talk group. Talk groups are established and organized by the
OpenSky network administrator. An OpenSky talk group is similar to a channel within a conventional FM
radio system.
6.11 ALERT TONES
The M7200 radio also provides audible Alert Tones or “beeps” to indicate the various operating conditions (see
Table 6-3).

No V-TAC-related menus are displayed on non-V-TAC radios/control heads.
The “Vchan Menu” is only displayed if the V-TAC is in the SOI mode.
If a V-TAC is in an Extended Coverage mode (XCOV or XCOV-TG), the number of
portable radios (“clients”) connected to the V-TAC is displayed in the bottom line of the
dwell menu.
If a V-TAC is in the Extended Coverage for talk groups mode (XCOV-TG), the selected
talk group and profile in use is displayed.
6.13 DUAL-TONE MULTI-FREQUENCY
Dual-Tone Multi-Frequency (DTMF) is the system used by touch-tone telephones. DTMF assigns a
specific tone frequency to each key so a microprocessor can easily identify its activation. The radio
supports DTMF with a system model control head (Figure 6-1). This allows for specific tasks such as
entering a user ID and password, or selective calling.
When a key on the DTMF keypad is pressed, a single low-pitched tone will be heard from the
microphone. The key tones are not adjustable.

6.14.1
Password Entry
Password entry requires a system model control head. Password characters are encrypted on the display
using symbols to indicate the entry. The encryption symbols for each entry will appear in the display as
they are scrolled through, for example: '-' and '+'. Press the # key twice to complete the entry process.
If the password is wrong, the radio will not successfully register with the network for
wide area voice reception. The radio can still be used in single-site mode.
6.14.2
DTMF Overdial
Using the keypad on a System Model, the radio can transmit DTMF tones corresponding to
numbers/characters 0 — 9, * and # on the keypad. To overdial numbers/characters, transmit by pressing
and holding the PTT button and then, press the corresponding keys (one at a time) on the keypad.
6.15 CHANGING THE ACTIVE PROFILE
The radio can store up to sixteen (16) standard profiles, one of which is the currently active profile. To
change the currently active profile:
1. Press up or down using
2. Use
until “ProfileMenu” is displayed.
to scroll through the list of available profiles.
3. Profile becomes active when selected for longer than 2 seconds, when the MENU is pressed, or when
the menu is changed using
6.16 CHECKING OR CHANGING THE SELECTED TALK GROUP
Each profile stored in the radio can have up to sixteen (16) talk groups. One talk group within the
currently active profile is set as the “selected talk group.” For the radio user, the selected talk group is
typically the focus of most voice transmissions and receptions. There are two ways to change the selected
talk group:
First Method:
1. Use
to scroll through the menu until “TalkGrpMenu” appears on the bottom line of the
display. The currently selected talk group appears in the top line of the display.
2. Use

6.17 ADJUSTING DISPLAY & BUTTON BACKLIGHT BRIGHTNESS
The radio uses a light sensor on the front panel to automatically adjust display brightness and button
backlight brightness to ambient light conditions. The display and backlights automatically brighten at
higher external light levels and automatically dim at lower external light levels. However, the “Bright
Menu” gives the user some manual brightness control as follows:
1. Using
, scroll through the menu until “Bright Menu” appears.
to increase or decrease brightness. Display and button backlight brightness will

immediately dim or brighten.
6.18 STEALTH MODE
For some users, it is important to be able to turn off the radio’s display lights, button backlighting, volume
and side tones, but not the radio traffic. For example, in covert operations, lights and sounds could
inadvertently expose an otherwise unobservable radio user. For this purpose, the radio has a Stealth
feature that disables the radio display light, indicator light and audible side tones.
When stealth mode is on, the radio continues to scan the programmed list of talk groups and the user can
key-up on the selected talk group.
6.18.1
1. Using
Enabling Stealth Mode
, scroll through the menu until “StealthMenu” appears.
2. To immediately turn stealth mode on, press up or down with
3. To turn stealth mode off, press any button on the radio’s front panel.
6.18.2
Disabling Stealth Mode
Pressing any radio button other than the mic’s PTT button or the emergency button on front panel will
immediately turn stealth mode off. For example, pressing the MENU button on the front panel will turn
stealth mode off.
With stealth mode on, pressing any radio button (other than the mic’s PTT button
or the emergency button) on front panel will immediately turn stealth mode off.
6.19 ADJUSTING SIDE TONE AUDIO LEVEL
The radio sounds confirming tones called “side tones” when its buttons are pressed. Most users find this
audible confirmation helpful when navigating the menus. Side tone audio level can be adjusted or turned
completely off using the “Side Menu.”
For covert operations, it may be necessary to turn off side tones. For safety’s sake, turning off the radio
during covert operations is not recommended.
To temporarily disable the side tones that could expose the user’s presence and position, use the menu
buttons to access the “Side Menu” and select “Off” from the menu choices.
25
MM-011553-001
If the radio is operating properly but side tones are not heard when the menu buttons are pressed, the side
tones are probably turned off. To turn them back on, access the “Side Tone” menu and select a setting
other than “off.”
Use the following procedure set side tone level:
1. Use

6.21 RECEIVING AND TRANSMITTING VOICE CALLS
As soon as the radio completes the startup/log-on/provision/self-test sequence and registers on the
OpenSky network, voice calls from talk groups in the active profile will be audible.
6.21.1
Receiving a Voice Call
No action is required to receive a voice call. The display responds to incoming voice calls as follows:
•
If the dwell display is set to received talk group/caller ID/alias, the display indicates either the User
ID of the incoming caller, if available, or the talk group’s name. If the selected talk group matches the
receive talk group, caller ID/alias is displayed. Otherwise, the talk group (name) is displayed.
•
If the dwell display is not set to received talk group, the display indicates the data appropriate to those
displays, but provides no indication as to the identity of the incoming caller.
Refer to Section 6.25 for detailed information on talk group scanning. Refer to Section 6.30 for detailed
information regarding sending and receiving encrypted calls.
6.21.2
Transmitting a Voice Call
Transmit a voice call as follows:
1. Turn the radio on.
2. If required, log-in to the network using a user ID and password. See Section 6.4 beginning on page 16
as necessary.
3. Select the desired talk group for transmitting on.
4. Depress and hold the Push-to-Talk (PTT) button on the hand-held microphone, pause for a moment,
and then speak normally. For maximum clarity, hold the microphone approximately 1 ½ inches from
the mouth and do not shout or whisper into it. If the call is queued by the network, wait for the grant
tone to sound before speaking.
26
MM-011553-001
5. Release the PTT button when finished speaking.
Refer to Section 6.30 for detailed information regarding sending and receiving encrypted calls.
6.22 ADJUSTING AUDIO TREBLE LEVEL
The tone of received signals can be adjusted using the radio’s “Treble Menu” as follows:
to scroll through the menu until “Treble Menu” appears. The radio’s current treble level
1. Use
setting indicates in the top line of the display. There are four levels available: low, medium, mediumhigh and high.
2. Use
to increase or decrease.
3. Press the MENU button or wait a few seconds to return to the Dwell Display.
6.23 INTERCOM MODE
The optional intercom mode gives users at multiple control heads connected to the same radio the ability
communicate with each other without transmitting over-the-air. Turn intercom mode on and off using the
“INTERCOM” menu as follows:
1. Use
to cycle through the available menu items until “INTERCOM” appears in the display.
2. Use
to toggle between “On” and “Off.”
When intercom mode is turned on:
•
Incoming voice calls will override intercom communications for the duration of the voice call. The
radio and associated control heads will remain in intercom mode and intercom communications will
resume when the voice call ends.
•
“TG: INTERCOM” appears in the control head’s display when talking on the intercom. This indicates
microphone audio is not sent out on the selected talk group; rather, it remains localized between the
radio control positions (i.e., the control heads connected to the mobile radio).
•
If a call exists on the currently selected talk group when a PTT button is pressed at one of the control
heads, “TG: in use” appears in the display to indicate intercom mic audio cannot preempt the call on
the talk group.
CAUTION
A user at a radio with only one control head/front panel can turn intercom mode on. In
this case, pressing the microphone’s PTT button will not send microphone audio
anywhere.
6.24 TALK GROUP LOCK OUT
There are two ways of focusing voice communications by suppressing calls from talk groups in the
currently active profile:
1. No Scan. By turning scan off (selecting “No Scan” via the “ScnModeMenu”), only the selected talk group is
audible.
2. Lock Out. By locking out selected talk groups, the “chatter” of the locked-out talk groups cannot be heard. This
focuses the user’s scanning resources to calls only on desired talk groups.
27
MM-011553-001
Talk group lock out is a scan-related feature. With lock out, one or more talk groups in the active profile
can be temporarily disabled from being scanned. Calls are not received on locked-out talk groups. Lock
out settings are not retained between profile changes or when the radio is power cycled.
Lock out is a listening (receive) function and only blocks received calls on locked out
talk groups. Lock out does not affect transmit capability. The above methods do not
apply to recent emergency lock outs.
Only talk groups in the active profile can be locked out, since they are the only talk groups whose voice
calls can be heard on the radio.
If the Scan Mode is “Fixed,” P1 and P2 groups CANNOT be locked out. See Section
6.25 for more information.
The default emergency and emergency-capable talk groups can be locked out if they are NOT in an
emergency state. If a talk group is locked out and is subsequently changed to the currently selected talk
group, it will automatically be unlocked by the radio so the user can hear calls on the talk group. The
radio may be configured so all talk groups are automatically locked out by default. In this case, they must
be manually unlocked, if desired.
6.24.1
Lock Out a Talk Group
1. Use
to scroll through the menu until “LockOutMenu” appears in the bottom line of the
display. The name of a talk group in the currently active profile will appear in the top line.

3. Press the MENU button to lockout the displayed talk group. A less than symbol (<) appears next to the
talk group’s name.
4. Repeat steps 2 and 3, as needed, to lockout additional talk groups.
The dwell display will re-appear a few seconds after button presses end.
While scrolling through talk groups in the active profile, the only talk groups that appear in the
“LockOutMenu” are those in the active profile.
6.24.2
Unlock a Talk Group
1. Use

6.25 SCANNING
Three scanning modes are available for the radio, but only one can be active at any time. Changing the
scanning mode changes the way the radio scans voice calls for all of profiles in the radio personality, no
matter which profile is or becomes active.
As described in Table 6-6, the choice of scanning mode changes the span of communications with all the
talk groups in the radio’s profiles, but does not affect interaction with the talk groups.

6.26 MAKING SELECTIVE CALLS
Selective calling is a feature that allows two radio units to obtain and utilize an independent voice path for
a private call. Radios can be configured to both initiate and receive selective calls or to only receive
selective calls.
In the OpenSky system, a source radio can be configured to initiate selective calls through a preprogrammed list in memory. This method uses the “speed dial list” set up by the OpenSky network
administrator and provisioned as part of the registration process.
In addition, a properly equipped source radio can initiate a selective call to any radio in the system by
entering the ten-digit voice user ID (which looks like a telephone number) of the target device. Entering a
selective call number without using the speed dial feature requires a system model control head (Figure
6-1). See Section 6.13 for more detail.
Selective calls are terminated if an emergency is declared. The network limits selective
calls to ten (10) minutes maximum.
6.26.1
Manually Dialing a Selective Call (System Model Control Head)
1. Press *8 on the keypad.
2. Enter the number of the radio to be called (e.g., 027-001-0006). If the region number (first 3 digits;
027 in this example) is the same as this radio’s region number, these digits do not need to be entered.
Likewise, if the region and agency numbers (first 6 digits; 027-001 in this example) are the same as
this radio’s numbers, these digits do not need to be entered. Leading zeros can also be ignored.
3. Press and release the # key.
4. Wait approximately two (2) seconds.
5. Press and release the PTT button to initiate the selective call request. When the called party accepts
the call, press the PTT again and begin speaking.
6.26.2
Speed Dialing a Selective Call
Speed dial numbers are defined and provisioned by the OpenSky network administrator
and cannot be manually entered into the radio by the user. Contact the administrator if
changes to the speed dial list are required.
1. Scroll through the Menu options using

a. The ring tone is sounded.
b. If the other user accepts the call, the called user’s alias will appear in initiating caller’s display.
The two are now in a private call until one ends the call, the call is terminated due to an initiated
emergency, or the maximum time limit of ten (10) minutes is reached.
4. To end the call, press the MENU button.
6.26.3
Receiving a Selective Call
When someone calls in from another radio using the selective call function, a ring will sound in the
speaker and/or headset. Use the + ramp control to answer the call and press the microphone’s PTT button
when speaking (transmitting) to the caller. Press the MENU button to end the call.
A selective call will be interrupted if an emergency is declared on a monitored talk group.
6.27 SELECTIVE ALERT
Selective alert messaging is an OTP feature allowing one of up to eight (8) pre-programmed text
messages (refer to Section 6.27.3) to be sent from one radio to another. The user specifies a destination
radio’s User ID, selects one of the pre-programmed text messages, and then transmits it to the destination
radio. The message delivery system adds time-of-day information and forwards the message to the
destination (receiving) radio. The sending radio receives a brief message noting the status of the
transmission. Refer to Table 6-7 for a list of possible status messages.
The first few characters of a message are part of the message text entered when the message is
programmed. This programming is performed by the system or network administration personnel.
Messages successfully received by the destination radio are stored in it until read or until it is power
cycled.
6.27.1
Sending Selective Alert Messages
The destination radio’s User ID can be selected via the menu or via the keypad on the system model
control head.
Menu Button Method:

Defining Pre-Programmed Messages
All selective alert messages are pre-defined by the radio system’s maintenance personnel. These messages
are sometimes referred to as “canned” messages. Custom selective alert messages cannot be created by
the radio user. The entire selective alert message, including the abbreviation, can include up to two
hundred (200) text characters.
6.28 TELEPHONE INTERCONNECT CALLS (SYSTEM MODEL CONTROL
HEAD)
If the radio system is equipped with Public Switched Telephone Network (PSTN) interconnect
equipment, telephone calls can be made from the M7200 using this procedure:
1. Press the *9 keys.
2. Enter the telephone number. (Ignore dashes/spaces, and precede the number with any required access
digits such as a 1 for long distance.)
3. Press the # key.
4. Wait a few seconds and then press and release the mic’s PTT button to initiate the call. An initial ring
tone plays indicating call initiation. Once the gateway picks up the call, the ring tone changes.
5. When the caller answers, depress the PTT button when speaking and release it to listen to the caller.
6. To hang-up, press the MENU button on the front panel.
6.29 EMERGENCY COMMUNICATIONS
The M7200 mobile radio can transmit both emergency voice calls and emergency alerts over the entire
network. OpenSky handles emergency calls and alerts with the highest priority.
For critical voice communications, an emergency call can be raised on the default talk group or the
currently selected talk group by “declaring” an emergency on the talk group. The exact talk group is
determined by the currently active profile. After successfully declaring an emergency on a talk group, the
declaring radio’s microphone remains “hot” for a predetermined amount of time. In other words, the radio
transmits audio for a period of time even when the microphone’s PTT button is not depressed. An
emergency talk group is provided greater priority and infinite hang-time by the radio system’s
infrastructure. Hang-time is the maximum duration of quiet time between transmissions on the talk group
before the infrastructure assets are automatically taken away. Because an emergency call is handled on a
talk group, it is received by all radios and consoles monitoring the talk group.
An emergency alert is a data message sent by the radio to the MIS console (or any console capable of
receiving it). It identifies the radio declaring the emergency, and the radio’s location (if the radio is
equipped with a GPS receiver). Voice audio is not automatically transmitted during the emergency if the
administrator configures the radio for alert notification only.
6.29.1
Declaring an Emergency Call or Alert
To declare an emergency call or emergency alert, press and release the orange Emergency button. This
button is located just to the right of the 5-button Menu and Select keypad; see Figure 6-1 on page 14.
Note the following:
33
MM-011553-001
•
The OpenSky network administrator determines if the Emergency button is used to declare an
emergency call or if it is used to declare an emergency alert. This is based upon the radio’s currently
active profile.
•
The OpenSky network administrator also determines if the emergency is declared on the currently
selected talk group or a “default” emergency talk group. Again, this is based upon the radio’s
currently active profile. A talk group upon which an emergency is declared on is considered an
“emergency talk group.”
•
Upon successful emergency declaration:
¾
An emergency tone will sound in the radio’s speaker/headset if the radio is not in stealth mode.
¾
At the declaring radio, the Emergency button flashes red if the radio is not in stealth mode. The
administrator can configure the radio to automatically transmit upon successful emergency
declaration, at which point the MENU button will flash red. However, the MENU button flashing
red is not a requirement for successful emergency declaration.
¾
For an emergency call declaration, “EMERGENCY” indicates in the bottom line of the display.
In addition, the emergency talk group’s name appears in the top line of the display, followed by
an asterisk (*). The emergency talk group can be forwarded across the OpenSky network for
emergency communications.
¾
For an emergency alert declaration, “EMERG ALERT” indicates in the bottom line of the
display.
¾
For an emergency call declaration, other radio users and/or dispatchers at consoles will hear the
emergency signal, a distinctive 3-tone burst. They will also hear audio from the declaring radio’s
“hot” microphone, if any.
¾
For an emergency alert declaration, only dispatchers at consoles will hear the emergency signal
and, if any, audio from the declaring radio’s “hot” microphone.
¾
For an emergency call the declaring radio’s microphone remains “hot” for a predetermined
amount of time. In other words, the radio transmits audio for a period of time even when the
microphone’s PTT button is not depressed. Audio is transmitted over the emergency talk group.
When the microphone is “hot” for this initial period (typically ten seconds), simply speak into it
for voice transmission.
If an emergency declaration is not successful, the radio will periodically re-attempt until it is successful.
During this retry period, the radio will flash “EMERG PEND” on the bottom line of the display. It will
display “EMERG RETRY” for each attempt.
6.29.2
Silent Emergency
When this feature is enabled and an emergency call or alert is declared by pressing the emergency button,
the radio will not play a tone and will display an abbreviated emergency message (default is EBA). This
feature is enabled or disabled via programming or via the menu.
If the Silent Emergency feature is enabled or disabled via programming, the setting will
survive power cycle. Enable/Disable selection via the menu will NOT survive power cycle
and the enable/disable state will revert to the programmed setting at power up.
34
MM-011553-001
6.29.3
Clearing an Emergency Call or Alert
To clear an emergency, press and hold the Emergency button for at least three seconds. However, this can
only be accomplished at the radio where the emergency was originally declared (the initiating radio), by a
dispatcher at a console, at a supervisory radio, or by the network administrator. When the emergency is
successfully cleared, the remove tone will sound at the initiating radio. Also, for an emergency call, the
asterisk (*) will clear from the display.
6.29.4
Receiving an Emergency Call
Upon receiving an emergency call declared by another radio:
•
An emergency tone sounds in the radio’s speaker/headset (three short high-pitched beeps).
•
“EMERGENCY” flashes in the display if the radio is not in stealth mode.
•
When the emergency talk group is selected, an asterisk (*) follows its name in the top line of the
display. The asterisk identifies the selected talk group is in an emergency state. Some radios may be
programmed by the system or network administration personnel to flash the Emergency button (red)
when an emergency call is received. This occurs only if the radio is not in stealth mode.
•
If scan mode is set to “No Scan” and the emergency was declared on the selected talk group, audio on
the emergency talk group is heard in the speaker/headset. See page 29 for additional information on
“No Scan” operation. Also see the following NOTE.
•
If scan mode is set to “No Scan” and the emergency was declared on a talk group other than the
selected talk group, the emergency talk group (identified by an “*”) must be selected before audio on
it is heard in the speaker/headset.
•
If scan mode is set to “Normal” and the emergency was declared on the selected talk group, the
selected/emergency talk group’s name remains in the top line of the display. Audio on the emergency
talk group is heard in the speaker/headset.
•
If scan mode is set to “Normal” and the emergency was declared on a talk group other than the
selected talk group, the emergency talk group’s name appears in the bottom line of the display. Audio
on the emergency talk group is heard in the speaker/headset.
•
The declaring radio's alias appears in the bottom line of the display when the emergency talk group is
selected.
•
An emergency call can be dismissed as described in the following section.
A radio declaring an emergency on a talk group has a “hot” mic time period of typically
ten (10) seconds just after it declares the emergency. This time period may be adjusted
by system or network administration personnel on a per radio basis.
35
MM-011553-001
6.29.5
Dismissing an Emergency Call
An emergency is dismissed for a configurable amount of time only (default = 5 minutes).
To ignore an emergency call declared by another radio user:
1. Press
until “EmgDismiss” appears in the display.
until the talk group in the emergency state appears, as indicated by an asterisk (*)
2. Press
following the talk group’s name.
3. Press the MENU button.
The emergency dismiss timer is cleared when the emergency is cleared.
6.30 ENCRYPTION
In the OpenSky network, both data and voice use a 128-bit or 256-bit key encryption standard published
by the Federal Information Processing Service (FIPS), called Advanced Encryption Standard (AES). AES
is approved by the U.S. Department of Commerce for encryption of classified materials.
When encryption is enabled on the network, data is encrypted from the MDIS to the Mobile End System
(MES) (e.g., M7200 mobile radio). This form of encryption provides air-link security.
Voice encryption is handled either automatically or manually. Automatic encryption is initiated through
the Unified Administration Server (UAS) for a specific talk group and requires nothing from the user.
Manual encryption is initiated by two or more radio users and requires system model control heads. Both
methods of encryption are discussed in the following sections.
6.30.1
Automatic Encryption
For automatic encryption, a network administrator will select the talk group to be encrypted at the
interface to the UAS. Once the talk groups have been selected and identified as secure, credentials for key
generation are generated automatically by the system and provisioned to authorized users. This process
requires that authorized users login to the network and be authenticated. Encryption keys require no
manual handling and are never sent “in the clear” over any network interface or air-link.
1. “Pls Login” appears displayed in the bottom line of the dwell display.
2. Login normally using the keypad on a system model control head to enter User ID and Password.
If a user is engaged in a call on a talk group encrypted at the network administrator level, “Secure Call”
will appear in the bottom line of the dwell display if the user is logged in to that talk group.
If a secure call is in progress elsewhere and the user has not logged in, the bottom of the dwell display
will alternate between “No Access” and the alias of the radio that is currently engaged in the secure call.
6.30.2
Manual Encryption (System Model)
Two or more users can manually encrypt a call, if enabled, without an established encrypted talk group. A
pre-determined key is required at each radio.
36
MM-011553-001
The key must be pre-determined by the users prior to making a manually encrypted call on
a talk group. It can be between one and sixteen (1 - 16) digits and it is entered into the radio
using the keypad.
If two communicating radios have different (manually-defined) keys, receive audio at each
radio will sound garbled.
With manual encryption enabled, unencrypted radio users on the talk group can still make standard voice
(unencrypted) calls on the talk group. However, if an unencrypted user attempts to transmit on the talk
group when one of the encrypted users is already transmitting on the talk group, the unencrypted radio
will sound a deny tone and “No Access” will appear in the display. Also, the encrypted user can hear
standard unencrypted calls, but cannot respond while still manually encrypted.
Do not set a talk group for manual encryption if it has been set for encryption by the
network administration personnel.
CAUTION
Perform the following to transmit or receive manually encrypted calls:
1. Press *32 on the keypad.
2. Enter the key (up to 16 digits).
3. Press the # key.
4. To end manual encryption, press *33#.
If a user is engaged in a call on a talk group that has been manually encrypted at the radio level, the user
will see “Secure Call” on the bottom of the dwell display.
If a secure (encrypted) call is in progress, and the user has not entered the key, the bottom of the dwell
display will alternate between “No Access” and the alias of the radio that is currently engaged in the
secure call.
Once the user has terminated manual encryption, “UnSecure” appears temporarily in the bottom line of
the dwell display.
6.31 PRESET BUTTONS
The front panel contains three buttons labeled A, B, and C. By holding one of these buttons down for
approximately three (3) seconds, the following current information is saved to the function of that button:
•
Selected talk group
•
Selected profile
•
Selected priority talk group
•
Lockouts
•
Scan mode
•
Intercom mode
Presets are saved and restored to/from non-volatile memory. Changing the User ID (login in as a different
user) will clear the presets since they are stored on a per-user basis. Changing control heads will not recall
presets for the previous control head.
37
MM-011553-001
6.32 DYNAMIC REGROUPING
Dynamic regrouping requires that the network administrator determine which radio users should be
formed into an impromptu talk group to respond to particular emergency conditions.
The administrator will edit the personalities of the affected radios to include an emergency profile and
then page the affected radios to re-register with the network to receive their edited personalities.
In response, affected radios automatically re-register to receive their edited personalities. During reregistration, subscriber equipment will default to the emergency profile selected by the administrator.
6.33 GPS COORDINATES
The radio’s current latitude and longitude coordinates may be displayed using the “GPS” menu. The
following procedure assumes a GPS antenna is connected to the radio and it is receiving adequate signals
from GPS satellites:
1. Press
until the “GPS” menu appears in the bottom line of the display. Current GPS coordinate
latitude and longitude data continuously scrolls in the top line of the display in a
degrees:minutes:seconds format.
2. Use
to change to another menu.
If the internal GPS receiver’s data is expired (30 minutes or more) or unavailable, the radio
uses the serving base station’s coordinates [GPS (Site) is displayed]. The GPS Menu will
also indicate if the data is aged (2 minutes or more) [GPS (Aged) is displayed]
6.34 V-TAC FUNCTIONS
When a mobile radio detects that it is part of a V-TAC configuration, two additional menu items become
available: “Vmode Menu” and “Vchan Menu.” The “Vchan Menu” is available only when a V-TAC is
operating in the special mode referred to as the Scene-of-Incident mode (SOI).
The “Vmode Menu” permits user selection and control of one of four (4) different V-TAC operating
modes:
•
Extended Coverage for Individual Users (display reads “XCOV”)
•
Extended Coverage for Talk groups (display reads “XCOV-TG”)
•
Scene-of-Incident (display reads: “SOI”)
•
Mobile-Only (display reads: “Mobile”)
These modes are described in detail in the following subsections.
6.34.1
Extended Coverage Modes (“XCOV” & “XCOV-TG”)
General Information
In addition to all standard mobile radio operating capabilities, Extended Coverage adds the V-TAC’s
bridging (vehicular repeat) functionality for accessing the OpenSky radio network using connected
portable radios. Each portable radio connected to the V-TAC using Extended Coverage is considered a
“client” on the V-TAC. Extended Coverage benefits (permitted) portable radios since it allows them to
get network connectivity using the V-TAC’s higher transmit output power and better antenna system. In
38
MM-011553-001
addition, dispatchers can communicate with the portable radios (the clients) connected to the V-TAC and
logging recorders can record their tactical communications.
The V-TAC supports two Extended Coverage modes: Extended Coverage for individual users (XCOV)
and Extended Coverage for talk groups (XCOV-TG). Up to eight (8) client radios can connect to the VTAC via the XCOV mode, having fully radio functionality including selective calling and mobile data.
Using the XCOV-TG mode, up to thirty (30) client radios can connect to the V-TAC. XCOV-TG is
designed to support a large number of client radios in a tactical scenario. However, unlike XCOV, radios
connected to using XCOV-TG are limited to communicating only on the XCOV-TG talk group and
emergency communications. Advanced features such as selective calling and mobile data operations are
not available to the XCOV-TG connected clients.
Extended Coverage for Talk Groups (XCOV-TG) is only available in OpenSky radio firmware
versions 9.0 and later.
When operating in an Extended Coverage mode, the V-TAC acts both as a local base station by operating
on a base station frequency plan to communicate with the attached client radios and as a mobile radio by
operating on a mobile frequency plan to connect to the OpenSky radio network. The V-TAC rebroadcasts
voice traffic received from connected client radios, routes the received audio to its speaker, and relays this
voice traffic to the network for distribution to other users. It also routes received audio network traffic to
its speaker and forwards this audio to the connected client radios. However, filtering of some network
traffic can occur.
Extended Coverage mode can be enabled automatically or manually (via the menu). For example, an
automatic mode transition may occur after the vehicle’s operator has removed the portable radio from its
charger within the vehicle. When the V-TAC transitions between the Mobile-Only mode and an Extended
Coverage mode, or between an Extended Coverage mode Mobile-Only mode an a four-beep highmedium-high-medium tone sequence sounds in the speaker (this tone does NOT play during a manual
mode transition). Also, for ten (10) seconds, the V-TAC’s control head flashes “XCOV” if it transitions to
the Extended Coverage for individual users mode, or “XCOV-TG” if it transitions to the Extended
Coverage for talk groups mode, or “Mobile” if it transitions to the Mobile-Only mode (the display does
NOT flash these messages during a manual mode transition). When in the Mobile-Only operating mode,
neither of these mode identifiers appears in the display. XCOV vs. XCOV-TG mode determination
methods are described later. When the V-TAC goes from XCOV mode to Mobile-Only mode, it the tone
sounds and "Mobile" flashes in the display for ten (10) seconds.
In most cases, the V-TAC’s Mobile-Only mode is desired when the vehicle is in motion and an Extended
Coverage mode is desired when the vehicle is stationary (a configurable parameter). The exact method
used for mode selection depends upon the specific radio installation. For example, one
V-TAC radio installation could have a 2-position toggle switch mounted on the vehicle’s dash panel for
manual mode selection, while another could automatically enable an Extended Coverage mode when the
portable radio is removed from its cradle/charger within the vehicle.
Operating the V-TAC in an Extended Coverage mode when the vehicle is in motion
can have serious consequences to system operation and performance and is therefore
not recommended. This condition is sometimes referred to as a “rolling V-TAC.”
CAUTION
If necessary, contact the local administrator and/or radio installation personnel for
mode selection information for a particular installation.
The V-TAC operator has control of the following functions affecting call processing:
39
MM-011553-001
•
Talk group selection
•
Talk group scanning
•
Call preemption of the portable and mobile radio clients (e.g., by the Scene Commander)
The V-TAC takes advantage of OpenSky’s TDMA capability to minimize interference between its local
and network radio links when operating in an Extended Coverage mode (XCOV or XCOV-TG), an
undesirable characteristic of many traditional vehicular repeater systems. However, unlike OpenSky
network radio channels, Extended Coverage supports only one active voice call at a time.
Frequency selection is automatic from a predetermined list of channels. This list is defined as part of the
configuration being available for V-TAC operation. The process is supported by GPS location
information that allows the V-TAC to be aware of its location and choose accordingly from its channel
list. If no Extended Coverage channels have been configured, the V-TAC will remain in Extended
Coverage mode and it will continue to search its V-TAC channel list.
Changing Between Extended Coverage Modes
By default, the specific Extended Coverage mode utilized, either XCOV or XCOV-TG, is determined by
commands sent to the V-TAC and portable radios from the system administrator or radio installation
personnel. In other words, these commands determine which Extended Coverage mode the V-TAC and
radios normally utilize when transitioning from the Mobile-Only mode. Therefore, they also determine
the access method that must be employed at a portable radio to connect to the V-TAC. After commands
of this type are sent to the V-TAC and portable radios, each must be rebooted (powered off and then back
on) before the change will take effect.
However, both the V-TAC and the portable radios can manually override this command-determined
default mode. At the V-TAC, this is accomplished by a selection from the “Vmode Menu”. Manual
override at a portable radio is accomplished by pressing a pre-defined key sequence; refer to the
respective portable radio’s operator manual for exact key sequences required.
Additional XCOV-TG Mode Information
The talk group used for Extended Coverage for talk groups (XCOV-TG) communications is the talk
group that was selected at the V-TAC when it entered XCOV-TG mode.
However, at the V-TAC, the selected talk group and/or profile can be changed to another talk group
and/or profile when XCOV-TG is in use. The selected talk group and profile in effect when the V-TAC
transitioned to XCOV-TG mode will continue to be used to validate portable radio connections and filter
the network voice traffic sent to the portable radios.
The selected talk group and profile in use when the V-TAC transitioned to XCOV-TG mode is displayed
on the bottom line of the dwell menu preceded by an “X-”.
6.34.2
V-TAC GPS Interlock
The V-TAC GPS Interlock feature is enabled or disabled through programming by the system
administrator. If enabled, the V-TAC can transition from XCOV or XCOV-TG to the Mobile Radio mode
of operation based on the location and velocity of the VTAC (provided by GPS) in order to prevent a
rolling VTAC. This capability applies only to XCOV and XCOV-TG mode of operation and does not
apply to Mobile Radio mode or Scene of Incident (SOI) mode.
The distance and velocity required for transition are programmed by the system
administrator.
40
MM-011553-001
The VTAC will transition from XCOV(-TG) operation to the Mobile Radio mode of operation if:
•
The distance traveled by the VTAC exceeds a maximum permissible distance from a reference point.
The maximum distance is configured via programming.
The reference point is the location of the V-TAC based on latitude/longitude provided
by the GPS when the V-TAC first transitions into XCOV(-TG), either directly at
power-up, from V-TAC Mobile Radio mode, or from VTAC SOI mode.
Distance traveled is the current location of the VTAC, based on the latitude/longitude
provided by the GPS, from the reference point.
•
The velocity of the VTAC exceeds a maximum velocity threshold in miles/hour. The maximum
velocity threshold is configured through programming.
Velocity is based on the velocity information provided by the GPS.
If location and velocity information is not provided by the GPS and the VTAC is in XCOV(-TG) mode,
VTAC GPS Interlock processing is suspended. When location and velocity information is provided by the
GPS, VTAC GPS Interlock processing is resumed, taking the first valid GPS position coordinates as the
location reference point and acting immediately on GPS provided velocity.
This is intended to cover the situation where the GPS is not operational. If the GPS is out of coverage, the
last location and velocity information provided by the GPS and will be deemed useable.
When the VTAC transitions from XCOV(-TG) mode to Mobile Radio mode the VTAC will disconnect
all connected clients.
When the VTAC transitions from XCOV(-TG) mode to Mobile Radio mode, an audio and visual
indication is provided to the operator. This indication is identical to the indication of the mode transition
based on the external event switch.
When the VTAC is in Mobile Radio mode, the VTAC can return to XCOV(-TG) mode only by the
external event switch or manually via the control head menu.
If the VTAC is in XCOV(-TG) mode and the VTAC transitions to Mobile Radio due to exceeding the
distance and velocity thresholds, the VTAC will not transition back into XCOV(-TG) mode when it falls
back within the distance or velocity thresholds.
6.34.3
Scene-Of-Incident Mode (“SOI”)
SOI mode is user-selectable using the V-TAC’s the “Vmode Menu.” SOI mode provides a local repeater
function with no network connection. It supports two concurrent voice calls, and it supports
communication between other mobiles and portables.
When using the SOI mode, both the V-TAC and any connected portable or
mobile radios (the clients) are off the OpenSky network. Therefore,
communications with radios and dispatch personnel on the network is not
possible.
Frequency selection is performed manually from a list of pre-defined channels using the V-TAC’s
“Vchan Menu.” The radio indicates the FCC channel number for each in addition to its alpha-numeric
identifier.
In SOI mode, the V-TAC supports the following features:
•
Talk group selection
41
MM-011553-001
•
Talk group scanning
•
Call preemption of the client radios (i.e., Scene Commander can preempt a call from a portable or
mobile radio)
In SOI, an emergency initiated at the V-TAC will preempt a client voice call.
6.34.4
Mobile-Only Mode (“Mobile”)
The Mobile-Only mode is user-selectable from the “Vmode Menu” or the radio can be configured to enter
this mode automatically. When utilized, portable radios (clients) cannot connect to the V-TAC. In this
mode, the V-TAC provides two-way communications and it acts like a standard M7200 mobile radio.
Refer to the following section for instructions on choosing this mode.
6.34.5
Changing V-TAC Mode
Use the following procedure to change between the Mobile-Only mode and one of the three (3) V-TACrelated modes:
1. Press the ▲ or ▼ button until “Vmode Menu” appears in the bottom line of the display. The current
mode appears in the top line (Mobile, XCOV, XCOV-TG or SOI).
2. Press the ◄ or ► button to select another mode.
3. Press the Select button. A yes/no confirmation prompt appears.
4. To confirm the new selection, press ► to toggle to “Y” (yes).
5. Press the Select button.
6.
If the SOI mode was selected, the “Vchan Menu” automatically appears; choose a radio frequency channel
using the ◄ and ► buttons, and confirm by pressing the Select button. If selecting the SOI mode, observe the
WARNING in Section 6.34.3.
Instead of using the “Vmode Menu,” some radio installations may be configured to
automatically enter a V-TAC mode when a dash-mounted switch is flipped or some
other action is performed. For example, the V-TAC can be wired and configured to
automatically enter the XCOV mode when the vehicle’s portable radio is removed
from its vehicular charger. See Changing Between Extended Coverage Modes in
Section 6.34.1 for additional information.
6.34.6
Displaying V-TAC Information
When using a V-TAC mode, repeated depressions of the Select button causes the following information
to appear in the bottom line of the dwell display:
42
•
XCOV and XCOV-TG modes only: Total number of portable radios (clients) currently connected to
the V-TAC.
•
XCOV-TG mode only: Talk group currently used for XCOV-TG communications.
•
XCOV-TG mode only: Profile currently used for XCOV-TG communications.
•
All V-TAC modes: Current V-TAC channel. (Does not apply to the Mobile-Only mode.)
MM-011553-001
•
All V-TAC modes: Currently utilized V-TAC mode (XCOV, XCOV-TG, SOI, or Mobile-Only
mode).

Before using the mobile two-way radio, read this important RF energy awareness and control
information and operational instructions to ensure compliance with RF exposure guidelines.
This radio is intended for use in occupational/controlled conditions, where users
have full knowledge of their exposure and can exercise control over their exposure
to remain below RF exposure limits. This radio is NOT authorized for general
population, consumer, or any other use.
Changes or modifications not expressly approved by M/A-COM, Inc. could void the
user's authority to operate the equipment.
CAUTION
This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide
communications between two or more users over a distance. It uses RF energy or radio waves to send and
receive calls. RF energy is one form of electromagnetic energy. Other forms include, but are not limited
to, electric power, sunlight, and x-rays. RF energy, however, should not be confused with these other
forms of electromagnetic energy, which, when used improperly, can cause biological damage. Very high
levels of x-rays, for example, can damage tissues and genetic material.
MM-011074-001
Experts in science, engineering, medicine, health, and industry work with organizations to develop
standards for exposure to RF energy. These standards provide recommended levels of RF exposure for
both workers and the general public. These recommended RF exposure levels include substantial margins
of protection. All two-way radios marketed in North America are designed, manufactured, and tested to
ensure they meet government-established RF exposure levels. In addition, manufacturers also recommend
specific operating instructions to users of two-way radios. These instructions are important because they
inform users about RF energy exposure and provide simple procedures on how to control it. Please refer
to the following websites for more information on what RF energy exposure is and how to control
exposure to assure compliance with established RF exposure limits:

1.2.1
Federal Communications Commission Regulations
Before it is marketed in the United States, the M7200 V-TAC two-way mobile radio is tested to ensure
compliance with FCC RF energy exposure limits for mobile two-way radios. When two-way radios are
used as a consequence of employment, the FCC requires users to be fully aware of and able to control
their exposure to meet occupational requirements. Exposure awareness can be facilitated by the use of a
label directing users to specific user awareness information. The radio has an RF exposure product label.
Also, this Installation and Product Safety Manual and the applicable Operator’s Manual include
information and operating instructions required to control RF exposure and to satisfy compliance
requirements.
1.3
COMPLIANCE WITH RF EXPOSURE STANDARDS
The M7200 V-TAC two-way mobile radio is designed and tested to comply with a number of national
and international standards and guidelines regarding human exposure to RF electromagnetic energy. This
radio complies with the IEEE and ICNIRP exposure limits for occupational/controlled RF exposure
environment at duty-cycle times of up to 50% (50% transmit, 50% receive), and it is authorized by the
FCC for occupational use. In terms of measuring RF energy for compliance with the FCC exposure
guidelines, the radio’s antenna radiates measurable RF energy only while it is transmitting (talking), not
when it is receiving (listening), or in standby mode.
The M7200 V-TAC mobile two-way radio complies with the following RF energy exposure standards
and guidelines:
•
United States Federal Communications Commission (FCC), Code of Federal Regulations; 47 CFR
§ 2 sub-part J.
•
American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers (IEEE)
C95.1-1992.
•
Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999.
CAUTION
Table 1-1 lists the recommended minimum safe lateral distances for a controlled
environment and for unaware bystanders in an uncontrolled environment, from
transmitting antennas (i.e., monopoles over a ground plane, or dipoles) at rated radio
power for mobile radios installed in a vehicle. Transmit only when unaware bystanders
are at least the uncontrolled recommended minimum safe lateral distance away from
the transmitting antenna.

1.5
COMMON HAZARDS
The operator of any mobile radio should be aware of certain hazards common to
the operation of vehicular radio transmissions. Possible hazards include but are
not limited to:
•
Explosive Atmospheres — Just as it is dangerous to fuel a vehicle while its motor running, be sure
to turn the radio OFF while fueling the vehicle. If the radio is mounted in the trunk of the vehicle,
DO NOT carry containers of fuel in the trunk.
Areas with potentially explosive atmosphere are often, but not always, clearly marked. Turn the radio
OFF when in any area with a potentially explosive atmosphere. It is rare, but not impossible that the
radio or its accessories could generate sparks.
•
Interference To Vehicular Electronic Systems — Electronic fuel injection systems, electronic antiskid braking systems, electronic cruise control systems, etc., are typical of the types of electronic
devices that can malfunction due to the lack of protection from radio frequency (RF) energy present
when transmitting. If the vehicle contains such equipment, consult the dealer for the make of vehicle
and enlist his aid in determining if such electronic circuits perform normally when the radio is
transmitting.
•
Electric Blasting Caps — To prevent accidental detonation of electric blasting caps, DO NOT use
two-way radios within 1000 feet (305 meters) of blasting operations. Always obey the “Turn Off
Two-Way Radios” (or equivalent) signs posted where electric blasting caps are being used. (OSHA
Standard: 1926.900).
•
Radio Frequency Energy — To prevent burns or related physical injury from radio frequency
energy, do not operate the transmitter when anyone outside of the vehicle is within the minimum safe
distance from the antenna as specified in Table 1-1. Refer to Section 1.2 for additional information.
•
Vehicles Powered By Liquefied Petroleum (LP) Gas — Radio installation in vehicles powered by
liquefied petroleum gas, where the LP gas container is located in the trunk or other sealed-off space
within the interior of the vehicle, must conform to the National Fire Protection Association standard
NFPA 58. This requires:
¾ The space containing the radio equipment must be isolated and sealed from the space containing
the LP gas container and its fittings.
¾ Outside filling connections must be used for the LP gas container.
¾ The LP gas container space shall be vented to the outside of the vehicle.
•
Vehicles Equipped with Airbags — For driver and passenger safety, avoid mounting the radio’s
control head (or any other component) above or near airbag deployment areas. In addition to driverside and passenger-side front-impact airbags, some vehicles may also be equipped with side-impact
MM-011074-001
airbags. For occupant safety, verify the location of all airbags within the vehicle before installing the
radio equipment.
1.6
SAFE DRIVING RECOMMENDATIONS
The American Automobile Association (AAA) advocates the following key safe driving recommendations:
1.7
•
Read the literature on the safe operation of the radio.
•
Keep both hands on the steering wheel and the microphone in its hanger whenever the vehicle is in
motion.
•
Place calls only when the vehicle is stopped.
•
When talking from a moving vehicle is unavoidable, drive in the slower lane. Keep conversations
brief.
•
If a conversation requires taking notes or complex thought, stop the vehicle in a safe place and
continue the call.
•
Whenever using a mobile radio, exercise caution.
OPERATING RULES REGULATIONS
Two-way FM radio systems must be operated in accordance with the rules and regulations of the local,
regional, or national government.
In the United States, the M7200 V-TAC mobile radio must be operated in accordance with the rules and
regulations of the Federal Communications Commission (FCC). Operators of two-way radio equipment,
must be thoroughly familiar with the rules that apply to the particular type of radio operation. Following
these rules helps eliminate confusion, assures the most efficient use of the existing radio channels, and
results in a smoothly functioning radio network.
When using a two-way radio, remember these rules:
10
•
It is a violation of FCC rules to interrupt any distress or emergency message. The radio operates in
much the same way as a telephone “party line.” Therefore, always listen to make sure the channel is
clear before transmitting. Emergency calls have priority over all other messages. If someone is
sending an emergency message – such as reporting a fire or asking for help in an accident, do not
transmit unless assistance can be offered.
•
The use of profane or obscene language is prohibited by Federal law.
•
It is against the law to send false call letters or false distress or emergency messages. The FCC
requires keeping conversations brief and confine them to business. To save time, use coded messages
whenever possible.
•
Using the radio to send personal messages (except in an emergency) is a violation of FCC rules. Send
only essential messages.
•
It is against Federal law to repeat or otherwise make known anything overheard on the radio.
Conversations between others sharing the channel must be regarded as confidential.
•
The FCC requires self-identification at certain specific times by means of call letters. Refer to the
rules that apply to the particular type of operation for the proper procedure.
MM-011074-001
•
No changes or adjustments shall be made to the equipment except by an authorized or certified
electronics technician.
CAUTION
1.8
Under U.S. law, operation of an unlicensed radio transmitter within the jurisdiction of
the United States may be punishable by a fine of up to $10,000, imprisonment for up to
two (2) years, or both.
OPERATING TIPS
The following conditions tend to reduce the effective range of two-way radios and should be avoided
whenever possible:
•
Operating the radio in areas of low terrain, or while under power lines or bridges.
•
Obstructions such as mountains and buildings.
In areas where transmission or reception is poor, communication improvement may
sometimes be obtained by moving a few yards in another direction, or moving to a
higher elevation.

INTRODUCTION
The M7200 Vehicular Tactical Network (V-TAC) mobile radio is a high-performance full-duplex dualband digital mobile radio. The M7200 V-TAC provides standard and advanced mobile radio
communication functions, along with three (3) distinct V-TAC-related operating modes. The V-TAC
operates on the following radio systems/standards:
•
700 MHz and 800 MHz OpenSky trunked radio networks using the OpenSky Trunking Protocol
(OTP)
•
800 MHz APCO Project 25 phase I compliant Common Air Interface (P25 CAI) trunked radio
networks
•
700 MHz talk-around communications in accordance with the APCO Project 25 phase I standard
•
Conventional FM repeater-based and FM talk-around voice communications in 700 and 800 MHz
bands
The M7200 V-TAC consists of two similar-type mobile radios coupled together via a special RF
combiner. The main radio is called the Vehicular Repeater Mobile. The VRM provides connectivity to the
trunked radio network. The other radio is called the Vehicular Repeater Base. The VRB is the “base
station” part of the V-TAC. It provides connectivity for portable radios operating near the V-TAC. The
radio is shown in Figure 5-2 on page 24.
The V-TAC and control head exceed many tough environmental specifications included within military
standard MIL-STD-810F, automotive industry standard SAE-J1455, the radio industry standard
TIA/EIA-603, and the radio standard established by the U.S. Forest Service.
This manual contains product safety-related and installation procedures for the M7200 V-TAC mobile
radio with the CH-721 control head. Installation procedures cover the mounting and cabling of the
equipment, as well as the basic testing of the radio and control head. An interconnection wiring diagram
is included at the rear of this manual. Product safety-related information is included in Section 1.
3.1
V-TAC OPERATING MODES
The M7200 V-TAC is based on the M7200 mobile radio platform. It can perform all M7200 full-duplex
radio functions, while at the same time providing an in-band network extension to portable radios that
cannot directly connect to the radio network. Three (3) V-TAC operating modes are available. Two of the
three modes are considered extended coverage modes for the portable radios, and one is a scene-ofincident type mode where the V-TAC operates as a local repeater without network connectivity.
3.1.1
Extended Coverage Modes (XCOV and XCOV-TG)
The two (2) V-TAC extended coverage operating modes include a mode called “Extended Coverage for
individual users” (typically abbreviated “XCOV”), and a mode called Extended Coverage for talk groups
(typically abbreviated “XCOV-TG”). Each portable radio connected to a V-TAC using one of these
extended coverage modes is considered a “client” on the V-TAC. With an extended coverage mode, the
V-TAC functions as a router between the trunked radio network and the portable radios connected to it.
When the V-TAC is operating in the Extended Coverage for individual users mode, up to eight (8)
portable radios (8 clients) can connect to it. These portable radios can operate with all standard radio
functions, including selective calling and mobile data.
When the V-TAC is operating in the Extended Coverage for talk groups mode, up to thirty (30) portable
radios (30 clients) can connect to it. This mode is designed to support a large number of radios in a
14
MM-011074-001
tactical scenario. However, unlike XCOV, radios connected to using XCOV-TG are limited to
communicating only on the XCOV-TG talk group and emergency communications. Advanced features
such as selective calling and mobile data operations are not available to the XCOV-TG connected clients.
For additional information on the XCOV and XCOV-TG modes, refer to Section 12.1 on page 51 of this
manual and/or the radio’s operator’s manual (publication number listed in Section 3.3).
3.1.2
Scene-Of-Incident Mode (SOI)
The V-TAC can also function as a local base station at the scene of an incident. Communications of this
type are supported by a V-TAC operating mode called the Scene-Of-Incident (SOI) mode. Typically, this
mode is used when the V-TAC and the nearby portable radios are outside of the trunked radio network’s
normal coverage area. In SOI mode, the V-TAC operates as a local repeater without network
connectivity. For additional information, refer to the radio’s operator’s manual (publication number listed
in Section 3.3).
3.2
GENERAL INFORMATION
The M7200 V-TAC is designed to operate in a mobile environment, typically within a motor vehicle. It
must be connected to an external transmit/receive antenna such as one mounted to the vehicle’s rooftop or
trunk lid. In high-power mode, the radio’s SMR/NPSPAC channel RF transmit output power is 10 watts
maximum. However, the power limit for 700 MHz interoperability channel operations is 300 milliwatts
maximum. This interoperability channel transmit power limit guarantees the 2-watt ERP (effective
radiated power) limit of the 700 MHz interoperability narrowband channels is not exceeded when the
radio is connected to a 5 dBd gain antenna. Several different types of external-mount antennas are
approved and available for use with the radio, as listed in Table 1-1 and Table 4-2. For additional
specifications, refer to Section 2 on page 12 of this manual.
3.2.1
Equipment Mounting and Control Heads
The M7200 V-TAC is designed for remote mounting in a motor vehicle’s trunk, or some other preferably
unoccupied section in a vehicle, such as a fire truck’s equipment shelf. Typically, only one control head is
connected to the V-TAC. However, up to five (5) heads can be connected to it in a multiple control head
installation. A 3-wire Controller Area Network (CAN) cable provides radio-to-control head(s)
interconnection. Between the radio and control head(s), the CAN link carries digitized microphone and
speaker audio, controlling data such as button presses and radio messages, and user data such as that for a
mobile data terminal connected to serial port of the radio or control head. For proper operation, the CAN
link must be terminated appropriately on each end. In a multiple control head installation, two or more
control heads are interconnected to the mobile radio in a series (daisy-chain) fashion via CAN link cables.
Control heads used with the M7200 V-TAC radio include the CH-721 Scan and the CH-721 System
model control heads. See Figure 9-1 (page 39) through Figure 9-3 (page 40). Both heads feature a large
3-line graphical vacuum-florescent display, front panel controls and buttons for user control of the mobile
radio, an internal high-power audio amplifier to drive an externally-connected speaker, and a front panel
microphone connector. The CH-721 System control head also has a 12-button numeric keypad that
provides Dual-Tone Multi-Frequency (DTMF) keypad functionality and easier operator system/group
selection control at the control head’s front panel.
As shown in Figure 9-3 on page 40, the CH-721 Scan and System model control heads have several
connectors located on the rear panel. These connectors include a DC power connector, two (2) CAN port
connectors used for CAN link interconnections, an external speaker connector, a 9-pin serial port
connector for connecting optional equipment such as a mobile data terminal, and a 25-pin multi-function
connector.
15
MM-011074-001
3.2.2
Operating Power
The radio must be powered by an external +13.6-volt (nominal) DC power source. In mobile applications,
the motor vehicle’s electrical system is utilized as the source of DC power. The control head(s) connected
to the radio is also powered by the same DC power source, but separately fused. When the control head is
powered-up by the operator, it “wakes up” the radio by transmitting data to the radio via the CAN link.
3.2.3
Half- and Full-Duplex Communications
The radio provides half-duplex voice communications, and both half- and full-duplex data
communications. Voice communications are accomplished via a “push-to-talk” (PTT) type microphone
and a speaker connected to the control head.
3.2.4
Serial Port for Connecting Optional Equipment
For data communications, the radio has an industry-standard 9-pin serial interface port for connecting
optional data-type equipment, such as a Mobile Data Terminal (MDT), a laptop PC, a third-party display,
or a key-entry device. This port works seamlessly with equipment from popular manufacturers and offthe-shelf applications. OpenSky employs User Datagram Protocol over Internet Protocol (UDP/IP) data
packet transfers, providing “plug and play” connectivity for data-type devices.
3.2.5
RF Operating Bands
3.2.5.1
Vehicular Tactical Mobile (VRM)
700 MHz operating bands of the V-TAC’s VRM radio (normally used for network connectivity) include
the two 3 MHz wide repeater output bands from 764 to 767 MHz and 773 to 776 MHz, and the two
3 MHz wide repeater input bands from 794 to 797 MHz and 803 to 806 MHz. The mobile can operate
only on the narrowband channels within these bands and, as previously stated, transmit output power is
limited to 300 milliwatts on interoperability channels. Talk-around operation is supported between 764 to
767 MHz and 773 to 776 MHz.
800 MHz operating bands of the V-TAC’s VRM radio include the Specialized Mobile Radio (SMR) and
the National Public Safety Planning Advisory Committee (NPSPAC) radio frequency channels. This
includes the 806 to 825 MHz repeater input band and the 851 to 870 MHz band used for repeater output
and talk-around communications. These bands provide a total of over 830 possible channels spread over
the 806 to 824 MHz mobile transmission and 851 to 869 MHz mobile reception bands. Talk-around
operation is supported between 851 to 869 MHz.
3.2.5.2
Vehicular Repeater Base (VRB)
RF operating bands of the V-TAC’s VRB radio are identical to the VRM operating bands. However, the
RF input (VRB receive) bands are reversed with the RF output (VRB transmit) bands. In addition, VRB
does not operate (transmit or receive) on the 700 MHz interoperability channels.
3.2.6
Built-In GPS Tracking Receiver
The M7200 V-TAC has a built-in Global Positioning System (GPS) tracking receiver. GPS provides
quick and accurate unit location information to dispatchers via the radio network. The GPS receiver
determines the V-TAC’s location and the V-TAC transmits it to the radio network. The GPS antenna may
16
MM-011074-001
be integrated into the mobile transmit/receive antenna (a “combination” antenna) or it may be separate
from the mobile transmit/receive antenna.
3.2.7
Modulation and Speech/Data Compression Technologies
An M7200 V-TAC mobile radio operating on an OpenSky radio network uses Time-Division MultipleAccess (TDMA) digital modulation technology on the radio frequency link. TDMA allows multiple radio
users to share a single RF channel. In addition, a single RF channel can support simultaneous digital voice
and data communications.
OpenSky employs Advanced Multi-Band Excitation (AMBE™) speech/data compression technology
developed by Digital Voice Systems, Inc. When operating on an OpenSky radio network, AMBE gives
an M7200 V-TAC the ability to provide exceptional voice quality via the limited bandwidth of the radio
frequency path, even when the received radio frequency (RF) signal is weak (i.e., even in “fringe” areas).
AMBE is performed by a Digital Signal Processor (DSP) integrated circuit within the radio programmed
to perform an AMBE compression algorithm during mobile transmissions, and an AMBE expansion
algorithm during mobile reception.
APCO Project 25 phase I standard P25 radio systems utilize Improved Multi-Band Excitation (IMBE™)
speech/data compression technology, also developed by Digital Voice Systems, Inc. Like AMBE
technology, IMBE technology allows the M7200 V-TAC to deliver exceptional voice quality, even in
areas where the received RF signal strength is weak. IMBE replicates human speech better than other
voice compression technologies, resulting in better voice quality and better speaker recognition. The
Telecommunications Industry Association (TIA) funded an independent study to evaluate compression
technologies. The findings showed that when compared with other industry-recognized compression
technologies, IMBE provided the highest voice quality. In the study, radio users were asked to listen to
coded speech produced by four different compression technologies operating under a variety of
conditions. The users rated the speech on a scale of one to five, with five being the best quality. Under
each operating conditions, IMBE was rated the best.
Speech compression electronic circuitry—be it AMBE, IMBE, or any other type— is sometimes referred

LOCATING COMPONENTS
Plan the mounting locations of all components (V-TAC radio, control head, antenna, and cables) and
determine the routes for all wiring and cables. Particularly consider the connection of the control head for
planning purposes.
•
Determine the customer’s preferences, if any, for location of components. Comply with these
preferences as long as they are consistent with safety recommendations and guidelines presented in
this manual, and other generally accepted professional radio installation practices.
•
Nominal dimensions for the V-TAC radio are 7.3 x 8.8 x 9.3 inches (18.5 x 22.4 x 23.6 centimeters);
height x width x depth). This includes the base bracket and its mounting tabs, but it does not include
any clearance space required for cabling, air circulation, access to mounting hardware, etc.
•
Verify sufficient clearance behind the units is provided so cables will not be stressed, crushed,
twisted, or bent at severe angles. Also, the front and sides must have clearance for air circulation,
access to mounting hardware, etc.
•
Connections at the V-TAC radio are made through “pigtail” type cables exiting the rear of the radio.
This design minimizes the stresses associated with mating connections and it allows for easy
connector mating. However, stresses can still be induced if adequate service looping is not employed.
Connections to the control heads are made with connectors mounted on the rear panel of each head
instead of “pigtail” type cables.
CAUTION
All cables should have a service loop near each connector end. Do not bend the cables
at severe angles near the connector end. Above all, after all components are installed,
verify no cable is under any tension. Failure to do so may lead to damaged cables,
causing intermittent radio operation or complete radio failure.
25
MM-011074-001
MOUNTING THE V-TAC
This section provides details on mounting the V-TAC mobile radio. See Figure 5-2 and refer to the
respective wiring diagram at the end of this manual as necessary. Control head installation procedures are
included in Section 9 (page 39) of this manual.
The preferred mounting is on top of a firm, flat surface. The V-TAC is a relatively heavy radio, at
approximately 14 pounds. Consider this weight when selecting a mounting surface. Refer to the specifications listed in Section 2.1 (page 12) of this manual for radio and control head weight specifications.
V-TAC Installation Kit MAMV-NZN8B (contents listed in Table 4-1 on page 19)
contains the most complete set of materials for installing the V-TAC. Therefore, the
following instructions make repeated reference to this kit. Item numbers given in
parenthesis refer to items in the kit.
Prior to beginning the installation, verify the V-TAC has the proper version of software
installed and it has been configured for customer usage.
CAUTION
Though generally mounted in a trunk or remote location, the V-TAC must be kept away
from heat sources. Mounting it in a location which is out of direct sunlight is
recommended but not required. Adequate ventilation space must be provided to the rear
and side fins. The V-TAC reduces its RF output power when its ambient temperature
exceeds approximately +140 o Fahrenheit (+60o Celsius).
At a minimum, the mounting surface should be 16-guage (approximately 1/16-inch
thick) steel sheet metal. Mounting to plastic or other material with low tensile and
shear strength could lead to an unsafe and/or failed mounting condition, turning
the V-TAC and its base bracket into a projectile during a high-shock incident such
as a motor vehicle accident. If the selected mounting surface does not meet the
minimum 16-guage steel sheet metal requirement, the surface should be reinforced
with a metal backing plate (not supplied) or it should be reinforced using some
other approved mounting method.
CAUTION
6.1
Before drilling holes and/or installing mounting screws, verify these operations will not
damage or interfere with any existing vehicle component (fuel tank, fuel line,
transmission housing, existing vehicle wiring, etc.). Always check to see how far the
mounting screws will extend below the mounting surface prior to installation. Always
deburr drilled holes before installing screws.
BRACKET INSTALLATION
Typically, the V-TAC’s Base Bracket (Item 1 in Table 4-1) is mounted in the vehicle’s trunk, on the top
surface of the trunk tray or the trunk floor. However, it can be suspended from the trunk’s rear deck if the
surface is completely flat, does not require any shimming and the gauge of deck’s sheet metal is high
(16-guage minimum).
Since the V-TAC protrudes several inches from the bracket’s front and back edges, maintain sufficient
distance at the front and back for this and additional clearance. A minimum distance of three (3) inches is
26
MM-011074-001
required from the rear edge of the bracket; however four (4) inches or more is recommended to improve
V-TAC installation and removal ease. A minimum distance of two (2) inches is recommended from the
front edge of the bracket. The bracket is front/back symmetrical, and left/right symmetrical.
As all installations differ, bracket-to-vehicle mounting screws are not included. Steel #10 self-threading
screws are recommended. Sheet metal screws should not be used. The bracket has ten (10) available
mounting holes; six (6) are underneath the V-TAC when it is attached to the bracket. The following
mounting procedure is recommended:
1. Using the Base Bracket (Item 1) as a template and/or the dimensional information shown in Figure
6-1, mark and drill mounting holes into the mounting surface as required. At least six (6) screws are
recommended for proper installation: Four (4) in the screw holes of the bracket’s side tabs and two
(2) in its center-most screw holes. If the installation prevents the installation of six screws, a
minimum of four screws installed in the side tabs’ holes is required.

2. Deburr all newly drilled mounting holes.
3. Set the bracket in place, and install and tighten the mounting screws.
4. Verify the bracket is firmly secured to the mounting surface. A secure mount prevents unreasonable
vibration, which could damage the V-TAC and/or cause its cable connections to loosen.
6.2
MOUNT THE V-TAC INTO THE BRACKET
The V-TAC should now be mounted into the bracket according to this procedure:
1. Attach the V-TAC into the Base Bracket using three #8-32 pan-head screws (Item 5 in Table 4-1) per
side. Tighten all six screws with a screwdriver until the lock washer on the screws are fully
compressed and the V-TAC is firm and flush in between the brackets.
2. Check the mounting area for proper clearance for cable service looping and for air circulation, plus an
area to secure and rest the excess cable lengths.
Proper mounting is one factor that ensures optimal V-TAC performance. An improperly mounted V-TAC may experience degradation in the quality of voice and data
communications.

ANTENNA INSTALLATION
7.1
ANTENNA MOUNTING LOCATIONS
At this time, review all information presented in the REGULATORY AND
SAFETY INFORMATION section of this manual (begins on page 6). A
transmitting antenna must be installed in accordance with the guidelines presented
in the REGULATORY AND SAFETY INFORMATION section. Use Table 1-1 on
page 8 and Figure 7-1 below as a guide for determining the best possible mounting
configuration/location in order to reduce human exposure to radio frequency (RF)
electromagnetic energy during transmit mode.
Antennas can be mounted in one of there possible locations on the vehicle as described in the following
subsections. Figure 7-1 shows the recommended locations and antenna part numbers for each location.
Also, see Table 4-2 for additional information. Always follow manufacturer’s instructions when
mounting an antenna.

MM-011074-001
7.1.1
Direct Center or Center-Rear of Rooftop
The center of the vehicle’s roof is the best location for the rooftop antenna (❶ in Figure 7-1). For optimal
performance, the mounting area under the antenna must be a flat with a minimum radius of six (6) inches
of metal ground plane. It must be located directly in the center of the roof to minimize human exposure to
RF electromagnetic energy. Other obstructions such as a light bar or another antenna may prevent the
antenna from being mounted in the direct center of the roof. In this case, the antenna should be mounted a
minimum of one foot away from and behind the obstruction but in the middle of the roof with respect to
the left and right sides of the vehicle (❷ in Figure 7-1).
7.1.2
Center of Trunk Lid
Certain vehicles do not allow for the antenna to be placed in the center or center-rear of the roof. In this
case, the next best location for the antenna is in the direct center of the trunk lid (❸ in Figure 7-1). In this
case, an elevated-feed-point antenna is recommended. Although this type of antenna does not require a
metal ground plane, it must be located directly in the center of the trunk lid to minimize human exposure
to RF electromagnetic energy.
The antenna cable of M/A-COM approved antennas should never be cut to a
shorter length. Instead, excess cable must be tied and stowed. This not only
prevents the antenna from radiating above its intended or configured power, but
it also allows for future installation considerations such as a relocation of the
mobile radio within the vehicle. Installations requiring longer cables are to be
treated as custom and separately specified.
7.2
ANTENNA INSTALLATION PROCEDURE
An antenna must be installed before completing the radio installation.
7.2.1
Install and Connect Mobile Antenna
Table 4-2 lists several types of mobile radio antennas available for use with the V-TAC. As presented in
the previous section, various mounting locations exist. Optimal performance is achieved via a rooftop
antenna mounted in the direct center of the motor vehicle’s roof:
1. Once the mounting location is selected, refer to the antenna manufacturer’s assembly, mounting and
testing instructions included with the antenna kit for installation guidance. If necessary, contact
M/A-COM’s Technical Assistance Center (see page 18 for contact information).
2. Route the cable from the antenna to the rear of the V-TAC. The cable should be kept out of casual
contact from persons within the vehicle. Tie and stow as necessary.
Use the full length of coaxial cable included with the antenna. Never cut the cable
to a shorter length, but rather coil any excess. Reducing the length of cable
increases the output power radiated by the antenna, thereby exceeding the
Maximum Permissible Exposure (MPE) allowance regulated by the FCC.
30
MM-011074-001
3. Connect the antenna cable’s TNC plug-type (male) connector to the V-TAC’s TNC receptacle-type
(female) “pigtail” type RF connector at the rear of the V-TAC. Mate the two connectors and turn the
plug clockwise until finger-tight.
This will be a temporary connection until the V-TAC and antenna can be tested after the installation is
complete. The antenna needs to be connected in case of accidental RF transmission.
7.2.2
Install and Connect GPS Antenna
The V-TAC is equipped with a GPS receiver which requires connection to an externally-mounted GPS
antenna if the GPS functions will be utilized. Some installations may use a magnetic-mount stand-alone
GPS antenna installed separately from the SMR mobile antenna.
The SMR/GPS combo antenna kit includes a GPS antenna built into the base of the mobile antenna. No
extra holes are required for the GPS cable when using this antenna. The antenna must be kept at least six
(6) inches away from any other antenna mounted on the vehicle and have at least six inches of surface
ground plane beneath it.
The following antenna installation procedure is recommended:
1. Once the mounting location is selected, refer to the antenna manufacturer’s mounting and testing
instructions for installation guidance. If necessary, contact M/A-COM’s Technical Assistance Center
(see page 18 for contact information).
2. Route the cable from the GPS antenna to the rear of the V-TAC. The cable should be kept out of
casual contact from persons within the vehicle.
3. Connect the GPS antenna cable’s SMA plug-type (male) connector to the V-TAC’s SMA receptacletype (female) “pigtail” type RF connector at the rear of the V-TAC. Mate the two connectors and turn
the plug clockwise. Tighten with a pair of slip-jaw pliers.
Do not attempt to alter the length of cable from the GPS antenna. The SMA connector
on the end of the antenna cable is not field-replaceable. Tie and stow excess cable as
necessary.

MM-011074-001
V-TAC DC POWER INSTALLATION
Refer to the wiring diagram at the end of this manual as necessary when performing wiring procedures
presented in this section. With regards to control head installation, power connections for the CH-721
Scan and CH-721 System control heads are exactly the same.
8.1
ON/OFF POWER WIRING CONFIGURATIONS
The M7200 V-TAC mobile radio can be wired in a motor vehicle in various ways to accommodate the
user’s preferences. In all cases, its red power wire must be connected through an in-line fuse to raw
battery power (positive battery terminal). An in-line switch for switched battery power to the V-TAC
must not be considered unless the user has the discipline to turn off the V-TAC through the control head’s
on/off/volume control or through a separate switch wired to the ignition sense wire. Failure to wait for the
V-TAC to completely power down before disconnecting battery power will not damage the V-TAC;
however, it may result in the loss of settings that have changed (e.g., volume setting, etc.) during the
operating session.
On/Off power functions for the V-TAC are controlled by the control head. The following power wiring
configurations are supported:
8.2
•
V-TAC turns on/off automatically with vehicle’s ignition switch/key — The white sense wire of
the control head’s DC Power Cable is connected to a fused switched power source, typically
identified as “Accessory” power. This source must switch on (up to positive (+) battery voltage
potential) when the vehicle’s ignition switch/key turns on, and it must switch off (to near zero volts)
when the ignition switch/key turns off. The required fuse rating is 2 amperes. An ATM fuse holder
and fuse are included with the applicable fuse kit. When using this configuration, the CH-721 control
head’s on/off/volume control must be left in the on position for automatic power-up/down to function
properly.
•
V-TAC turns on with a manual switch — The white sense wire of the control head’s DC Power
Cable is connected to one side of a manual toggle switch and the other side of this switch is connected
to a fused vehicle power source. This configuration is used when, for example, the V-TAC must
remain on even when the ignition key must be removed from the vehicle and a separate on/off switch
is acceptable. The required fuse rating is 2 amperes if no other devices share the switch. If other
devices share the switch, the 2-ampere ATM fuse must be spliced in the white wire on the
load/switched power side of the switch. When using this configuration, the CH-721 control head’s
on/off/volume control must be left in the on position for automatic power-up/down to function
properly.
•
V-TAC turns on with control head’s on/off/volume control (“hot wired”) — This configuration
allows radio power on/off control only via the control head’s on/off/volume control. It may be desired
if, for example, the V-TAC must remain on even when the ignition key must be removed from the
vehicle and a separate on/off switch is not desired. In this case, the white sense wire of the control
head’s DC Power Cable must be connected to unswitched and fused vehicle power. The required fuse
rating is 2 amperes.
POWER INSTALLATION PROCEDURE
8.2.1
Install Main Fuse Holder and 10-AWG Red Wire
The main power fuse (30-amp), its holder, and related items are included in Fuse Distribution Rail Kit
FS23057 illustrated in Figure 8-1 on page 34. Follow the procedure in this section to wire fused main
power from the vehicle’s battery to the location of the V-TAC and the Fuse Distribution Rail Assembly in
32
MM-011074-001
the vehicle’s trunk. The Fuse Distribution Rail Assembly is installed during the subsequent procedure
(Section 8.2.2). Also refer to the respective wiring diagram at the end of this manual as necessary.
CAUTION
Do not install the fuse holder and the red wire over or in the near vicinity of the
engine. Excessive engine heat can cause permanent damage to these components and
can lead to intermittent electrical connection to the battery.
Before making connections to the battery’s positive post, carefully disconnect the
battery’s negative (ground) cable. This will prevent tools or other metallic objects
which come in contact with the battery’s positive terminal from shorting to
vehicle chassis ground, causing sparks or even a fire or an explosion! When
disconnecting the negative cable, cover/insulate the positive post if it is not
already so a tool cannot short between the posts.
A fuse must not be installed in the main fuse holder until all wiring is complete.
This will prevent the unit from powering up prematurely and/or causing an inrush of current that could lead to shorting of the battery, sparks, or even fire.
1. Strip one of the ATC Fuse Holder’s wires and crimp a 3/8-inch ring terminal to it. Both items are
included in the Fuse Distribution Rail Kit.
2. Verify the fuse is NOT in the Fuse Holder.
3. Connect the ring terminal directly to the battery’s positive post (or if present, to a stud on the battery’s
main/non-switched power distribution terminal block).
4. Strip the Fuse Holder’s other wire, strip one end of the 20-foot long 10-AWG red wire, and then
connect these two wires together using a 10-AWG moisture-resistant butt splice. The red wire and the
butt splice for this connection is included in the Fuse Distribution Rail Kit.
CAUTION
Plan the routing of the 10-AWG red wire carefully, using an existing access hole in the
vehicle’s firewall if possible. Alternately, drill a new hole approximately 3/8-inch in
diameter and install a small rubber grommet to protect the wire from chafing on the
hole’s sharp metal edge. To prevent fumes from entering the passenger
compartment, this hole/grommet/wire combination must also be sealed with a
silicon-based sealer before completing the installation.
5. Route the other (load) end of the 20-foot long red wire through a wire-loom then through the
grommet in the firewall. This load end of the red wire will later be connected to a Fuse Block clipped
on the Fuse Distribution Rail Assembly (both parts of the Fuse Distribution Rail Kit). The Fuse
Distribution Rail Assembly will be located near the V-TAC in the trunk.
6. Continue routing the 20-foot red wire through channels in the vehicle to the location of the V-TAC.
Remove interior panels, door kick panels, etc. Protect the wire from possible chafing where
necessary.
8.2.2
Assemble and Install Fuse Distribution Rail Assembly
The Fuse Distribution Rail Assembly must be completely assembled and installed in the vicinity near the
V-TAC mobile radio. This rail assembly, included in Fuse Distribution Rail Kit FS23057, comes
preassembled with only one (1) Fuse Block on the rail. However, the installation requires two blocks—
33
MM-011074-001
one to fuse the V-TAC and one to fuse the control head. Therefore, the assembly must be partially
disassembled so the Fuse Block and the Fuse Block Jumper from kit FS23058 can be added to the rail
assembly. As shown in Figure 8-1 and Figure 8-2, one Fuse Block is included in kit FS23057
(preassembled to the rail) and one is included in kit FS23058. The completed assembly is shown in the
photo on page 38.
Note: This kit is a part of V-TAC Installation Kit MAMV-NZN8B.
See Table 4-1 on page 19 for descriptions of the kit’s contents (item 2 in the table).

See Table 4-3 on page 20 for descriptions of the kit’s contents (item 6 in the table).
Figure 8-2: Contents of Fuse Distribution Accessory Kit FS23058
The Fuse Distribution Rail Assembly has a DIN-type rail allowing additional Fuse Blocks to be added to
it if fuse expansion is necessary in the future, such as for multiple control head installations. The rail may
be cut to decrease its length if necessary, but enough room for at least one control head and any additional
future expansion should be considered first. Install the rail in accordance with the following procedure:
1. Mount the Fuse Distribution Rail Assembly in the vicinity of the V-TAC’s mounting location, but
where casual contact is not likely. Use self-threading screws (not supplied) and any available
mounting slots in the DIN rail to mount the block.
2. Strip one end of the 10-AWG black wire (included with the Fuse Distribution Rail Kit) and crimp a
3/8-inch ring terminal to it.
3. Near the Fuse Distribution Rail Assembly, locate an area of vehicle chassis ground within
approximately six (6) inches of the assembly and strip the area of any paint or dirt to expose a bare
metal surface.
4. Drill a hole as necessary and connect the ring terminal to chassis ground. Use a self-threading screw
or other appropriate hardware to ensure a reliable metal-to-metal contact. Tighten securely.
5. Cut the black wire to a length long enough to reach a green-yellow Grounding Block on the Fuse
Distribution Rail Assembly, plus length for a service loop. Strip the end to prepare it to connect to a
Grounding Block.
6. The Fuse Distribution Rail Assembly has two greenyellow Grounding Blocks. Each Grounding Block has
two wire-clamps with associated wire-clamp release
slots. As shown in the photo at the right, insert a #1 or
#2 flat-blade screwdriver completely into one of the
wire-clamp release slots. Insert the screwdriver until it is
captured in a vertical position as shown in the photo in
the next step.
35
MM-011074-001
7. Insert the stripped end of the black wire fully into the
wire-clamp beside the screwdriver, and then remove the
screwdriver to lock the wire in the clamp. The adjacent
Grounding Block is electrically connected together, so
this black wire grounds both blocks.
8. Prepare to connect the 10-AWG red wire from the Fuse
Holder at the vehicle battery to the Fuse Block of the
DIN rail assembly by cutting excess length and stripping
the end. Leave enough wire length for a service loop.
9. As shown in the photo at the right, connect the 10-AWG
red wire to the Fuse Block’s supply-side wire-clamp.
10. Obtain the V-TAC’s DC Power Cable (Item 3 in Table
4-1).
11. Mate the cable’s connector to the V-TAC’s 3-pin power
connector as follows: Visually align the key and firmly
push and turn the outer locking ring clockwise until it
stops. A click will be sensed to confirm proper mating.
12. Prepare to connect the cable’s black (negative) and red
(positive) wires to a Grounding Block and to the Fuse
Block by cutting excess length from both wires and
stripping the ends. Leave enough wire length for service
loops.
13. Connect the cable’s red wire to the wire-clamp on the
Fuse Block’s load-side wire-clamp and connect the
cable’s black wire to any one of the wire-clamps on a
Grounding Block.
14. A second Fuse Block must be installed onto the Fuse
Distribution Rail Assembly to supply power to the
control head. Therefore, obtain the second Fuse Block
from Fuse Distribution Accessory Kit FS23058.
15. As shown in the photo at the right, remove the End Stop
next to the original Fuse Block on the DIN rail by prying
at its side release with the screwdriver.

16. Hook the second Fuse Block’s rail clip onto the DIN rail
next to the original Fuse Block and snap it in place.
When installed correctly, the Fuse Blocks will snap
themselves together as well.
17. As shown in the photo at the right, install the Fuse Block
Jumper into adjacent slots of the two Fuse Blocks. DC
power distribution occurs through the jumper; therefore,
daisy-chaining of the supply-side wire-clamps is not
required. The Fuse Block from the Fuse Distribution
Accessory Kit has a protection marker installed on the
supply-side of the block to warn of inappropriate wire
installation in its supply-side wire-clamp.
18. Press the Fuse Block Jumper firmly in place as shown in
the photo at the right.
19. Reinstall the End Stop by hooking its rail clip onto the
DIN rail and snapping in the other side. Make sure it is
firmly against the second Fuse Block.
37
MM-011074-001
20. Install two ATC-type fuses into the Fuse Blocks. The
V-TAC mobile radio requires a 20-amp fuse (fuse
color = yellow) and the control head requires a
5-amp fuse (fuse color = tan). Install the correct fuse
into the correct Fuse Block based upon the wire
connection at the load side of each block!

21. Tie and stow all cables and wires as necessary so they
remain out of the way of casual contact, and so wire
chafe is avoided.
The photo at the right also includes red and black wires for
control head power. These wires are connected during a later
procedure in this manual.
SUPPLY-SIDE
(from 30-Amp Fuse)
22. Apply the sticker included in the Fuse Distribution Rail Kit in the vicinity of the Fuse Block as
future reference for service personnel.
23. Route the V-TAC DC Power Cable’s white wire to the vehicle’s fuse box and label it accordingly.
Tie and stow the wire as necessary so it remains out of the way of casual contact and wire chafe is
avoided.
The control head wakes up the V-TAC via the CAN port when power is applied.
However, connection of the V-TAC DC Power Cable’s white sense wire may be
needed in future configurations that do not use the control head. Therefore, it is
recommended that the white wire be labeled, routed up to the vehicle’s fuse box,
coiled, and stowed for possible future use rather than be cut from the DC Power Cable.
CAUTION
CAUTION
Installing a fuse with the wrong amperage rating could cause an unsafe condition
and/or a prematurely blown fuse. Verify the correct fuse value for the V-TAC is
installed. The color of the 20-amp fuse is yellow.
The fuse for the control head is rated at 5 amperes. Installing the wrong fuse value
could lead to damage. Verify the control head is wired to the 5-amp (tan color) ATC
fuse!
When servicing the V-TAC and/or control head, always manually turn all units off and
then pull the main power fuse in the engine compartment.
CAUTION

CONTROL HEAD INSTALLATION
9.1
GENERAL INFORMATION
Since the M7200 V-TAC is a remote-mount mobile radio, it must be connected to a control head to
provide the operator-to-radio interface. Two different control heads are available—the CH-721 Scan
model and the CH-721 System model. See Figure 9-1 and Figure 9-2 respectively. The CH-721 Scan
model control head features three (3) large menu selection buttons. The System model control head has a
12-button keypad to allow advanced operations without the need of a DTMF-capable microphone.
Figure 9-3 on page 40 illustrates the rear panel of the two control head models. Both models have
identical rear panels and rear panel connectors.

Prior to installing the control head, verify it has the proper software version installed and
verify it has been properly configured for customer use.
Because the Control Head Installation Kit MAMV-ZN7N contains the most complete set
of materials for installing the control head, the following instructions make repeated
reference to this kit. Item numbers given in parenthesis below refer to items in the kit.
See Table 4-3 on page 20 for a complete listing of kit contents.
In a mobile installation, more than one control head can be connected to a V-TAC mobile radio for multihead installations. A multi-head installation may be required in a vehicle such as a fire truck or any large
vehicle where more than one operator may require use of the V-TAC. Multi-head installations also
provide other benefits such as intercom functionality.

CONTROL HEAD MECHANICAL INSTALLATION
9.2.1
Selecting the Mounting Location
When selecting a location for the CH-721 control head, first observe the safety and operator-convenience
related information presented in Section 5.1 on page 22. Also always consider and include clearance for
the microphone’s connector that must mate to the mic connector on the front panel of the head, and
clearance for the connectors/cables that must mate to the connectors on the rear panel of the head. The
CH-721 control head can be mounted under or on top of a mounting surface (typically the vehicle’s dash)
as space permits using either the standard U-shaped mounting bracket or the optional mounting pedestal.

9.2.2
Using the Standard U-Shaped Mounting Bracket
If the standard U-shaped Mounting Bracket will be used to mount the control head, the following
mounting procedure is recommended. This bracket is included with the Mounting Bracket Kit listed in
Table 4-3 (page 20).
1. Using the Mounting Bracket as a template, mark and drill mounting holes into the mounting
surface as required. The round and elliptical holes in the bracket’s vehicle mounting surface are
symmetrical so forward/backwards positioning is not important during this step. However,
positioning is important in the next step.
CAUTION
When drilling holes, be careful to avoid damaging some vital part of the vehicle (fuel
tank, transmission housing, etc.). Always check to see how far the mounting screws
will extend below the mounting surface prior to installation. After drilling pilot holes,
remove all metal shavings from them (i.e., deburr the holes) before placing the bracket
and installing the mounting screws.
2. Postion the bracket at the mounting surface so the two round holes in its two side “ears” are
nearest to the normal location of the operator (typically towards the rear of the vehicle) and the
two slotted holes are furthest from the normal location of the operator (typically towards the front
of the vehicle).
3. Install and tighten the mounting screws. Screws for mounting the bracket to the mounting
vehicle’s surface are not included, as all installations differ. Self-threading screws are
recommended. Sheet metal screws should not be used.
4. Verify the bracket is held firmly to the mounting surface. Firm mounting prevents unreasonable
vibration, which could damage the control head and/or cause its cable connections to loosen.
5. Slide the control head into the bracket, placing the two pegs protruding from its left and right
sides into the respective round holes in the bracket’s two side “ears.”
6. In each side “ear” of the mounting bracket, start a #8-32 socket-head cap (Allen) head screw with
a lockwasher and a flat washer by inserting the screw through the slotted hole in the bracket and
then into the threaded hole in the side of the control head. This hardware is included with
Mounting Bracket Kit. The lockwasher should be adjacent to the screw head and the flat washer
should be adjacent to the bracket. Turn each screw clockwise as observed from the head of the
screw.
7. The control head can be positioned at various angles for best display viewing at the normal
position of the operator. As necessary, turn it on the pegs to a good position and tighten both
screws using an 1/8-inch hex key (Allen) wrench until the control head is held firmly in place. Do
not over-tighten.
9.2.3
Using the Mounting Pedestal (Optional)
An optional Mounting Pedestal, part number MACDOS0012, may be purchased separately to replace the
standard U-shaped Mounting Bracket. This pedestal can be attached to the bottom of the control head as
shown in Figure 9-5 and then mounted to a mounting surface below the two. It can also be attached to the
top of the head and then mounted to a mounting surface above the two.

CAN CONNECTIONS
9.3.1
General Information
The installation requires a CAN cable between every two “CAN devices” and CAN terminators on each
end of the CAN link. The M7200 V-TAC mobile radio is considered a CAN device, and each CH-721
control head in the installation is also considered a CAN device. Figure 9-6 illustrates CAN cable and
CAN terminator connections for a single control head installation. Figure 9-7 illustrates this for a multihead control head installation where, for example, one control head is located at the main operator
location and another is located near the rear of the vehicle. Because CAN devices do not have internal
terminators, the CAN link must be terminated at both ends via a CAN terminator.

Figure 9-7: Typical CAN Link Connections for a Multi-Control Head Installation
43
MM-011074-001
Both the V-TAC and the control head have two CAN ports to support “daisy-chaining” of multiple
control heads or other CAN devices. Figure 5-2 on page 24 shows the V-TAC’s two CAN port
connectors, which are located on cable side of the I/O cable’s DB-44 connector. Figure 9-3 on page 40
shows the two ports on the control head’s rear panel.
9.3.2
Make CAN Link Terminations and Cable Connection
Follow this procedure for an installation which has only one control head. For a multi-control head
installation, refer to Figure 9-7 presented in the previous section as necessary.
1. Connect the CAN Terminator (Item 3 in Table 4-3) onto either one of the two smaller 3-pin
connectors on the rear of the CH-721. This action makes the CAN termination at the control head
end of the CAN link.
When mating any CAN connection (terminators and cables), visually align the
¾-moon-shaped keys of the connectors, and then gently push and turn the outer
locking ring of the plug (male) connector clockwise until it stops. A mild click will be
sensed to confirm proper mating. Without visual alignment as a guide, it is possible
with excessive force to mate the CAN connectors improperly. Damage to the
connector(s) may result. Therefore, visual alignment is recommended when mating
CAN connectors.
2. Route the CAN Cable (Item 4 in Table 4-3) through the vehicle’s interior wire/cable channeling to the
V-TAC. Remove interior panels, door kick panels, etc., as necessary. Protect the cable from possible
chafing as necessary.
3. Attach the CAN Cable’s connector to one of the two CAN port connectors on the V-TAC’s I/O cable.
4. Connect the other end of the CAN Cable to the open CAN port connector at the rear of the control
head.
5. Connect the CAN Terminator (Item 4 in Table 4-1) onto either one of the two smaller 3-pin
connectors on the V-TAC’s I/O cable. This action makes the CAN termination at the V-TAC end of
the CAN link.
6. Loop, tie and stow the excess cable as necessary.
9.4
CONTROL HEAD POWER CABLE INSTALLATION
Plan the cable’s route carefully. For the red wire, ensure a route that will not crush or damage the wire in
any way.
9.4.1
Install DC Power Cable and Make Power and Ground Connections
1. Connect the control head’s DC Power Cable (Item 5 in Table 4-3) to the large 3-pin connector at the
rear of the control head. Visually align the key and gently push and turn the outer locking ring
clockwise until it stops. A click will be sensed to confirm proper mating.
2. At the back of the control head, form a cable service loop of at least six (6) inches, and tie and stow
the cable as necessary.
3. Route the cable’s red (positive power) wire through channels in the vehicle to the location of the Fuse
Distribution Rail Assembly near the V-TAC mobile radio. Remove interior panels, door kick panels,
etc. Protect the wire from possible chafing as necessary.
44
MM-011074-001
Do not share the control head’s fuse with any other device. Doing so can cause excess
current to flow through the fuse, causing it to blow unnecessarily.
4. At the Fuse Distribution Rail Assembly near the V-TAC, cut the red wire to the required length, strip
it, and connect it to the load-side of the Fuse Block that has the 5-amp ATC fuse. (This fuse was
installed during the rail assembly installation procedure presented in Section 8.2.2.) See the
illustration on page 38 and the following CAUTION.
CAUTION
The fuse for the control head is rated at 5 amperes. Installing the wrong fuse value
could lead to damage. Verify the control head is wired to the 5-amp (tan color) ATC
fuse!
5. At the back of the control head, locate a nearby section of vehicle chassis ground and strip this area of
any paint or dirt to expose a bare metal surface.
6. Cut the black wire of the control head’s DC Power Cable as short as possible, but long enough for a
service loop, then strip it and crimp a 3/8-inch ring terminal to it.
7. Drill a hole as necessary and screw this ring terminal to chassis ground. Use a self-threading screw or
other appropriate hardware to ensure a reliable metal-to-metal contact.
9.4.2
Connect DC Power Cable’s White Wire
A review of the information presented in Section 8.1 (page 32) may be beneficial at this time. As
required per the chosen power-up configuration, connect the white wire by following one of the
three procedures presented in the respective sub-section that follows. The control head’s DC Power
Cable and associated fuse and wire terminal devices are shown in Figure 9-8.
Only the control head’s white wire must be connected to the ignition or switched
power sense. When this vehicle line is asserted (i.e., power switched on), the control
head automatically powers-up the V-TAC via the CAN connection.
45
MM-011074-001
Figure 9-8: Connection of White Ignition Sense Wire Using Vehicle Fuse and T-Tap Kit
9.4.2.1
Control Head and V-TAC Turn on with Vehicle’s Ignition Switch/Key
With this wiring configuration, the control head and V-TAC automatically turn on and off with the
vehicle’s ignition switch/key. The white wire of the control head’s DC Power Cable is typically identified
as the “white ignition switch wire” or the “ignition sense wire.” In this configuration, the white wire
connects to a switched power source, typically identified as “Accessory” power, that switches on and off
with the vehicle’s ignition switch/key. When using this configuration, the CH-721 control head’s
on/off/volume control must be left in the on position for automatic power-up/down to function properly.
The white ignition sense wire must be connected to a fused power source that switches
from approximately zero volts to approximately +13.6 volts when the vehicle’s ignition
switch/key is turned from the OFF position to the ACCESSORY and RUN positions.
Use of a switched power source that is subject to voltage changes as a result of other
actions, such as opening a vehicle door, may result in undesirable V-TAC operation
and/or a degradation of V-TAC performance.
1. Locate the switched ignition or “Accessory” power wire (typically at or near the vehicle’s fuse block
or in a vehicle wiring harness) that will be used for the switched ignition power source. It may be
necessary to consult the vehicle manufacturer’s wiring diagram.
2. Route the white wire of the control head’s DC Power Cable from the back of the head to an area near
the switched ignition power source. At the back of the head, be sure to maintain a cable service loop
of at least six (6) inches.
3. Cut a short section (6 to 8 inches) off the end of the white wire and strip each end of this short wire.
46
MM-011074-001
4. From the Vehicle Fuse and T-Tap Kit (Item 7 in Table 4-3), locate the male-tab quick-connect
terminal and crimp it to one end the short wire. Refer to the respective wiring diagram at the end of
this manual.
5. From the same kit, locate the ATM fuse holder and crimp it to the other end of the short wire. The
holder has built-in crimpable joints.
6. Cut the excess length from the white wire of the control head’s power cable, strip it, and crimp it to
the other side of the ATM fuse holder.
7. Pull enough of the switched ignition source wire out of the vehicle’s wiring harness so one of the
T-tap quick-disconnect terminals may be attached to it.
8. Two T-tap quick-disconnect terminals are included in the kit. Based on the gauge of wire, select the
proper terminal size: Red is for 22 to 18-AWG wire and blue is for 18 to 14-AWG wire.
9. Attach the selected T-tap quick-disconnect terminal by fitting the wire into its wire groove and
snapping the two halves together with a pair of pliers as shown in Figure 9-9.
Diagram Courtesy of 3M Corp.
Figure 9-9: Attaching T-Tap Quick-Disconnect Terminals
10. Push the male-tab quick-disconnect terminal into the T-tap quick-disconnect terminal’s inlet until it is
fully engaged.
11. Install the 2-amp ATM fuse into the fuse holder. It is recommended that a piece of electrical tape be
wrapped around the fuse connection to keep the fuse from being jostled out of the holder.
12. Tie and stow these wires as necessary so they remain out of the way of casual contact and wire chafe
is avoided.
47
MM-011074-001
9.4.2.2
Control Head and V-TAC Turn On with a Manual Switch
With this wiring configuration, the control head and V-TAC are manually turned on and off via an on/off
switch mounted separately from the control head and V-TAC, not through the vehicle’s ignition
switch/key. This configuration is used when, for example, the V-TAC must remain on even when the
ignition key must be removed from the vehicle and a separate on/off switch is acceptable. In this
configuration, the white wire connects to a switched power source such as a toggle switch mounted on the
vehicle’s dash. When using this configuration, the CH-721 control head’s on/off/volume control must be
left in the on position for automatic power-up/down to function properly.
1. Route the white wire of the control head’s DC Power Cable from the back of the unit to an area near
the on/off switch’s location. At the back of the control head, be sure to maintain a cable service loop
of at least six (6) inches.
2. Cut a short section (6 to 8 inches) off the end of the white wire and strip the ends.
3. For a new on/off switch (not supplied):
(a) Tap a wire off non-switched battery power from the vehicle’s fuse box with an 18-AWG wire.
(Use wire remaining from the power cable, if available.) Keep wiring as short as possible and use
approved wiring methods. Use techniques presented in Section 9.4.2.1 as a reference.
(b) Strip and crimp this wire tap to one side of the ATM fuse holder. This holder is included with
Vehicle Fuse and T-Tap Kit, item 7 in Table 4-3. It has built-in crimpable joints.
(c) Crimp the short wire to the other side of the ATM fuse holder and connect the other end of this
wire to the common terminal of the manual switch.
(d) Connect the white wire of the power cable to the load (switched) side of the manual switch.
For an existing switch:
(a) Crimp the short wire to one side of the ATM fuse holder and connect the other end to the load
(switched) side of the manual switch.
(b) Crimp the white wire of the power cable to the other side of the ATM fuse holder.
4. Install the 2-amp ATM fuse into the fuse holder. It is recommended that a piece of electrical tape be
wrapped around the fuse connection to keep the fuse from being jostled out of the holder.
5. Tie and stow these wires as necessary so they remain out of the way of casual contact and wire chafe
is avoided.
6. Label this power switch accordingly. For example: “RADIO ON/OFF.”
9.4.2.3
Control Head and V-TAC Are “Hot Wired”
In the “hot-wired” configuration, the control head and V-TAC are turned on and off only by the control
head’s on/off/volume control located on the front panel of the control head. In this configuration, the
control head’s white wire must be connected to unswitched and fused 12-volt vehicle power. Follow the
procedure presented in Section 9.4.2.1, except connect the white wire to unswitched battery power
instead of switched (“Accessory”) power.

10 MICROPHONE ATTACHMENT
There are several versions of microphones available for use with the M7200 V-TAC mobile radio. Each
has a 17-pin flush-mount type connector that mates with the mic connector on the front panel of the
control head. The mic’s connector includes a captive thumbscrew that secures it to the mic connector on
the front panel of the control head. A microphone clip is included with each microphone. The V-TAC can
be configured to provide a monitor function when the microphone is cradled in the clip. Connect the mic
to the control head and install the clip as follows:
1. As illustrated in Figure 10-1, grasp the mic’s connector with a thumb and index finger on the sides of
the connector just adjacent to the thumbscrew.
2. Position the connector in front of the control head’s mic connector so the mic cable’s stain relief is
hanging down and out at an approximate 45-degree angle.
3. Mate the two connectors by pressing them fully together. Do not apply any force to the thumbscrew
when mating the connectors.
4. Tighten the thumbscrew finger-tight. Do not use a screwdriver to tighten it.
5. Using the microphone clip as a template, drill mounting holes in the surface of the selected location.
6. Attach the microphone clip to the mounting surface using self-threading screws. Select a location that
has clearance for the mic when it is clipped to the clip.
7. The microphone clip must be grounded to the vehicle’s chassis. If not mounted to a grounded metal
surface, complete this requirement by adding a jumper wire attached from chassis ground to the clip.
8. Clip the microphone to the clip.
As illustrated, do not apply any
force to the thumbscrew when
mating the mic connectors.

11 SPEAKER INSTALLATION
Select a location for the speaker that will allow for proper listening range with a moderate volume setting.
Total speaker cable length (of both cables) is approximately five (5) feet. Therefore, to include service
loops in the cables, the speaker must be mounted within approximately 4.5 feet of the control head.
1. Install the speaker (Item 8 in Table 4-3) using the hardware and mounting bracket supplied with it.
Also refer to the instructions included in the speaker for additional mechanical installation
information.
2. Route the speaker’s cable to the rear of the control head.
3. Mate the Speaker Cable (Item 9 in Table 4-3) to the 2-pin connector at the rear of the control head by
visually aligning the ¾-moon-shaped keys of the connectors, and then pushing and turning the outer
locking ring of the cable connector clockwise until it stops. A mild click will be sensed to confirm
proper mating.
4. Connect the speaker’s 2-pin plastic connector to the respective mating connector on the Speaker
Cable.
5. Route the cables out of the way of casual contact, and tie and stow as necessary.

12 V-TAC EXTENDED COVERAGE INSTALLATION
12.1 GENERAL INFORMATION
The V-TAC supports two Extended Coverage modes: Extended Coverage for individual users (display
reads “XCOV”) and Extended Coverage for talk groups (display reads “XCOV-TG”). Extended Coverage
adds the V-TAC’s “bridging” (vehicular repeat) functionality for accessing the OpenSky radio network
using connected portable radios. Each portable radio connected to the V-TAC using Extended Coverage
is considered a “client” on the V-TAC. Extended Coverage benefits (permitted) portable radio users since
it allows them to get network connectivity using the V-TAC’s higher transmit output power and better
antenna system. In addition, dispatchers can communicate with portable radio users (the clients)
connected to the V-TAC, and logging recorders can record their tactical communications.
With the XCOV mode, up to eight (8) client radios can connect to the V-TAC. These radios can operate
with all standard radio functions, including selective calling and mobile data.
Using the XCOV-TG mode, up to thirty (30) client radios can connect to the V-TAC. XCOV-TG is
designed to support a large number of client radios in a tactical scenario. However, unlike XCOV, radios
connected to using XCOV-TG are limited to communicating only on the XCOV-TG talk group and
emergency communications. Advanced features such as selective calling and mobile data operations are
not available to the XCOV-TG connected clients.
For complete details on the V-TAC’s various operating modes, refer to the Operator’s
Manual (publication number listed in Section 3.3).
In most cases, the Mobile-Only operating mode of the V-TAC (control head displays “Mobile”) is desired
when the vehicle is in motion. However, an Extended Coverage operating mode is desired when the
vehicle is stationary and the tactical situation warrants a V-TAC operating mode. Typically, an Extended
Coverage mode is utilized after the vehicle’s operator has exited the vehicle with a portable radio unit and
the portable unit requires the V-TAC’s “bridging” functionality to access the OpenSky radio network.
A four-beep high-medium-high-medium tone sequence sounds when the V-TAC enters an Extended
Coverage mode. Also, for ten (10) seconds, the Control Head’s display flashes “XCOV” for the Extended
Coverage for individual users mode, and “XCOV-TG” for the Extended Coverage for talk groups mode.
When in the Mobile-Only operating mode, neither indication is displayed.
Operating the V-TAC in an Extended Coverage mode when the vehicle is in motion can have serious
consequences to system operation and performance and is therefore not desired. This undesirable
condition is sometimes referred to as a “rolling V-TAC.” Proper connection to the V-TAC’s motion sense
input and appropriate radio software configurations can prevent the “rolling V-TAC” condition.
M/A-COM recommends connecting the V-TAC’s motion sense input to an automatic motion sensor
switch or a dash-mounted toggle switch, neither of which are supplied. An operating mode can also be
manually selected via the V-TAC’s “Vmode Menu” (V-TAC mode menu).
12.2 SOFTWARE CONFIGURATION AND WIRING
12.2.1
Inverting Interpretation of V-TAC’s Motion Sense Input Logic State with
“XEVENT” Command
As shown in Table 12-1, the “XEVENT” command allows inversion of how the V-TAC interprets the
condition of the V-TAC’s motion sense input. This allows inversion of the sense signal via software, thus
51
MM-011074-001
preventing the need of an external inverter circuit for the V-TAC’s motion sense input. This command
can be entered manually via the V-TAC’s serial port or the over-the-air interface using the following
syntax:
at@vtac-xevent N (where N = 0 or 1; see Table 12-1)
For information on entering commands via the V-TAC’s serial port, refer to Table 12-2 on page 53. Also
see Figure 16-1 on page 61 for required cable connections between a Personal Computer (PC) and the
V-TAC’s serial port.

There is no factory default “XEVENT” command setting. The value of “XEVENT”
must be defined as part of the personality profile loaded prior to installation. Not setting
a defined value will result in an arbitrary (random) setting. However, especially whereas
details of the installation may not be known until the installation has commenced, the
setting of “XEVENT” can occur locally through the V-TAC’s serial port at any time.
The best time for doing so is during the antenna PERFORMANCE TESTS procedures
presented later in this manual (subsections 16.3 and/or 16.4). It can also be done
remotely over-the-air after the antenna test procedures are completed.
Connecting the V-TAC’s motion sense input to a dash-mounted, manually controlled, 2-position switch is
highly recommended. Although manual intervention is required for turning XCOV mode on and off,
manually switching the mode prevents the V-TAC from entering XCOV mode unnecessarily.
For manual switching, use a single-pole double-throw (SPDT) type. This switch is not supplied with the
V-TAC. It should be wired so the V-TAC’s motion sense input switches between +12 Vdc and vehicle
ground (0 Vdc). Attach the V-TAC’s motion sense input to the switch’s pole/common terminal (usually
the center-most terminal), connect one of the poles to +12 Vdc raw battery voltage, and connect the other
pole to vehicle ground. For the +12 Vdc connection, fuse it using the ATM fuse holder and fuse supplied
in the Fuse Kit. Use excess wire from the DC power cable or use #18-AWG wire (not supplied) to make
the connections. Keep wiring as short as possible and use approved wiring methods. Place a placard or
label by the switch accordingly. For example: “V-TAC Extended Coverage ON/OFF.”
If the V-TAC’s motion sense input will be connected to a new (not supplied) or an existing automatic
motion sensor switch within the vehicle, refer to the installation instructions provided with the switch or
the vehicle manufacturer’s wiring diagram for specific wiring information. In this case, placing a
placard/label on the vehicle’s dash near the Control Head is recommended. For example: “V-TAC
Extended Coverage Operating Mode is DISABLED when vehicle is in motion.”
52
MM-011074-001
CAUTION
12.2.2
Connecting the V-TAC’s motion sense input to a vehicle switching signal such as one
from a parking brake or gear indication sensor switch or to another vehicle signal not
specifically designed for motion sensing may degrade the reliability of the vehicle’s
wiring system or even lead to a failure of a vehicle safety system such as anti-lock
brakes. Therefore, a connection of this type is not recommended.
Setting Default Extended Coverage Mode with “CMODE” Command
The “CMODE” command can be utilized to set the V-TAC’s default Extended Coverage mode. Like the
XEVENT command described in the previous section, this command can be entered manually via the
V-TAC’s serial port or via the over-the-air interface as follows:
at@vtac-cmode N (where N = 0 for XCOV mode, or 1 for XCOV-TG mode)
Refer to the PERFORMANCE TESTS subsections 16.3 and/or 16.4 for more information on entering
commands via the V-TAC’s serial port.

13 OPTIONAL CABLES
13.1 FULL-DATA I/O OPTION CABLE
The Full-Data I/O Option Cable 1000022242-0001 connects to the V-TAC’s 44-pin I/O cable connector.
It breaks out into three (3) separate D-subminiature 9-pin (DB-9) type connectors. It also has blunt-end
wires (i.e., not stripped or terminated with a connector) for optional/miscellaneous connections. This
combination allows straightforward access to all external I/O connections provided by the V-TAC. It also
helps speed V-TAC removal and re-installation time when required. This cable is shown in Figure 13-1.
When connected, each DB-9 connector of the Full-Data I/O Option Cable is a TIA/EIA-232 serial data
interface port for the V-TAC. The connector labeled “SERIAL” is the V-TAC’s serial programming port.
The connector labeled “MODEM” supports the RF modem function that the V-TAC can provide. The
connector labeled “GPS” provides NMEA-formatted GPS serial data connections for the external
computer processing the NMEA-formatted GPS data received by the V-TAC’s internal GPS receiver.
This optional cable adapts the V-TAC’s 44-pin I/O cable connector to standard 9-pin serial computer
cables, or alternatively, it can be plugged directly to a computer’s (or mobile data terminal’s) serial port
connector.
The blunt-end wires of the Full-Data I/O Option Cable provide connections for the following: (2) vehicle
signal inputs, (2) TTL logic level inputs, (2) open-collector logic outputs, and a baseband audio in/out
with PTT input and activate output. Table 13-1 shows the wiring of the Full-Data I/O Option Cable.

14 GPS NMEA-FORMATTED SERIAL DATA
CONNECTION
To obtain GPS NMEA-formatted serial data from the M7200 V-TAC mobile radio, use of the Full-Data
I/O Option Cable 1000022242-0001 is recommended. Follow this procedure to complete the GPS
NMEA-formatted serial data connections when using this recommended cable:
1. Connect the Full-Data I/O Option Cable’s 44-pin male connector to the V-TAC’s 44-pin female
connector. Tighten the two jackscrews with a small flathead screwdriver. Do not over-tighten.
2. Connect the cable’s DB-9 female connector labeled “GPS” to the computer’s serial port DB-9 male
connector — either directly or via an optional serial cable (MAMROS0055 or equivalent). Tighten
the screws firmly and then route the cabling as required.
3. Follow the manufacturer’s instructions on processing the NMEA-formatted GPS data from the
V-TAC.
If the Full-Data I/O Option Cable is not available, a 3-wire serial cable can be fieldfabricated. On the V-TAC end, this cable must interface to the three GPS-related signals
of the V-TAC’s 44-pin I/O Cable connector (pins 4, 20 and 34). See Table 13-1 for
additional information.
Industry software to process GPS information through this interface is not supported by
M/A-COM.
57
MM-011074-001
15 INITIAL POWER-UP TEST
1. At the installation’s main ATC fuse holder located near the vehicle battery, open the fuse holder’s cap
and install the 30-amp ATC fuse. This fuse is a part of the Fuse Distribution Rail Kit (a part of Item 2
in Table 4-1). Push the cap back onto the holder until the plastic tab snaps into place.
2. Optionally, fasten the cap to the wheel well or other vehicle surface via the hole in the cap’s mounting
tab and a self-threading screw (not supplied).
CAUTION
The installation’s main fuse is a 30-ampere ATC fuse. Installing the wrong fuse value
could lead to improper operation and/or damage. Verify the ATC fuse supplying power
to the Fuse Distribution Rail Assembly has the correct rating! The color of a 30-amp
ATC fuse is green.
3. Carefully reconnect the vehicle’s battery ground cable.
4. If the control head is not already powered up, do so by rotating its on/off/volume control clockwise
out of the detent position.
5. Verify the control head has powered-up by observing its display. If the display is not lit, refer to
Section 8.1 as necessary.
Unlike many mobile radio products, the V-TAC powers-up to the state of last control.
As long as the software configuration parameters have been loaded, successful installation is almost
immediately realized:
•
After a short boot-up sequence, the control head displays login information and/or a talk group.
•
If no errors are displayed, the installation is most-likely properly wired.
•
If an error is displayed, recheck all cable connections, verify all fuses are properly installed, and
verify battery power is getting to the two Fuse Blocks. If problems persist, contact M/A-COM’s
Technical Assistance Center (see page 18).
•
Consult the Operator’s Manual for operational information. Refer to Section 3.3 on page 17 as
necessary.
Refer to the following section for performance test information.
58
MM-011074-001
16 PERFORMANCE TESTS
This section includes procedures to verify the performance of the installation’s mobile antenna system.
Tests require a peak-power reading wattmeter to measure RF power. There are three procedures in this
section:
•
Changing Operating Mode for Tests
•
Testing by Transmitting into a Dummy Load (50-Ohm RF Terminator)
•
Testing by Transmitting into the Mobile Antenna
CAUTION
The accuracy of test results depends upon a DC power source in the range of 13.8 to
16 volts dc, with a current capacity of greater than 8 amps. Make sure the vehicle’s
battery is fully charged by running the engine for a few minutes before the test, and
keep the engine running during the test procedures. Abide by the following
WARNING! Alternatively, instead of running the vehicle’s engine for an extended
period of time, a 12-volt vehicle battery charger with a current capacity of at least
15 amps can be connected to the vehicle’s battery. If using a battery charger, observe
polarity when making the connections to the battery.
If the vehicle’s engine must remain running, the vehicle location should be well
ventilated so exhaust fumes from the engine do not cause harm!
CAUTION
If a vehicle equipped with this V-TAC mobile radio requires jump-starting, the radio
installation’s main ATC fuse should be removed from the holder prior to jumpstarting. Doing so will prevent damage to the V-TAC.
Prior to installation, the V-TAC’s VRM and VRB transmit RF output power levels
should be configured appropriately. The wide range of power levels indicated in the
following procedures takes into account such things as: customer’s requirements;
measurement errors, especially to include uncalibrated equipment; cabling losses; and
voltage and temperature variations. By no means should the result from Performance
Testing in this section be construed as the exact value of power level outputs from the
V-TAC, as values are set and more accurately measured in the factory. The values
obtained in these test procedures determine a successful installation only.
16.1 CHANGING OPERATING MODE FOR TESTS
The V-TAC must be operating in the OpenSky Trunking Protocol (OTP) mode during the performance
test procedures presented in this section:
16.1.1
Switching to OTP Mode
1. If necessary, apply power to the V-TAC and turn it on.
2. Rotate the Group Selection Control until Mode Menu appears in the middle line of the display.
Refer to Figure 9-1 and/or Figure 9-2 on page 39 as necessary.
59
MM-011074-001
3. Toggle the Ramp Control until OTP (or M: NM for mode = normal) appears in the top line of the
display.
4. Confirm the OTP selection by pressing the MENU button, then toggling the Ramp Control once (to
select Y for Yes), followed by pressing the MENU button again. The V-TAC will reboot and enter
OTP mode as indicated by the display.

5. Position the wattmeter’s slug to measure forward RF output power. Rotate it as necessary. The arrow
on the face of the slug must point away from the V-TAC and towards the dummy load for forward
power measurements.
6. Set the wattmeter to measure peak RF power.
7. Key the V-TAC transmitter via the microphone’s PTT button.
8. Compare the wattmeter’s reading with the target RF output power range of 8 – 15 watts. As stated in
the last NOTE on page 59, this wide power level range takes into account errors caused by cable loss,
voltage variations, etc.

Transmit only for as long as needed to take the measurement, then immediately
disable the transmission.
9. If the wattmeter reading is within the range, record the measured value in the appropriate space on
the data collection form near the end of this manual (page 64).
If the wattmeter reading is outside the range, verify the V-TAC’s power supply voltage (i.e.,
battery voltage) is within the specified range, recheck all connections and measure the RF output
power again. If this fails to produce a reading within the range, replace it and repeat this procedure. If
problems persist, contact M/A-COM’s Technical Assistance Center (see page 18).
16.4 TRANSMITTING INTO THE MOBILE ANTENNA
1. Connect the antenna cable from the vehicle-mounted 700/800 MHz antenna to the wattmeter as
shown in Figure 16-1.
2. If not already, turn the V-TAC on and set it to OTP mode. Refer to Section 16.1 as necessary.
3. Set the V-TAC to a test talk group, if available.
It is recommended that a test talk group be allocated for this testing. Otherwise,
interference with other radio users in the system may occur. Also, during
transmissions, always observe the RF exposure-related safety information
presented in Section 1.2 of this manual (begins on page 6).
A peak-power reading RF wattmeter equivalent to the wattmeter specified in Table
16-1 must be used. Do not use an average or RMS-responding wattmeter.
4. Position the wattmeter’s slug to measure forward RF output power. Rotate it as necessary. The arrow
on the face of the slug must point away from the V-TAC and towards the antenna for forward power
measurements.
5. Set the wattmeter to measure peak RF power.
6. Key the V-TAC transmitter via the microphone’s PTT button.
7. Compare the wattmeter reading with the target RF output power range of 8 – 15 watts.
Transmit only for as long as needed to take the measurement, then immediately
disable the transmission.
8. If the wattmeter reading is within the range, record the value in the appropriate space on the data
collection form near the end of this manual (page 64).
If the wattmeter reading is outside the range, verify the V-TAC’s power supply voltage (i.e.,
battery voltage) is within the specified range, recheck all connections, and measure the forward power
again. If this fails to produce a reading within the range, check all cabling and connections, and repeat
the testing procedure to this point. In the event the wattmeter reading still falls outside the range,
replace the antenna, make sure all connections are seated firmly, and repeat the testing procedure. If
problems persist, contact M/A-COM’s Technical Assistance Center (see page 18).

MM-011074-001
9. Position the wattmeter’s slug to measure reverse (reflected) RF power from the antenna. The arrow
on the face of the slug must point away from the antenna and towards the V-TAC to measure reverse
power.
10. Verify the wattmeter is still set to measure peak RF power.
11. Key the V-TAC’s transmitter via the microphone’s PTT button.
12. Compare the wattmeter reading with the RF power output range of 2 watts or less.
Transmit only for as long as needed to take the measurement, then immediately disable
the transmission.
13. If the wattmeter reading is within the range, record the value in the appropriate space on the data
collection form near the end of this manual (page 64).
If the wattmeter reading is outside the range, make sure the antenna is consistent with the specified
frequency range of the V-TAC. Recheck all antenna connections, and measure the reverse power
again. If this fails to produce a reading within the range, replace the antenna and repeat the entire
antenna test procedure. Any value exceeding the maximum allowable reflected power value will
result in a diminished RF output signal. If problems persist, contact M/A-COM’s Technical
Assistance Center (see page 18).
14. Disconnect the coaxial cable jumper and wattmeter.
15. Permanently connect the cable from the vehicle-mounted 700/800 MHz antenna to the V-TAC’s
antenna cable by mating the two TNC connectors together. Use two pairs of slip-jaw pliers to gently
tighten this connection. Do not over tighten and do not twist either cable.
To prevent RF leakage and ensure peak performance, make sure the RF connectors are
tight, but do not over tighten so connector damage will not occur.
Improper installation of the RF cables may lead not only to poor V-TAC
performance but also to harmful exposure to RF electromagnetic energy.
Testing is complete. The V-TAC is now ready for normal communications.

17 COMPLETE THE INSTALLATION
Double-check the following items before considering the installation completed:
•
Verify all newly installed mechanical hardware is mounted securely and all respective mounting
hardware is tight.
•
Verify all electrical interconnections are connected properly and the associated connector attachment
hardware is tight. Pay special attention to all RF antenna cables!
•
Verify all related fuses are correctly installed and properly rated.
•
Verify all electrical cables and wiring are tied, stowed, and protected so they are out of the way of
casual contact, away from sources of extreme heat, and wire chafing cannot occur. Pay special
attention to all RF antenna cables!
•
To prevent fumes from entering the vehicle’s passenger compartment, seal the hole/grommet/wire
combination at the firewall with a silicon-based sealer.
•
Verify all vehicle components are properly reinstalled such as kick panels, headliners, and seats.
•
If the installation includes a separately-mounted on/off power switch for manually turning the V-TAC
(and possibly others systems) on and off, verify it is labelled accordingly. For example: “Radio
ON/OFF.”
•
Remove all tools and unused hardware from the vehicle.
•
Verify the test performance data has been recorded on the data collection form shown in this manual.
