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.

NOTE

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.
http://www.fcc.gov/oet/rfsafety/rf-faqs.html
http://www.osha.gov./SLTC/radiofrequencyradiation/index.html

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.

MM23016

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)

•

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.

MM23016

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.

MM23016

PRODUCT DESCRIPTION
The M7200 mobile 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:

•

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.

•

An optional intercom function is available between control units. (Audio will be broadcast to ALL
connected control heads.)

MM23016

5.2

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.

MM23016

OPENSKY OPERATION

6.1

CH721 FRONT PANEL COMPONENTS
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.

MM23016
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.

6.2

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.

MM23016
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.

MM23016

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.

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.
Press the  button repeatedly 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.

6.10.2 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).

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 KEYPAD COMMANDS (SYSTEM MODEL CONTROL HEAD)
To perform a command from the keypad, press the * key followed by one of the pre-set function keys as
follows:
Log-off command: *0## (logs the user off the system). See page 17 for additional information.
Log-in command: *1 # ## (required for encryption). See page 16 for
additional information.
*4 Enter Scene of Incident Mode (SOI) on specified channel.
*7 Initiate Selective Alert command: *7#[Choose Message]#. See page 31 for
additional information.
*8 Radio-to-Radio Call command: Selective call number # (PTT to dial).

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.

MM23016

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.
to scroll through the available list of talk groups in the active profile. This list is

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
2. Use
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.

MM23016
6.18.1 Enabling Stealth Mode
1. Using

, 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. For
example, pressing the  button on the front panel will 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.
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:

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.
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.

MM23016
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.

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.

MM23016
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.
2. Use
to scroll through the list of talk groups, if any, until the desired talk group for lock out
appears in the top line of the display.
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
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.
to scroll through the list of talk groups, if any, until the talk group desired for unlocking
2. Use
appears in the top line of the display. A less-than symbol (“<”) appears next to the name of a talk
group that is currently locked out.
3. Press the MENU button to unlock the talk group. The less-than symbol (“<”) next to the name of the
talk group disappears. The dwell display appears as soon as the radio acknowledges the selection.

6.24.3 Caution Regarding Profile Changes
A talk group’s lock out status does not survive a change of profile. If after locking out talk groups in the
current profile and then selecting a new profile, all talk groups that were previously locked are
automatically unlocked.
Compare options before changing to another profile. If the user’s goal can be achieved by temporarily
assigning priority talk group status to a talk group, it could be possible to avoid having to lock out the
same talk groups again in a new profile.

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 6-5, 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
display.

until “SpeedDial” appears in the bottom line of the

2. Using
, scroll through the pre-programmed speed-dial numbers until the desired number
appears in the display.
3. Press and release the PTT button to ring the other user.
a. The ring tone is sounded.

MM23016
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 6-6 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.

1. Display the message.
2. Delete the message by pressing the MENU button.
3. Confirm the deletion by pressing the MENU button again.

6.27.3 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

MM23016
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:
•

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.

MM23016
•

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.

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.

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.

For an emergency alert declaration, “EMERG ALERT” indicates in the bottom line of the
display.

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.

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.

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.

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

MM23016
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 28 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.

6.29.5 Dismissing an Emergency Call
To ignore an emergency call declared by another radio user, dismiss it as follows:
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.

MM23016

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 Network Administration Server (NAS) 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 NAS. 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.
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.
NOTE

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

MM23016
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.

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:

MM23016
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]
