2 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.
CAUTION
Changes or modifications not expressly approved by M/A-COM, Inc. could void the user's
authority to operate the equipment.
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. M5300 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. M5300 two-way radio has an RF exposure product label. Also, your M5300 Installation and
Operator’s Manuals include information and operating instructions required to control your RF exposure
and to satisfy compliance requirements.

3 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.
• Interference to Vehicular Electronics Systems – Electronic fuel injection systems, electronic anti-
skid 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.
3.2 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.
10
MM-012125-001
4 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 M5300 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.

5 PRODUCT DESCRIPTION
Designed to meet the critical demands of utility and public service users, the M5300 mobile provides the
latest in digital radio technology. The M5300 is capable of supporting multiple operating modes,
including OpenSky® digital operation, EDACS® or ProVoice trunked modes, and conventional analog
mode.
The M5300 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 M5300 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 M5300 is constructed with an
industry-standard RS-232 interface serial port for connecting an optional laptop PC.
A PC, not included with the M5300, provides network connectivity through the standard serial
(DCE-type) interface.
The M5300 has an integrated Global Positioning System (GPS) receiver. This allows the M5300 to fully
support the Automatic Vehicular Locator (AVL) for fleet management and dispatch applications.
The OpenSky M5300 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.)
5.2 INTERCOM OPERATION
The intercom option, a licensed option, allows the M5300 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.

MM-012125-001
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.
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 Section 9 if the keys have been remapped

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 M5300 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.

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.
User-selected radio settings and last-tuned channel information will be lost if power is
abruptly disconnected from the radio prior to executing the correct turn-off procedure.
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 (Figure 6-3). 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.

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
ICON DESCRIPTION
Indicates data registration.
Volume bars – indicates relative volume
level.
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/alias1, received talk group, and current channel name.
Press the ramp control to scroll through and view one of these second line options.
6.10 PERSONALITY
As illustrated in Figure 6-4, 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.
1 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 M5300 radio also provides audible Alert Tones or “beeps” to indicate the various operating
conditions (see Table 6-3).
Table 6-3: M5300 OpenSky Mode Alert Tones
NAME TONE DESCRIPTION
Call Queued one low tone/two high tones Call queued for processing.

MM-012125-001
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:
Table 6-5: Keypad Function Commands
*0 Log-off command: *0## (logs the user off the system). See page 16 for additional information.
*1 Log-in command: *1<User ID> # <Password> ## (required for encryption). See page 15 for
additional information.
*4 Enter Scene of Incident Mode (SOI) on specified channel.
Exit SOI Mode with *4#.
*7 Initiate Selective Alert command: *7<Target ID>#[Choose Message]#. See page 30 for
additional information.
*8 Radio-to-Radio Call command: Selective call number # (PTT to dial).
*9 Public Switched Telephone Network (PSTN) Call command: See page 32 for additional
information.
*32 Begin Manual Encryption command: *32<Pre-Determined Encryption Key >#
1 – 16 digit encryption key for 128 bit encryption; 17 – 32 digit encryption key for 256 bit
encryption. See page 36 for additional information.
*33 End Manual Encryption command.
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.
22
MM-012125-001
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 until “ProfileMenu” is displayed.
2. Use 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 to scroll through the available list of talk groups in the active profile. This list is
determined by the OpenSky network administrator.
Second Method:
From the dwell display, use the talk group selection knob or to scroll through the available list of
talk groups in the active profile.
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.
2. Use 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.
23
MM-012125-001
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.
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:
1. Use to cycle through the menu until the “Side Menu” appears in the bottom line of the
display.
2. Use to change to the desired level (Off, Low, Medium, and High). To turn side tones
completely off, use the “Off” setting.
6.20 CHANGE OPERATING MODE
1. Use to cycle through the menu until the “Mode Menu” appears in the bottom line of the
display.
2. Use to choose an available mode. Press MENU and confirm (Y/N) with and MENU
again.
3. Press the MENU button to confirm.
24
MM-012125-001
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 15
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:
1. Use to scroll through the menu until “Treble Menu” appears. The radio’s current treble level
setting indicates in the top line of the display. There are four levels available: low, medium, medium-
high 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.
25
MM-012125-001
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.
26
MM-012125-001
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.
2. Use to scroll through the list of talk groups, if any, until the talk group desired for unlocking
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.
• Changing the active profile removes any lockouts you have made.
• Turning off the radio removes any lockouts you have made.
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.
27

Follow this procedure to set talk groups in the current profile as the Priority 1 or Priority 2 talk group:
1. Use to scroll through the menu until “Priority1” or “Priority2” appears in the bottom line of
the display (Priority1 group has higher priority than the Priorty2 group. The talk group currently set
as the priority talk group appears in the top line of the display.
2. Use to select a new priority talk group.
3. Press the MENU button to set the newly selected talk group as the priority talk group.
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 pre-
programmed 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.
29
MM-012125-001
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 until “SpeedDial” appears in the bottom line of the
display.
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.
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 until deleted 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:

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
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 M5300 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 M5300 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
32
MM-012125-001
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 13.
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.
• 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.
33
MM-012125-001
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
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 27 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.
34
MM-012125-001
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
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.
2. Press until the talk group in the emergency state appears, as indicated by an asterisk (*)
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., M5300 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.
35
MM-012125-001
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 and is entered into the radio using the keypad. For 128 bit encryption, this key
is between 1 and 16 digits. For 256 bit encryption, this key is between 17 and 32 digits.
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.
CAUTION
Do not set a talk group for manual encryption if it has been set for encryption by the
network administration personnel.
Perform the following to transmit or receive manually encrypted calls:
1. Press *32 on the keypad.
2. Enter the key (1 – 16 digits for 128 bit encryption; 17 – 32 digits for 256 bit encryption).
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
36
MM-012125-001
• 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 re-
registration, 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]

1.2 RF ENERGY EXPOSURE AWARENESS AND CONTROL
INFORMATION FOR FCC OCCUPATIONAL USE REQUIREMENTS
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.
CAUTION
Changes or modifications not expressly approved by M/A-COM, Inc. could void the
user's authority to operate the equipment.
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
MM-012137-001
7
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. 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:
http://www.fcc.gov/oet/rfsafety/rf-faqs.html
http://www.osha.gov./SLTC/radiofrequencyradiation/index.html
1.2.1 Federal Communications Commission Regulations
Before it is marketed in the United States, the M5300 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 M5300 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 a standby mode.
The M5300 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. Based on the highest radiated RF power and with respect to
the cables supplied with the antennas, the distances listed in Table 1-1 are considered
as safe distances for controlled and uncontrolled environments for the listed antennas.

The information listed above provides the user with information needed to make him or her aware of a RF
exposure, and what to do to assure that this radio operates within the FCC exposure limits of this radio.
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 anti-
skid 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 by a seal 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 driver-
side and passenger-side front-impact airbags, some vehicles may also be equipped with side-impact
airbags. For occupant safety, verify the location of all airbags within the vehicle before installing the
radio equipment.
MM-012137-001
10
1.6 SAFE DRIVING RECOMMENDATIONS
The American Automobile Association (AAA) advocates the following key safe driving recommenda-
tions:
• 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.
1.7 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 M5300 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:
• 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.
• No changes or adjustments shall be made to the equipment except by an authorized or certified
electronics technician.
MM-012137-001
11
CAUTION
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.
1.8 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.

3 INTRODUCTION
3.1 GENERAL DESCRIPTION
The M5300 mobile radio is a high-performance half-duplex digital mobile radio. It can operate on
900 MHz OpenSky trunked radio networks using the OpenSky Trunking Protocol (OTP). Other future
radio operating modes include talk-around communications in accordance with the APCO Project 25
phase I standard, and conventional FM repeater-based and FM talk-around voice communications in
accordance with the TIA/EIA-603 conventional land-mobile radio standard.
The initial release of this radio only supports operations on 900 MHz OpenSky trunked
radio networks. Later releases of the radio will add other modes to support other
trunked radio networks, and conventional FM repeater-based and FM talk-around voice
communication modes.
The M5300 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 OTP mode, the radio’s 900 MHz RF transmit output power is rated at 12 watts. 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.
In the remote-mount configuration of the M5300, the control head is located near the radio operator’s
position and the radio is mounted remotely from the control head, typically in the vehicle’s trunk. The
remote-mount radio is shown in Figure 5-2 on page 22.
Control heads used with the M5300 radio include the CH-721 Scan and the CH-721 System model
control heads. See Figure 7-2 (page 33) through Figure 7-4. 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) functionality and easier operator system/group selection
control at the control head’s front panel.
The remote-mount M5300 radio 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. It is remotely
controlled by a control head(s) connected to it via 3-wire Controller Area Network (CAN) cables.
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 multiple control head installations, two or more control heads
are interconnected to the mobile radio in a series (“daisy-chain”) fashion via CAN link cables. Up to five
(5) control heads can be connected to a remote-mount M5300.
As shown in Figure 7-4 on page 34, the CH-721 Scan and System model control heads used in remote-
mount radio installations have several connectors located on the head’s 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.
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. In a remote-mount radio
installation, the control head(s) connected to the radio is also powered by the same DC power source, but
MM-012137-001
15
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.
The radio provides half-duplex voice and data communications. Voice communications are accomplished
via a “push-to-talk” (PTT) type microphone and a speaker connected to the control head.
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 off-
the-shelf applications. OpenSky employs User Datagram Protocol over Internet Protocol (UDP/IP) data
packet transfers, providing “plug and play” connectivity for data-type devices.
900 MHz operating bands of the radio include 896 to 901 MHz repeater input band (mobile transmit) and
the 935 to 940 MHz band used for repeater output and talk-around communications.
The radio has an optional 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 unit’s location and the radio transmits it to the radio network. The GPS antenna may be
integrated into the mobile transmit/receive antenna (i.e., a “combination” antenna) or it may be separate
from the mobile transmit/receive antenna.
The radio and control head exceed many tough environmental specifications included within military
standard MIL-STD-810F, the radio industry standard TIA/EIA-603, and the radio standard established by
the U.S. Forest Service.
An M5300 radio operating on an OpenSky radio network uses Time-Division Multiple-Access (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 M5300 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.
Speech compression electronic circuitry—be it AMBE or another type such as IMBE—is sometimes
referred to as “vocoding” circuitry for voice coding, or simply a “vocoder” circuit.
Future M5300 radio upgrades will also support radio operation on 800 MHz APCO Project 25 phase I
compliant Common Air Interface (P25 CAI) trunked radio networks, and operation in a talk-around mode
in accordance with the APCO Project 25 phase I standard. P25 radio systems utilize Improved Multi-
Band Excitation Plus (IMBE™) speech/data compression technology, also developed by Digital Voice
Systems, Inc.
This manual contains installation procedures for the M5300 mobile radio and the CH-721 control heads.
The 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.

5.3 LOCATING COMPONENTS
Plan the mounting locations of all components (radio, control head, antenna, and cables) and determine
the routes for all wiring and cables. Particularly consider the connection of the radio 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.
• For a remote-mount radio installation, the radio is typically located in the motor vehicle’s trunk, or
some other preferably unoccupied section in a vehicle, such as a fire truck’s equipment shelf, and the
control head is typically located under the vehicle’s dash panel. Radio and control head dimensions
are listed in Section 2.1 on page 12. As noted in that section, these dimensions do not include space
required at the rear of the radio and control head for cables. Several inches of clearance space is
required at the back of the control head, and at least six (6) inches is recommended at the back of the
radio. In addition, several inches of clearance space is required at each side of the radio for access to
the screws that secure the radio to its mounting bracket.
• When selecting a mounting location, verify sufficient clearance behind the radio can be maintained so
cables will not be stressed, crushed, twisted, or bent at severe angles. This also applies to the control
head in a remote-mount radio installation. Also, the front and sides of the units must have clearance
for air circulation, access to mounting screws, mounting hardware, etc.
• Verify the drilling of holes and the insertion of screws will not damage or interfere with any existing
vehicle components (for example, a fuel tank, fuel lines, the transmission housing, etc.), or any
existing vehicle wiring.
• For antenna location and installation-related information, refer to Section 6 that follows.
CAUTION
The radio must be kept out of direct sunlight and away from heat sources. Adequate
free-air ventilation must be provided to its rear fins. The radio will automatically
reduce its transmit RF output power when its ambient temperature exceeds
approximately +140° Fahrenheit (+60° Celsius).
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.

6 ANTENNA INSTALLATION
6.1 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 6-1 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 must be mounted in one of three possible locations on the vehicle as described in the following
subsections. Figure 6-1 shows the recommended locations and antenna part numbers for each location.
Also, see Table 4-2 for additional information. Always follow the antenna manufacturer’s instructions
when mounting an antenna.

6.1.1 Direct Center or Center-Rear of Rooftop
The center of the vehicle’s roof is the best location for a rooftop-mount antenna (location n in Figure
6-1). 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 (location o in Figure 6-1).
6.1.2 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 (location p in Figure
6-1). 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 treated
as custom and separately specified.
6.2 ANTENNA INSTALLATION PROCEDURE
An antenna must be installed before completing the radio installation.
6.2.1 Install and Connect the Mobile Antenna
Table 4-2 (page 18) and Figure 6-1 (page 24) list the mobile radio antennas available for use with the
radio. 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. The following
mobile antenna installation procedure is recommended:
1. Once the mounting location is selected, refer to the antenna manufacturer’s mounting and testing
instructions included with the antenna kit for installation guidance. Install the antenna in accordance
with these instructions. If necessary, contact M/A-COM’s Technical Assistance Center. See page 16
for TAC contact information. As noted in the previously presented WARNING, do not cut the
cable to a shorter length!
2. Route the cable from the antenna base to the location of where the radio will be installed. Remove
headliner panel, interior panels, etc., as necessary. The cable must be kept out of casual contact from
persons within the vehicle. Tie and stow it as necessary to protect it possible chafing.
3. If not already, attach the male TNC RF connector (supplied with antenna) to the mobile-end of the
antenna cable. Attach this connector to the cable in accordance with instructions supplied with
antenna and/or TNC connector. As noted in the previously presented WARNING, do not cut the
cable to a shorter length!
MM-012137-001
26
A unity-gain antenna is tuned for maximum performance (i.e., minimum reflection) per
the test procedures presented in Section 13. Other antennas used with the M5300 are
factory-tuned and therefore do not require tuning in the field.
4. The antenna cable is connected to the radio’s TNC receptacle-type (female) RF connector per a
procedure presented later in this manual. The cable and its TNC connector must be protected from
damage, dirt, and/or metal shavings which may be generated during the mechanical and electrical
installation of the radio. Temporarily tying the connector and cable-end within a small plastic bag is
recommended.
6.2.2 Install and Connect the GPS Antenna
(Required Only if Radio has GPS Receiver Option)
If the M5300 radio is equipped with the GPS receiver option, the GPS receiver requires connection to an
externally-mounted GPS antenna. The GPS antenna must be kept at least six (6) inches away from any
other antenna mounted on the vehicle and it must have at least six inches of surface ground plane beneath
it. The following antenna installation procedure is recommended:
An SMR/GPS combination (“combo”) antenna kit includes a GPS antenna built into
the base of the mobile antenna. Refer to Table 4-2 (page 18) and/or Figure 6-1 (page
24) for available combo antennas.
1. Once the mounting location is selected, refer to the antenna manufacturer’s mounting and testing
instructions for installation guidance. Install the antenna in accordance with these instructions. If
necessary, contact M/A-COM’s Technical Assistance Center. See page 16 for TAC contact
information. Do not attempt to alter the GPS antenna cable length; tie and stow excess cable as
necessary.
2. Route the cable from the antenna base to the location of where the radio will be installed. Remove
headliner panel, interior panels, etc., as necessary. The cable must be kept out of casual contact from
persons within the vehicle. Tie and stow it as necessary to protect it possible chafing.
3. The antenna cable is connected to the radio’s SMA receptacle-type (female) RF connector per a
procedure presented later in this manual. The cable and its (male) SMA connector must be protected
from damage, dirt, and/or metal shavings which may be generated during the mechanical and
electrical installation of the radio. Temporarily tying the connector and cable-end within a small
plastic bag is recommended.

7 REMOTE-MOUNT RADIO INSTALLATION
7.1 MOUNTING THE RADIO
This section provides details on mounting the mobile radio in the vehicle. 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 7.3 which begins on page 33.
As an assembled unit, the radio weighs approximately 8 pounds (3.63 kilograms). The preferred mounting
of the radio is on top of a firm, flat surface.
Mobile Radio Installation Kit MAHK-NZN7R (contents listed in Table 4-1 on page 17)
contains the most complete set of materials for installing the radio. 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 radio has the proper version of software
and verify it has been configured properly for customer usage.
CAUTION
Though generally mounted in a trunk or remote location, the radio 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 radio 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 radio and its mounting 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
Before drilling holes and/or installing mounting screws, verify these operations will not
damage or interfere with any existing vehicle component (the fuel tank, a fuel line, the
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.
7.1.1 Mounting Bracket Installation
Typically, the radio’s mounting bracket (a part of 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 and the gauge of deck’s sheet metal is high (16-guage minimum).
When selecting a mounting location for the radio, verify sufficient clearance can be maintained around
the radio for installation and service access. A minimum distance of four (4) inches is recommended at
MM-012137-001
28
the rear, left and right sides of the radio, and at least (2) inches of clearance is recommended at the front
of the radio.
As illustrated in Figure 7-1, the bracket is left-to-right symmetrical and the shortest portion of its side
rails are at the rear.

is recommended. Sheet metal screws should never be used. The bracket has four (4) available mounting
holes, and all four must be used to secure the bracket to its mounting surface.
The following mounting procedure is recommended:
1. Using the mounting bracket (part of item 1 in Table 4-1 on page 17) as a template, and/or the
dimensional information shown in Figure 7-1, mark and drill four (4) mounting holes into the
mounting surface as required per the type of hardware used. When the radio is installed in the bracket,
it will extend approximately one (1) inch past the front edge bracket, and at the rear, it will extend
approximately ½-inch past the rear edge of the bracket. This distance at the rear does not include
space required for cable connections at the rear of the radio. As previously stated, a clearance of least
four (4) inches at the rear of the radio is recommended.
2. Temporarily remove the bracket and deburr all of the newly drilled holes.
3. If necessary, apply an approved paint or rust-inhibitor at the holes in the mounting surface.
4. Set the bracket back into place, and verify front-to-back orientation.
5. Install and tighten the mounting screws/hardware.
6. Verify the bracket is firmly secured to the mounting surface. A secure mount prevents unreasonable
vibration, which could damage the radio and/or cause its cable connections to loosen.
7.1.2 Inserting the Radio into the Mounting Bracket
The radio should now be inserted into the bracket according to this procedure:
1. Lay the radio down into the mounting bracket with the front of the radio at the front of the mounting
bracket.
2. Attach the radio into the mounting bracket using the six (6) Torx® drive M5 x 10 mm stainless-steel
socket-head screws, and flat and lockwashers included with the Mounting Bracket Kit (item 1 in
Table 4-1). Tighten all six screws using a 4-millimeter hex key wrench until each lockwasher is fully
compressed and the radio is firm and flush in between the brackets.
3. 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 radio performance. An improperly
mounted radio may experience degradation in the quality of voice and data
communications.

7.2 RADIO DC POWER INSTALLATION
Refer to the wiring diagram at the end of this manual as necessary when performing wiring procedures
presented in this section. For specific information on wiring the control head’s power, see Section 7.3.4
on page 39.
7.2.1 Overview of On/Off Power Wiring Configurations
Radio on/off power control is accomplished by the control head, except in the case of a data-only radio
installation which has no control head. In a standard installation, when the control head is turned on, it
“wakes-up” the radio via data activity on the CAN link. The following power wiring configurations are
supported:
• Radio turns on and off automatically with vehicle’s ignition switch/key — This configuration
allows the on/off state of the vehicle’s ignition switch/key to control the on/off power state of the
radio. The white wire of the control head’s DC Power Cable is connected to a fused switched power
source, typically identified as vehicle “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 3 amperes.
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.
To fuse the white wire of the control head’s DC Power Cable, a waterproof (HFB type)
fuse holder and a 3-amp AGC fuse are included with the cable when it ships from the
factory.
• Radio turns on and off with a manual switch — This configuration is used when, for example, the
radio must remain on even when the ignition key must be removed from the vehicle and a separate
on/off switch is acceptable. The white wire of the control head’s DC Power Cable is connected to one
side of a manually-controlled switch, and the other side of this switch is connected to unswitched and
fused vehicle power. The required fuse rating is 3 amperes. 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.
• Radio turns on with control head’s on/off/volume control (“hot wired”) — This configuration
allows radio on/off power control only via the control head’s on/off/volume control. It may be desired
if, for example, the radio must remain on even when the ignition key must be removed from the
vehicle and a separate on/off switch is not desired and/or not acceptable. The white wire of the
control head’s DC Power Cable must be connected to unswitched and fused vehicle power. The
required fuse rating is 3 amperes.
In all of the above cases, both the radio’s main DC power input (red wire) and the control head’s main
DC power input must each be connected through an in-line fuse to unswitched vehicle DC power. The red
wire of the radio’s DC Power Cable must be connected to raw battery power (positive battery terminal)
via the supplied fuse. Likewise, the red wire of the control head’s DC Power Cable must also be
connected to unswitched vehicle DC power via another supplied fuse. The white ignition wire of the
radio’s DC Power Cable is only used for the data-only radio (i.e., no control head), and it is the only
means for turning its power on in the data-only radio installation.
7.2.2 DC Power Cable and Main Fuse Holder Installation
The radio’s DC Power Cable has a 3-pin connector, a 20-foot red wire (for the main power connection), a
20-foot white wire (only connected in a data-only radio installation), and a 4-foot black wire (for the
MM-012137-001
31
ground connection). It is supplied with waterproof fuse holders, AGC-type fuses, and non-insulated ring
terminals. The following installation procedures are recommended:
7.2.2.1 Black Wire Connection (Ground Wire)
1. Connect the radio’s DC Power Cable to the radio by mating its 3-pin connector to the radio’s 3-pin
power cable 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.
CAUTION
Do not confuse the radio’s DC Power Cable which has a 10-AWG red wire with the
control head’s DC Power Cable which has a 12-AWG red wire. The radio requires
much more DC operating current than the control head. Therefore, it requires the
larger wire size of 10-AWG. The part number of the radio’s DC Power Cable is
CA-012365.
2. Prepare to connect the cable’s black wire to vehicle ground by locating an area of vehicle metal
within approximately two (2) feet of the radio. This surface must have a solid and stable connection
to vehicle ground. If not, add grounding strap(s) as necessary.
3. Strip the area of any paint or dirt to expose a bare metal surface, approximately ¾-inch square.
4. Drill a hole in the approximate center of the bare metal surface, and deburr it. A ⅜-inch non-
insulated ring terminal is supplied with the cable to make this ground connection. Therefore, hole
diameter should be appropriate for the utilize grounding screw/bolt size and type used to connect the
ring terminal to the bare metal surface. This hardware is not supplied.
5. Cut the black wire to the required length plus some additional length for a service loop, then strip
insulation back approximately ¼-inch.
6. Crimp a ⅜-inch non-insulated ring terminal (supplied with the cable) to the end of the black wire.
7. Attach the ring terminal and black wire to the bare metal surface using a self-threading screw (not
supplied) or other appropriate hardware to ensure a reliable terminal-to-metal contact. Tighten
securely.
8. Apply an approved paint or rust-inhibitor over the remaining exposed bare metal surface, and around
the ring terminal.
7.2.2.2 Red Wire and Main Fuse Holder Connection (Radio’s Main Power Wire)
1. Continue installation of the DC Power Cable by routing its 20-foot 10-AWG red wire to the location
of the vehicle’s battery (or its main DC bus bar or stud). Route the wire through channels in the
vehicle to the location of the battery. Remove interior panels, door kick panels, etc., as necessary.
Protect the wire from possible chafing where necessary, and tie and stow it as necessary.
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.
MM-012137-001
32
CAUTION
Do not install any wiring or fuse holder over or in the near vicinity of the vehicle’s
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(s). This will prevent tools or other metallic
objects which come in contact with the battery’s positive terminal from shorting to
vehicle ground, causing sparks or even a fire or an explosion! When disconnecting
the negative cable(s), cover/insulate the positive post(s) if it is not already so a tool
cannot short between the posts.
Radio and control head fuses should not be installed until all wiring is complete.
This will prevent the radio from powering up prematurely and/or causing an in-
rush of current that could lead to shorting of the battery, sparks, or even fire.
2. Obtain one of the waterproof (HFB type) fuse holders included with the DC Power Cable.
3. Observe and follow the previously presented WARNING!
4. Cut the red wire to the required length for connection to the battery’s positive (+) battery terminal (or
the main DC bus bar or stud).
5. Prepare to splice the waterproof fuse holder into the red wire by cutting it again, at approximately
three (3) to six (6) inches from the end.
6. Strip all three (3) wire ends back approximately ⅜-inch, place a fuse holder shell on each wire, and
securely crimp a fuse holder terminal to each wire end. Before crimping, verify fuse holder shells are
oriented in the correct directions.
7. Do NOT install a fuse into the fuse holder at this time.
8. Crimp a ⅜-inch ring terminal to the short red wire. The terminal is included with the DC Power
Cable.
9. 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).
Most M5300 radio installations have one or more control heads connected to the radio. In
an installation of this type, the white wire of the radio’s DC Power Cable requires no
electrical connection. Rather than be cut from the cable, it is recommended that it be
routed up to the vehicle’s fuse box, coiled, labeled, and stowed for possible future use.
The white wire of the control head’s DC Power Cable is the radio installation’s ignition
sense input for on/off power control of both the control head and radio. Radio on/off
power control is accomplished by the control head. The control head “wakes-up” the radio
via data activity on the CAN link.
7.2.2.3 White Wire Connection (for a Data-Only Radio Installations Only)
In the case of a data-only radio installation (i.e., no control head connected to the radio), the white wire of
the radio’s DC Power Cable is used as the radio installation’s ignition sense input. Therefore, in this case,
it requires electrical connection to a fused switched power source. The following procedure is
recommended:
MM-012137-001
33
1. Route the 20-foot white wire of the radio’s DC Power Cable to the location of the vehicle’s switched
power source connection point, typically identified as “Accessory” power. Route the wire through
channels in the vehicle to the location of the battery. Remove interior panels, door kick panels, etc., as
necessary. Protect the wire from possible chafing where necessary, and tie and stow it as necessary.
2. Connect this white wire through a fuse to the switched power source in accordance with the
instructions presented within the respective subsection of Section 7.3.4.2 (page 40) for the control
head’s white wire. Follow Section 7.3.4.2.1 (page 40) if the vehicle’s ignition switch/key must
control the data-only radio’s on/off power. Follow Section 7.3.4.2.2 (page 40) if a manually-
controlled switch must control the data-only radio’s on/off power.
The “hot wired” wiring configuration (as depicted in Section 7.3.4.2.3) cannot be utilized
for the data-only radio, since this configuration does not employ the DC Power Cable’s
white wire.
CAUTION
When servicing the radio and/or control head, always manually turn all units off and then
pull the main power fuse in the engine compartment.
7.3 CONTROL HEAD INSTALLATION
7.3.1 General Information
The remote-mount M5300 mobile radio 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 7-2 and Figure 7-3 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 7-4 on page 34 illustrates the rear panel of the two control head models. Both models have
identical rear panels and rear panel connectors.

In a mobile installation, more than one control head can be connected to one mobile radio for multi-head
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 radio. Multi-head installations also provide
other benefits such as intercom functionality between different operator positions.
7.3.2 Control Head Mechanical Installation
7.3.2.1 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 20. 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.

Figure 7-6: Optional Control Head Mounting Pedestal (Part Number MACDOS0012)
7.3.2.2 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. As listed in Table 4-1 on page 17, this bracket is item 2 in the
Installation Kit.
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 hex-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.
7.3.2.3 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 7-6, 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.
7.3.3 Control Head-to-Radio CAN Cable Connections
7.3.3.1 General Information
A remote-mount radio installation requires a CAN cable between every two “CAN devices” and CAN
terminators on each end of the CAN link. The M5300 mobile radio is considered a CAN device, and each
CH-721 control head in the installation is also considered a CAN device. Figure 7-7 illustrates CAN cable
and CAN terminator connections for a single control head installation. Figure 7-8 illustrates this for a
multi-head 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 external CAN terminators, as depicted in
the following figures.
Figure 7-7: CAN Link Connections for a Single Control Head Installation
MM-012137-001
38
Figure 7-8: Typical CAN Link Connections for a Multi-Control Head Installation
Both the radio 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 22 shows the radio’s two CAN port connectors, which
are located near the center of the radio’s rear panel. Figure 7-4 on page 34 shows the two CAN port
connectors on the control head’s rear panel.
7.3.3.2 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 7-8 as necessary.
1. Mate a CAN Terminator (item 6 in Table 4-1 on page 17) onto either one of the two smaller 3-pin
CAN port connectors on the rear panel 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) to a rear panel connector,
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. Obtain a CAN Cable and mate it to the other CAN port connector on the rear panel of the CH-721.
Typically item 7 in Table 4-1 is utilized, a 30-foot CAN cable.
3. Route the cable through the vehicle’s interior wire/cable channeling to the radio. Remove interior
panels, door kick panels, etc., as necessary. Protect the cable from possible chafing as necessary.
MM-012137-001
39
4. Mate this other end of the cable to one of the two CAN port connectors on the rear panel of the radio.
5. Mate another CAN Terminator to the other CAN port connector on the rear panel of the radio. This
action makes the CAN termination at the radio-end of the CAN link.
6. Loop, tie and stow the excess cable as necessary, leaving a service loop at the back of the radio and at
the back of the control head.
7.3.4 Control Head Power Cable Installation
Plan the route of the control head’s DC Power Cable carefully. Do not route the cable where it will be
damaged by heat sources or by casual contact, and protect it from wire chafe per standard installation
methods. The following procedures are recommended:
7.3.4.1 Install DC Power Cable and Make Power and Ground Connections
1. Connect the control head’s DC Power Cable (item 4 in Table 4-1 on page 17) to the large 3-pin
connector at the rear of the 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, locate a nearby section of vehicle chassis ground and strip this area of
any paint or dirt to expose a bare metal surface.
3. Cut the black wire of the control head’s DC Power Cable to the required length, plus a service loop of
at least six (6) inches, then strip it and crimp a 3/8-inch ring terminal to it. Two ring terminals of this
type are included with the cable when it ships from the factory.
4. Drill a hole as necessary and attach this ring terminal to chassis ground. Use a self-threading screw or
other appropriate hardware to ensure a reliable metal-to-metal contact.
5. At the back of the control head, form a cable service loop, and tie and stow the cable as necessary.
6. For the positive 12-volt DC power source connection, route the cable’s red wire to the location of an
unswitched 12-volt DC power source. Remove interior panels, door kick panels, etc. Protect the wire
from possible chafing as necessary. This is the control head’s main DC power source.
7. Obtain one of the waterproof (HFB-type) fuse holders included with the control head’s DC Power
Cable.
8. Cut excess length from the red wire and splice the fuse holder into it, near the location of the
unswitched 12-volt DC power source connection point.
9. Using an appropriate electrical terminal, connect the red wire to the unswitched DC power source. A
3/8-inch ring terminal is included with the cable for this purpose, but another terminal type (not
supplied) may be used if required.
10. Obtain the 5-amp AGC-type fuse included with the cable, and install it into the fuse holder.
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.
CAUTION
The fuse for the control head’s red wire is rated at 5 amperes. The 3-amp fuse included
with the cable must not be used for fusing the control head’s main DC power. It fuses
the head’s white wire.
MM-012137-001
40
7.3.4.2 Connect DC Power Cable’s White Wire
A review of the information presented in Section 7.2.1 (page 30) 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.
7.3.4.2.1 Control Head and Radio Turn on with Vehicle’s Ignition Switch/Key
With this wiring configuration, the control head and radio automatically turn on and off with the vehicle’s
ignition switch/key. The white wire of the control head’s DC Power Cable is sometimes referred to as the
“white ignition switch wire” or the “ignition sense input 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 radio operation and/or
a degradation of radio performance.
1. Locate the vehicle’s switched ignition or “Accessory” power connection point that will be used for
the switched ignition 12-volt DC power source. This point is typically located at or near the vehicle’s
fuse panel. 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 the area near
this connection point. Protect the wire from possible chafing as necessary.
3. Obtain one of the waterproof (HFB-type) fuse holders included with the control head’s DC Power
Cable.
4. Cut excess length from the white wire and splice the fuse holder into it, near the location of the
connection point.
5. Using an appropriate electrical terminal, connect the white wire to the switched power connection
point. An open-barrel spade terminal is included with the cable for this purpose, but another type of
terminal (not supplied) may be used as required.
6. Obtain the 3-amp AGC-type fuse included with the cable, and install it into the fuse holder.
7. Tie and stow all wiring as necessary so it remains out of the way of casual contact and wire chafe is
avoided.
7.3.4.2.2 Control Head and Radio Turn On with a Manual Switch
With this wiring configuration, the control head and radio are manually turned on and off via an on/off
switch mounted separately from the control head and radio, not through the vehicle’s ignition switch/key.
This configuration is used when, for example, the radio must remain on even when the ignition key must
be removed from the vehicle and a separate on/off switch is acceptable and/or required. In this
configuration, the white wire connects to a fused switched power source such as that provided by a toggle
switch mounted on the vehicle’s dash panel. 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 head to an area near
the location of the panel-mounted on/off switch. Protect the wire from possible chafing as necessary.
MM-012137-001
41
2. Cut a short section (6 to 8 inches) off the end of the white wire and strip the ends.
3. Obtain one of the waterproof (HFB-type) fuse holders included with the control head’s DC Power
Cable, and crimp one half of it to one end of the short section of wire.
4. Using an appropriate electrical terminal, connect this short white wire to unswitched 12-volt DC
power source at or near the vehicle’s fuse box.
5. Cut another section of white wire from the cable, with a length at least long enough to reach from this
fuse holder to the location of the panel-mounted on/off switch.
6. Strip one end of this wire and crimp the other half of the waterproof fuse holder to this wire end.
7. Strip the other end of this wire and, using an appropriate electrical terminal, connect it to the common
terminal of the switch.
8. Connect the white wire of the power cable to the load (switched) side of the switch.
9. Obtain the 3-amp AGC-type fuse included with the cable, and install it into the fuse holder.
10. If not already, mount the switch to the vehicle’s dash panel, or other customer-selected location.
11. Tie and stow these wires as necessary so they remain out of the way of casual contact and wire chafe
is avoided.
12. Label this power switch accordingly. For example: “RADIO ON/OFF.”
7.3.4.2.3 Control Head and Radio Are “Hot Wired”
In the “hot-wired” configuration, the control head and radio 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 7.3.4.2.1, except connect the white wire to unswitched battery power
instead of switched (“Accessory”) power.
MM-012137-001

8 MICROPHONE ATTACHMENT
There are several versions of microphones available for use with the 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 radio 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 8-1, 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.
Figure 8-1: Attaching the Microphone to the CH-721Control Head
As illustrated, do not apply any
force to the thumbscrew when
mating the mic connectors.

9 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 4-1 on page 17) using the hardware and mounting bracket
supplied with it.
2. Route the speaker’s cable to the rear of the control head.
3. Mate the Speaker Cable (item 9 in Table 4-1) 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.
MM-012137-001

10 M5300/M7300 OPTION CABLE
The M5300/M7300 Option Cable CA-012349-001 connects to the radio’s 44-pin I/O cable connector. It
breaks out into several smaller standardized connectors. This allows straightforward access to all external
I/O interfaces provided by the radio. It also helps speed radio removal and re-installation time when
required. The cable is shown in Figure 10-1.
The cable’s 2-pin connector, identified P2, provides connections for an external speaker output in a front-
mount radio installation. As of the publication of this manual, the M5300 is not available in a front-mount
radio configuration. P2 is not used in a remote-mount radio configuration.
The cable’s 6-pin connector, identified P3, provides connections for siren/PA functions. As of the
publication of this manual, this feature is not available.
The cable’s D-subminiature 9-pin connector, identified P5, provides NMEA-formatted GPS serial data
connections for the external computer processing the NMEA-formatted GPS data received by the radio’s
internal GPS receiver. See Section 11 on page 47 for additional information.
The cable’s D-subminiature 25-pin connector, identified P4, provides audio and data interfaces for
connections to non-CAN-based radios. As of the publication of this manual, this feature is not available.

11 GPS NMEA-FORMATTED SERIAL DATA
CONNECTION
To obtain GPS NMEA-formatted serial data from the radio, use of the M5300/M7300 Option Cable
CA-012349-001 is required. Follow this procedure to complete the GPS NMEA-formatted serial data
connections:
1. Obtain M5300/M7300 Option Cable CA-012349-001. Each “leg” of this cable is approximately
65 inches long (166 centimeters).
2. Connect the cable’s 44-pin D-subminiature (DB-44) male connector to the DB-44 female connector
on the rear panel of the radio. Tighten the two jackscrews with a small flathead screwdriver. Do not
over-tighten.
3. Connect the cable’s DB-9 female connector to the computer’s serial port DB-9 male connector —
either directly or with an optional MAMROS0055 serial cable — and tighten the screws until firm.
Route the cabling as required.
4. Follow the manufacturer’s instructions on processing the NMEA-formatted GPS data from the radio.
If the M5300/M7300 Option Cable is not available, a 3-wire serial cable can be field-
fabricated. On the radio end, this cable must interface to the three GPS-related signals of
the radio’s 44-pin I/O Cable connector (pins 7, 31 and 32). See Table 10-1 for additional
information.
Industry software to process GPS information through this interface is not supported by
M/A-COM.
MM-012137-001

12 INITIAL POWER-UP TEST
1. At the radio’s main waterproof (HFB-type) fuse holder installed near the vehicle battery, insert the
15-amp AGC-type fuse that was included with the radio’s DC Power Cable.
2. Tie and stow the fuse holder as necessary to prevent excess vibration/movement.
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. If the installation is wired so the vehicle’s ignition key/switch turns the radio on and off, turn the
switch to the Accessory or Run position.
6. Verify the control head has powered-up by observing its display. If the display is not lit, refer to
Section 7.2.1 as necessary.
Unlike many mobile radio products, the radio 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 on the load side of the fuses, etc. If problems persist, contact M/A-COM’s
Technical Assistance Center (see page 16).
• Consult the Operator’s Manual for operational information.
Refer to the following section for performance test information.
MM-012137-001

13 PERFORMANCE TESTS
This section includes procedures to verify the performance of the radio installation’s mobile antenna
system. The 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 (a 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 radio requires jump-starting, the radio installation’s
main AGC fuse (15-amp) should be removed from the holder prior to jump-starting.
Doing so will prevent damage to the radio system.
Prior to installation, the radio’s power level 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 output from the radio, as the value is set and more
accurately measured in the factory. The values obtained in these test procedures
determine a successful installation only.
13.1 CHANGING OPERATING MODE FOR TESTS
The radio must be operating in the OpenSky Trunking Protocol (OTP) mode during the performance test
procedures presented in this section:
13.1.1 Switching to OTP Mode
1. If necessary, apply power to the radio and turn it on.
2. Rotate the Group Selection Control until Mode Menu appears in the middle line of the display.
Refer to Figure 7-2 on page 33 and/or Figure 7-3 on page 34 as necessary.
MM-012137-001
50
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 radio will reboot and enter OTP
mode as indicated by the display.

If the wattmeter reading is outside the range, verify the radio’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 16).
13.4 TRANSMITTING INTO THE MOBILE ANTENNA
1. Connect the antenna cable from the vehicle-mounted 900 MHz antenna to the wattmeter as shown in
Figure 13-1.
2. If not already, turn the radio on and set it to OTP mode. Refer to Section 13.1 as necessary.
3. Set the radio to a test talk group, if available.
MM-012137-001
52
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 on (begins on page 6).
A peak-power reading RF wattmeter equivalent to the wattmeter specified in Table
13-1 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 if necessary. The arrow
on the face of the slug must point away from the radio and towards the antenna for forward power
measurements.
5. Set the wattmeter to measure peak RF power.
6. Key the radio’s transmitter via the microphone’s PTT button.
7. Compare the wattmeter reading with the target RF output power range of 10 – 20 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.
If the wattmeter reading is outside the range, verify the radio’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 16).
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 to the radio to measure reverse power.
10. Verify the wattmeter is still set to measure peak RF power.
11. Key the radio’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.
If the wattmeter reading is outside the range, make sure the antenna is consistent with the specified
frequency range of the radio. 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 16).
MM-012137-001
53
14. Disconnect the coaxial cable jumper and wattmeter.
15. Permanently connect the cable from the vehicle-mounted 900 MHz antenna to the radio’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 radio
performance but also to harmful exposure to RF electromagnetic energy.
Testing is complete. The radio is now ready for normal communications.
