Mobile Antenna Installation
Install the vehicle antenna external to the vehicle and in accordance with:
a. The requirements of the antenna manufacturer/supplier
b. Instructions in the radio installation manual.
Control Station Operation
When radio equipment is used to operate as a control station, it is important that the antenna be
installed outside the building and away from places where people may be in close proximity.
INSTALLATION WARNINGS
For vehicles with electronic anti-lock/anti-skid brakes, Motorola recommends the following radio
installation precautions and vehicle braking system test procedures to ensure that the radio, when
transmitting, does not interfere with the operation of the vehicle braking system. Refer to your vehicle
service manual for details of your vehicle’s braking system, or contact your dealer directly.
Installation Precautions:
1. Always provide as much distance as possible between the braking modulator unit and the radio,
the radio antenna, and associated transmission line. Before installing the radio, determine the
location of the braking modulator unit in the vehicle. Depending on the make and model of the
vehicle, the braking modulator unit may be located in the trunk, under the dashboard, in the
engine compartment, or in some other cargo area. If you cannot determine the location of the
braking modulator unit, refer to the vehicle service manual or contact a dealer for the particular
make of the vehicle.
2. If the braking modular unit is located on the left side of the vehicle, install the radio on the right
side of the vehicle, and conversely.
3. Route all radio wiring, including the antenna transmission line, as far away as possible from the
braking modular unit and associated braking system wiring.
4. Never activate the radio transmitter while the vehicle is in motion and the vehicle trunk lid is open.
Braking System Tests:
Be sure the following vehicle testing is done in an isolated area. The following procedure checks for
the most common types of interference that may be caused by a radio transmitter to vehicle braking
system:
1. Run the vehicle engine at idle speed and set the vehicle transmission selector to PARK. Release
the brake pedal completely and key the radio transmitter. While NOT speaking into the
microphone, verify that there are no unusual effects (visual or audible) to the vehicle lights, or
other electrical equipment and accessories.
2. Repeat Step 1, except do so while speaking into the microphone.
3. Press the vehicle brake pedal slightly; just enough to illuminate the vehicle brake light(s). Then
repeat Steps 1 and 2.
4. Press the vehicle brake pedal firmly and repeat Steps 1 and 2.
NOTE Refer to Table 1 for rated power and minimum distance values for transmitting
antennas.
WARNING: Disruption of the anti-skid/anti-lock braking system by the radio transmitter may
result in unexpected vehicle motion.
!

v
5. Ensure that there is a minimum of two vehicle lengths between the front of the vehicle and any
object in the vehicle’s forward path. Then, set the vehicle transmission selector to DRIVE. Press
the brake pedal just far enough to stop the vehicle motion completely. Key the radio transmitter.
Verify that the vehicle does not start to move while NOT speaking into the microphone.
6. Repeat Step 5, except do so while speaking into the microphone.
7. Release the brake pedal completely and accelerate the vehicle to a speed between 25 and 40
kilometres (15 and 25 miles) per hour. Ensure that a minimum of two vehicle lengths is
maintained between the front of the vehicle and any object in the vehicle’s forward path. Have
another person key the radio transmitter, and verify that the vehicle can be braked normally to a
moderate stop while NOT speaking into the microphone.
8. Repeat Step 7, except do so while speaking into the microphone.
9. Release the brake pedal completely and accelerate the vehicle to a speed of 30 kilometres
(20 miles) per hour. Ensure that a minimum of two vehicle lengths is maintained between the front
of the vehicle and any object in the vehicle’s forward path. Have another person key the radio
transmitter, and verify that the vehicle can be braked properly to a sudden (panic) stop while NOT
speaking into the microphone.
10. Repeat Step 9, except do so while speaking into the microphone.
11. Repeat Steps 9 and 10, except use a vehicle speed of 50 kilometres (30 miles) per hour.
OPERATIONAL WARNINGS
Potentially explosive atmospheres
Blasting caps and areas
WARNING: For radios installed in vehicles fuelled by liquefied petroleum gas, refer to the
(U. S.) National Fire Protection Association standard, NFPA 58, for storage, handling, and/or
container information
WARNING: Turn off your Two-Way radio when you are in any area with a potentially explosive
atmosphere, unless it is a radio type especially qualified for use in such areas (e.g. FM or
Cenelec approved). Sparks in a potentially explosive atmosphere can cause an explosion or
fire resulting in bodily injury or even death.
WARNING: To avoid possible interference with blasting operations, turn off your radio when you are
near electrical blasting caps. In a “blasting area” or in areas posted “turn off two-way radio”, obey all
signs and instructions.
NOTE The areas with potentially explosive atmospheres referred to above include fuelling areas
such as: below decks on boats; fuel or chemical transfer or storage facilities; areas where
the air contains chemicals or particles, such as grain, dust or metal powders; and any other
area where you would normally be advised to turn off your vehicle engine. Areas with
potentially explosive atmospheres are often but not always posted.

INSTALLATION
1.0 Introduction
1.1 General Information
There are two methods of installing your mobile radio:
1. Using the direct mounting trunnion and power cables supplied with a standard radio package.
2. Mounted in the car radio cut-out (using the required GLN7320_ mounting kit, per ISO7736).
An accessory connector on the rear of the radio (see Figure 1-4 Connections to the Back of Radio)
enables you to attach different accessories required for the installation.
A ten-pin telephone type connector on the front control head panel (see Figure 1-5 Transmission
Hump Mounting (Top) and Below Dash Mounting (Bottom)) provides for the connection of various
types of microphones.
1.2 Plan the Installation
1. Mount the radio horizontally near the driver, so the driver can easily view, access and operate
the controls and accessories.
2. Ensure that the location is not exposed to dirt and moisture.
3. Verify that there will be sufficient space around the mobile unit for air flow and installation.
4. Check that there is enough routing space for the power cable connector and the antenna
coaxial cable.
5. Plan the best place to run connections to minimize pinching, crushing, and overheating of
wires and cables.
2.0 DC Power Cable Installation
2.1 Planning the Power Cable Installation
The 3 metres (10 feet) DC power cable shipped with the radio should be long enough to be installed
in most vehicles. Take the following precautions before you begin:
 Whenever possible, avoid routing the cable above the catalytic converter.
 Use grommets whenever a cable has to pass through a hole in a metal panel.
NOTE In a vehicle with an airbag, make sure that the mounting location of the mobile radio, or of
any radio accessory, is not in the deployment path of the air bag.
CAUTION: This radio must be operated only in negative ground electrical systems.
Operating the radio on a positive ground system will cause the cable fuse to short-circuit.
Check the vehicle ground polarity before you begin the installation.
!

1-2 INSTALLATION
The following table lists power cables available for this radio:
2.2 Power Cable Installation Procedure
Begin the power cable installation as follows:
1. Determine a routing plan, keeping in mind where the radio is to be mounted.
2. Locate an existing hole with grommet in the vehicle fire wall, or use a 9.5 mm (3/8-inch) bit to
drill an access hole in the fire wall. Install a grommet with a 5 mm (3/16-inch) inside diameter
into the hole to protect the power cable.
3. From inside the vehicle, feed the red and black leads (without the lugs attached) through the
access hole and into the engine compartment. (See Figure 1-1 Power Cable Routing into the
Engine Compartment)
Table 1-1 Power Cables
Number Description Rating
HKN4137_ Low power cable to battery 1-25W; 15A fuse; 14 AWG 3m
HKN4191_ High Power Cable to battery 25-45W; 20A fuse; 12 AWG 3m
CAUTION: Improper handling with the power cable may cause shorting to ground. Ensure
that during radio installation the power cable fuse is removed.
CAUTION: Be very careful not to damage existing wires.

4. Connect the black lead of the power cable to the nearest vehicle chassis ground point (using
the provided ring lug if necessary). Shorten the black lead to remove any excess cable.
(See Figure 1-2 Power Cable Assembly.)
5. Place the fuse holder close to the battery. Ensure that it is not near any hot engine
component. Mount the fuse holder using its mounting hole and dress the wires as required.
6. Insert the stripped end of the red lead of the fuse holder into the ring lug hole and crimp it.
Connect the fuse holder red adapter lead plug to the mating receptacle on the red lead of the
power cable. (See Figure 1-2 Power Cable Assembly.)
7. Connect the power cable black lead directly to the vehicle chassis ground.
8. Connect the red lead ring lug from the fuse holder to the positive (+) battery terminal. Make
sure the adapter cable is connected to the main power cable red lead.
Carefully check that all connections are proper. Insert the fuse into the fuse holder and close the
cover. (See Figure 1-2 Power Cable Assembly).
NOTE Locate a good vehicle ground point. The vehicle frame provides the best ground. Optimum
radio performance can only be achieved with a very low resistance ground connection.
Verify that the connections between the battery negative terminal, vehicle chassis, and
engine block have low resistance.

3.0 Trunnion Installation
3.1 Planning the Mounting Trunnion Installation
The standard mounting trunnion allows the radio to be mounted to a variety of surfaces.
1. Ensure the surface can support the weight of the radio.
2. Although the trunnion can be mounted to a plastic dashboard, it is recommended that the
mounting screws be located so they penetrate the supporting metal frame of the dashboard.
3.2 Trunnion Installation Procedure
1. Select either the transmission hump or an open underneath portion of the dash to mount your
radio. (See Figure 1-5 Transmission Hump Mounting (Top) and Below Dash Mounting
(Bottom)). When mounting the trunnion on the transmission hump, be careful that the
transmission housing is not affected.
2. Use the trunnion mounting bracket as a template to mark the hole positions on the mounting
surface. Use the innermost three holes for a curved mounting surface, such as the
transmission hump, and the three outermost holes for a flat surface such as under the dash.
3. Center-punch the spots you marked and use a 4 mm (5/32-inch) bit to drill a hole at each
location.
4. Secure the trunnion mounting bracket to the mounting surface with the three self-tapping
screws provided. (See Figure 1-5 Transmission Hump Mounting (Top) and Below Dash
Mounting (Bottom)).
5. Slide the radio into the trunnion. Secure the radio with the two thumb screws provided.
(See Figure 1-3 Radio into Trunnion.)

Antenna Installation 1-5
3.3 Control Head Mounting Position
The control head is designed to be removed from the housing and turned to any position within a
180° radius. This provides multiple mounting options for the radio. For example, the radio may be
mounted on either side of the vehicle transmission tunnel to facilitate the safest and most
ergonomically ideal position. The control head may then be turned to provide the most convenient
access.
To reposition the control head:
1. Insert a small flat blade screwdriver, or similar instrument, in the recess between the control
head and the radio housing.
2. Press until the control head releases. Repeat the process on the opposite side of the radio.
3. Pull the control head away while ensuring that the flex connector remains attached.
4. Rotate the control head, and fold the flex circuit to align it to the new position.
5. Push the control head into the housing until the protruding tabs snap into place.
4.0 Antenna Installation
4.1 Mobile Radio Operation and EME Exposure
Observe the following caution and electromagnetic energy exposure (EME) statements when
installing antennas:
To assure optimal radio performance and that human exposure to radio frequency electromagnetic
energy is within the guidelines referenced in this document, transmit only when people inside and
outside the vehicle are at least the minimum distance away from a properly installed,
externally-mounted antenna.
CAUTION: The contact surface of the flex circuit should be facing the printed circuit board.
CAUTION: Use caution when installing antennas with mobile radio equipment using
transmitter power in excess of 7 Watts.
NOTE For low-power mobile radios (7 Watts, or less), there are no antenna type or
installation restrictions.
!
!

1-6 INSTALLATION
The table below lists the minimum distance for several different ranges of rated radio power.
4.2 Selecting an Antenna Site
1. Install the vehicle antenna external to the vehicle and in accordance with:
a. The requirements of the antenna manufacturer/supplier
b. Instructions in the radio installation manual.
2. The best mounting location for the antenna is in the center of a large, flat conductive surface.
In almost all vehicles, mounting the antenna in the center of the roof will satisfy these
requirements. A good alternate location is in the center of the trunk lid. If you use the trunk lid,
ensure that the trunk lid is grounded by connecting grounding straps between the trunk lid
and the vehicle chassis.
3. Ensure the antenna cable can be easily routed to the radio. Ensure that the antenna cable is
routed separately and not in parallel to any other vehicle wiring or mobile radio cable wiring.
4. Check the antenna location for any electrical interference.
5. If the vehicle is equipped with an electronic anti-lock braking system (ABS) and the antenna
will be trunk mounted, then install the antenna on the side opposite to the braking modulator
box. This minimizes radio interference to the modulator box from the radio.
6. Motorola offers a glass-mount antenna as an accessory. It is usually mounted on the rear
window. This antenna should be placed as high as possible on the vehicle. Ensure that a
rear-window defogger element does not touch the inductive “button” on the mounting foot of
the antenna.
7. Make sure the mobile radio antenna is installed at least 30.48 cm (1 foot) away from any other
antenna on the vehicle.
4.3 Antenna Installation Procedure
1. Mount the antenna according to the instructions provided with the antenna kit. Run the
coaxial cable to the radio mounting location. If necessary, cut off the excess cable and install
the cable connector.
2. Connect the antenna cable connector to the radio antenna connector on the rear of the radio.
(See Figure 1-4 Connections to the Back of Radio.)
Table 1-2 Rated Power and Distance
Rated Power of Vehicle-Installed
Mobile Two-Way Radio Minimum Distance from Transmitting Antenna
7to15Watts 30.5 Centimetres (1 Foot)
16 to 50 Watts 61 Centimetres (2 Feet)
More than 50 Watts 91.5 Centimetres (3 Feet)
NOTE Any two metal pieces rubbing against each other (such as seat springs, shift levers,
trunk and hood lids, exhaust pipes, etc.) in close proximity to the antenna can cause
severe receiver interference.
