Installation Precautions
RF energy
Vehicle manufacturers make use of electronic control systems such as the ignition
and anti-skid devices.
Speed control, fuel injection, anti-lock braking, navigation, air bag and other
electronic systems are not adversely effected by RF interference. However, if
difficulty is experienced or faulty operation suspected, contact the vehicle
manufacturer for advice before continuing to install the product.
To prevent interference with any other electronic systems in the vehicle, the
antenna must be mounted away from these devices and their associated cables.
Refer to the vehicle handbook for the location of these devices and information
relating to radio frequency interference.
Specialised vehicles
The installation on certain specialised vehicles such as fuel tankers and fire-fighting
vehicles may be subject to additional safety regulations which must be closely
observed. Before starting to install this product, check the relevant safety
regulations for the vehicle and you understand them.
Petrol powered vehicles
Check the vehicle to ensure that there are no petrol leaks before starting an
installation involving the use of electric tools that may ignite the fuel. Before drilling,
always check the location of fuel lines and electrical wiring looms, Avoid drilling
near the fuel tank.
Vehicle Installation Guide

Gas powered vehicles
Check the vehicle to ensure that there are no gas leaks before starting an
installation involving the use of electric tools that may ignite the fuel.
DO NOT USE A NAKED FLAME. Butane and propane gases are heavier than air,
and may be present in some lower parts of the vehicle and undetectable by smell.
STOP if you notice any sign of a gas leak and inform the vehicle owner
immediately.
Before drilling, always check the location of fuel lines and electrical wiring looms,
Avoid drilling near the fuel tank. Supply cables should be run, if possible, on the
opposite side of the vehicle to the gas fuel pipe.
Vehicles fitted with electronic devices
In theory, any vehicle electronic systems could be affected by the presence of radio
frequency energy, which when detected may cause the device to malfunction. The
source of RF energy may be a mobile transceiver installed within the vehicle or
operating in another vehicle in close proximity. If interaction occurs, loss of control
could result for the duration of the transmission.
In the interests of safety, the operator must test the vehicle under working
conditions on completion of the installation.
Installation guidelines and recommendations
Temperature considerations
Reliable transmit operation is achieved when the transceiver is mounted in a
position that allows free flow of air over the finned heat sink. This is achieved by
mounting the transceiver in the normal horizontal orientation with no restriction to
the air flow. For any other orientation, varying degrees of degradation may result.
Mounting the transceiver on top of the dashboard is not recommended. Exposure to
direct sunlight may cause the temperature to rise to over 80oC (176oF). Prolonged
exposure to these temperatures may damage the product.
Do not mount the transceiver close to a heat source, for example, in front of the
vehicle’s heater vent.
Location considerations
The transceiver must be fitted within the interior of the vehicle (excluding the engine
compartment) and protected from the external environment and vehicle cleaning
operations.
Never install the transceiver directly above the head of the driver or any passenger,
or in any position where it could cause harm in the event of an accident.
Ensure that the installation does not impede the normal operation of the vehicle,
including the operation of any safety devices such as airbags and seatbelt
tensioners.

The transceiver must be installed away from cables carrying very high currents
such as the starter motor cable or the electric traction motor and its cables on
electric vehicles.
Ensure that the cables are routed so that they are kept well clear of any existing
vehicle system cabling.
Secure all cabling to eliminate the possibility of damage by sharp edges or moving
parts.
Pre-installation checks
Before installing the product, check that the electronic systems and lights are
working on the vehicle.
Installing into the vehicle console
The transceiver can be installed into the vehicle console using the optional Mobile
DIN Mount kit (part no. 300-01074).
(1) Mounting bracket (2 pieces)
(2) Screws (2 pieces)
Attach the brackets to each side of the transceiver. Note that the brackets are not
identical and should be fitted with the flat edge to the top of the transceiver. Secure
each bracket into position using a screw.
It may be necessary to connect all cabling before attaching the DIN mount. Slide
the transceiver into the DIN mount until an audible ‘click’ is heard and secure into
position.
Only remove the DIN mounted transceiver using specifically designed DIN mount
removal tools.

DC supply connection
With the transceiver end of the power connector resting in its intended final position,
route the wires to the vehicle battery.
If the power cable needs to be shortened, it must be shortened from the battery
connection end. A fuse must be fitted to the positive line (red wire) when the cable
has been shortened. A new fuse holder must be fitted (not supplied) because the
existing fuse holder cannot be reused. The fuse must be positioned close to the
battery terminal.
CAUTION! Failure to connect the wires to the correct terminal of the battery or power
supply may damage the product and void any warranty.
Connect the red wire (+12V) to the positive terminal on the battery.
Connect the black wire (GND) to the negative terminal on the battery.
Antenna installation
WARNING! Risk of burn injury. Do not touch the antenna when the transceiver is switched
on.
Fitting the DMR mobile antenna
The antenna should be fitted on the centre of the vehicle roof. Alternative positions,
such as wing mounting, will give degraded performance. The coaxial feeder should
be secured along its length to eliminate the possibility of damage by sharp edges or
moving parts.
Refer to the instructions supplied with the antenna for additional safety and
installation instructions.
Fitting the GPS antenna (optional)
The antenna unit connects to a female SMA connector on the rear of the
transceiver. It is recommended that the antenna is mounted on the highest point of
the vehicle in the centre of the roof with an uninterrupted view of the sky. When a
separate DMR mobile antenna is installed, each antenna should be positioned on
the centre line of the roof as far away from each other as possible. An active
antenna is recommended, the supply of which is on the centre pin, 3.3V nominal,
40mA maximum.
Refer to the instructions supplied with the antenna for additional safety and
installation instructions.

Fist microphone
The fist microphone should be located centrally for the operator(s) to access, using
the hanger provided.
The fist microphone connector has a direction indicator. With the direction indicator
facing upwards, rotate the outer self-lock cover in a clockwise direction. Fit the
connector to the transceiver ensuring that the self-lock cover fits over the
corresponding connector on the transceiver. Pressing firmly, rotate the outer self-
lock cover in a clockwise direction until it is secure.
Install the microphone mounting clip in a position that provides the operator with
easy access to the microphone and where the cable cannot interfere with the
vehicle controls or with the driver’s feet. The position must not affect the safety of
the driver when driving the vehicle.
Using the two ST4x16 self-tapping screws, secure the
microphone hanger at the suitable place inside the
vehicle.
Place the fist microphone onto the hanger.
