Installation warnings
Warning: Safe radio mounting
■ Mount the radio securely so that it will not break loose in
the event of a collision. An unsecured radio is dangerous
to the vehicle occupants.
■ Mount the radio where it will not interfere with the
deployment of passenger air bags.
■ Do not mount the radio vertically, with the control head
facing down. This will violate compliance with the European Union standard EN 60950, Safety of Information
Technology Equipment.

Warning: Interference with vehicular electronics
Some vehicular electronic devices may be prone to malfunction, due to the lack of protection from RF energy present
when your radio is transmitting.
Examples of vehicular electronic devices that may be affected
by RF energy are:
■ electronic fuel injection systems
■ electronic anti-skid braking systems
■ electronic cruise control systems.
If the vehicle contains such equipment, consult the vehicle
manufacturer or dealer in order to determine whether these
electronic circuits will perform normally when the radio
is transmitting.

Warning: Liquefied petroleum gas powered vehicles
Radio installation in vehicles powered by LP (liquefied petroleum) gas with the LP gas container in a sealed-off space
within the interior of the vehicle must conform to the
National Fire Protection Association Standard NFPA 58. This
standard states that the radio equipment installation must
meet the following requirements.
22 Installation warnings

Important: Non-standard radio installations
The installation U-bracket described in this guide has been
designed so that there is enough airflow around the radio to
provide cooling.
If a non-standard installation method is used, care must be
taken that sufficient heat can be dissipated from the radio
heatsink fins and the bottom surface of the radio chassis.
For this to be achieved, there must be a gap of more than
10mm (0.4 inch) between the bottom surface of the radio
chassis and the mounting surface. This is illustrated in the
following diagram.

10mm

mounting surface

Important: Negative ground supply
TM8100 radios are designed to operate only in a negative
ground system.

Installation warnings 23

English

■ The space containing the radio equipment shall be isolated by a seal from the space containing the LP gas container and its fitting.
■ Outside filling connections shall be used for the LP gas
container and its fittings.
■ The LP gas container space shall be vented to the outside
of the vehicle.

following items:
■ radio control head with connecting loom
■ radio body
■ microphone with microphone clip and screws (TM8110
and TM8115 only)
■ installation kit, consisting of:
— U-bracket with screws
— power cable with DC connector
— 10A fuses
— fuse holders
— BNC antenna plug.

Installation tools
■ Portable drill
■ 8mm (0.3 inch) socket
■ BNC crimp tool

24 Installation planning

Microphone clip installation tools
■ Centre punch
■ Drill bit
■ Pozidriv screwdriver
■ Hammer

Mounting position
Inspect the vehicle and determine the safest and most
convenient location for mounting the radio.
The installation must meet the following requirements:
■ sufficient clearance behind the radio for the heatsink
and cables
■ a large enough flat surface so that the mounting bracket
will not be distorted
■ no danger of the radio interfering with air bag deployment.

Radio installation
Mounting the U-bracket
Screw the U-bracket in the chosen mounting position using
the self-tapping screws provided. At least four screws must
be installed. If the U-bracket is being mounted over a curved
surface, bend the U-bracket tabs slightly.
Important: Check that the U-bracket is not distorted
when the screws are tightened.

Control head handling precautions
Important: The control head contains devices which can
be damaged by static discharges. Always install or
remove the control head in a static-safe environment.
Information on antistatic precautions can be found at the
Electrostatic Discharge Association (ESD) website,
www.esda.org.

Important: During this procedure, take care that the
chassis seal is not damaged. Damage to this seal
reduces environmental protection.
1. On the underside of the radio, insert a flat-bladed screwdriver between the control head and the radio chassis
seal, in either position 1 or 2 .
Note: Insertion points 1 and 2 are indicated
on the radio chassis by a dot-dash-dot
pattern (• •).
2. Use the screwdriver to lift the control head off the chassis
clip, then repeat in the other position.
The control head can now be removed from the
radio body.

Important: The microphone grommet must be installed
whenever the microphone is plugged into the microphone socket. When installed, the grommet has two functions:
■ to prevent damage to the microphone socket when
there is movement of the microphone cord, and
■ to ensure that the control head is sealed against
water, dust and other environmental hazards.
Plug the microphone into the microphone socket on the
control head.
Slide the microphone grommet along the microphone
cord and push two adjacent corners of the grommet into
the microphone socket cavity.
Squeeze the grommet and push the remaining corners
into position.
Check that the grommet is seated correctly in the cavity.

Installing the antenna
Install the external antenna according to the supplier’s
instructions. Good quality 50 ohm coaxial cable must be
used, such as RG58 or UR76.
Important: The cable should be routed in a manner that
minimizes coupling into the electronic control systems
of the vehicle.
Warning: RF exposure hazard
To comply with FCC RF exposure limits, this product must be
installed using an externally mounted antenna with either a
2.15dBi or 5.15dBi gain.
This antenna must not be mounted at a location such that
any person or persons can come closer than 0.9m
(35 inches) to the antenna.
28 Radio installation

Power cable
Important: This radio is designed to operate from a
nominal 12V negative ground supply and may draw up
to 8A of current. The radio will tolerate a supply voltage
range of 10.8V to 16.0V at the radio.
In vehicles with a supply voltage greater than 16.0V, such as
many trucks, it is essential to provide a suitably rated DC to DC
converter. This will isolate the radio from excessive battery voltage and provide the correct DC operating conditions.
Installing the power cable
Important: Disconnecting the vehicle’s battery may
cause problems with some electronic equipment, such
as vehicle alarms, engine management systems and in-car
entertainment systems. Check that the vehicle owner has the
necessary information to make all electronic equipment function correctly after battery reconnection.
1. Disconnect the vehicle’s battery, unless specifically
prohibited from doing so by the customer, vehicle manufacturer, agent or supplier.
If the battery is not disconnected, exercise extreme
caution throughout the installation and install the fuses
only when the installation is ready to be checked (see
“Installation checks” on page 32).
2. Determine where the power cable will be routed.
Important: The power cable should be protected
from engine heat, sharp edges and from being
pinched or crushed.
Radio installation 29

English

Antenna termination
1. Run the free end of the coaxial cable to the radio’s
mounting position and cut it to length, allowing 20 30cm (8 - 12 inches) excess.
2. Terminate the free end of the cable with the BNC
plug supplied.

English

3. Cut the negative and the positive wires where the in-line
fuse holders will be placed (as close to the battery
as possible).
Note: Do not install the fuses until the installation
is ready to be checked.
4. Insert each end of the negative wire into one of the inline fuse holders and crimp them to force the metal
contacts onto the wires.
5. Connect the negative wire to the battery ground.
6. Repeat step 4 for the positive wire and connect it to the
positive terminal of the battery.

Installing the radio in the U-bracket

1. Connect the antenna and power cables to the rear of
the radio.
2. Position the radio in the U-bracket so that the holes in the
U-bracket line up with the holes in the radio chassis.
3. Screw the radio into position using the four thumb screws
but without fully tightening the screws.
4. Position the radio in the U-bracket for best viewing angle,
then tighten the thumb screws.
