Warning!! Vehicles powered by liquefied petroleum gas
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.
■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.
Caution Negative earth supply
The radios are designed to operate only in a negative earth system.
Caution Insufficient heat dissipation with non-standard radio
installations
An unobstructed flow of air is required over the underside and rear of the
radio to ensure adequate cooling. The installation U-bracket described in
this guide has been designed to ensure such an airflow.
If a non-standard installation method is used, ensure that sufficient heat can
be dissipated from the cooling fins at the rear of the radio as well as from the
ridged underside of the radio. To achieve this, there must be a gap of more
than 3/8 inch (10mm) between the underside of the radio body and the
mounting.

1.3 Choosing an Installation Configuration
Introduction The radio allows for different installation configurations for vehicles with
respect to ignition signal and standby current. For special configurations for
desktop and remote site installations, refer to the service manual.
The installation configurations described below are based on the following
hardware link configuration:
■hardware link 1 (+13.8V battery power sense): fitted
■hardware link 2 (ignition sense): fitted
For more information on the hardware links, refer to the service manual.
Direct Connection to the Power Source The radio’s power cable must always be connected directly to the power
source (battery).
Important Although it is possible to connect the radio in line with the
vehicle ignition, this installation method is not
recommended, as it may draw too much current, resulting
in damage to the vehicle wiring and steering column or
ignition switch. This may also cause the supply voltage of
the radio to drop below the specified level.
The radio can always be turned on and off using the on/off button,
independent of the ignition signal.
Installation without Ignition Signal Connect the power cable directly to the power source as described in
“Connecting the Power Cable” on page 19.
Note If hardware link 1 is fitted and the ignition signal is not used, the
standby current is 28mA. To reduce the standby current to 1mA:
– remove hardware link 1, or
– connect pin 4 (AUX_GPIO3) to pin 15 (GND) of the auxiliary
connector, and program the AUX_GPIO3 line as described below.
Installation with Ignition Signal Connect the power cable directly to the power source as described in
“Connecting the Power Cable” on page 19.
Connect pin 4 (AUX_GPIO3) of the auxiliary connector to the ignition
signal as described in “Connecting to the Auxiliary Connector” on page 21.
Note The AUX_GPI3 line must be programmed to ‘Power Sense
(Ignition)’ and active to ‘High’. For more information, refer to the

Gap between Radio Body
and Mounting Surface Note It may be required to mount the radio upside down in order to
maintain a gap of more than 3/8 inch (10mm) between the bottom
surface of the radio body and the mounting surface.
Inspect the vehicle and determine the safest and most convenient position
for mounting the radio. Make sure that there sufficient clearance behind the
radio for the heatsink and cables.
IP54 Protection
Class Considerations Important The radio is specified to fulfil the requirements of the IP54
protection class. However, the following must be consid-
ered:
The radio must not be mounted in areas, where an accumulation of water
or other liquids can result in the temporary submersion of the radio (e.g.
when using a high-pressure cleaning device).
The IP54 protection class does not apply when:
■the control head is removed from the radio body
■the bungs are removed from the auxiliary connector or the aperture for
the external options connector (fitting an auxiliary connector or external
options connector will not restore the IP54 protection class)
■the microphone grommet is not installed

2.3 Mounting the Radio
Introduction The U-bracket included in the installation kit can be used to install the radio
on the dashboard or on any sufficiently flat surface (e.g. cabin floor or
trunk). The U-bracket can be mounted using the self-drilling screws and
washers provided, or nuts and bolts (not included).
Caution Although an industrial-strength recloseable fastening system
can be used to support the installation, Tait does not
recommend this as a mounting option for safety reasons.
Installation Important When mounting the radio on a surface, check whether the
mounting screws will screw into material providing suffi-
cient strength. Reinforce the mounting surface, if required.
1. If the U-bracket is being mounted over a curved surface, the tabs at
the bottom of the U-bracket can be bent slightly to match the surface
shape.
2. Hold the U-bracket in the position chosen for the radio and use the
mounting holes as a template to mark the mounting locations.
The U-bracket must be installed using at least four screws.
Tip The screws provided are self-drilling. For precise positioning, pilot
holes of ∅1/8 inch (3mm) may be predrilled. Reduce the hole size
in metal that is less than 1/32 inch (1mm) thick.
Important Ensure that drilling at the selected points will not damage
existing wiring.
3. Drill any holes required for cables and fit the holes with suitable
grommets or bushings.
4. Fasten the U-bracket to the mounting points using the self-drilling
screws provided. Ensure that tightening the screws does not distort
the U-bracket.
5. Mount the radio to the U-bracket using the four thumb screws
provided. The radio can be tilted for the best viewing angle.

required to connect the microphone and install the microphone clip.
Connecting the Microphone 1. Plug the microphone into the microphone socket.
Important The microphone grommet must be installed whenever the
microphone is plugged into the microphone socket:
■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.
2. Slide the grommet along the microphone cord and push two adjacent
corners of the grommet into the microphone socket cavity.
3. Squeeze the grommet and push the remaining corners into position.
4. Check that the grommet is seated correctly in the cavity.

connected directly to the battery.
24V-to-12V Converter In vehicles with a supply voltage larger than 16.0V, such as many trucks, it
is essential to provide a suitably rated 24V-to-12V converter. This will isolate
the radio from excessive battery voltage and provide the correct DC
operating conditions. Note that most 24V-to-12V converters already fitted
are not rated sufficiently.
Standby Current When connecting the radio to the battery without using the ignition signal
as described on page 23, the standby current is approximately 28mA.
When using the ignition signal to turn off the radio, the standby current is
reduced to <1mA.
Tip To reduce the standby current from 20mA to approximately 1mA
without using the ignition signal, connect pin 4 of the auxiliary
connector to ground.

Connecting the Power Cable Important Although it is possible to connect the radio in line with the
vehicle ignition, this installation method is not recom-
mended, as it may draw too much current resulting in dam-
age to the vehicle wiring and steering column or ignition
switch. This may also cause the supply voltage of the radio
to drop below the specified level.
Important Disconnecting the vehicle’s battery may cause problems
with some electronic equipment, such as vehicle alarms,
engine management systems, and in-car entertainment sys-
tems. Check that the vehicle owner has the necessary infor-
mation to make all electronic equipment function correctly
after battery reconnection.
Important 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 (refer to “Checking
the Installation” on page 24).
1. Disconnect the vehicle’s battery unless specifically prohibited from
doing so by the customer, vehicle manufacturer, agent, or supplier
due to the type of electrical equipment fitted to the vehicle.
Important The cable must be routed in a manner that minimizes cou-
pling of electric vehicle systems such as alternators into the
radio.
Important Protect the power cable from engine heat, sharp edges and
from being pinched or crushed.
2. Run the power cable between the radio’s mounting position and the
power source and cut it to length, allowing approximately 8 inches
(20cm) excess at the radio end.
3. Plug the power cable into the power connector of the radio.
4. Cut the negative and the positive wires where the in-line fuse holders
will be placed (as close to the power source as possible).
Important Do not install the fuses until the installation is ready to be
checked.
5. Insert each end of the negative wire into one of the in-line fuse
holders and crimp them to force the metal contacts onto the wires.
6. Connect the negative wire to the battery ground.
7. Repeat step 4 for the positive wire and connect it to the positive
terminal of the power source.

2.7 Connecting a Remote Speaker
If a high-power remote speaker is required, the Tait TMAA10-03 speaker is
recommended. Connect the speaker to pins 2 (SPK–) and 3 (SPK+) of the
power connector described on page 19. For more information refer to the
fitting instructions provided with the speaker, or to the accessories manual.
2.8 Connecting to the Auxiliary Connector
Introduction The auxiliary connector can be used to connect external devices and signals
that are typically connected to a radio. These devices and signals include:
■the ignition signal to power up and down the radio
■an emergency switch to power up the radio (if required) and the enter
emergency mode
■external alert devices
Auxiliary Connector The radio’s auxiliary connector is a 15-way standard-density D-range
socket.
Note The space for a mating plug is limited to 1 5/8 inches (41mm) in
width and 11/16 inches (18mm) in height. It is recommended to
test the plug to be used before manufacturing a cable. Tait uses
IPN 240-00020-55 for the plug.

Shielding If the auxiliary cable is longer than 4 feet (1m) it is recommended to shield
the cable and connector backshell. Figure 2.4 shows the recommended
shielding arrangement. The earth braid wire (bare copper) and aluminium
foil should only be earthed at the radio end of the cable.

Ignition Signal The radio can use the ignition signal to be powered up and down. This will
turn the radio off when the ignition key is off to avoid flattening the battery,
and will turn the radio on or return to its previous state (as programmed)
when the ignition key is on.
Note The AUX_GPI3 line must be programmed to ‘Power Sense
(Ignition)’ and active to ‘High’. For more information, refer to the
online help of the application software.
Connect the ignition signal to pin 4 (AUX_GPI3) of the auxiliary
connector.
Emergency Switch The radio allows for connection of an emergency switch to any input line
to enter the emergency mode. If connected to the AUX_GPI2 input line,
the radio can also use ‘emergency power sense’ to power up the radio in order
to enter the emergency mode.
Note The selected input line must be programmed to ‘Enter Emergency
Mode’ and active to ‘Low’. To use ‘emergency power sense’,
hardware link LK3 must be fitted (factory default), and AUX_GPI2
must be used. For more information, refer to the service manual
and the online help of the application software.
Connect a normally closed switch between the pin of the input line (pin 5
for AUX_GPI2) and pin 15 (AGND) of the auxiliary connector.
External Alert Device The radio allows for output to external alert devices using the digital GPIO
lines of the auxiliary connector and the internal options connector.
AUX_GPIO4 can be fitted with a power MOSFET (Q707) in order to
directly connect external alert devices (e.g. flashing light, buzzer, horn relay)
to the radio. Also, resistor R768 must be removed.
Important While the MOSFET is rated at 12A (with heat sink), the
maximum allowable current of the connector and radio’s
earthing system is 2A. Therefore, a horn must not be con-
nected directly to the radio. A horn relay must be used.
Note The selected output line must be programmed to ‘External Alert 1
or 2’, active to ‘Low’, and signal sate to ‘Momentary’.
Connect the external alert device to the pin of the output line (pin 10 for
AUX_GPIO4) and pin 8 (13V8_SW) of the auxiliary connector (or a
different positive battery connection).

2.9 Checking the Installation
1. Insert the fuses into the power leads.
2. Switch on the radio to confirm that it is operational, but do not
transmit.
3. Connect an in-line power meter between the radio and the antenna.
4. Place the radio in transmit mode and measure the forward and
reflected power levels.
5. Less than 4% of the forward power should be reflected. If this is not
achieved, check the installation, including the antenna length.
6. Start reducing the length of the antenna in steps of 0.1 inches to
0.2 inches (2 to 5mm); measure the power levels at each step.
7. Once the reflected power levels are within tolerance, make a call to
another party on the radio.
