You must read and observe the safety information on radio
operation provided in the product safety and compliance
information and the user’s guide!

Warning!! RF exposure hazard

To comply with FCC RF exposure limits:

■ VHF radios must be installed using a n antenna mounted centr ally on the

vehicle roof, with a gain of 2.15dBi or 5.15dBi.

■ UHF radios must be installed using an antenna mounted either centrally

on the roof with a gain of 2.1 5dBi or 5.65dBi, or centrally mounted on
the trunk with a gain of 5.65dBi.

This antenna must not be mounted at a location such that any person or
persons can come closer than 35 inches (0.9m) to the antenna.

Warning!! Safe radio mounting

■ Mount the radio secur ely so that it wi ll not br eak loose in t he event of a

collision. An unsecured radio is dangerous to the vehicle occupants .

■ Mount the radio and the microphone wher e they will not interfere with

the vehicle operator controls.

■ Mount the radio and the microphone wher e they will not interfere with

the vehicle operator’s view.

■ Mount the radio and the microphone wher e they will not interfere with

air bag deployment.

Warning!! Interference with vehicular electronics

Some vehicular electr onic devices ma y be pron e to malfunction, due to the
lack of protection from RF energy present when your radio is transmitting.

Examples of vehi cular electronic devices t hat may b e affected by RF energy
are:

■ electronic fuel injection systems

■ electronic anti-skid braking systems

■ electronic cruise control systems.

Warning!! Vehicles powered by liquefied petroleum gas

Radio installation in v ehicles po w er ed b y LP (liquefied p etr oleum) 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 equ ipment shall be isolated b y a seal from

the space containing the LP gas container an d its fitting.

■ Outside filling connections shal l be used for the L P gas co ntainer and its

fittings.

■ The LP gas container space shall be vented to the outside of the v ehicle.

Caution Negative earth su pply

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 re quired over the underside and re a r of the
radio to ensure adequat e cooling. The installation U-bracket described in
this guide has been designed to ensure such an airflow.

If a non-standar d insta llation method is used, ensu re that suffi cient heat can
be dissipated from the cooling fi ns at the rear of the radi o 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 Configurati on

Introduction The radio allows for different installation configurations for vehicles wit h

respect to ignition signa l and standb y current. F or special configur ations 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) : f itted

■ hardware link 2 (ignition sense): fitted

For more information on the hardwar e 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 t he radio in line with the

vehicle ignition, this installation method is not
recommended, as it may dra w too m uch current, resu lting
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 po wer sour ce 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 auxili ary
connector, and pro gram the A UX_G PIO3 line as described below.

Installation with Ignition Signal Connect the power cable directly to the power sour ce as described in

“Connecting the Power Cable” on page 19.

Connect pin 4 (A UX_GPIO3) of the auxili ary 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

2.2 Selecting the Mounting Position

Requirements for Safe and Convenient
Installation

Gap between Radio Body
and Mounting Surface

Make sure the mounting position complies with the requirements of the
following safety warnings:

Warning!! Safe radio mounting

■ Mount the radio secur ely so that it wi ll not br eak loose in t he event of a

collision. An unsecured radio is dangerous to the vehicle occupants .

■ Mount the radio and the microphone wher e they will not interfere with

the vehicle operator controls.

■ Mount the radio and the microphone wher e they will not interfere with

the vehicle operator’s view.

■ Mount the radio and the microphone wher e they will not interfere with

air bag deployment.

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 pos ition
for mounting the radio. Mak e sure that there suff icient clearance behind the
radio for the heatsink and cables.

IP54 Protection
Class Considerations

Important The radio is specified to fulfil the requir ements of the IP54

protection class. Howev e r, the following must be consid­ered:

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 inst all 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-stre ngth reclose able fastening sy stem

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 suffi­cient strength. Reinfor ce the mounting surface , if requi red.

1. If the U-bracket is being mounted over a curved surface, the tabs at
the bottom of the U-bracke t can be bent slightly to match the surface
shape.

2. Hold the U-bracket in the positi on 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 pr o vi ded are self-drilling. For pr ecise position ing, 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 wi ring.

3. Drill any holes required for cables and fit the holes with suitable
gr ommets 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.

Power

Important This radio is designed to operate fr om a nominal 12V neg-

ative ground supply and ma y draw up to 15A of current.
The radio will tolerate a supply voltage range of 10.8V to

16.0V at the radio.

Selecting the Powe r Source In passenger vehicles, the radio is always connected dir ectly to the battery

using the power cable provided.
In trucks, where direct connection to the battery is often not possible, the

radio can be connected to a suitable terminal inside the fuse box, that is
connected directly to the battery.

24V-to-12V Converter In vehicles with a s upply voltage larger than 16.0V, such as many trucks, it

is essential to pro vide a suitably rated 24V-to-12V conv erter. 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 th e ignition signal

as described on page 23, the standby current is approx imately 28mA.
When using the ignition signal to turn off the radio, the standby current is

reduc ed to <1 mA.
Tip To reduce the standby current fr om 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 t he radio in line with the

vehicle ignition, this installation method is not recom­mended, as it may dra w too much cu rrent resulting in dam­age to the vehicle wiring and steering column or ignition
switch. This ma y als o 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 sys­tems. Check that the vehicle o wner has the necessary infor­mation to mak e all electroni c equipment function correctly
after battery reconnection.

Important If the battery is not disconnected, ex ercis e 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 batter y 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 r outed in a manner that minimizes cou-

pling of electric vehicle systems such as alternators into the
radio.

Important Protect the pow er cable from engine heat, sharp edges and

from being pinched or crushed.

2. Run the pow e r cable between the radio’s moun ting 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 negativ e and the positi ve w ires where th e in-line fuse holders
will be placed (as close to the powe r 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 sou rce.

2.7 C onnecting a Remote Speaker

If a high-pow er remote speak er is requir ed, the Tait TMAA10-03 speaker is
recommended. Connect the speaker to pins 2 (S PK–) and 3 (SPK+) of the
power connector described on page 19. For more information r e fer to the
fitting instructions provided with the speaker, or to the accessories manual.

2.8 C onnecting 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 do wn the radio

■ an emergency switch to po wer 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.

Ignition Signal The radio can use the ignit ion signal to be po w er ed up and do wn. Thiswill

turn the radio off when the ignition ke y is off to av oi d flattening the batt ery ,
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 activ e to ‘High’. For more information, refer to t he
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

to enter the emergency mode.

‘emergency pow er sense’ t o pow er up th e radio in or der

Note The selected input line must be pro grammed to ‘Enter Emergency

Mode’ and active to ‘Low’. To use ‘emergency power sense’,
hardw are link LK3 must b e 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 in put line (pin 5
for AUX_GPI2) and pin 15 (AGND) of the auxiliary connector.

External Ale rt D evi c e 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 r e moved.

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 con­nected directly to the radio. A horn relay must be used.

Note The selected output line must be pro grammed 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).
