1.9 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 heatsink fins and the ridged bottom
surface of the radio.
For this to be achieved, there must be a gap of more than 3/8 inch (10 mm)
between the bottom surface of the radio chassis and the mounting surface.
This is illustrated in the following diagram:

2.3 Power Source and Ignition Control
The radio allows for different installation configurations for vehicles with
respect to ignition signal and standby current. 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 Table 3.4 on page 23
and 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).
Notice Although it is possible to connect the radio in line with the
vehicle ignition, this is not recommended, as it may draw too much cur-
rent and damage 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 to the Power Source" on page 18.
If hardware link 1 is fitted (factory default) and the ignition signal is not
used, the standby current is approximately 50mA. To reduce the standby
current to <3mA either:
■remove hardware link 1, or
■connect pin 4 (AUX GPI3) to pin 15 (AGND) of the
auxiliary connector
With the above two options, the radio always stays off when power is first
applied. The radio can only be turned on with the on/off button.
Installation with
Ignition Signal Connect the power cable directly to the power source as described in
"Connecting the Power Cable to the Power Source" on page 18.
Connect pin 4 (AUX GPI3) of the auxiliary connector to the ignition signal
as described in "Connecting to the Auxiliary Connector (Ignition Signal,
Emergency Switch, External Alert Devices)" on page 21.
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
programming application.
The TMAA04-05 ignition sense kit provides a suitable mating plug for
the radio’s auxiliary connector. The plug includes wiring for the the igni-
tion signal and analog ground.

(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 cavity for the
external options connector (fitting an auxiliary connector or external
options connector will not restore the IP54 protection class)
■the grommet of the microphone or hand-held control head is not
installed
■an accessory is added which is not rated to IP54 (e.g. control-head
interface box or hand-held control head remote interface box)

3.3 Mounting the U-Bracket
The U-bracket 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 in the
installation kit, or nuts and bolts (not included).
Caution Although an industrial-strength recloseable fastening system
can be used to support the installation, for safety reasons Tait does not
recommend this as a mounting option.
Notice When mounting the radio on a surface, check whether the
mounting screws will screw into material providing sufficient strength.
Reinforce the mounting surface, if required.
1. If the U-bracket is being mounted over a curved surface, bend the
tabs at the bottom of the U-bracket 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.
Use at least four screws to install the U-bracket.
The screws provided are self-drilling. For more precise positioning, pre-
drill ∅1/8 inch (3 mm) pilot holes for self-drilling screws. Reduce the
hole size in metal that is less than 1/32 inch (1mm) thick.
Notice Ensure that drilling at the selected points will not damage
existing wiring.
3. Drill any holes required for cables and install suitable grommets or
bushings in the holes.
4. Screw the U-bracket in the chosen mounting position using the self-
drilling screws and washers provided. When tightening the screws,
ensure that this does not distort the U-bracket.

3.4 Installing the Antenna
This section provides information on installing an external antenna within
the RF exposure limits.
Install the external antenna according to the antenna manufacturer’s
instructions. Good quality 50 Ωcoaxial cable must be used, such as RG58
or UR76.
Notice Route the cable in a manner that minimizes:
■coupling into the electronic control systems of the vehicle
■coupling of electric vehicle systems, such as alternators, into the
radio
Avoid sharp bends in the cable. These distort the cable and alter its
electrical characteristics.
Warning RF exposure hazard!
To comply with FCC RF exposure limits, mount the antenna at
a location such that no person or persons can come closer than
35 inches (0.9m) to the antenna.
For >25W radios:
■VHF radios must be installed using an antenna mounted
centrally on the vehicle roof, with a gain of 2.15dBi or
5.15dBi.
■UHF and 800MHz radios must be installed using an
antenna mounted either centrally on the roof with a gain
of 2.15dBi or 5.65dBi, or centrally mounted on the trunk
with a gain of 5.65dBi.
For 25W radios:
■The radio must be installed using an externally mounted
antenna with a gain of either 2.15dBi or 5.15dBi.
Terminating the
Antenna Cable 1. Run the free end of the coaxial cable to the radio’s mounting position
and cut it to length, allowing approximately 8 inches (200mm) excess
at the radio end.
2. Terminate the free end of the antenna cable with the mini-UHF plug
or BNC plug (supplied) as shown in Figure 3.4.

3.5 Connecting the Power Cable to the Power Source
This section provides information on connecting the power cable to the
power source.
Power Connector The power connector is the interface to the vehicle battery and an optional
external remote speaker. Connecting a remote speaker is described in
"Connecting a Remote Speaker" on page 20.
Notice This radio is designed to operate from a nominal 12V negative
ground supply and may draw up to 15A of current. The radio will tol-
erate a supply voltage range of 10.8V to 16.0V at the radio.
Selecting the Power
Source In passenger vehicles, the radio is always connected directly to the battery
using the power cable provided.
Notice Do not connect the radio to the center tap of two 12V batter-
ies! This may result in damage to the radio due to earth loops, in partic-
ular when the negative lead is disconnected from the vehicle battery.
It may also result in overcharging or undercharging of the batteries,
reducing their service life.
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 supply voltage larger than 16.0V, such as many trucks, it
is essential to provide a 24V-to-12V converter with a minimum rating of
15A for radios1>25W and 10A for the 25W radio. 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 24, the standby current is approximately 50mA.
When using the ignition signal to turn off the radio, the standby current is
reduced to <3 mA.
To reduce the standby current from 50mA to <3 mA without using the
ignition signal, connect pin 4 (AUX GPI3) and pin 15 (GND) of the
auxiliary connector.
Connecting the
Power Cable Notice Although it is possible to connect the radio in line with the
vehicle ignition, this is not recommended, as it may draw too much cur-
rent and damage 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.
Notice Disconnecting the vehicle’s battery may cause problems with
some electronic equipment, such as vehicle alarms, engine management
systems, and in-vehicle entertainment systems. Check that the vehicle
owner has the necessary information to make all electronic equipment
function correctly after battery reconnection.
Notice If the battery is not disconnected, exercise extreme caution
during the installation and install the fuses only when the installation is
ready to be checked. For more information, refer to "Checking the
Installation" on page 28.
1. Disconnect the vehicle’s battery unless specifically prohibited from
doing so by the customer, vehicle manufacturer, agent, or supplier.
Notice Route the cable in a manner that minimizes coupling of elec-
tric vehicle systems such as alternators into the radio.
Notice 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
(200 mm) excess at the radio end.
3. Plug the power cable into the power connector of the radio.
Warning Danger of fire! The radio’s protection mechanisms
rely on the correct fuses on both the negative and positive power
supply leads being present. Failure to fit the correct fuses may
result in fire or damage to the radio.
The correct fuse types are:
■>25W radios: 20A fuses (Tait IPN 265-00010-81)
■25W radios: 10A fuses (Tait IPN 265-00010-80)
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).

Notice Do not install the fuses until the installation is ready to be
checked. For more information, refer to "Checking the Installation" on
page 28.
5. Insert each end of the negative wire into each of the fuse
crimp-terminals and crimp them to force the metal contacts onto
the wires.
6. Push the two crimp-terminals into the clear plastic fuse cover. Close
the cover while the next steps are completed.
7. Repeat steps 5 and 6 for the positive wire.
8. Connect the negative wire to the battery ground terminal.
9. Connect the positive wire to the battery positive terminal.
Notice Do not install the fuses until the installation is ready to be
checked. For more information, refer to "Checking the Installation" on
page 28.
3.6 Connecting a Remote Speaker
If a high-power remote speaker is
required, Tait recommends using:
■TMAA10-06 high-power remote
speaker for >25W radios
■TMAA10-03 high-power remote
speaker for 25W radios
The remote speaker is installed in
parallel with the radio’s existing
internal speaker. It can be installed at
some distance from the radio, or it can
be used to increase the volume of the audio from the radio’s existing internal
speaker.
If a different speaker is used, receptacles for the speaker pins of the power
connector are provided with the installation kit.
■Connect the speaker to pins 2 (SPK–) and 3 (SPK+) of the power
connector described on page 18.
For more information, refer to the installation instructions provided with
the speaker, or to the relevant section of the service manual.
