2.2 Selecting the Mounting Position
Requirements for
Safe and Convenient
Installation
Ensure the mounting position complies with the following safety 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 and the microphone where they will not interfere with:
■the deployment of passenger airbags
■the vehicle operator controls
■the vehicle operator’s view.
Gap Between
Radio Body
and Mounting
Surface
Note It may be necessary to mount the radio upside down 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 is sufficient clearance behind
the radio for the heatsink and cables.
IP54 Protection
Class Considerations The radio fulfils the requirements of the IP54 protection class.
Important However, do not mount the radio in areas where it can be
temporarily submerged from an accumulation of water or
other liquids (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 microphone grommet is not installed.

2.3 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.
Important 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.
Tip The screws provided are self-drilling. For more precise positioning,
predrill ∅1/8 inch (3mm) pilot holes for self-drilling screws.
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 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.

2.4 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 50Ωcoaxial cable must be used, such as RG58
or UR76.
Important 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:
1. Mount the antenna at a location such that no person or persons can
come closer than 35 inches (0.9m) to the antenna.
2. For 40W/50W 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 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.
3. 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 (20cm) 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 2.4.

2.5 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 21.
Important This radio is designed to operate from a nominal 12V
negativegroundsupplyandmaydrawupto15Aofcurrent.
The radio will tolerate 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.
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 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 50mA.
When using the ignition signal to turn off the radio, the standby current is
reduced to <3mA.
Tip Toreducethestandbycurrentfrom 50mAto<3mAwithoutusing
the ignition signal, connect pin 4 (AUX GPI3) and pin 15 (GND)

Connecting the
Power Cable Important Although it is possible to connect the radio in line with the
vehicle ignition, this is not recommended, as it may draw
too much current 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.
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.
Important 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 27.
1. Disconnect the vehicle’s battery unless specifically prohibited from
doing so by the customer, vehicle manufacturer, agent, or supplier.
Important Route the cable in a manner that minimizes coupling 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

2.6 Connecting a Remote Speaker
If a high-power remote speaker is required, Tait recommends using:
■TMAA10-06 high-power remote speaker for 40W/50W radios
■TMAA10-03 high-power remote speaker for 25W radios.
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 19.
For more information, refer to the installation instructions provided with
the speaker, or to the relevant section of the service manual.
2.7 Connecting to the Auxiliary Connector (Ignition Signal,
Emergency Switch, External Alert Devices)
The auxiliary connector can be used toconnect external devices andsignals
that are typically connected to a radio. These devices and signals include:
■the ignition signal to power up and power down the radio
■an emergency switch to power up the radio (if required) and then 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 inch (41mm) in
width and 11/inch (18mm) in height. It is recommended that you
