4.1 Selecting the Mounting Position
Inspect the vehicle and determine the safest and most convenient position
for mounting the radio. Tait recommends the use of an equipment
mounting tray designed for the vehicle. These are available from
manufacturers such as Havis-Shields (www.havis.com), Jotto Desk
(www.jottodesk.com), Gamber Johnson (www.gamberjohnson.com), and
Stewart Products (www.stewartproducts.com).
Make sure that there is sufficient clearance for the heatsink and for the
cables. Check cable lengths.
Important Do not mount the radio in areas where it can be sprayed by
a high-pressure cleaning device or temporarily submerged
from an accumulation of water or other liquids.
TM9100 Mobiles: 110 W Mobile Installation Guide Installing the Radio 13

4.2 Installing the Antenna
This section provides information on installing an external antenna within
the RF exposure limits.
Install the external antenna (not supplied) according to the antenna
manufacturers instructions. Good quality 50 coaxial 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, mount the antenna at a location
such that no person or persons can come closer than 44 inches (1.1m) to the
antenna.
VHF radios must be installed using an antenna mounted centrally
on the vehicle roof, with a gain of 2.15dBi or 5.15dBi.
Terminating the
Antenna Cable 1. Run the antenna cable (not supplied) from the antenna to the radio
mounting location and cut it to length, allowing approximately 8
inches (20 cm) excess at the radio end.
2. Strip the end of the coaxial cable as shown in Figure 4.1. Fit the right
angle N-type antenna connector (supplied) to the antenna cable.

4.3 Connecting the Power Cable to the Power Source
Power is supplied to the 110 W mobile via a cable with a DB25 connector
(provided). This plugs into the external RF amplifier, which provides power
to the back of the radio body via an internal loom.
Important This radio is designed to operate from a nominal 12V
negative ground supply and may draw up to 30A of current.
The radio will tolerate a supply voltage range of 10.8V to
16.6V at the radio.
Selecting the Power
Source In passenger vehicles, the radio is always connected directly to the battery.
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 using the ignition signal to turn off the radio, the standby current is
reduced to <3mA. Otherwise, the standby current is 50mA.
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 22.
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.
TM9100 Mobiles: 110 W Mobile Installation Guide Installing the Radio 15
© Tait Electronics Limited October 2005
Important Protect the power cable from engine heat, sharp edges and
from being pinched or crushed.
2. Run the supplied power cable (or one with a higher current rating)
between the radio’s mounting position and the vehicle battery (12 V)
and cut it to length, allowing approximately 8 inches (20 cm) excess
at the radio end.
3. Cut the negative (black) and the positive (red) 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. For more information, refer to “Checking the
Installation” on page 22.
4. 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.
5. Push the two crimp-terminals into the clear plastic fuse cover. Close
the cover while the next steps are completed.
6. Repeat steps 4 and 5 for the positive wire.
7. Connect the negative wire to the battery ground terminal.
8. Connect the positive wire to the battery positive terminal.
Important Do not install the fuses until the installation is ready to be
checked. For more information, refer to “Checking the
Installation” on page 22.
4.4 Installing the Remote Control Head
1. Choose a suitable location for the control head.
2. Mount the Control Head according to the instructions supplied
(IPN: 402-00015-00). Make sure that you follow the warnings and
cautions in these instructions.
Note The remote control head back (TMAA03-03) has already been
fitted to the Control Head and the dual RJ-45 torso interface
(TMAC34-1T) has already been fitted to the radio body.)
3. Run the remote head cable (TMAA04-01) from the control head
location to the radio mounting location.

4.5 Installing the Microphone
This section describes the radio’s microphone connector and the information
required to connect the microphone and install the microphone clip.
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.
Connecting the
Microphone 1. Plug the microphone into the microphone socket.
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.
Installing the
Microphone Clip Install the microphone clip in the most convenient location using the screws
provided. The microphone must be within reach of the user but in such a
position that the PTT (press-to-talk) key cannot be inadvertently activated
or jammed.
Warning!! Safe microphone mounting
Mount the microphone where it will not interfere with:
the deployment of passenger airbags
the vehicle operator controls
the vehicle operator’s view.
Important Only install the microphone clip provided. If a non-

4.6 Connecting to the Ignition Signal
Ignition Sense allows the radio to be turned on and off with the ignition key
of the vehicle. The TM9155R is already fitted with an ignition sense kit,
however it must be programmed for ignition sense operation.
If Ignition Sense operation is desired:
1. Make sure that the AUX GP13 line has been programmed for
ignition sense.
2. Run the yellow wire from the back of the mobile body (underneath
the 110W RF Amplifier) to a 12V signal controlled by the ignition
key.
3. Secure the cable with cable ties using the small holes in the side of the
chassis.
Note The logic thresholds for AUX GPI3 are based on 3V3 levels.
However, AUX GPI3 can be connected directly to a +13.8V
ignition signal.

lines of the auxiliary connector and the internal options connector.
AUX GPIO4 can be fitted with a power MOSFET (Q707) 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 12 A (with heat sink), the
maximum allowable current of the connector and radio’s
earthing system is 2 A. Therefore, a horn must not be
connected 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 state 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).
This means that the negative side of the alert device must be con-
nected to AUX GPIO4 and the positive side to pin 8 (+13V8 SW).
The external alert device must be capable of accepting a voltage of
between 10V and 18V.
4.9 Mounting the Radio
Once the cables are all in position, you attach them to the radio and secure
it in its mounting location. The procedure varies, depending on whether
you are using the base plate and cover.
Warning!! Mount the radio securely so that it will not break loose
in the event of a collision.
To mount the radio without using the base plate and cover:
1. Locate the 110W Mobile chassis in the mounting location and drill
mounting holes.
2. Connect the Control Head cable, Antenna cable and External
Speaker (if installed). Lastly, connect the power cable.
3. Fix the 110W Mobile chassis securely to the mounting surface.

4.10 Checking the Installation
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.
Make sure that you use 30 A fuses. For part numbers,
refer to “Checking the Equipment for Completeness
on page 10.
1. Insert the fuses into the power leads.
2. Turn the ignition on. If necessary, switch on the radio at the control
head.
3. Confirm that it is operational, but do not transmit.
4. Connect an in-line power meter between the radio and the antenna.
5. Transmit and measure the forward and reflected power levels.
The antenna system should achieve a VSWR of better than 2:1. If
VSWR is poor (3:1 or worse), the External RF Amplifier will reduce
its RF power output.
6. If the VSWR is not better than 2:1, check the installation. If
necessary, start reducing the length of the antenna in steps of 0.1
inches to 0.2 inches (2 to 5 mm). Measure the power levels at each
step. For wide-band use, tune for best performance at the top of the
band.
Important Some antennas are pre-tuned and must not be cut. Check
with the manufacturers’ instructions.
7. Once the VSWR is within tolerance, make a call to another party on
the radio.
