Important Information
The transceiver is designed for nominal 12 V negative earth systems.
The equipment is to be installed in accordance with the requirements of local
radio communications authorities and/or Health and Safety regulations.
12 V supply leads, antenna cables and speaker wiring is to be routed as far away as
possible from gas or fuel lines, and any in-vehicle electrical wiring. This reduces the risk to
safety in the event of a leak.
The transceiver should be positioned so that it does not obstruct, or become at risk of
damage from, any occupant or carried items. All cabling should be hidden and not left
loose.
Unpacking
Unpack the container(s) and ensure all items specified on any delivery note are present.
The manufacturer, or their authorised agents, must be notified within ten days of
receipt of equipment if any damage or shortages are found
(customer.su[email protected]).
No consoles or accessories are shipped in the box with the transceiver except the
Power Cable Assembly and the Transceiver Mounting Kit. Due to the many
combinations available the accessory pack must be specified at time of ordering.
Operator Access and Safety
The console must be fitted in such a position that the operators have easy access to the
controls and the microphones when wearing a seat belt. The controls must also be within
the driver's normal field of vision.
Fitting positions above the driver's or passenger's head, or in other positions where the unit
would present a hazard in an accident, must be avoided.
The microphone/handset hook mount must be fitted such that the microphone/handset is
easily accessible and the cable cannot interfere with the vehicle control, or with the driver's
feet.
Preferably, the loudspeaker should be installed such that the grille is facing the operator,
but out of sight of the remote hands-free microphone (if fitted).
Installation
This installation guide provides basic installation information and is not intended to be
definitive, as different types of vehicles will require different installation configurations.
The installer must ensure that fixing screws of an appropriate length are used (some
installations may require different screws). The information given here is general and for
guidance only.
The installation should comply with FCS 1362 CODE OF PRACTICE for the installation of
mobile radio and related ancillary equipment in land based vehicles - see
http://www.fcs.org.uk.
Installation Precautions
Motor vehicle manufacturers make use of electronic vehicle control systems, e.g.,
ignition, anti-skid devices etc. The following information is supplied to ensure that
there is no radio frequency interference effect upon the vehicle's electronic systems.
To prevent interference with any other electronic systems in the vehicle, the antenna
should be mounted as far away as possible from these units and their associated
cables. Refer to the vehicle manufacturer's handbook to locate these items.
Consult the manufacturer's handbook to establish whether it is practical to
disconnect the vehicle battery without affecting devices, such as central locking
mechanisms, engine management computers, security-coded in-car entertainment
units etc.
WARNING
1. Disconnect the vehicle’s battery before commencing installation (be aware
of effect on public broadcast radio security code, alarm systems and some
engine management systems).
2. Do not smoke, or use naked flames, when working near the vehicle’s fuel
system.
3. Ensure that fuel lines, hydraulic lines and existing cables are not damaged
during installation.
4. Ensure that the installation does not impede the normal operation of the
vehicle, including the operation of any safety device, e.g., airbags and
seatbelt tensioners.
5. Speed control, fuel injection, anti-lock braking, navigation, air bag and other
electronic systems are relatively immune to RF interference. However, if
difficulty is experienced or faulty operation suspected, consult the vehicle’s
dealer.
6. This equipment is suitable for 12 V negative earth vehicles only. Use on
other supply systems will result in damage to the equipment.
7. No part of the equipment should be mounted such that injury to the
occupants is likely during an accident.
8. Prolonged operation of the transceiver with the vehicle engine switched off,
could drain the vehicle’s battery.
9. In order to reduce the risk of RF burns the antenna must always remain
connected whilst the equipment is switched on. Under no circumstances
should the antenna connection be connected or disconnected whilst the
equipment is switched on.
Specialised Vehicles
The installation on certain specialised vehicles, such as fuel tankers and fire-fighting
vehicles may be subject to additional safety regulations which must be closely observed.
Prior to commencing an installation on such a vehicle, make sure that any relevant safety
regulations are fully understood.
Petrol and Diesel Powered Vehicles
Ensure that there are no petrol/diesel leaks before commencing an installation involving the
use of electric tools as these can produce sparks. Ensure that no damage to the fuel tank
or fuel lines occurs when drilling holes.
Gas Powered Vehicles
Before installation starts ensure that there are no gas leaks before commencing an
installation involving the use of electric tools as these can produce sparks. DO NOT USE A
NAKED FLAME. Butane and propane are heavier than air, so if there is a leak the gas may
lay on the floor of the boot. The gas is detectable by its characteristic smell. The point of
escaping gas may show signs of frosting. The vehicle owner should arrange for the leak to
be repaired before the installation is commenced.
Ensure that no damage to the gas tank or gas lines occurs when drilling holes. Supply
cables should be run, if possible, on the opposite side of the vehicle to the gas fuel pipe.
Vehicles Fitted with Electronic Devices
In theory, any vehicle electronic systems could be affected by the presence of an RF field of
sufficient intensity, which when detected may cause the device to malfunction. The source
of RF may be a mobile transceiver installed in the vehicle itself or one operating in another
vehicle in close proximity. If interaction did occur, loss of control could result for the
duration of the transmission.
In the interests of safety, the user must be asked to test the vehicle when the installation is
complete.
Installation Guidelines and Recommendations
Temperature Considerations
Reliable transmit operation will be achieved if the transceiver is mounted such that the
finned heat sink receives a free flow of air, i.e., if it is mounted in the normal vertical
orientation with no restriction to the flow of convected air. For any other orientation, varying
degrees of degradation may result.
Fitting the transceiver or console on top of the dash is not recommended. Exposure to
direct sunlight may cause the temperature to rise to over 100 °C. Prolonged exposure to
these temperatures may damage the equipment and invalidate the warranty.
Do not mount the transceiver close to a heat source, e.g., in front of a heater vent.
Installing the Transceiver
Orientation Considerations
It is recommended that the transceiver is mounted within 15 ° of the vertical with the
connectors at the bottom; this reduces the effects of vibration and likelihood of
dust/moisture ingress. Ensure the heat sink fins are in free air as much as possible. The
heat sink may become hot after long periods of transmission; therefore, make sure that
accidental contact with the heat sink is not possible. Ensure sufficient space is provided
above the installation to allow fitment and removal of transceiver (see diagrams below).
Preferred Orientation
Alternative Horizontal Orientation
Location Considerations
The transceiver must be fitted within the interior of the vehicle (excluding the engine
compartment) and protected from the external environment and vehicle cleaning
operations. When fitted, no part of the transceiver may be allowed to obstruct the operation
of the vehicle or impair the safety of any occupant.
Locate the transceiver away from cables carrying very high currents, e.g., the starter motor
cable or the electric traction motor, and its cables, of electric vehicles.
Transceiver Mounting Bracket Installation
The transceiver mounting bracket must be screwed to the desired surface using at least
four screws. The bracket may be used as a template.
Fixing Hole Positions for Transceiver Mounting Bracket (all dimensions in mm)
Transceiver profile includes small clearance allowance; additional allowances should be
made for cables depending on installation configuration.
Cables
Both the remote console and loudspeaker extension cables are colour coded blue at the
transceiver end to aid installation before the transceiver is available.
Ensure that the remote console cable and the loudspeaker cable are routed so that
they are kept well clear of the antenna cable and of any other electronic devices such

3
as electromagnetic systems or AM/FM radios. One end of the remote console cable is
plugged into the 16-way header on the rear of the Standard Console (or Interface &
Handsfree Box of Handset Based Console) and the strain relief/environmental grommet
located in place within the moulding. The other end plugs into either of the “D-type”
Interface sockets on the rear of the transceiver.
If the transceiver is running V9, or earlier, software, do not connect or disconnect the
console(s) while the transceiver is powered. V10, and later, software supports “hot
swapping”.
If a connector is unused, fit the dust cover provided.

WARNING
The transceiver will be damaged if either of the loudspeaker conductors (grey twin
conductor cable) is connected to ground. If the loudspeaker output is to be
connected to other audio systems, an audio isolation transformer must be used.
DC Supply Connection
The power cable plugs into the rear of the transceiver utilising a 15 way D-type connection.
The cable also provides an ancillary connection point for function such as loudspeaker and
other special I/O functions.
1 With the transceiver end of the power connector resting in its intended final position,
route the wires to the vehicle battery; threading the cable through the bulkheads if
required (include the blue wire where ignition switching is not required, see 4 below).
2 The positive power line must include a fuse as close as possible to the power
source. The negative power line must be connected close to the battery-to-vehicle-
body connexion (not directly to the battery) and must not include a fuse.
3 It is recommended that the power cable runs are kept as short as possible.
4 The blue wire provides an ignition sensing input. If ignition switching is required, trim
the wire to length so that it can be wired, via a fuse, to the ignition switch, using the
splicing connector provided. Otherwise this wire must be connected, via a fuse, to
the permanent positive supply.A fuse must always be fitted close to where the wire
is connected.
5 Check the installation and fit the blade fuses. Fuse rating:- Positive supply 10 A,
Ignition sense 1 A (Automotive 19 mm blade type - Littelfuse ATO®).
Antenna Installation
For best all round performance of the product, the antenna should be fitted on the centre of
the vehicle roof. Alternative positions, such as wing mounting, will give degraded
performance. The coaxial feeder should be secured along its length to eliminate the
possibility of damage by sharp edges or moving parts.
Antenna Installation – GPS (optional)
If a GPS receiver is fitted at time of manufacture, a GPS antenna socket will be fitted.
Please note that the SRG3900 transceiver tracks GLONASS and GPS satellites
simultaneously. See customer support bulletin CUS-14-2045.
The antenna unit connects to a SMC connector on the rear of the transceiver and should,
ideally, be mounted on the highest point of the vehicle (i.e., roof) with an uninterrupted view
of the sky, and as far from the TETRA antenna as possible. For mounting, follow
manufacturer’s installation instructions. It is recommended to fit the GPS antenna
connector before connecting the Remote Control Cable.
An active antenna is recommended, the supply of which is on the centre pin, 5 V nominal,
40 mA maximum. This supply feed is short circuit protected.
