RF Energy
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 e󰀨ect 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 a󰀨ecting devices, such as central
locking mechanisms, engine management computers, security-coded in-car
entertainment units etc.
Specialised Vehicles
The installation on certain specialised vehicles, such as fuel tankers and re-
ghting 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/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 oor 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 a󰀨ected by the presence of
an RF eld of su󰀩cient intensity, which when detected may cause the device
to malfunction. The source of RF may be an SCG22 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
This installation guide provides basic information about installing the
mobile radio into land based vehicles (not marine based vehicles or
motorcycles).
The installation of this product must be performed by a suitably
skilled and technical competent person such as a qualied vehicle
installation technician.
This product can be installed into various makes and models of vehicles and
therefore these instructions are not a denitive guide to installing the product
into vehicles.
The installation should comply with FCS1362 CODE OF PRACTICE for the
installation of mobile radio and related ancillary equipment in land based
vehicles (see http://www.fcs.org.uk).
Before you start the installation, ensure that you have all the accessories,
including cables.
Operator Access and Safety
Install the console in a position where the operator has easy access to the
controls and the microphone when wearing a seat belt. The controls must also
be within the driver's normal eld of vision.
DO NOT t the console above the driver's or passenger's head, or in other
positions where the console would become a hazard in an accident or is at
risk of damage from any occupant or carried items.
The microphone/handset hook mount must be tted 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 tted).
