2. Installation
2.1 Planning the Installation
2.1.1 Overview
To ensure trouble-free, efficient installation,
start by inspecting the vehicle to determine
the optimum position for G3
and its an-
tennas as well as the routing of all associated
cabling and wiring.
2.1.2 Location
Often, installations in cars are done in the
trunk, underneath the back window ledge or
on the trunk floor. In vans and small trucks,
it is usually done in the back of the vehicle.
In large vehicles, it is often done in the front
cabin.
Be sure to place the G3
unit in such a way
that:
•
The LEDs can be seen (as an aid in
troubleshooting)
•
Access to the antenna DE-9 connectors
is possible without removing the unit
•
Sufficient air may flow around the unit
to provide adequate cooling
G3
is not fully waterproof, therefore it
should be mounted sufficiently away from
an opened trunk lid or opened tailgate, win-
dows or doors to avoid exposure to rain
and/or snow. It also minimizes the chance
that material can be accidentally thrown on
the unit or of someone bumping against it.
2.1.3 Cable Path
Try to route the cables away from locations
where they would be exposed to heat (ex-
haust pipes, mufflers, tailpipes, etc.), battery
acid, sharp edges, mechanical damage or
where they would be a nuisance to automo-
bile mechanics, the driver or the passengers.
Keep wiring away from automotive com-
puter modules, other electronic modules and
ignition circuits to help prevent interference
between these components and radio equip-
ment.
Try using existing holes in firewall and
trunk wall and the channels above and be-
low or beneath the doors, channels through
doors and window columns that are conven-
ient to run cables and wires.
Whenever possible, install conduit in which
to run the cables.
2.2 Warnings
Before starting installation, review all of the
following warnings.
2.2.1 RF Radiation warning
Qualified personnel must do all antenna in-
stallations. See paragraph 2.5.2 for recom-
mended antenna positioning.
Transmissions when persons or animals out-
side the vehicle are within two feet of the
antenna may result in radio energy radiation
burns or related injuries.
2.2.2 Interference with vehicular
electronics
Certain vehicle electronic devices may be
prone to malfunction due to lack of protec-
tion from radio frequency energy present
when transmitting.
It includes, and is not limited to:
-
Electronic fuel injection systems
-
Electronic anti-skid braking systems
-
Electronic cruise control systems
If the installation vehicle contains such
equipment, consult the dealer for the make
of vehicle and enlist his aid in determining if
such electronic circuits will perform nor-
mally when the radio is transmitting.
2.2.3 Secure mounting
For vehicle occupant(s) safety, mount G3
securely so that the unit will not break loose
in case of an accident or violent maneuvers.
2.2.4 Explosive environments
Operation of vehicular radio transmitters in
explosive environments may be hazardous
and conventional safety precautions must
prevail. These include and are not limited to:
-
Transmitting while fuelling the vehicle.
Do not carry fuel containers in the same
compartment as G3
.
