Installation
The GPS antenna is pre-wired and has a 1 meter foot
cable running through one of the Heyco
Æ
connectors.
Determine location for GPS antenna. It is recom-
mended you place the GPS antenna 1 meter from
dome.
The recommended location for the GPS antenna is
based on having a level location and a clear view of
the sky for the best satellite signal acquisition.
IMPORTANT!
The GPS must be located 1meter
away from obstructions on roof of vehicle and other
obstructions such as trees, tall buildings, etc.
You must
have a clear view of the sky for proper operation.

ENTRY
CABLE
1. Decide the best
location for the cables
to enter
the vehicle,
and
the
location of the switch and re-
ceiver
(see ìInstalling the switch and receiverîon
page 10). Drill a 1/2î hole in the roof, push wires in-
side. Make proper connections.
You must have fi12 VDC power source
.
2. Place cable-entry plate over hole and cables. Screw
in place. Seal plate and screw holes with approved
sealant (not included).
3. Depending on the length of the cable on the roof,
you may need to use cable clamps or wire ties (not
provided) between the unit and your cable-entry plate.
Clamping the cable every 12î-16î should eliminate
any unnecessary
cable movement,
