Do not disconnect the battery if the vehicle has an anti-theft-coded radio. If equipped with an air bag, avoid discon-
necting the battery if possible. IMPORTANT: Many airbag systems will display a diagnostic code through their
warning light after they lose power. Disconnecting the battery requires this code to be erased, a procedure that can
require a trip to the dealer.
Before beginning the installation:
•
Check with the customer on Status LED location.
•
Remove the domelight fuse. This prevents accidentally draining the battery.
•
Roll down a window to avoid being locked out of the car.
During the installation:
•
Mount the unit in the engine compartment, away from heat sources and areas that must be accessed
for routine maintenance of the vehicle.
•
Mount the unit with the siren portion facing down. This will prevent water damage to the unit.
•
Route the wires away from the unit and make sure they are securely fastened away from the moving
parts of the engine.
•
Place the antenna as high as possible and as straight as possible for maximum operating range.
