Troubleshooting

The PIR Motion Sensor lights up, but the Base
Station does not respond.
The PIR Motion Sensor must be programmed to Base
Station (See Step 4).
Ensure Base Station is on and the volume is turned up.
The Alert is not getting expected transmission
range.
Keep both antennas vertical and keep PIR Motion
Sensor antenna away from trees and metal objects.
Ensure Base Station is in clearest possible sight of the
PIR Motion Sensor. The less objects between the
devices, the longer the range.
PIR Motion Sensor is detecting motion only part of
the time.
Ensure the PIR Motion Sensor is set to the High
Sensitivity setting (See Step 2). To detect cars, it is best
to mount PIR Motion Sensor at height of car's motor and
have it between ten and twenty feet from the road.
Swivel sensor as needed.
