TROUBLE SHOOTING GUIDE ____________________________________
Note: Most problems are directly related to low battery power. So please
verify that the batteries are fully charged and less than two years old.
No Sound

Verify that no other transmitter is turned "on" on
the same channel.
Bright sunlight, high intense fluorescent or
halogen lights near sensor.
Verify that the infrared beam transmitted from
the transmitter (dark red window) is not being
obstructed by clothing or other solid objects.
Dark colored walls have a tendency to absorb
infrared and do not reflect efficiently.
Glass windows and doors allow competing
infrared light which weakens IR transmission.
Persistent dropouts may require installation of an
additional sensor.
