SENSOR DATA TRANSMISSION
Outdoor sensor:
The sensor reception icon in the remote sensor area shows
the status:

NOTE If the sensor is not found, check the batteries,
obstructions and remote unit location. Press and hold
SEARCH to force another sensor search.
For best results:
• Place the sensor out of direct sunlight and moisture.
• Position the sensor so that it faces the main unit,
minimizing obstructions such as doors, walls and
furniture.

sky, away from metallic / electronic objects.
• Position the sensor close to the main unit during cold
winter months as below-freezing temperatures may
affect battery performance and signal transmission.

location on the exterior of the home at a height of not more
than 1.5m (5 ft) and which can shield it from direct sunlight
or wet conditions for an accurate reading.
