button (as specified in the main unit manual) to initiate signal sending between the sensor and the main unit.

6.Close the sensor battery compartment.

7.Secure the sensor in the desired location using the wall mount or table stand.

For best results:

•Place the sensor out of direct sunlight and moisture.

•Do not place the sensor more than 100 m (30 ft) from the main (indoor) unit.

•Position the sensor so that it faces the main (indoor) unit, minimizing obstructions such as doors, walls, and furniture.

•Place the sensor in a location with a clear view to the sky, away from metallic or 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.

The transmission range may vary depending on many	EN
factors. You may need to experiment with various
locations to get the best results.
Wireless ranges can be impacted by a variety of factors
such as extremely cold temperatures. Extreme cold
may temporarily reduce the effective range between the
sensor and the base station. If the unit’s performance
fails due to low temperature, the unit will resume proper
functioning as the temperature rises to within the normal
temperature range (i.e. no permanent damage will occur
to the unit due to low temperatures).

BATTERIES

Insert batteries before first use, matching the polarity (+ and -) as shown in the battery compartment. For best results, install batteries in the remote sensor before the main unit. Press RESET after each battery change.

NOTE It is recommended that you use alkaline batteries with this product for longer performance and lithium batteries in below freezing temperatures (0°C / 32°F). Do not use rechargeable batteries.
