2. Insert the batteries, matching the polarity (+ / -). Press
RESET after each battery change.
3. Select a channel. Make sure you use a different
channel for each sensor.
4. Close the battery compartment.
5. 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 30 m (100 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
factors. You may need to experiment with various locations
to get the best results.
Standard Alkaline batteries contain significant amounts of
water. Because of this they will freeze in low temperatures
of approximately -12°C (10°F). Disposable Lithium
batteries have a much lower threshold for temperature with
an estimated freezing range of below -30°C (-22°F).
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).
