(+/-).
3.
Press the “
RESET
” key
4.
Slide the battery door back on.
Note
•
Place the sensor in location away from direct
sunlight and rain.
•
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 closer to the main unit during
cold winter months as below-freezing
temperatures may affect battery performance
and signal transmission.
Tip 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).
USING THE BACKLIGHT FUNCTION
In normal mode, press “
CHANNEL
” or “
MIN./MAX.
”
key once to activate the backlight for 5 seconds.
