To fold out the stand:
For best results:
• Insert the batteries and select the unit, channel, and time
zone before you mount the sensor.
• Place the sensor out of direct sunlight and moisture.
• Do not place the sensor more than 230 feet
(70 meters) from the main (indoor) unit.
• Position the sensor so that it faces the main (indoor)
unit, min i miz ing obstructions such as doors, walls, and
fur ni ture.
• 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.
NOTE The transmission range may vary and is subject to
the receiving range of the main unit.
You may need to experiment with various locations to get
the best results.
Standard Alkaline batteries contain sig nifi cant amounts of
water. Be cause of this they will freeze in low temperatures
of approximately 10ºF. Disposable Lithium bat ter ies have
a much lower threshold for tem per a ture with an estimated
freezing range of below -40ºF. The Liquid Crystal Display in
out door ther mom e ters will remain operational to -20ºF with
ad e quate power.
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).
sensor, select a different channel
for each sensor.
