For best results:
• Place the sensor out of direct sunlight and
moisture.
• Do not place the sensor more than 70 metres
(230 feet) 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 and is subject

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
-40°C(-40°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). The Liquid Crystal
Display in outdoor thermometers will remain operational
to -7°C (-20°F) with adequate power.

SENSOR DATA TRANSMISSION

Data is sent from the sensor(s) every 60 Seconds. The
reception icon shown in the Temperature / Humidity Area
indicates the status.
