GETTING STARTED
BATTERIES
Insert batteries before rst use, matching the polarity (+
and -). Press RESET after each battery change.
indicates main unit batteries are low.
NO TE Do not us e rechargeable ba tt er ie s. We
recommend that you use alkaline batteries with this
pro duct for long er usage and lithium batteries in
temperatures below freezing.
REMOTE SENSOR
The sensor collects temperature readings approx. every
40 seconds and sends them to the main unit. The main
unit can collect data from up to 3 sensors.
To set up the sensor:
1. Remove the screws from the battery door.
2. Insert the batteries, matching the polarity (+ / -).

For best results:
• P la ce the se ns or out of dir ec t su nl ig ht 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.
3. Select a channel. Make sure you use a different
channel for each sensor.
4. Place the sensor near the main unit. Press RESET
on the sensor.
5. Simultaneously press CHANNEL and MEM on the
main unit to initiate signal sending between the
sensor and main unit.
6. Close the battery door and secure the screws.
7. Place the sensor in the desired location using the
table stand or wall mount.
The transmission range may vary depending on many
factors. You may need to expe riment with various
locations to get the best results.
Standard Alkaline batteries contain signicant amounts
of water. Be cau se of this the y will free ze in low
temperatures of approximately -12°C (10°F). Disposable
Lith ium batte ries 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).
