GETTING STARTED

POWER

Insert batteries before ﬁrst use, matching the polarity (+ and -).

NOTE Install batteries in the remote sensor before the main unit. Press RESET after each battery change. Do not use rechargeable batteries. We recommend that you use alkaline batteries with this product for longer 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 (+ / -).

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.

For best results:

•Place the sensor out of direct sunlight and moisture.

•Do not place the sensor more than 30 meters (100 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 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 -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).

SENSOR DATA TRANSMISSION

Data is sent from the sensor(s) every 40 seconds. The reception icon in the outdoor temperature area shows the status.
