3 INSTALL BATTERIES

Main Unit: Always install batteries into the main unit first. On the back of the unit, remove the battery compartment cover. Insert 2 AA alkaline (or lithium – See NOTES below) batteries. Replace the cover.

Wireless Sensor: After batteries have been put into the main unit, remove the 4 screws to remove the back cover of the wireless sensor. Insert 2 AA alkaline (or lithium) batteries. Press the “TX” button and replace the back cover and the 4 screws on the sensor. Put the sensor aside for now, and continue to learn about the main unit. Later, in part 5 of this manual you’ll learn more about the wireless sensor.

NOTE: When replacing the batteries for the wireless sensor, remove the batteries from the sensor and clear the sensor’s channel on the main unit by pressing and holding the CHANNEL button when the corresponding channel is displayed. Reinstall the batteries into the wireless sensor and press and release the TX button to synchronize the units.

4 CHOOSE WHERE TO PLACE THE MAIN UNIT and WIRELESS SENSOR

Main Unit: Choose wall mount or table-top placement.

•Choose a location for each unit that is at least 10 feet away from other electronic devices that may interfere with the wireless signal.

•Wall mounting: Use the mounting slot on the back of the unit to hang it from one of the supplied screws.

•Table-top placement: Fold out the integrated table-top stands to place the main unit on a table-top surface.

Wireless Sensor: When placing the sensor, consider these things:

•Although the sensor is designed for outdoor use, placement in a protected area will prolong its life.

•Mounting: Use the mounting slot on the back of the unit to hang it from one of the supplied screws.

•The sensor must be within 100 feet (30 meters) of the main unit.

•The sensor is resistant to weather and to water. It is NOT WATERPROOF.

•Prolonged exposure to cold weather may cause damage to the LCD panel.

•Wireless sensor can be placed outdoors to observe outdoor temperatures and humidity.

•In extremely cold temperatures, it may be necessary to use the included low tempera- ture adaptor to ensure continued operation. This involves bringing the wireless sensor indoors and routing the wired temperature adaptor outside to observe outdoor tempera- tures. See page 4 for more information.
