Battery Installation, LOW Battery Warning

away from direct sunlight, rain or snow. The best suggested location for the remote sensor for outdoors is under the eave on the north side of the building.

NOTE: When the temperature falls below freezing, the batteries in the outdoor remote sensor may have reduced voltage supply and a shorter effective range. We recommend using lithium batteries at temperatures of 32°F (0°C) and below.

BATTERY INSTALLATION

REMOTE SENSOR

NOTE: Install the batteries; select the temperature in °C or °F before mounting the remote sensor.

•Remove the screws from the battery compartment with a small Phillips screwdriver.

•Install 2 “AA” size alkaline batteries (not included) matching the polarities shown in the battery compartment.

•Replace the battery compartment door and secure the screws.

•Secure the remote sensor in the desired location.

MAIN UNIT

•Remove the battery compartment door.

•Install 2 batteries (UM-3 or “AA” size 1.5V) matching the polarity as shown in the battery compartment.

•Replace the battery compartment door.

LOW BATTERY WARNING

A low-battery indicator [ ] will appear next to the indoor or remote data reading line of the main unit warning that the corresponding batteries need replacement.

GETTING STARTED

WEATHER DISPLAY

After batteries are installed; remote sensor will transmit temperature data at 45 second intervals. The main unit may take up to two minutes to receive the initial readings. Upon successful reception, remote temperature will appear on the top line of the main unit’s display .The main unit will automatically update readings at 45-second intervals.

After communication between the main unit and remote sensor has been established, secure the remote sensor in the desired location.

If no signal is received from the remote sensor within two minutes, dashes [- - -] will be displayed. Press and hold the DOWN (T) button on the main unit for two seconds to initiate another signal search.
