• 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 remote sensor in the desired location. LOW BATTERY WARNING A low-battery indicator [ ] will appear on the remote temperature reading line of the main unit, warning that the remote sensor batteries need replacement. PLACEMENT OF THE REMOTE SENSOR The remote sensor can be mounted on the wall using the recessed screw hole or placed on a flat surface indoors or outdoors. 7 GETTING STARTED After batteries are installed; remote sensor will transmit temperature readings 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 main unit’s display. The main unit will automatically update readings at 45-second intervals. LOST COMMUNICATION If the main unit display line for the remote sensor reading goes blank, refer to the main unit’s User Manual to find out the way to begin a new signal search. If the signal still isn’t received, please make sure that: • The remote sensor is in its proper location. • The distance between main unit and remote sensor is not over 100 feet (30meters). • The path between units is clear of obstacles. Shorten the distance if necessary. • Fresh batteries are installed correctly in both remote sensor and main unit. If there is no reception, please perform the following steps: • Bring the main unit and remote sensor close together. • Remove four (4) small screws from the back of the remote sensor with small Phillips screwdriver, and open the battery compartment. • Remove the batteries from the battery compartment and reinstall them in the same manner. Remote sensor LED indicator will flash showing transmission of the signal. 8 7 • Remove the batteries from the main unit and reinstall them in the same manner. • The remote temperature appeared on the main unit’s display will show that transmission is being received successfully. TRANSMISSION COLLISION Signals from the other household devices such as wireless doorbells, home security systems, and entry control, may interfere with this product or cause temporary reception interruption. This is normal and will not affect the general performance of the product. The transmission and reception of the temperature readings will resume once the interference subsides.
