GETTING STARTED BATTERIES Batteries are not supplied with this product. You will need to purchase 2 x UM-4 (AAA) 1.5V alkaline batteries for the main unit, and 2 x UM-4 (AAA) 1.5V alkaline batteries for the remote sensor. Insert batteries before first use, matching the polarity as shown in the battery compartment. For best results, install batteries in the remote sensor before the main unit. Press RESET after each battery change. Do not use rechargeable batteries. NOTE shows when batteries are low. UNIT LOCATION MainIndoor Temperature / Area RemoteOutdoor Temperature / Area REMOTE SENSOR (THR122NX) This product is shipped with a THR122NX Thermo Sensor that collects Temperature data. Data can be collected from only 1 sensor. EN 7 SETUP SENSOR 1.Open the remote sensor battery compartment with a small Phillips screwdriver. 2.Insert the batteries, matching the polarity as shown in the battery compartment. 3.Selec any channel. 4.Place the sensor near the main unit. Press RESET on the sensor. Then, press and hold SEARCH on the main unit to initiate signal sending between the sensor and the main unit. The reception icon on the main unit will blink for approximately 3 minutes while it is searching for the sensor. (Refer to the Data Transmission section for more information.) 5.Close the remote sensor battery compartment. 6.Secure the sensor in the desired location using the wall mount or table stand. For best results: •Insert the batteries and select the channel before you mount the sensor. •Place the sensor out of direct sunlight and moisture. •Do not place the sensor more than 98 feet (30meters) 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. You may need to experiment with various locations to get the best results. Standard Alkaline batteries contain signifcant amounts of water. Because of this they will freeze in low temperatures of approximately 10ºF. Disposable Lithium batteries have a much lower threshold for temperature with an estimated freezing range of below -40ºF. The Liquid Crystal Display in outdoor thermometers will remain operational to -20ºF with adequate power. 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 permane…
