• Flashes twice when battery power is low. B. BATTERY COMPARTMENT • Holds two AA-size batteries C. RESET • Resets all previous settings D. CHANNEL SWITCH • Selects the desired channel -1, 2 or 3 E. WALL-MOUNT RECESSED OPENING • Keeps the remote sensor on the wall F. °C/ °F SWITCH • Selects the temperature display in Celsius or Fahrenheit BEFORE YOU BEGIN • We recommend using alkaline batteries for the remote sensor and main unit when temperatures are above 32°F (0°C). We recommend using lithium batteries for the remote sensor when temperatures are below 32°F (0°C). • Avoid using rechargeable batteries. (Rechargeable batteries cannot maintain correct power requirements). • ALWAYS install batteries in the remote sensor before the main unit. • Insert batteries before first use, matching the polarity in the battery compartment • Press RESET after each battery change with a paper clip or similar tool. • Remove protective plastic screen from LCD display (if any). • During an initial setup, place the main unit close to the remote sensor. • After reception is established (the remote temperature will appear on the main unit's display), position the remote sensor and the main unit 7 within the effective transmission range of 100 feet (30 meters). • The remote sensor can be placed indoors or outdoors, depending on the area where the temperature is intended to be measured. If you intend measuring outdoor elements, place remote sensor outdoors • The main unit must be placed indoors. NOTE: 1. Avoid pressing any buttons on the main unit before the remote readings are displayed. 2. The effective operating range may be influenced by the surrounding building materials and how the receiver and transmitter are positioned. 3. Place the remote sensor so that it faces the main unit (receiver), minimizing obstructions such as doors, walls, and furniture. 4. Though the remote sensors are weather-resistant, they should be placed 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 channel and temperature in °C or °F before mounting the remote sensor. • Remove the screws from the battery compartment with a small Phillips screwdriver. • Set the channel. The switch is located in the battery compartment. Channel 1 is typically selected if only one remote sensor 7 8
