The main unit can support up to 3 sensors. To purchase additional sensors, please contact your local retailer. NOTE Please keep this manual handy as you use your new product. It contains practical step-by-step instructions, as well as technical specifications and warnings you should know about. 1 1 2 3 For best results: · Place the sensor out of direct sunlight and moisture. · Do not place the sensor more than 30 meters (100 feet) 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. The transmission range may vary depending on many factors. You may need to experiment with various locations to get the best results. Standard Alkaline batteries contain significant amounts of water. Because of this they will freeze in low temperatures of approximately -12°C (10°F). Disposable Lithium batteries have a much lower threshold for temperature with an estimated freezing range of below -40°C (-40°F). 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...
