Disposable Lithium batteries have a much lower threshold for temperature with an estimated freezing range of below -30°C (-22°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. 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 permanent damage will occur to the unit due to low temperatures). ....

Battery compartment CLOCK CLOCK RECEPTION This product is designed to synchronize its date and time automatically once it is within range of the WWVB-60 signal from the atomic clock in Fort Collins, Colorado. The clock collects the radio signals whenever it is within 3219 km (2000 miles) of a signal. REMOTE SENSOR The sensor collects temperature readings approx. every 40 seconds and sends them to the main unit. The main unit can collect data from up to 3 sensors. TEMPERATURE AND PRESSURE TREND SPECIFICATIONS The temperature and pressure trend icons are based on recent sensor readings.
