Note
Tip 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 -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
