GETTING STARTED
Once batteries are in place for the remote unit, temperature
readings will be transmitted at 39-second intervals. The
main unit will search for signals for approximately 4
minutes after the batteries have been installed.
BATTERIES
1. Remove the remote unit battery compartment cover
and insert batteries. Select any of the 3 channels.

Standard Alkaline batteries contain significant amounts of
water. Because of this they will freeze in low temperatures
of approximately 10°F (-12°C). Disposable Lithium
batteries have a much lower threshold for temperature with
an estimated freezing range of below -40°F (-40°C). The
Liquid Crystal Display in outdoor thermometers will remain
operational to -20°F (-28 °C) 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 permanent damage will occur to the unit due
to low temperatures).
