SETUP
Set the A-B-C Switch
The A-B-C switch is located inside
the battery compartment. It can
be set to A, B or C. However,
you must select the same letter
choices for both the sensor and
the display unit in order for the
units to synchronize.
Install or Replace Batteries
AcuRite recommends high quality
alkaline or lithium batteries in
the outdoor sensor for the best
product performance. Heavy duty
or rechargeable batteries are not
recommended.
The sensor requires lithium
batteries in low temperature
conditions. Cold temperatures
can cause alkaline batteries
to function improperly. Use
lithium batteries in the sensor for
temperatures below -4ºF / -20ºC.
1. Slide off the battery
compartment cover. Take note
of the A-B-C switch setting
inside the battery compartment
for display unit setup.
2. Insert 2 x AA batteries into
the battery compartment, as
shown. Follow the polarity
(+/-) diagram in the battery
compartment.
3. Replace the battery cover.
