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 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 part 2.
2. Insert 2 x AA batteries into the
battery compartment, as shown.
Follow the polarity (+/-) diagram
