SETUP
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 3-in-1 sensor requires lithium
batteries in low temperature
conditions. Cold temperatures can
cause alkaline batteries to function
improperly. Use lithium batteries in
the 3-in-1 sensor for temperatures
below -4ºF / -20ºC.
1. Press the release lever and pull
off the lower housing of the
sensor.
2. Remove the battery compartment
cover. Take note of the A-B-C
switch setting inside the battery
compartment for step 2.
3. Insert 4 x AA batteries into the
battery compartment, as shown.
Follow the polarity (+/-) diagram
in the battery compartment.
4. Replace the battery cover and
lower housing of the sensor.
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.
