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 

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.
