Acu-Rite 1604 사용자 설명서

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.

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.
