Place three Alkaline batteries (No.3 battery) in the battery holder. (Refer to the diagrams
embossed in the battery holder, make sure that you insert batteries in correct directions).
Please check the power capacity of the
installed alkaline batteries regularly and
replace them when the power level is low.
NOTE
Batteries are for emergency use (e.g.
accidently power failure), please avoid relying
on the battery power solely when operating
the device. It can work for around 10 minutes
when using the battery power, depending on
the signal strength, the operation environment
and the features you use…etc.
