6. GETTING STARTED 

6-1 Installing Batteries 

 Loose the screw and remove the battery 

compartment door located on the bottom of the 
instrument as show below (Fig.1). 

  Install Lithium-ion battery pack. 

  Reinstall the battery cover by aligning it with the 

handle. 

When the battery power is low, the red LED low battery 
indicator illuminates. The battery should be recharged 
as quickly as possible. 

6-2 Charging 

When the battery is being charged, the power 
indicating LED will be on. It will be off after charging is 
completed. 
During the charging period, if the power indicating LED 
blinks, it may be caused by the following reasons. 
(1) Charging period is too long and the detector is 

sending the warning signal. Please disconnect the 
power and try again later. If the situation remains, 
the battery might need to be replaced. 

(2) The temperature of the battery is too high for 

charging operation. Disconnect the power and wait 
until it cools down then try it again. 

(3) This detector is using Lithium-ion rechargeable 

battery and there will not be any charging memory
