Charging

 

While charging, the charging/incoming indicator illuminates in red. When the battery pack is charged to approximately 95%, the 
charging/incoming indicator illuminates in green. When charging is finished, the charging/incoming indicator goes out.

 

While charging, it is normal for the product to become hot.

 

Depending on the operation procedure and usage environment, the temperature inside the product may get high and the product may 
even get heated. In such case, charging may stop for security reasons.

 

If you perform various operations with a specified charger (sold separately) connected to the product, charging/discharging may take 
place repeatedly in a short time. Frequently charging the internal battery shortens its service life.

 

If the charging/incoming indicator flashes in red, check whether the battery pack is attached and connected properly. If the indicator 
continues to flash, stop charging and contact an au shop or the Keitai Guarantee Service Center.
