Checking the Power Level
of the Battery

battery is being charged, the Battery Indicator
(
) turns on with different color to show the
power level of the battery.
Remaining battery level: 20% – 100%
Remaining battery level: below 20%
Due to certain characteristics of battery,
the Battery Level Indicators may not
correctly show the remaining power of
the battery, especially under extreme
temperature conditions.
