Battery Level Indicator
You can find out the battery's charge level by checking the battery level indicator. To find out the
battery's charge level, press its check button, and observe the battery level indicator lights.
Indicator During Charging
 Pressing the battery check button will cause indicator lights to light in accordance with the current
battery level. The flashing indicator light shows the next level being attained.
 If the battery is fully charged, all of the indicator lights will light when you press the battery check
button.
Important!
 Charging may stop automatically if the ambient temperature while charging is outside the
range of 10°C to 30°C (50°F to 86°F). This is indicated by all charging indicators flashing
slowly. If this happens, remove the AC adapter from the battery and place the battery in a
location whose ambient temperature is between 10°C and 30°C (50°F to 86°F) for a while, and
then try charging in that location.
