Power Management 4-3
The Main Battery Status LEDs show the power level of the battery,
based on the battery’s original capacity. Over time, the capacity of the
main battery pack gradually declines and it will no longer charge to its
original level. To see the true power level of the battery, you need to
check the main battery pack LEDs.
Main Battery Pack LEDs
Check the main battery pack LEDs by following these steps:
1. Remove the battery as instructed in Replacing the Main Battery
Pack on page 4-7.
2. Press and release the TEST button. The current battery power
level LED is displayed.
3. If the battery no longer charges to full (F) capacity, but only to
1/2 or less, you should replace the battery to avoid unexpected
power loss.
