Diagnostics and Troubleshooting
If you place a fully charged battery in the charger, it will detect the charged
condition and cancel rapid charging. The LED changes to amber, red, and
then green.
Important Note Do not use a battery before it has completed the rapid
charge cycle, even if the handset battery icon reports full strength. The
battery will have a diminished talk/standby time under these conditions.
To discharge a battery:
The rear pocket of the charger has a discharge function which is initiated
when the charger detects that discharging is necessary. You should try dis-
charging a battery when it shows a significant reduction in talk/standby
time.
1 Insert the battery in the rear pocket of the charger.
2 If the LED alternates between green and amber, leave the battery in
the charger to complete discharging.
After the discharge cycle complete the LED changes to red to indicate
rapid charging is in progress.
3 When LED changes to green, you can remove the battery.
