To charge your phone with a dual charger:
1. Place the dual charger on a flat, horizontal surface and plug the power supply into the dual
charger and then into an appropriate wall outlet.
2. To end any call in progress, press End Call before you place your phone into the dual charger.
Your phone can be off or in standby mode during charging.
3. Place your phone into the dual charger slot, facing forward.
4. Place a spare battery pack in the rear slot, charging contacts down. The front slot takes charging
precedence; the battery pack in the rear slot will begin charging when the phone in the front slot
is fully charged or when the front slot is empty.
Indicator Light
If the phone or battery pack is placed correctly, the red indicator will come on. The indicator light
will not come on if the slot is empty, if the phone is improperly seated or when the dual charger
has no power applied.
If the indicator light is off or flashing, then the phone or battery pack is incorrectly seated.
Remove the phone or battery pack and re-insert.
If the indicator light continues to blink or starts blinking at any time during the charging process
there could be a problem with the battery pack that makes it unusable. Do not continue to charge
the battery pack. Dispose of it properly and do not attempt to use it in the phone. Do not attempt
to open or repair a defective battery pack. Contact your service representative for assistance.
When the phone is charging in standby mode, the extension number and Charging...is displayed. The
battery icon will show charging progress. The phone is fully operational and will ring if called.
When the phone is charging while turned off, only Charging...is displayed and no calls will be received.
When the phone is fully charged and Charge Complete is displayed. If the phone has been turned off
and is turned on, the Charge Complete melody will play.
