External battery charger

The 240mA external battery charger allows you to charge two battery packs at the same time, while a third battery pack is in the handset. The external battery charger has two slots for the battery packs.

Two LEDs, marked 1 and 2, are associated with the two slots. The LEDs light up when the associated slot is active. When you connect the battery charger to a power source, the Nortel logo at the front of the charger is backlit.

To charge a battery pack, insert the battery pack into one of the available slots. When the battery pack is properly inserted, the corresponding LED flashes for two seconds to indicate whether or not the battery is accepted. If the battery is dead, the red LED flashes. The flashing red LED indicates that the battery is not suitable for charging. If the battery is good, the LED flashes red to indicate that charging is in process.

When the battery is fully charged, the LED turns green. It takes approximately 5 hours for a depleted battery pack to be completely recharged.
