Attention!
Continuous charging over several days can damage the interchangeable battery.
Avoid charging processes of more than 12 hours and remove the interchangeable battery from
the battery charger after every charging process, if possible.
1. Connect the AC-adapter to the charging station
and plug the AC-adapter into an electrical outlet.
2.Place one or two interchangeable batteries into the charger.
The charger is ready to use and the charging process will begin when the LEDs corresponding
to each battery light up (refer to sections 6 and 7).
Charging time for one empty interchangeable battery is between 8 to 10 hours (refer to section 11).
When the interchangeable battery is completely charged the current is reduced to a trickle charg-
ing current. The interchangeable batteries may therefore remain in the charger for several hours.
Charging ceases when the interchangeable batteries are removed from the charger.
