Charging the Replacement Battery
If you have a Charging Station Plus (accessory part) you can use it to charge a
replacement battery pack. The replacement battery pack can be charged simultane-
ously with the handset.
• Fold open the charging station plus (1).
• Place the replacement battery correctly in the designated compartment (2).
• The LED at the base of the charging station changes from green to red and indi-
cates that the replacement battery pack has been inserted correctly and that it is
charging.
• When the replacement battery has been completely charged, the charging pro-
cedure stops. The LED turns back to green.

Recommendations for Battery Usage
Do not throw the battery into a fire, as there is risk of explosion.
To prevent injury or fire damage, do not connect the contact points of the batteries
with other electroconductive components or short-circuit them.
When a new battery is inserted, the charging level is initially unknown to the handset.
The battery symbol is first displayed in the handset after the first complete charging
cycle! Place the handset in the charging compartment
for at least 14 hours after
inserting a new battery in order to completely charge it.
You can leave the handset permanently in the charging station. The battery pack can
not be overcharged.
