16.2 Replacing the Battery

If the standby time for the cordless phone becomes too low, replace the

battery with a new one. Contact your system administrator or your certified

Aastra Sales partner for information on new batteries. The battery is

connected to the cordless phone in such a way that no miss-contact is

possible.

To replace the battery, do the following (also described in Figure 10):

1. Open the battery lid and remove the battery.

2. Disconnect the battery cable, and replace with a new battery.

3. Make sure the battery cable cannot be trapped while closing the

battery lid.

4. Close the lid.

Note: Do not disconnect the battery unless it needs to be replaced.

The desk charger is used only for charging. The charger is delivered with a

plug-in power supply and is connected into an ordinary wall socket.
