Replacing the Battery

If the standby time for the cordless telephone 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. Attach the battery as in
Figure 14 on page 126. The battery is easy to replace. It is attached inside
the battery lid and is connected to the cordless telephone in such a way that
no miss-contact is possible.
To replace the battery, do the following:
1. Open the battery compartment and remove the battery.
2. Disconnect the battery cable, and replace with a new battery.
