Replacing the Battery

If the standby time for the cordless phone becomes too low, replace the battery with a new one. Contact the system administrator or your certi- fied Aastra Sales partner for information on new batteries.

The battery is easy to replace. It is attached inside the battery lid and is connected to the cordless phone in such a way as to avoid misinsertion. Attach the battery as described in figure 15 on page 118.
