20.2.3 Replacing the Battery
If the standby time for the cordless telephone becomes too l ow, the battery
should be replaced by a new one. Please contact your system administrator
or your supplier, for information about new batteries. Attach the battery as
described in the illustration below. The battery is attached inside the battery lid
and is connected to the cordless telephone in such a way that no miss-contact
is possible.
Note: To avoid wearing out the phone's battery connector, use the charger
instead of repeatedly replacing an empty battery with a new one.
To replace the battery:
1. Unlock the lid and remove the battery.
2. Replace with a new battery.
20.3 Desktop Charger

Figure 14 on page 95.
Basic

parameters.
