Maintenance

Charge the Battery

Place the telephone in the desktop charger or in the rack charger. The battery is being charged when the LED on the telephone is steady orange. When the battery is fully charged the LED will be green.

An animated battery icon is also shown in the display indicating charging by starting with its current charge and ending with the full charge. A filled Battery icon indicates a fully charged battery.

Note:

Only use the prescribed chargers for charging.

Replace the Battery

If the standby time for the cordless telephone becomes too low, the battery should be replaced by a new one. Please contact your system administrator or your supplier, for information about new batteries. Replace the battery as described in the illustration below. The battery is connected to the cordless telephone in such a way that no miss-contact is possible.

Note:

The battery cable should be placed in such a way that it cannot be trapped while closing the battery lid, see illustration below.
