Positioning the telephone
Before using the telephone for the first time, please read the section on safety precautions in this
operating manual. Make sure your telephone is placed on a hard surface with no objects directly
in front of it. (The voice quality could be impaired during hands-free operation).
In view of the extensive range of surfacing materials used on furniture, it is impossible to
guarantee that the base of the telephone (e.g. the feet) will not cause marks. We therefore
recommend that the phone be placed on a non-slip mat.
Emergency operation
If the local 230 V mains supply fails, the ISDN connection is powered directly from the exchange
(emergency operation). However, this remote power supply is only sufficient to power a single
telephone!
If several telephones are operated on the same connection, only one must be authorized for
emergency operation; otherwise the entire ISDN connection is deactivated.
Assign emergency authorization by pressing down the switch behind the Perspex cover for the
auto-dial keys. To deactivate emergency authorization, release the switch again by pressing the
toggle sideways.
The emergency telephone is fully functioning for normal use. The display may switch off
during emergency operation. The ringing volume is set to “low”. To make a call during
emergency operation, lift the handset and dial the number.
The emergency telephone should be clearly labelled using a coloured sticker.
