Emergency operation
If there is an outage of the local 230 V mains supply, the ISDN connection is powered directly from
the exchange (emergency operation). This remote power supply is only sufficient to power a single
telephone!
If several telephones are operated on the same connection, only one telephone may be authorized
for emergency operation. Otherwise, the ISDN connection will be powered down.
Emergency authorization is assigned by pressing (engaging) the switch behind the perspex cover of
the inscription field, and deactivated by pressing the nipple sideways (disengaging the switch).
The emergency telephone is fully-functioning in normal operation. In emergency
operation the display is switched off. Ringing volume is set to low. Outgoing calls must
be made by lifting the handset and dialling the number.
The emergency telephone should be clearly labelled as such by affixing a coloured
sticker.
