Accepting door calls
The ringing tones for the
front door and apartment
door are different. When a
visitor presses the door bell,
the hands-free telephone
rings and the muting
button flashes.
The call can be
accepted by pressing the
speech button within 45
seconds after the last ring
tone.
During the call,
the speech
button is
alight. The call is ended by
briefly pressing the speech
button again.
The bus hands-free tele-
phone only ever transmits
speech in one direction and
switches over automatically.
If the automatic switchover
function does not work due
to loud incidental noises at
the door station, it is
possible to force switchover
of the speech direction
from the apartment station
to the door station by
pressing and holding down
the speech button in the
centre. If this button is
released, speech direction
switches over from the door
station to the hands-free
telephone.
Speech volume
During a call, the speech
volume can be set by
pressing + or – at the
speech button.
Actuating the door
release
When you press the door
release, the door from
which the last call came is
opened for 3 seconds.

Switching
on the light
When you press the light
button, the lighting is
switched on, provided this
has been connected by your
electrical installer.
Muting the bell
When the mute button is
pressed briefly, all the
ringing tones are switched
off or on again. The button
lights up red to indicate
that the mute has been
activated. If a visitor rings
the doorbell, the button
flashes for as long as the
hands-free telephone is
muted.
Selecting a
door station
Press the light
button twice to make a
speech connection to the
door station from which the
last call came.
Ring tone volume
The ring tone volume can
be set to 5 different levels:
Hold down the muting
button for 3 seconds
to hear the set ring tone
volume.
The volume
can be set by
pressing + or
– at the speech button.
Save the selected
volume by pressing the
muting button for
3 seconds.
