Accepting door calls
The ringing tones for the front
door and apartment door are dif­
ferent. When a visitor presses the
door bell, the handsfree telephone
rings and the speech 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
hands­free telephone only ever
transmits speech in one direction
and switches over automatically. If
the automatic switchover function
does not work due to loud inci­
dental 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, pro­
vided 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
hands­free 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 mute button for
3 seconds.
Within the first 10 seconds
after initiating a function at the
BFSV 850­..., the door call is
signalled with a diminished volume.
Ring tone melody
You can choose between 11 ring
tone melodies. The ring tone is
always set for the door from which
the last call came.
For this reason, first ring the bell at
the front door or apartment door.
(A different ring tone melody can
also be selected for internal or
group calls).
