Accepting door calls
The ringing tones for the
front door and apartment
door are different. When a
visitor presses the door bell,
the handsfree telephone
rings and the speech button
flashes.
The call can be accepted
by briefly pressing the spee-
ch 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
tele-phone.

Muting the bell
When the muting button

muted.
