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
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 auto­
matic 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 apart­
ment 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
handsfree telephone.
