Button assignment
The telephone buttons can be
used for functions such as setting
up internal calls or for switching
and control functions. All but-
tons can be double assigned (with

button). Every button is backlit by
a lamp to indicate its switching

tion, please contact your electrical
installer.

Pressing the monitor button will

door which placed the last door
call. This function is only possible if
there is currently no call connected.
Video memory
The bus telephone is equipped
with a video memory. All visitor
pictures are saved with a date
and time. Up to 28 pictures can
be saved in the device. Once the
memory capacity has been used
up, the oldest picture is over-
written each time a new picture is
taken. After a power cut, pictures
saved in the in-house telephone
are deleted. If the video memory
fails to work, consult your electrical
installer.

Cards ranging in size from 32 MB

One picture requires around 1 MB
of storage space. The pictures are
saved in *.tif format with a resolu-

pictures are always stored in the
device and on the card. If the card’s
memory is full, or the maximum
number of 255 images has been
reached, the oldest image is always
overwritten. If the card is inserted,
