Operating instructions

Calling a user.

In order to call a user, the receiver must be lifted and a call number with max. 4 digits dialled.
If a series 44x or 54x unit is called, the following message appears for around 2 seconds:
"Call to XXXX". The message then disappears.
If a series 64x is called, the message "Call to XXXX" appears until the called user picks up the receiver.
Then the message "Connection XXXX" is displayed.
After termination of the call, the default setting appears in the display.

Accepting door calls

A door call is signalled by a three-tone chime and LED 3. In the display, the message "Door XXXX
calling" appears.
By picking up the receiver, a connection is immediately created to the calling door. The message
"Connection XXXX" appears.

Door release

The door release key can be actuated at any time. If the door release is actuated from the door
release, the message "door release" appears in the display. If the door loudspeaker cannot switch on the
door release, "not possible 12" appears (see error table).

Transferring calls between two users

In order to transfer a call from a user with an existing speech connection to a third user, simply enter the
number of the third user. If the called user is free, the speech connection is immediately created between
the two users. The display then indicates "Transfer OK"..
If the user is engaged, the original connection between the first two users is retained. The message in
the display then reads „Engaged still connected".

Light switching

The light button can be actuated at any time. If the relevant switching module is successfully
switched, the display "Light" appears. If the switching module fails to switch, the error message "Not
possible 9" appears.

When actuating the key F and a number between 0 and 9, the relevant remote control function is
activated.
If the function is executed, the message "Function OK" is displayed.

Call silencing

The call silencing function is activated by pressing the key. An active call silencing status is indicated
by LED 2 and the message "Call sil. active". The call silencing function is deleted again by pressing the
key again.
If a door loudspeaker call is received during the call silencing status, this is still indicated in the display
and by LED 2, and the video interface is also activated. However, the three-tone chime does not sound.
A speech connection to the door can be created by lifting the receiver.

Dial repeat

Using the button, another call is activated to the last called user.

this call-diversion function will be de-activated again. Up to a maximum of 15 call-diversion transactions
will be possible in the system at the same time.
