Part No. 6204 is an interphone belonging to the DigiBus series with internal coding for 4 and 8 digit coding
systems. It can be combined with the monitors belonging to the Petrarca series (part No. 6000 and 6003) by
means of brackets or transformation kits. The lock button is enabled only if the interphone has been called.
When the interphone is in the rest state, the same button fulfi ls the function of calling the porter, and sending
the decoding number to the switchboard. The supplementary functions F1, F2, F3, F4, F5, F6, F7 and F8 can
be used by means of the supplementary buttons, part No. 6C59, while the "user-absent" function can be acti-
vated by means of part No. 6153. The interphone can also be connected to a supplementary speech unit such
as part No. 930D.

PROGRAMMING AND OPERATION
The following operations must be carried out only after the entrance panel has been programmed. To program
the interphone number, remove the cover, press the PRG button on the circuit board and hold down the "LOCK"
button.
If the procedure has been effected correctly, the unit will assume programming mode with led (present on the
interphone circuit board) lighting up, at which point "LOCK" push-button (related to door lock) can be relea-
sed. .
If the LED does not light up, the sequence must be repeated. The interphone handset will now enable commu-
nication with the stairway panel so that the latter sends back the interphone code. As the code is transmitted
from the panel to the phone, it will be memorized by the unit and remain stored until further programming, even
in the event of the panel being disconnected from the power supply. The entryphone generates a call sound in
confirmation of the programming operation. Hook the handset again. In case of installations with several entries,
the connector for the entrance panel interphone riser must be removed, leaving only one entrance panel in
operation for the programming phase.
This operation can be repeated any number of times, using other numbers between 0000 0001 and 9999 9999.
