The plate can be mounted using a 3-module back box (horizontal or ver-
tical) or with pressure plugs.

VIDEO SIGNAL STABILISATOR
On the rear of the interphone there is a con-
nector (A-B-C) and a jumper for the video
signal balance. This jumper must be used on
the installations where there are more applian-
ces (interphones or monitors) connected in
series (Fig. 5) or with star connection (Fig. 6).
On the standard configuration displace the
jumper into "Terminazione
(Termination 100 Ohm) only on the last set and
keep the jumpers on the other appliances in
the initial position "Nessuna terminazione" (No
termination" (Fig. 5).

If the image shown on the monitor is distorted, displace the jumper into
one of the alternative positions to the initial one (100 Ohm or 50 Ohm),
so as to eliminate the distortion.

PROGRAMMING
There are three monitor programming modes: assignment of an identifi-
cation code or call code (indispensable), assignment of a secondary
identification code (for monitors associated with a master monitor), pro-
gramming of pushbuttons for auxiliary services and intercommunicating
calls (when necessary).
Programming must be performed with the system switched on, without
active communication and only after connecting the interphones/moni-
tors to the system and programming the panels.
N.B. all the programming or deletion phases must be carried out
with the handset of the interphone or monitor raised.
Identification code programming
The identification code is programmed via an entrance panel (MASTER),
already configured and present on the system.
The monitor is supplied without associated identification code. To verify
this condition, press the lock release pushbutton and the monitor should
emit a triple "Beep".
Programming phase:
1) Press and hold the RESET pushbutton "G" present below the moni-
tor (see Fig 3).
2) Press and hold the lock release pushbutton "D" together with the
RESET pushbutton "G".
3) Release the RESET pushbutton "G", keeping the lock release
pushbutton "D" pressed.
4) After 2 seconds the monitor emits a high tone, the monitor switches
on and communication is enabled with the panel.
5) Release the lock pushbutton "D".
6) On pushbutton entrance panels, press the call button for the moni-
tor, while on alphanumeric keypads, enter the call code and press
pushbutton "".
7) If the system contains a monitor that already has the same associa-
ted identification code, the panel emits a low signal and the opera-
tion should be repeated from point 2.
8) Otherwise the code is associated with the monitor and communica-
tion is terminated.
100 Ohm
On installations with several
appliances (interphones or
monitors) with star connec-
tion, displace the jumper into
"Terminazione 100 Ohm"
(Termination 100 Ohm) in all
appliances.
