Fix the top screw (A) in the flush-mounted box (or wall plug), leaving the
screw head to protrude by 2 mm.

back, by placing it close to the wall and then pulling downwards
Complete mounting by screwing the bottom screw (B) into the appropria-
te hole.
VIDEO SIGNAL STABILISATOR
On the lower side of the interphone there is a
connector (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).
On the standard configuration displace the
jumper into "B" only on the last set and keep
the jumpers on the other appliances in the ini-
tial position "A" (No termination" (Fig. 5).
For other connection configurations see the:
TERMINATION TABLE FOR THE TWO WIRE
ELVOX INSTALLATIONS" shown on page 14
and concerning the wiring diagrams enclosed
with the electronic two wire entrance panels.
If the image shown on the monitor is distorted, displace the jumper into
one of the alternative positions to the initial one (B or C), so as to elimi-
nate the distortion.
NOTE: in case of installations with only interphones, keep the jumpers in
"A" position.
PROGRAMMING
There are three interphone programming modes: assignment of an iden-
tification code or call code (indispensable), assignment of a secondary
identification code (for interphones associated with a master interphone),
programming of pushbuttons for auxiliary services and intercommunica-
ting calls (when necessary).
