INSTALLATION TECHNICIAN
The modules must be inserted on the frame in
the position selected and fastened using the 4
screws provided.
Refer to the installation diagrams for connection
of the terminals
CAMERA POSITION ADJUSTMENT
These TV camera modules make it possible to
adjust the orientation of the lens of the TV camera
located inside these after tilting back the frame of
the push button panel, in order to overcome any
installation flaws. The adjustment along the vertical
axis in relation to the position set is 10° up and 15°
down.
The adjustment along the horizontal axis in relation
to the position set is 10° in both directions (left-
right).
Orientation along the vertical axis
After loosening lock screw (A), operate on the
specific adjustment unit as follows:
• Pushing plate (B) up, the area framed is moved
toward the top of the screen.
• Pushing plate (B) down, the area framed is moved
toward the bottom of the screen.
Orientation along the horizontal axis
After loosening lock screw (A), operate on the
specific adjustment unit as follows:
• Pushing cross-tie (C) to the right of the operator,
the area framed will be moved toward the right of
the screen.
• Pushing cross-tie (C) to the left of the operator,
the area framed will be moved toward the left of
the screen.
After making the adjustments, tighten lock screw
(A).
ANTI-FOGGING DEVICE POWER SUPPLY
A demister circuit is fitted on the lower side of
the module. Connect terminals (D) ~0 and ~12 in
the circuit continuously to the system 12Vac if the
module is installed in particularly humid locations.
Please note that the demister circuit will be operated
at night only if it is connected to twilight switch.
Connect the circuit using the specific removable
terminal board shown in the drawing.
The circuit intake is negligible. In any case,
where possible, take the voltage from a secondary
transformer.

FOR THE
SPEAKER VOLUME ADJUSTMENT
(Ref. 1755/80, Ref. 1755/41 and Ref. 1755/81
versions only)
On modules equipped
amplification can be adjusted in both directions
(to interior and to exterior) by means of the
two potentiometers accessed by tilting down the
entrance panel frame.
To adjust external volume:
• Turn the trimmer identified as EXT.
clockwise direction to increase volume or in the
opposite direction to reduce this.
To adjust internal volume:
• Turn the trimmer identified as INT.
clockwise direction to increase volume or in the
opposite direction to reduce this.
Transmission values have been set to optimal
values; it is advisable therefore to modify these only
if necessary and to operate only on the trimmer
that adjusts external volume in order to avoid any
downgrading of acoustic balance.
NAME HOLDER LIGHTING
(Ref. 1755/81 and Ref. 1755/41 versions only)
On modules provided with this function, connect
terminals (E) ~0 and ~12 to 12VAC.
