Selecting the closing impedance
Videointercoms are provided on the back with a jumper J2 that, when set in the correct
position, readjusts the signal coming from the riser to ensure the correct operation of the
connected systems.

Additional functions
Call floor
To receive a floor call you must connect a button (FP) between
terminals A1 and GN of the videointercom.
When the button FP is pressed, the videointercom speaker will
receive a call different from calls from the external stations. The
call is received also if the videointercom is in conversation.
Call repeater
To relaunch the call of the videointercom
in other parts of the apartment add a relay
1471E and a transformer PRS210.
ADJUSTMENTS
The audio levels are set in the factory; settings
on the back of the device must be changed
only if really necessary.
Setting the sound levels.
- If audio is excessively intermittent during
the conversation or the speaker tends to
distort it during the call, it is recommended
to slightly change the microphone sensitivity
using the SENS trimmer on the back of the
video-intercom.
- In case of problems in getting the line in one
of the two directions, slightly increase the
level of the disturbed channel and decrease
the level of the other channel using the
VOL trimmer for the microphone volume
and the menu buttons for the speaker volume
(see chapter "Audio-video adjustment" on
page 2.20).
