PUSH-BUTTON PANELS
Mody series .
To plan a 4+1 video intercom system all the
button modules can be used, as well as the
back boxes, the protective shelters and the
decorative shields which have been described
on pages 14 to 19. Only the CCD camera
MD40 and the modules MD10, MD11 and
MD12 are several, in that they have been
adapted for functioning with a reduced num-
ber of wires (ref. MD40D, MD10D, MD11D,
and MD12D).

To increase the volume from the amplifier in
the transmission mode, turn the trimmer “
”
in a clockwise direction.

external unit it is necessary to operate as

tling stops (Larsen effect).
