6.3 Checking the functions and adjustments
Check anywhere in the installation, during the call and the communication, and make sure
that the +14V – GND and +Uv – GND supply tension is higher than 12,0V.
Check the functions of the terminals and of the outdoor panel: call, communication, access,
audio and video monitoring. The system is adjusted by the producer in what concerns the
audio part, for standard functioning conditions.
How to adjust the volume of the video terminal:
Through consecutive touches of the VOLUME key, different audition levels are obtained:
OFF (mute) – red LED, MEDIUM white-red LED, MAXIMUM – white LED
After checking, leave the terminal on the open volume position (white LED on).
How to adjust the image characteristics on the video terminal:
If due to the type of system (type of cable) the image on display is not qualitative, successively
adjust (on the back of the terminal) until the maximum result is obtained, in the following
order:
1. Impedance adjustment;
2. Luminosity;
3. Chrominance.

6.4 Troubleshooting

Any intervention in the system will be made with the system disconnected from
the 230Va.c. supply network (the phase and null fuses are opened) and from the
accumulator (the +ACC hub is disconnected).
