PROGRAMMING
The videophone setup consists of the following settings:

• Privacy duration;
• Unit address (1..127, switches 1 to 7 of SW1);

• Intercommunication mode (between apartments or within apartment, switch 1 of SW3);
• Extension address (1..4, switches 2,3 of SW3);

The programming of the number of rings, melody and privacy duration are carried out through the videophone push buttons, all
other settings are carried out on the two dip-switch banks (SW1 and SW3) on the rear side of the video monitor (all the settings can
be done without opening the videophone).
Except the number of rings programming, it is necessary to remove temporary the power supply after making any other
programming changes.
