The programming of the number of rings, melody and privacy duration are carried out through the intercom 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. The BUS termination depends on the position of JP1 on the con-
nection board.
Except for when programming the number of rings, it is necessary to temporarily remove the power supply from the unit after making pro-
gramming changes.
NUMBER OF RINGS, PRIVACY DURATION AND MELODY SELECTION
First of all make a recall to switch on the unit then proceed with the programming operation. To alter the number of rings and select the melody, the in-
tercom must be in program mode. This is achieved by pressing the two following buttons at the same time (left button of the volume control and the right
button of the call tone volume control) see Fig.1.When the programming mode is entered LED 1 (Fig.1) starts flashing. This will automatically reset after
20 seconds of idle time.
Number of rings

When in the programming mode press and hold the “ ” button, LED 1 will stop flashing and LED 3 (Fig.1) will start to flash showing the number of
rings (each flash = 1 ring i.e. 6 flashes = 6 rings)

Once the value of rings has been reached release the “ ” button.

Wait approx 10 seconds for LED 1 to stop flashing to signal that the new value is stored and program mode has exited.
Privacy duration

When in the programming mode press and hold the “ ” button, LED 1 will stop flashing and LED 3 (Fig.1) will start to flash showing the number of
times the button is pressed (each flash = 15 minutes i.e. 8 flashes = 2 hours )

Once the duration required has been reached release the “ ” button.

Wait approx 10 seconds for LED 1 to stop flashing to signal that the new value is stored and program mode has exited.
Melody selection

When in the programming mode, press left or right call tone volume control buttons (press the left button to navigate backward or the right button
to navigate forward through the melodies selection menù) After each press, the melody will be played (during the melody play the LED1 stops flash-
ing);

Before pressing again one of the two buttons to select previous (left button) or next (right button) melody, wait for LED1 to start flashing again then
press and hold one button until the selected melody is played;

Once the required melody is reached, Wait approx 10 seconds for LED 1 to stop flashing to signal that the new value is stored and program mode has
exited.
Notes
The second melody increases its volume at each ring: first ring starts at minimum volume level and adjusts up to the maximum volume level on the last
ring. There are 4 volume levels: Rings after this will all play at full volume.
INTERCOM ADDRESS – SW1.1..7
The table above shows how to set the address of the videophone. Considering that ON = 1 and OFF = 0, mul-
tiply each digit for the relevant decimal weight then add values obtained to get the address: E.g. as highlighted
in the table OFF,ON,OFF,OFF,ON, OFF,ON in binary is equal to 0100101 then multiplying each digit for the
relevant decimal weight you obtain the address that is 37.

ON ON ON ON ON ON ON 1 1 1 1 1 1 1 127
Note
The maximum number of units allowed is 100 but the address of each unit can be a value between 1 and 127.
Set switch 8 to OFF position.
INTERCOMMUNICATION MODE – SW3.1
This switch establishes the intercommunication mode: in OFF position (default) intercommunication is between
units in the same apartment (same addresses but different extension); in ON position the intercommunication is
between units in different apartments (different addresses).
On installations where there are more than one intercom/videophone in the same apartment and intercommunication between different
apartments is required, only one intercom/videophone may be set with this function (SW3.1=ON, SW3.2=OFF, SW3.3=OFF). The other inter-
com/videophones in the apartment must be set for local intercommunication with extension addresses “2-4” (slaves). From the inter-
com/videophone set for intercommunication with other apartments it will be not possible to intercommunicate within the apartment but slave
extensions 2-4 will be able to intercommunicate with each other.
EXTENSION NO – SW3.2..3
If the intercommunication between apartments is enabled (switch 1 of SW3 = ON) leave these two switches in default position (both to OFF). Otherwise,
if the intercommunication is between the same apartment (switch 1 of SW3 = OFF), set the extension addresses starting always from 1.
2 3 Extension No.
OFF OFF 1 (default, master)
ON OFF 2 (slave)
OFF ON 3 (slave)
ON ON 4 (slave)
Notes: Set switch “4” to OFF position.
