cated in the diagram.

Audio unit set-up
The entrance panel defined as being the syste-
m’s main panel must have jumper J1 in place.
Only one main panel can be defined per installa-
tion. Therefore, remove jumper J1 from the audio
units of the rest of the panels in the system.
If necessary regulate the volume level of the
entrance panel and the telephones using the vo-
lume control potentiometers on the audio unit.
