KEYPAD BACKLIGHTING
The VM102 Master has keypad backlighting, which can be toggled on and off, by pressing
the “DOOR” button while in PROGRAM mode.
SIX WIRE OPERATION
Although System One is designed to operate optimally using 8-wire cable, it will also
operate using 6-wire cable if required.
On 6-wire systems, music is interrupted at all stations during private communication
whereas with 8-wire systems, music is only interrupted at the stations involved.
Selecting Six Wire Mode
Where the Room Stations on a 6-wire system are programmed to the “6-wire” option, the
Master on a 6-wire system, must be left programmed to the “8-wire” option.
Selecting 6-wire mode at the Master is done with two wire links and a jumper.
In accord with the cable termination diagrams for VM102 Masters using 6-wire telephone
cable, ensure the following:
��COM1 terminal is linked (with wire) to the MUS1 terminal
��COM2 terminal is linked (with wire) to the MUS2 terminal
Fit the shunt provided, across the link labelled “L1” on the audio interface PCB, situated on
the bottom right hand corner, on the rear side of the Master fascia.
In PROGRAM mode, ensure the green L.E.D. is on (8-wire mode).
If it is not, press the “HOUSE” button to select “8-wire” mode (green L.E.D. on).
Press the “CLEAR” button to exit PROGRAM mode, or leave in PROGRAM mode, to alter
other programming options.
