A specified telephone paging number must be preprogrammed into the telephone exchange.
The VM amplifier's power can then be switched on remotely by dialing this number from a telephone set,
permitting telephone paging to be made from that telephone. Telephone paging zones can be set when
programming the VM amplifier's zone groups. The telephone exchange's audio signal volume can also
be adjusted.
