OPERATION
General
When the V-2000 is connected to a C. O. line
position or a loop start trunk port, a Tip and Ring
battery feed is provided when the battery feed switch
is in the "ON" position. The voice switching circuit
is turned on when the person making the page begins
to speak. Background music, if connected, will be
turned off and the persons voice will be present on
the output. The voice switching circuit remains on as
long as the person is speaking. When the page is
completed or the person stops speaking for more than
3 seconds, the paging circuit is turned off and
background music is restored to the output. Note:
When the V-2000 is connected to a telephone system
page port, the battery feed switch should be in the
"OFF" position. The operation of the unit is the
same.
