manufacturer's instructions for access to
external paging. Make announcement. The
V-2001A automatically disconnects from page.

The V-2001A voice switching circuit is activated
when the person making the page begins to
speak. When the page is completed or the
person stops speaking for more than two
seconds, the paging circuit turns off. Other
functions of the unit remain the same.

Background Music

Background music may be connected to the
V-2001A when using either access method.
Background music mutes on the "page + music"
outputs when a page is made.
