Mounting
The V-2000A was designed for wall or table mounting.
The intended mounting orientation will render the
text on the enclosure lid legible when the unit is
viewed. When wall mounting this unit, secure it to
wall studs or a suitable brace (A plywood backboard
2' square and at least 1/2" thick attached to wall studs
would be considered a suitable brace). Make certain
the unit is not mounted near heat sources or strong
magnetic fields. Ascertain control and terminal strip
accessibility.
Four #10 x 3/4" cross-tip round head wood screws are
included for mounting. Fasten the top two screws at
the appropriate location on the mounting surface
(Approximately 3.65" apart and parallel to the floor),
allowing the screwheads to protrude 1/8" to 1/4".
Place the chassis of the unit onto the screwheads at
the mounting slots. Position the two remaining
screws and fasten through the remaining mounting
slots. Complete the mounting by tightening all
screws.
Power Connections
The V-2000A is provided with a three-conductor line
cord. After all required connections have been made,
plug the cord set into appropriate AC wall outlet.

Volume Adjustments

Located on the front cover of the V-2000A are the
screwdriver adjustable volume controls for regulating
the page and background music level. Each volume
control is set by turning it clockwise to increase the
volume and counterclockwise to decrease the volume.
__ a. Page Level: During initial system set up, it is
recommended that the individual speaker
volume controls on the amplified speaker
assemblies be adjusted to 1/2 volume first.
Then, adjust the volume control on the
V-2000A to the desired page level.
__ b. Background music level: Adjust this control
to give the desired background music level
on the paging speakers.
