MOUNTING

The V-762 can be used on a desk or wall mounted. The front

Key hole patterns are located on the inside rear surface of the

enclosure for wall mounting. When wall mounting, remove the

front cover, mount and replace the front cover. Use a 11/32” drill

bit to drill the center hole and a 3/16” bit to drill either of the outer

holes.

OPERATION

transmit/receive controls on the talkback control, then fine tune

the volume control on the speaker as needed.

NOTE: Adjustment of the volume control raises and lowers the

reply level when the page control is in the receive mode. The

V-762 will not increase the transmit or receive level beyond the

setting on the page control unit.
