radio communications by interfacing directly to the ap-
paratus radio(s). Six headset connections are provided,
and three have radio transmit capabilities.

CAUTION CAUTION
CAUTION CAUTION CAUTION
When mounting the system components, verify that
drilling through surfaces will not cause damage to
adjacent wiring or equipment.
When selecting your intercom unit location, be sure to
leave at least three inches behind it for cable clearance.
The mounting surface should be flat, fixed, and without
excessive vibration. The surfaces should be able to ac-
cept #8 sheet metal screws.

The Intercom 3000B is provided with a mounting bracket
for dashboard, center console, or overhead mounting.
The mounting bracket slots permit limited rotation of the
Intercom Unit.
Behind-the-head or over-the-shoulder mounting of the
headset modules is usually most convenient. Locate a
flat area that permits surface mounting for each module.
It will be useful to mount a hook or hanger nearby for
storage when the headset is not in use.
