in the main room, or you may select a separate input
source through the Multiroom menus or remote as
explained on page 45.
The only additional connection required to add video
capabilities to your multiroom system is to connect the
Multiroom Video O either directly to the
video display in the remote room or to any optional
video distribution amplifiers that may be required when
the length of the connection cable is such that addi-
tional amplification is required.

device you should also make a composite or S-Video
connection to permit use of the multiroom system.
• As with all cable installations when running any wiring
inside a wall be certain that the cable carries the
proper NEC rating for the application. The use of
improperly rated cables may present a safety hazard.

requires specific technical knowledge and we recom-

with the equipment being used.
The RS-232 port may also be used as an access
point through which the

connection to a compatible computer At the time
that an upgrade is available instructions for making
the connection and installing the upgrade will be
available through the Product Support area of the
