When installing in multiple rooms where the light is shut off, coaxial cables used in different rooms need not
be matched to the same length.
• All L0 cables are the same length.
• All L1 cables are the same length.
• All M0 cables are the same length.
• L0 and L1 cables need not be the same, since they are used in different rooms.
• M0 and M1 cables need not be the same length, since they are used in different rooms.
Note
The above condition also applies to cases in which two conference systems, both including the Chairman and
Delegate units, are apart from each other in the same room so that communications cannot be made between
the two systems.

When installing in the same space,
• All "L" cables must be identical in length
• All "M" cables must be identical in length.
Note
To facilitate the unification of coaxial cables used in
different connections into the same length, it is highly
recommended that wiring from the Central unit to the
distributor mounted in a ceiling be performed with a
single cable. For other ceiling wiring, using pre-cut
coaxial cables of a slightly longer length will facilitate
making all connections the same length.
