NOTE: Wiring between VCA and RLC-10R must be electrically shielded, either by installation in
a metal conduit or using shielded cable. When shielded cable is used without conduit (or in
nonmetallic conduit), the shield should be connected to the RLC-10R mounting enclosure.

NOTE: This equipment has been tested and found to
comply with the limits for a Class B digital device, pursuant
to part 15 of the FCC Rule. These limits are designed to
provide reasonable protection against harmful interference
in a residential installation. The equipment generates,
uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions,
may cause harmful interference to radio communications.
However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception,
which can be determined by turning the equipment off an
on, the user is encouraged to try to correct the
interference by one or more of the following measures:
Reorient or relocate the receiving antenna
Increase the separation between the equipment
and receiver
Connect the equipment into an outlet on a circuit
different from that which the receiver is
connected.
Consult the dealer or an experienced radio/TV
technician for help.
