FCC Statement
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the FCC rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This 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. Operation of
this equipment in a residential area is likely to cause harmful interference to radio
communications, in which case the user will be required to correct the interference
at their own expense.
Information to the User

be determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
■
Reorient the receiving antenna.
■
Relocate the equipment with respect to the receiver.
Move the equipment away from the receiver.
■
Plug the equipment into a different outlet so that equipment and receiver are on
■
different branch circuits.
If necessary, the user should consult the dealer or an experienced radio/television
technician for additional suggestions. The user may find the following booklet
prepared by the Federal Communications Commission helpful:
