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

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.

If this equipment does cause interference to radio or television reception, 
which can 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:
