FCC Regulations
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 instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case the user
will be required to correct the interference at the user’s own expense.
