Agency approvals and standards compliance
FCC Part 15.105 Notice: 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 Rules. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. 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.
However, there is no guarantee that interference will not occur in a partic-
ular installation. If this equipment does cause harmful 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 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 to
which the receiver is connected
… Consult the dealer or an experienced radio/TV technician for help.
