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 in-
terference 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

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 inter- ference 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 con-
nected.
– Consult the dealer or an experienced radio/TV
technician for help.
NOTE: Changes or modifications may cause this
unit to fail to comply with Part 15 of the FCC Rules
and may void the user's authority to operate the
