FCC Part 15: Radio/Television Interference
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
particular installation. If this equipment does cause
harmful interference to radio or television reception,
which can be determined by turning the equipment on,
the user is encouraged to try to correct the interference
by one or more of the following measures:
qReorient or relocate the receiving antenna.
qIncrease the separation between the equipment
and the receiver.
qConnect the equipment into an outlet on a
circuit different from that to which the receiver
is connected.
qConsult the dealer or an experienced radio/TV
technician for help.

CAUTION: Changes or modifications not expressly
approved by the party responsible for compliance
could void the user’s authority to operate the
equipment.
CAUTION: Shielded interface cables, if any, must
be used in order to comply with emissions limits.
Part 68: Telephone Connection
This equipment complies with Part 68 of the FCC rules.
This equipment has a label that contains, among other
things, the FCC Registration Number and Ringer
Equivalence Number (REN). Upon request, provide the
above information to your telephone company.
The REN value is useful to determine the number of
devices that may be connected to your telephone line
and that will still ring when your telephone number is
called. In most areas, but not all, the sum of the RENs
of all the devices you may connect to one line should
not exceed five (5.0). To be certain of the number of
devices you may connect to your line, as determined by
the REN, you should contact your local telephone
company to determine the maximum REN for your
calling area.
If this equipment causes harm to the telephone network
equipment, the telephone company may discontinue
your service temporarily. If possible, they will notify you
in advance. However, if advance notification is not
possible, you will be notified as soon as possible. You
will be informed of your right to file a complaint with the
FCC.
