This equipment has been tested and found to comply with the limits for a Class B digi -
tal 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 in-
stalled and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not oc-
cur in a particular 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 the receiver.
Connect the equipment onto 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.
Shielded interconnect cables and a shielded AC power cable must be employed with
this equipment to ensure compliance with the pertinent RF emission limits governing
this device. Changes or modifications not expressly approved by the system's manu-
facturer could void the user's authority to operate the equipment.
