Concerning

Radio Frequency

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 with 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 off and on, you can 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.
