18. FCC Compliance Statement

PART 15.19 This device complies with Part 15 of the FCC Rules. Operation is subject to the following

two conditions: 1. This device may not cause harmful interference, and 2. This device must accept

any interference received, including interference that may cause undesired operation. FCC Interfer-

ence Statement — PART 15.105 (B) 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 equip-

ment off and on, the user is encouraged to try to correct the interference by one of the following mea-

sures: • 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 re-

ceiver is connected. • Consult the dealer or an experienced radio/TV technician for help. RF Exposure

Information This equipment complies with FCC radiation exposure limits set forth for an uncontrolled

environment. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits,

human proximity to the antenna shall not be less than 20cm during normal operation.
