FCC INFORMATION The Federal Communication Commission Radio Frequency Interference Statement includes the following paragraph: The equipment has been tested and found to comply with the limits for 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 instruction, may cause harmful interference to radio communication. However, there is no grantee that interference will not occur in a particular installation. If this equipment dose 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: nReorient or relocate the receiving antenna. nIncrease the separation between the equipment and receiver. nConnect the equipment into an outlet on a circuit different from that to which the receiver is connected. nConsult the dealer or an experienced radio /TV technician for help. The user should not modify or change this equipment without written approval from WENSHING ELECTRONICS CO.,LTD. Modification could void authority to use this equipment.

This Rule states: The Field Strength of any emission shall not exceed 250 microvolts/meter at 3 meters or 48dBuV/m at 3 meters. However, the Test Report shows the emission level at 43.50 dBuV/m for this rule in error. The device passes the Part 15, Section 239 at 48 dBuV/m. Very truly yours, Frank (for) Sid Sanders
