P9KTX-101FM Transmitter

ÀÌ¿ëÈ£ ́Ô2.gul FCC Statement This device complies with part 15 of the FCC rules and regulations. 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. - The users manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. - Note: 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 off and on, the user is encouraged to try to correct the interference by one or more of the following measures: z Reorient or relocate the receiving antenna. z Increase the separation between the equipment and receiver. z Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. z Consult the dealer or an experienced radio/TV technician for help. CAUTION: Changes or modifications not expressly approved by the manufacturer responsible for compliance could void the user’s authority to operate the equipment.

Subject: RE: Sky Sound Corporation, FCC ID:P9KTX-101, AN02T1848 Dear Mike Kuo Thank you for your cooperation. Please see the attached files. (Report, Setup Photo, External Photo, Internal Photo, Label, Manual, FM Operating explanation, Circuit Diagram, Block Diagram) For your reference... Some part of appliances changed by spurious and radiated emission problem. So, achieved retest and made out again test report. I will send you confimation letter asap. (Applicant's president is examining that confirmation letter) Please check attached files before I will send you confirmation letter. Should you have any questions or comments, please let me know asap.

During the radiated emission tests, the device is connected to Personal computer. Is this intended usage ? The software program that you used in Window media player. How this program is related to the device function ? Question #2: User Manual does not contain the information required under 15.21 of FCC rules. Please provide revised user manual. Question #3: In accordance with 15.215(b) of FCC rules, In no case shall the level of the unwanted emissions from an intenitonal radiator operating under these additional provisions exceed the filed strength of the fundamental emission. There are several spurious emissions are higher than the fundamental emission field strength. Please address this non-compliance issue. Question #4: Since modificatons were made during the final compliance tests. Please provide a cover letter signed by the applicant to agree to incorporate the modifications to each sold in the U.S. Best Regards Mike Kuo / TCB Certifier The items indicated above must be submitted before processing can continue on the above referenced application.
