American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 January 7, 2008 RE: HUIZHOU FORYOU GENERAL ELECTRONICS CO., LTD FCC ID: VIPFGEDV6310 I have a few comments on this application. Depending on your responses, kindly understand there may be additional comments. ” 1. It is needed to show the frequency of the oscillators used in the bluetooth module. “FCC 2.1031 (5) A block diagram showing the frequency of all oscillators in the device. The signal path and frequency shall be indicated at each block. 2. Please indicate where I may find FCC part 15.105 information to user statement in the user manual. “15.105 (b) For a Class B digital device or peripheral, the instructions furnished the user shall include the following or similar statement, placed in a prominent location in the text of the manual: 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: -- 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. -- Consult the dealer or an experienced radio/TV technician for help. 3. Please show what RBW and VBW were used on 4.1. Maximum Peak Conducted Output Power measurement. 4. The test procedure page 11 shows RBW=10KHz, but plots show RBW=100KHz on 20 dB bandwidth measurement. Please correct. 5. FYI: According to FCC approved procedure DA00-705 on 20dB bandwidth measurement. The RBW should be set to RBW ≥ 1% of occupied bandwidth, which should be about 10KHz and span should be approximately 2 to 3 times the 20dB bandwidth, but the plots shows RBW=100KHz and span=5MHz, which are too large. 6. According to FCC approved procedure on dwell time measurement, RBW=1MHz should be set in the spectrum analyzer but not RBW=100KHz on page 13.. 7. The plots page 24 for bandedge test should include frequency starting from 30MHz to 24.8GHz. Best regards, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~ George Chen
