FCC CAUTION: FCC CAUTION: The manufacturer is not responsible for radio interference caused by unauthorized modifications to this equipment. Such modifications could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with 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 instruction, may cause harmful interference to radio communications. However, these is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television receiption, 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 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 technical for help.

FCC ID: G6D6277H Circuit Description The 49.86MHz crystal oscillator drives the base of Q2 the final/buffer amplifier. The modulation provided by IC1. The output of Q2 has the matching network consisting of L4 and C11 that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source The antenna consists of a 39cm long Metal Antenna. There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 6 Volt (“AA” size battery x 4) primary battery

Measurements in both horizontal and vertical polarities were performed. During the test, each emission was maximized by: having the EUT continuously working, investigate all operating modes, rotated about all 3 axis (X, Y & Z) to obtain worst position, manipulating interconnecting cables, rotating turntable, varying antenna height from 1m to 4m in both horizontal and vertical polarizations. The emissions worst-case are shown in Test Results of the following pages. *:OATS [Open Area Test Site] located at HKSTC with a metal ground plane on filed with the FCC pursuant to section 2.948 of the FCC rules, with Registration Number: 90657.

Alice, please provide the following information for New Bright Application FCC ID: G6D6277H in order to complete the application for Certification 1. The spectral plot does not clearly demonstrate bandedge compliance, per Section 15.235(b). Please provide a plot that shows the bandedges +/- 10 kHz, and that the emission level at these points complies with Section 15.209. Use the Marker-Delta function from the peak of the fundamental emission to the emission level outside of the 10 kHz guard bands, on either side of the authorized band, to demonstrate the required amount of attenuation. Once this correct information is provided we will continue the processing of this application.
