FCC ID: P95K712RC Circuit Description The 24.930 X2 to 49.86MHz crystal oscillator drives the base of Q1 the final/buffer amplifier. The modulation provided by IC (PT2262). The output of Q1 has the matching network consisting of L1 and C15 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 21cm 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 9 Volt (“6F22” size battery x 1) 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.
