FCC ID: II622065 Circuit Description The 49.86MHz crystal oscillator drives the base of Q1 the final/buffer amplifier. The modulation provided by Mic. The output of Q1 has the matching network consisting of L 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 10cm long metal wire. 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.
