FCC ID: N8F12706VC Circuit Description The 105.88MHz 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 C9 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 28cm long signal wire. There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 9Volt (“6F22” size battery x 1) primary storage cell.

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 mode ,rotated about all 3 axis(X,Y & Z) to obtain worse position, and manipulating interconnecting cables, rotating turntable and varying antenna height from 1m to 4m in both horizontal and vertical polarizations.
