FCC ID: N9Z217S13 Circuit Description The 433MHz crystal oscillator drives the base of Q3 the final/buffer amplifier. The modulation provided by IC (W741E260). The output of Q3 has the matching network consisting of L3 and C21 and C19 that limit the harmonic content and effect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source There is no external antenna. There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 4.5 Volt (“AAA” size battery x 3) 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 polarization.

If you can get to this one first since its the oldest, just dump it into a folder like you did before, and I'll setup metrak job when I get there Thursday. The other two new ones that came today, I'll setup properly on Thursday and refer them to you then. Thanks.
