FCC ID: P2VWIRELESSKIT Circuit Description The 17.734476MHz (x 5 to 88.67MHz) crystal oscillator drives the base of Q3 the final/buffer amplifier. The modulation provided by Mic. The output of Q3 has the matching network consisting of L1 and C13 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 12cm long of wire. There is no external ground connection. The ground is only that of the printed circuit board. Electric current is supplied by a 3 Volt (“CR2032” button cell 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.

Marianne Bosley To:[email protected] Cc:Chris Harvey Subject:MET#11627 FCC ID:P2VWIRELESSKIT Hi Alice, Below is the question that surfaced due to the technical review: RT questions: 1. Section 3.2 of the test report states that a "typical modulating signal used as input". Was the maximum volume available on the output of the cellphone used as input? 2. The statement regarding the 200 kHz bandwidth does not describe how the modulation is limited, such that the bandwidth of the output signal never exceeds 200 kHz, regardless of the amplitude (volume) of the input signal. How is this done? If the output from a cellphone does not have an adjustable volume control, and the EUT may only be used in this manner, then this will be sufficient. Please state if this is the case. It shouldn't be long after we get this response. Have a good day. Regards, Marianne Marianne T. Bosley EMC Admi nistrator 410-354-3300, ext. 412
