Circuit Description for Taiyo Kogyo Co., LTD. AEK14349 Q1 is the crystal controlled oscillator. Q2 is the RF amplifier. IC1 is the modulation source which is applied to the base of Q2. The antenna coupling and harmonic suppression components are C6, C7, L3, C8, and L4. Power is supplied via a 9V primary cell battery and regulated down to 5.1 Volts by diode D6. This device has no external ground connectiion and the printed circuit board traces are the only ground connection. The antenna is a permanently attached 9 inch long piece of wire. This is covered by a plastic tube. TAIYO KOGYO CO., LTD. FCC ID: AEKA14349 EXHIBIT #: 10

FCC ID: AEKA14349 REPORT #: T\Taiyo_AEK\200JT2\200JT2RPT.doc PAGE: 1 TEST PROCEDURE GENERAL: This report shall NOT be reproduced except in full without the written approval of TIMCO ENGINEERING, INC. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a prese- lector. The bandwidth of the spectrum analyzer was 100 kHz with an appropriate sweep speed. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The resolution bandwidth was 100 kHz and the video bandwidth was 300 kHz. The ambient temperature of the UUT was 83°C with a humidity of 35%. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was estab- lished by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor sup- plied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the Preselector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) METER READING + ACF = FS 33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m ANSI STANDARD C63.4-1992 10.1.7 MEASUREMENT PROCEDURES: The unit under test was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The table used for radiated measurements is capable of continuous rotation. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1 m to 4 m. The antenna was placed in both the horizontal and vertical planes. APPLICANT: TAIYO KOGYO CO., LTD.

TEST PROCEDURE: The procedure used was ANSI STANDARD C63.4-1992. The spectrum was scanned from 30 MHz to 1000 MHz. When an emission was found, the table was rotated to produce the maximum signal strength. The antenna was placed in both the horizontal and vertical planes and the worse case emissions were reported. The UUT was tested in 3 orthogonal planes. TEST RESULTS: THE UNIT DOES MEET THE FCC REQUIREMENTS. PERFORMED BY: JOSEPH SCOGLIO DATE: MARCH 13, 2002 APPLICANT: TAIYO KOGYO CO., LTD.
