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 100KHz and the video bandwidth was 300KHz. The ambient temperature of the UUT was 89º with a humidity of 59%. APPLICANT: YICK SHUN ELECT. TOYS MFG.

LTD FCC ID: J7IER373A TEST PROCEDURES CONTINUED 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 APPLICANT: YICK SHUN ELECT. TOYS MFG.

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 : JUNE 18, 2001 APPLICANT: YICK SHUN ELECT. TOYS MFG.

LTD FCC ID: J7IER373A NAME OF TEST: Occupied Bandwidth RULES PART NO.: 15.227 REQUIREMENTS: The field strength of any emissions appearing outside the 26.96-27.28 MHz band shall not exceed the general radiated emission limits in (15.209). THE GRAPH IN PAGE 5 REPRESENTS THE WORSE CASE OCCUPPIED BANDWIDTH EMISSIONS FOR THIS DEVICE. METHOD OF MEASUREMENT: A small sample of the transmitter output was fed into the spectrum analyzer and the attached plot was taken. The vertical scale is set to -10 dBm per division. The horizontal scale is set to 5 kHz per division. TEST RESULTS: The unit DOES meet the FCC requirements. PERFORMED BY: JOE SCOGLIO DATE : JUNE 18, 2001 APPLICANT: YICK SHUN ELECT. TOYS MFG.
