FCC ID: MQUST-946A REPORT #: F:S\SHINWOO\SHI330B8.RPT PAGE: TABLE OF CONTENTS SECURITY CODING INFORMATION 15.214(d) - THIS DEVICE COMPLIES WITH THE SECURITY CODE REQUIRE- MENTS OF 15.214(d)(1)(2) AND (3) BY MEANS OF THE FOLLOWING: THIS PHONE IS EQUIPPED WITH A DIGITAL SECURITY SYSTEM WITH OVER 1 MILLION CODE COMBINATIONS. WHEN MAKING A CALL, THE TELEPHONE SEARCHES THROUGH ITS 60 AVAIL- ABLE CHANNELS AUTO CHANNEL SCAN TO FIND THE CLEAEREST ONE. THE RECEIVER PORTION OF THIS TELEPHONE, FCC ID: MQUST-946A, WAS TESTED WITH PASSING RESULTS. A VERIFICATION REPORT HAS BEEN ISSUED PER FCC RULES PART 15.109. TEST EQUIPMENT LIST 1.

Tenney Temperature Chamber 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 preselector. 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 53oF with a humidity of 70%. APPLICANT: SHINWOO TELECOM CO., LTD. FCC ID: MQUST-946A REPORT #: F:S\SHINWOO\SHI330B8.RPT PAGE #: 1 TEST PROCEDURE (CONT) ANSI STANDARD C63.4-1992 10.1.7 MEASUREMENT PROCEDURES: The UUT was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The UUT was placed flush with the back of the table (1.5m side). 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 1m to 4m. The antenna was placed in both the horizontal and vertical planes. The situation was similar for the conducted measurement except that the table did not rotate. The EUT was setup as described in ANSIC63.4-1992 with the EUT 40 cm from the vertical ground wall. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was established by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor supplied by the antenna manufacturer. The antenna correc- tion factors are stated in terms of dB. The gain of the Preselec- tor 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 POWER LINE CONDUCTED INTERFERENCE: The procedure used was ANSI STANDARD C63.4-1992 using a 50uH LISN. Both lines were observed. The bandwidth of the spectrum analyzer was 10kHz with an appropriate sweep speed. The ambient temperature of the UUT was 53oF with a humidity of 70%.

FCC ID: MQUST-946A CIRCUIT_DESCRIPTION: BASE UNIT The incoming signal comes in on the antenna and is fed through the duplexer to the LNA, Q500 and then to a SAW band pass filter,FL501. The frequency range of the base receiver is 925- 928MHz. From the band pass filter the signal is fed to the mixer, Q501 which converts the signal down to 10.7MHz. From Q501 the signal is fed to the IF filter FL501 and then to the integrated circuit U500. In the U500 the signal is converted down to 450KHz and then to the detector for FM signal. From the detector the audio is fed to a low pass filter and to the Channel Detector Indicator. From the low pass f…
