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 89oF with a humidity of 80%. APPLICANT: MIPRO ELECTRONICS CO. LTD. FCC ID: M5XMH-801 DATE: 15 July 1999 REPORT #: F:\CUS\M\MIPRO\MIP241T9\MIP241T9RPT.DOC 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 89oF with a humidity of 80%.

FCC ID: M5XMH-801 CIRCUIT DESCRIPTION: The incoming signal comes in on the antenna and is fed through the duplexer to the LNA, Q500 and then to a SAW bandpass filter,FL501. The frequency rang of the base receiver is 926- 928MHz. From the bandpass filter the signal is fed to the mixer, Q501 which converts the signal down to 26.05MHz. From Q501 the signal is fed to the IF filter FL502 and then to the intergrated 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 filter the audio is fed into another low pass filter and shaper and then to the CPU, U311. From the CPU, U311, the audio is fed to a speaker amplifier and the tele- phone line depending which is selected. From the CPU the line audio is fed to U305A and then to U305B then to the telephone coupling transformer, T301. The CPU also comparies the SECURTY CODES and provides the outgoing SECURITY CODE. On the transmitting side, when a ring signal is detected the transmitter is turned on by photo complier integrated circuit U301 and the ring detect signal is fed into the CPU, U306, which in turn triggers the transmitter and send a ring signal to the handset. The base transmit frequency range is 902-904MHz. When the handset answers the base unit connects to the phone line and telephone line audio is fed into the speech network and then to an audio amplifier, Q30…
