OVCFRS-4000Family Radio

OPERATIONAL DESCRIPTION OF THE 21st CENTURY INNOVATIVE PRODUCTS/HANYANG ELECTRONICS, Ltd. FRS-4000 “WALK & TALK” UHF TWO-WAY RADIO The FRS-4000 “WALK & TALK” is an FM modulated, UHF two-way radio that uses all fourteen frequencies allocated in the FCC part 95, Subpart B, the Family Radio Service (FRS). It is of the “F3E” modulation type that is the only one allowed for the Family Radio Service. These fundamental or carrier frequencies in MHz are: 1: 462.5625 * 8: 467.5625 * 2: 462.5875 9: 467.5875 3: 462.612510: 467.6125 4: 462.637511: 467.6375 5: 462.662512: 467.6625 6: 462.687513: 467.6875 7: 462.7125 *14: 467.7125 * The frequencies marked with an * are examined in detail in this report. They represent the highest and lowest frequencies of two bands. The FRS-4000 uses an integral antenna and has no casual user access for increasing its radiated power or modifying it basic functions. There is no enclosure shielding. The FRS-4000 is powered by 4.5 VDC, supplied by 3 “AAA” alkaline batteries. All measurements in this report used fresh batteries. The authorized bandwidth of the FRS-4000 “WALK & TALK” UHF TWO-WAY RADIO is 12 .5 kHz according to Part 95, section 95.6330. The FCC ID of the FRS-4000 is OVCFRS-4000.

TUNE UP PROCEDURE FROM HANYANG: RX Adjustment: 1. Adjust Signal Generator to 462.5625 MHz at 1 mV. Adjust the FM modulation from 1 kHz to 1.75 kHz. Put this signal into the antenna jack. 2. Connect oscilloscope to number 2 of A>F> Detector at U108 and adjust 1FT101 to obtain maximum DC voltage. 3. Confirm RX sensitivity is below 119 dBm at 462.5625 MHz/12 dB SINAD (SQ OFF Mode). TX Adjust ment: 1. Begin adjustment at 462.5625 MHz for the TX test. 2. Confirm the RX power is no more than 500 mW. 3. Adjust VC101 for precise TX frequency 4. Input 1 kHz signal to MIC JACK terminal and then adjust the maximum frequency differential to 2.2 kHz GENERAL SPECIFICATION OF THE FRS-4000 -See the Instruction Manual exhibit.

FRS-4000 “WALK & TALK” UHF TWO-WAY RADIO, the Equipment U nder Test. The EUT was subjected to the following tests: FCC Part 15, Subpart B, Class B when it is in the receive mode, and FCC Part 95, Subpart B, and FCC Part 2 when it is transmitting. Because the EUT is powered by batteries and does not have a connection to recharge the batteries with AC power, only radiated emission phenomena were examined. Any radiated emissions produced when the FRS-4000 radio is in receive mode are to meet FCC Part 15, Class B requirements. Emissions that appear when the FRS-4000 is transmitting are to meet the requirements of Parts 2 and 95. The Parts 2 and 95 testing also includes measurements of effective radiated power, spurious e missions, occupied bandwidth, and frequency stability under temperature and power voltage variations and audio system characteristics. The FCC ID of the FRS-4000 “WALK & TALK” UHF TWO-WAY RADIO is OVCFRS-4000. The results reported in this document relate only to the unit(s) tested. All testing was performed at the facilities of Global Certification Laboratories, Ltd. East Haddam CT. All test equipment calibration is N.I.S.T. traceable. This report contains detailed descriptions of the test procedures, test data, and a written summary of the results. The report may not be reproduced, except in its entirety, without the permission of Global Certification Laboratories.
