Ope ration is subje ct to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause unde sire d ope ration. Your Midland model FG-2 combines access to FRS (Family Radio Service) channels with operation on GMRS channels. The Family Radio Service is provided for by the FCC and is totally license free. Use of the GMRS channels requires FCC licensing. You can use your FG-2 on the FRS UHF FM band for personal communications at no charge. The FG-2 uses maximum allowable power on FRS for range up to 2 miles. Use for fishing, hunting, picnics, biking, business, or any other activity w here communications are needed for convenience or safety. The model FG-2 operates on 22 channels of FRS and GMRS combined to provide the best in quiet and private communication. Channels 1 through 7 are co-shared by FRS and GMRS users. This means that a person with a FRS unlicensed radio can talk to a person usi…

Alignment instructions WARNING Any repairs or adjustments should be made under the supervision of a qualified radio-telephone technician. TRANSMITTER 1. Power Supply Voltage The Power supply voltage should be set for 4.5 VDC measured at the radio during transmit. Periodically check the power supply voltage during the alignment procedure. 2. Frequency Setting A. Connect a frequency counter or Communications Service Monitor to the antenna connector through an RF power attenuator (10 watt minimum rating, 20 dB minimum attenuation). B. Depress the PTT switch. C. Adjust the CTX1 trimmer capacitor such that the output frequency is equal to the channel frequency with a maximum error of +/- 200 Hz. D. Release the PTT switch. 3. Output Power Alignment. A. Set the power supply voltage for 4.5 VDC. B. Connect a Communications Service Monitor or a wattmeter and dummy load to the antenna connector. C. Depress the PTT switch. D. To be convinced for 0.5 Watt output power with a maximum error of +/- 0.05 Watt. E. Release the PTT switch. 4. Deviation Adjustment. A. Connect an audio generator to the microphone jack JIG. The audio frequency should be set at 1 KHz. B. Connect an FM deviation meter or Communications Service Monitor to the antenna connector through an RF power attenuator (10 watt minimum rating, 20 dB minimum attenuation). Set the monitor to read peak deviation. C. Depress the PTT switch. D. Adjust the audio generator level 100 mV rms. E. Adjust RV3 for +/- 2.4 KHz maximum deviation.(with CTCSS tone) F. To be convinced +/- 1.8KHz without CTCSS tone.(1.2KHz dev. 20dB up) G. Release the PTT switch.

ENGINEERING STATEMENT For Certification of MIDLAND CONSUMER RADIO Model No. FG-2 FCC ID: MMAFG2 I am an Electronics Engineer, a principal in the firm of Hyak Laboratories, Inc., Springfield, Virginia. My education and experience are a matter of record with the Federal Communications Commission. Hyak Laboratories, Inc. has been authorized by Midland Consumer Radio to make certification measurements on the FG-2 transceiver. These tests were made by me or under my supervision in our Springfield laboratory. Test data and documentation required by the FCC for certification are included in this report. The data verifies that the above mentioned transceiver meets FCC requirements and certification is requested. _________________________ Rowland S. Johnson Dated: December 3, 2001 A. INTRODUCTION The following data are submitted in connection with this request for type certification of the FG-2 transceiver in accordance with Part 2, Subpart J of the FCC Rules. The FG-2 is a hand-held, battery operated, UHF, frequency modulated, transceiver intended for voice communications applications under Part 95 GMRS (channels 1-7 or 15-22)* or Part 95 FRS (channels 8-14)*. *See Appendix A for frequency assignment. 1. The unit’s antenna meets 95.647, (i.e. is integral to the transmitter. 2. Except for power, the technical parameters for operating on all the channels (both FRS and GMRS) are the same as those for FRS, (i.e. 12.5 kHz bandwidth, 2.5 ppm frequency tolerance, maximum 2.5 kHz deviation, etc). 3. An informational insert is included inside the box (product package) that clearly informs the consumer (buyer/owner) when the radio is transmitting on GMRS frequencies, that operation on GMRS frequencies requires an FCC license and such operation is subject to additional rules specified in 47 CFR Part 95. (See Appendix B) B. GENERAL INFORMATION REQUIRED FOR TYPE CERTIFICATION (Paragraph 2.983 of the Rules) 1. Name of applicant: Midland Consumer Radio 2. Identification of equipment: FCC ID: MMAFG2 a. The equipment identification label is submitted as a separate exhibit. b. Photographs of the equipment are submitted as separate exhibits. 3. Quantity production is planned. 4. Technical description: a. 11k0F3E emission (FRS and GMRS) b. Frequency range: 462.5500-467.7125 MHz. c. Operating power ERP(d): FRS 0.410 W GMRS 0.492 W 2 B. GENERAL INFORMATION (Cont.) d. Maximum power permitted under FCC Part 95 (interstitial) is 5 watts ERP. The FG-2 fully complied with that power limitation. e. The dc voltage and dc currents at final amplifier: GMRS FRS Collector voltage: 4.4 4.4 Vdc Collector current: 0.69 0.62 A f. Function of each active semiconductor device: See Appendix 1. g. Complete circuit diagram is submitted as a separate exhibit. h. A draft instruction book is submitted as a separate exhibit. i. The transmitter tune-up procedure is submitted as a separate exhibit. j. A description of circuits for stabilizing frequency is included in Appendix 2. k. A description of circuits and devices employed for suppression of spurious radiation and for limiting modulation is included in Appendix 3. l. Not applicable. 5. Data for 2.985 through 2.997 follow this section. C. RF POWER OUTPUT (Paragraph 2.985(a) of the Rules) ERP(d) by substitution: FRS 0.410 W GMRS 0.492 W D. MODULATION CHARACTERISTICS 1. A curve showing frequency response of the transmitter is shown in Figure 1. Reference level was audio signal output from a Boonton 8220 modulation meter with one kHz deviation. Audio output was measured with an Audio Precision System One TRMS voltmeter and tracking generator. 2. Modulation limiting curves are shown in Figure 2, using a Boonton 8220 modulation meter. Signal level was established with an Audio Precision System One. The curves show compliance with paragraphs 2.987(b) and 95.633(b). 3 D. MODULATION CHARACTERISTICS (Cont.) 3. Figure 3 is a graph of the post-limiter low pass filter which meets the requirements of paragraph 95.633(b) in providing a roll-off of 60Logf/3 dB where f is audio frequency in kHz. Measurements were made following EIA RS-152B with an Audio Precision System One on the Boonton 8220 modulation meter audio output. 4. Occupied_Bandwidth (Paragraphs 2.989(c), 90.209(b)(4), and 95.629(a) of the Rules) Figure 4a is a plot of the sideband envelope of the transmitter output taken with a Tektronix 494P spectrum analyzer on GMRS Channel 1. Modulation corresponded to conditions of 2.989(c)(1) and consisted of 2500 Hz tone at an input level 16 dB greater than that necessary to produce 50% modulation at 2891 Hz, the frequency of maximum response. Figure 4b is a plot under the same conditions for FRS Channel 8. The plots are within the limits imposed by Part 95 for frequency modulation. The horizontal scale (frequency) is 10 kHz per division and the vertical scale (amplitude) is a logarithmic presentation equal to 10 dB per division. 5.
