1 OWNER’S MANUAL GMRS/FRS RADIO 21-1904 June 11, 2003 INTRODUCTION Your GMRS/FRS radio is a portable, easy-to-use, two-way radio that you can carry almost anywhere. Use it to contact family and friends at shopping malls, amusement parks, sports events, or at the beach to, or for making vital communications in a neighborhood watch. Your radio has 22 GMRS/FRS channels, 38 CTCSS codes and 10 NOAA weather channels. If someone else is using the same channel as you selected but you do not want to hear that person, select another channel or use the CTCSS feature. You can talk with a person who has a GMRS/FRS radio if both radios are tuned to the same channel and CTCSS code. Your radio has auto-squelch, which means you will not hear anything on a channel unless someone is transmitting nearby the same channel. You can turn off auto-squelch to hear weaker and more distant transmissions. Also, if the radio is idle for 30, 60 or 90 minutes, it will automatically shut off. It can be wakened up when you press any key. You can connect an optional speaker/microphone and earphone, charger (not supplied) to the radio. In addition, the belt clip on the back of the radio makes you take it very conveniently, you can carry it almost anywhere. FCC INFORMATION Caution: This two-way radio operates on GMRS (General Mobile Radio Service) frequencies which require an FCC (Federal Communications Commission) license. A user must be licensed prior to operating on channels 1 through 7 or 15 through 22, which comprise the GMRS channels of this radio. Serious penalties could result for unlicensed use of GMRS channels, in violation of FCC rules, as stipulated in the Communications Act’s Sections 501 and 502. For licensing information and application forms, please call the FCC Hotline at 800-418-FORM. Request form #159 and form #605. Questions regarding the license application should be directed to the FCC at 888-CALL-FCC. Additional information is available on the FCC’s website at www.fcc.gov. Do not open your radio to make any internal adjustments. Your radio is set up to transmit a regulated signal on one of 22 assigned frequencies. It is against the law to alter or adjust the settings inside the radio to exceed those limitations. Any adjustments for your radio can only be made by a qualified technician via using the proper test equipment. 2 To be safe and sure: ! Never open your radio’s case. ! Never change or replace anything in your radio except the batteries. Your radio might cause interference with TV or radio even if it is being operated properly. To determine whether your radio is causing the interference, you’d better turn it off. If the interference goes away, your radio is causing it. You can try to eliminate the interference by: ! moving your radio away from the receiver ! calling your local RadioShack store for help If you cannot eliminate the interference, the FCC requires that you stop using the radio. This device complies with Part 15 of the FCC Rules. Operation is subject 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 undesired operation. SAFETY INFORMATION Your wireless hand-held portable transceiver contains a low power transmitter. When the Push-to-Talk button is pushed, it will send out radio frequency (RF) signals. The device is authorized to operate at a duty factor not to exceed 50%. In August 1996, the Federal Communications Commissions (FCC) adopted RF exposure guidelines with safety levels for hand-held wireless devices. CAUTION: To maintain compliance with the FCC’s RF exposure guidelines, you should hold the transmitter and antenna at least 2 inch (5 centimeters) from your face and speak in normal voice, with the antenna pointed up and away from the face. If you wear the handset on your body while using the headset accessory, only the supplied belt clip for this product can be used, and when transmitting, take it out of the belt to ensure that the antenna is at least 1 inch (2.5 centimeters) from you body. Only the supplied antenna can be used, any unauthorized antennas, modifications, or attachments could damage the transmitter and may violate FCC regulations. LCD DISPLAY : Your radio is designed to have a multifunctional backlight display. By pressing any button except the CALL and PTT, the backlight will illuminate for 5 seconds. 3 1.

With a nominal battery voltage of 6.0 V, and the transmitter properly adjusted the RF output measures: GMRS HI: 0.832 Watts ERP GMRS LO: 0.457 Watts ERP FRS: 0.457 Watts ERP 2.1033(c)(6)(7) Power Output shall not exceed 0.50 Watts effective 95.639 radiated power. There can be no provisions for 95.649 increasing the power or varying the power. 2.1033(c)(8) DC Voltages and Current into Final Amplifier: FINAL AMPLIFIER ONLY FOR LOW POWER SETTING INPUT POWER: (6.0V)(.450A) = 2.70 Watts FOR HIGH POWER SETTING INPUT POWER: (6.0V)(.750A) = 4.50 Watts 2.1033(c)(9) Tune-up procedure. The tune-up procedure is included as EXHIBIT # 8. 2.1033(c)(10) Complete Circuit Diagrams: The circuit diagram is included as EXHIBIT 5 of this report. The block diagrams are included as EXHIBIT 4 of this report. 2.1033(c)(11) A photograph or a drawing of the equipment identification label is included as EXHIBIT 1. 2.1033(c)(12) Photographs(8"X10") of the equipment of sufficient clarity to reveal equipment construction and layout, including meters, labels for controls, including any view under shields.

The audio frequency response curve is shown on the next page. The audio signal was fed into a dummy microphone circuit and into the microphone connector. The input required to produce 30 percent modulation level was measured. See plot below.
