TIMCO ENGINEERING INC. 849 NW State Road 45 Newberry, Florida 32669 http://www.timcoengr.com 888.472.2424 F 352.472.2030 email: [email protected] 7/15/2000 Ms. Katie Hawkins FCC SUBJECT: FCCID: BGAFR560 REFERENCE: EA97864 With reference to your email of 7/12/00; 1. You are correct, this UUT does not have any adjustments, it is only a verification of power output. 2. This was a typographic error and the power output should be 360mW. 3. The maximum duty factor is 50%. 4. There is a clip-on speaker-mic available for this device. When worn on the belt, the separation distance is LESS than 1 inch (2.5 cm). Please refer to the revised RF exposure safety statement. 5. Also uploaded at this time is a revised RF exposure safety statement to be included in the users manual. If you have any questions please let me know. Sincerely, Sid Sanders email:[email protected]

Safety Information For FRS UNIT Your wireless handheld portable transceiver contains a low power transmitter. When the PTT button is pushed it sends out radio frequency (RF) signals. This device is authorized to operate at a duty factor not to exceed 50%. In August 1996, the Federal Communications Commission (FCC) adopted RF exposure guidelines with safety levels for hand-held wireless devices. Important: To maintain compliance with the FCC’ s RF exposure guidelines, hold the transmitter at least 1 inch (2.5 centimeters) from your face and speak in a normal voice, with the antenna pointed up and away. If you wear the handset on your body while using the headset accessory, use only the AUDIOVOX supplied belt clip for this product and ensure that the antenna is at least 1 inch (2.5 centimeters) from your body when transmitting. If the distance between the antenna and the body is LESS THAN 1.0”(2.5cm ), DO NOT USE THIS DEVICE IN THE BODY WORN CONFIGURATION . Use only the supplied antenna. Unauthorized antennas, modifications, or attachments could damage the transmitter and may violate FCC regulations. Normal Position: Hold the transmitter approximately 1” from your face and speak in a normal voice, with the antenna pointed up and away.

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 EXHIBIT #: 9. 2.1047(b) Audio input versus modulation The audio input level needed for a particular per- percentage of modulation was measured in accor- dance with TIA/EIA Specification 603. The audio input curves versus modulation are on the following pages. Curves are provided for audio input frequen- cies of 300, 1000, and 3000 Hz. See EXHIBIT # 10A-10C. 95.635(b) Post Limiter Filter The filter must be between the modulation limiter and the modulated stage. At any frequency between 3 & 20KHz the filter must have an attenuation of 60log (f/3) greater tha the attenuation at 1KHz.
