OAJATT704FRS/ GMRS + GPS + NOAA Transceiver

– ’ ’ 64 * 80 Resolution FCC WARNING Replacement or substitution of transistors, diodes or other parts of a unique nature, with parts other than those recommended by the manufacturer, may cause a violation of the technical regulations of Part 15 of FCC Rules. SAFETY INFORMATION Your wireless hand-held portable transceiver contains a low power transmitter. When the PTT button is pushed it sends out radio frequency (RF) signals. The device is authorize d to operate at a duty factor not to exceed 50% using alkaline "AAA" size batteries to comply with Federal Communications Commissions (FCC) RF exposure guidelines with safety level guidelines for hand-held wireless devices. Important: To maintain compliance with the FCC’s RF exposure guidelines hold the transmitter at least 1 inch away (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 AT&T supplied belt clip for this product and ensure that the antenna is at least 1 inch (2.5 centimeters) from your body when transmitting. Use only the supplied antenna. Unauthorized antennas, modifications, or attachments could damage the transmitter and may violate FCC regulations. GMRS License: Use of GMRS radios within the United States requires a FCC GMRS licence. An individual 18 years of age or older who is not a representative of a foreign government is eligible to apply for a GMRS system license. You will need two forms from the FCC, FCC form 159 and form 605 Main Form and Schedule F. You can find the forms online at http://www.fcc.gov/formpage.html or call 1-800-418-3676. The FCC requires that you be advised of certain requirements involving the use of this device. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment uses and can generate radio frequency energy, if not installed and used in accordance with the instruction, it may cause harmful interference to radio communications. However, there is no guarantee that the interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception(which can be determined by turning the equipment off and on), the user is encouraged to correct the interference by one of the following measures: 1. Reorient or relocate the receiving antenna. 2. Increase the separation between the equipment and receiver 3. Connect the equipment to an outlet on a circuit different from that to which the receiver is connected. 4. Consult the manufacturer for technical assistance.

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 Page 5 of report. 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 Pages 6,7 & 8 of report. 95.637 Post Limiter Filter Each GMRS transmitter, except a mobile station transmitter with a power of 2.5Watts or less, must be equipped with an audio low pass filter. At any frequency between 3 & 20 kHz the filter must have an attenuation of 60log (f/3) greater than the attenuation at 1KHz. See Page 9 of report. APPLICANT: J COMMUNICA…
