When the PTT button is pushed the transmitter sends out RF signals. The device is authorized to operate at a transmit duty factor not exceeding 50% using alkaline “AAA” size batteries to comply with Federal Communications Commissions (FCC) RF exposure safety level guidelines for hand-held wireless devices. To maintain compliance with the FCC’s RF exposure guidelines, hold the transceiver 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 transceiver on your body using the supplied belt clip, do not transmit with this device in the body worn configuration. Unauthorized antennas, modifications, or attachments could damage the transceiver and may violate FCC regulations. GMRS License : Use of GMRS radios within the United States requires a FCC GMRS license. 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 FCC 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.
