[RF EXPOSURE STATEMENT : PDHGMRS120 / TTI TECH CO., LTD.] - CAUTION! - IMPORTANT SAFETY INFORMATION Your wireless hand-held portable transceiver contains a radio frequency transmitter. 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. This device has been tested for SAR (SPECIFIC ABSORBTION RATE) and has been found to meet the requirements for body-worn transceiver. If you wear the radio, always use the manufacturer-supplied belt clip. Use of non-manufacturer-approved accessories may exceed the FCC RF exposure guidelines. 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. Unauthorized antennas, m odifications, or attachments could damage the transceiver and may violate FCC regulations. GMRS License : Use of GRMS radios within the United States requires a FCC GMRS license.
