- CAUTION! -
IMPORTANT SAFETY INFORMATION
Your wireless transceiver contains a radio frequency transmitter. When the PTT
button is pushed the transmitter sends out RF signals.
CAUTION: To comply with FCC RF exposure compliance requirements, a separation
distance of at least 8 inches (20 cm) must be maintained between the antenna of this
transmitter and all persons, during normal operation. The antenna used for this

transmitter. Unauthorized antennas, modifications, or attachments could damage the
transceiver and may violate FCC regulations.
CAUTION: DO NOT transmit for more than 50% of total radio use time (50% duty
cycle). Transmitting more than 50% of the time can cause FCC RF exposure
compliance requirements to be exceeded.
Failure to observe these restrictions is in violation with the FCC rules.
GMRS License :
Use of GMRS radios within the United States requires a FCC GMRS license. An
