1) Safety Training Information 
Your FM Handheld Transceiver generates RF 
electromagnetic energy during transmit mode. This radio is 
designed for and classified as “Controlled Exposure / 
Occupation Environment”, meaning it must be used only 
during the course of employment by individuals aware of the 
hazards, and the ways to minimize such hazards. This radio 
is NOT intended for use by the “General Population / 
Uncontrolled Environment. 
This radio complies with FCC RF radiation exposure limits 
set forth for a controlled environment. This radio should be 
installed and operated with a minimum distance of 2.5 
centimeters between the radio and your body. Therefore, to 
ensure that your exposure to RF electromagnetic energy is 
within the FCC allowable limits for occupational use, always 
follow below information. 
Do not operate the radio without a proper antenna as this 
may damage the radio and may also cause you to exceed 
FCC RF exposure limits. A proper antenna is the antenna 
supplied with this radio by the manufacturer or an antenna 
specifically authorized by the manufacturer for use with this 
radio. 
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. 
Always use Airtech supplied accessories (antennas, batteries, 
belt clips, speaker/mics, etc.). Use of unauthorized 
accessories can cause the FCC RF exposure compliance 
requirements to be exceeded. 
Always keep the antenna at least 2.5 cm (1 inch) away from 
the body when transmitting and only use the belt-clips, when 
attaching the radio to your belt, etc., to ensure FCC RF 
exposure compliance requirements are not exceeded.
