netic energy is within the FCC allowable limits

for occupational use, always adhere to the fol-

lowing guidelines:

•DO NOT operate the radio without a proper antenna attached, 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. The radio

is transmitting when the “TX indicator” lights red. You can cause the

radio to transmit by pressing the “PTT” switch.

Electromagnetic Interference/Compatibility

During transmissions, your Icom radio generates RF energy that can

possibly cause interference with other devices or systems. To avoid

such interference, turn off the radio in areas where signs are posted

to do so. DO NOT operate the transmitter in areas that are sensitive

to electromagnetic radiation such as hospitals, aircraft, and blasting

sites.
