Icom IF1721/D Instruction Manual page 37

To ensure that your exposure to RF electromag-
netic energy is within the FCC allowable limits
for occupational use, always adhere to the fol-
lowing guidelines:
C AU TIO N
• 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.
