Icom IC-F21S [3/28] Electromagnetic interference compatibility

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.

• ALWAYS use Icom authorized accessories (antennas, batteries,

belt clips, speaker/mics, etc). Use of unauthorized accessories can

cause the FCC RF exposure compliance requirements to be ex-

ceeded.

• ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the

body when transmitting and only use the Icom belt-clips, listed in p. 22,

when attaching the radio to your belt, etc., to ensure FCC RF ex-

posure compliance requirements are not exceeded. To provide the

recipients of your transmission the best sound quality, hold the an-

tenna at least 5 cm (2 inches) from mouth, and slightly off to one

side.

The information listed above provides the user with the information

needed to make him or her aware of RF exposure, and what to do to

assure that this radio operates within the FCC RF exposure limits of this

radio.

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.
