SAFETY TRAINING INFORMATION
W ARNING
Your Icom radio generates RF electro-
magnetic energy during transmit
mode. This radio is designed for and
classified as “Occupational Use Only,”
meaning it must be used only during
the course of employment by individu-
als aware of the hazards, and the ways
to minimize such hazards.
This radio is NOT intended for use by
the “General Population” in an uncon-
trolled environment.

CAU TION
To ensure that your exposure to RF
electromagnetic energy is within the
FCC allowable limits for occupational
use, always adhere to the following
guidelines:
FCC allowable limits for occupational
use, always adhere to the following
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 ra-
dio.

•
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 com-
pliance 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.

FOR CLASS B UNINTENTIONAL RADIATORS
This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and
can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harm-
ful interference to radio communications. However, there is
no guarantee that interference will not occur in a particular
installation.
