SAFETY TRAINING INFORMATION
Your Icom radio generates RF
electromagnetic energy during
transmit mode. This radio is designed
for and classied as “Occupational
Use Only”, 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” in an uncontrolled environment.
For compliance with FCC and IC RF Exposure
Requirements, the transmitter antenna installation shall
comply with the following three conditions:
1. The transmitter antenna gain shall not exceed 0 dBi.
The antenna is required to be located outside of a
vehicle and kept at a distance of 57 centimeters (23
inches) or more between the transmitting antenna of
this device and any persons during operation. For small
vehicle as worst case, the antenna shall be located on
the roof top at any place on the center line along the
vehicle in order to achieve 57 centimeters (23 inches)
separation distance. In order to ensure this distance is
met, the installation of the antenna must be mounted at
least 57 centimeters (23 inches) away from the nearest
edge of the vehicle in order to protect against exposure
The antenna is required to be located outside of a
vehicle and kept at a distance of 42 centimeters
(17 inches) or more between the transmitting antenna of
this device and any persons during operation. For small
vehicle as worst case, the antenna shall be located on
the roof top at any place on the center line along the
vehicle in order to achieve 42 centimeters (17 inches)
separation distance. In order to ensure this distance is
met, the installation of the antenna must be mounted at
least 42 centimeters (17 inches) away from the nearest
edge of the vehicle in order to protect against exposure
Transmit only when people outside the vehicle are
at least the recommended minimum distance of 136
centimeters (54 inches) away from the properly installed
antenna. This separation distance will ensure that
there is sufcient distance from a properly installed
externally-mounted antenna to satisfy the RF exposure
requirements in the applicable RF exposure compliance
Transmit only when people outside the vehicle are
at least the recommended minimum distance of 119
centimeters (47 inches) away from the properly installed
antenna. This separation distance will ensure that
there is sufcient distance from a properly installed
externally-mounted antenna to satisfy the RF exposure
requirements in the applicable RF exposure compliance
To ensure that your exposure to RF
electromagnetic energy is within the
FCC and IC 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 and IC RF exposure limits. A
proper antenna is the antenna supplied with this radio by
the manufacturer or an antenna specically 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 and IC RF exposure
compliance requirements to be exceeded. The radio is
transmitting when the status 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
If the transceiver becomes dusty or dirty, wipe it clean with
