SAFETY TRAINING INFORMATION
Your Icom radio generates RF electromagnetic 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 individuals aware of the hazards, and the ways to minimize such hazards. This radio is
W ARN ING
NOT intended for use by the “General Population” in an uncontrolled environment.
This radio has been evaluated for compliance at the distance of 2.5 cm with
the FCC RF exposure limits for “Occupational Use Only”. In addition, your Icom
radio complies with the following Standards and Guidelines with regard to RF
energy and electromagnetic energy levels and evaluation of such levels for exposure to humans:
• FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance
with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.
• American National Standards Institute (C95.1-1992), IEEE Standard for
Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.
• American National Standards Institute (C95.3-1992), IEEE Recommended
Practice for the Measurement of Potentially Hazardous Electromagnetic
Fields– RF and Microwave.
• The following accessories are authorized for use with this product. Use of
accessories other than those specified may result in RF exposure levels
exceeding the FCC requirements for wireless RF exposure.; Belt Clip (MB86/103), Rechargeable Ni-Cd Battery Pack (BP-225) and Alkaline Battery
Case (BP-223).
To ensure that your expose to RF electromagnetic energy is within the FCC allowable limits for occupational
use, always adhere to the following guidelines:
C AU TIO N
• DO NOT operate the radio without a proper antenna attached, as this may
damaged 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 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 keep the antenna at least 2.5 cm (1 inch) away from the body
when transmitting and only use the Icom belt-clips which are listed on
page 33 when attaching the radio to your belt, etc., to ensure FCC RF exposure compliance requirements are not exceeded. To provide the recipients of your transmission the best sound quality, hold the antenna at least
5 cm (2 inches) from your 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 with 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.
Occupational/Controlled Use
The radio transmitter is used in situations in which persons are exposed as
consequence of their employment provided those persons are fully aware of
the potential for exposure and can exercise control over their exposure.

wide frequency range. The transceiver has priority scan and
normal scan.
In addition, the “Weather alert” and “Auto scan” functions are
available for standby convenience. These functions can be
activated simultaneously, depending on the settings on the
SET mode. (pgs. 17, 18)

insert battery pack/transceiver
(with the battery pack attached) with wet or soiled into the
charger. This may result in corrosion of the charger terminals
or damage to the charger. The charger is not waterproof and
water can easily get into it.
NEVER incinerate used battery packs. Internal battery gas
may cause an explosion.
NEVER immerse battery pack in water. If the battery pack
becomes wet, be sure to wipe it dry immediately (particularly
the battery terminals BEFORE attaching it to the transceiver.
NEVER short the terminals of the battery pack. Also, current may flow into nearby metal objects, such as a necklace,
etc. Therefore, be careful when carrying with, or placing near
metal objects, carrying in handbags, etc.
If your battery pack seem to have no capacity even after
being charged, completely discharge them by leaving the
power ON overnight. Then, fully charge the battery pack
again. If the batteries still do not retain a charge (or very little),
new battery pack must be purchased.
Turn power OFF the transceiver when charging the battery
pack with the transceiver. Otherwise, the battery pack may
not become full-charging or may not charge properly.
