RDANGER! NEVER short the terminals of the battery
pack.
RDANGER! Use and charge only specified Icom battery
packs with Icom radios or Icom chargers.Only Icom battery packs
are tested and approved for use with Icom radios or charged with
Icom chargers. Using third-party or counterfeit battery packs or
chargers may cause smoke, fire, or cause the battery to burst.
RWARNING! NEVER connect the transceiver to an AC
outlet. This may pose a fire hazard or result in an electric shock.
RWARNING! NEVER hold the transceiver so that the an-
tenna is closer than 2.5 cm (1 inch) from exposed parts of the
body, especially the face or eyes, while transmitting. The trans-
ceiver will perform best if the microphone is 5 to 10 cm (2 to 4
inches) away from the lips and the transceiver is vertical.
CAUTION: NEVER connect the transceiver to a power
source other than the products specified by Icom. Such a connec-
tion will ruin the transceiver.
CAUTION: MAKE SURE the flexible antenna and bat-
tery pack are securely attached to the transceiver, and that the
antenna and battery pack are dry before attachment. Exposing
the inside of the transceiver to water will result in serious damage
to the transceiver.
BE CAREFUL! The transceiver meets IPX8 requirements
for waterproof protection. However, once the transceiver has
been dropped, waterproof protection cannot be guaranteed be-
cause of possible damage to the transceiver's case or the water-
proof seal.

transmit mode. This radio is designed for and classified as
“General Population Use” in an uncontrolled environment.
This radio has been evaluated for compliance at the distance
of 2.5 cm (1 inch) with the FCC and IC RF exposure limits for
“
General Population Use. ” In addition, your Icom radio com-
plies with the following Standards and Guidelines with regard
to RF energy and electromagnetic energy levels and evalua-
tion of such levels for exposure to humans:
• FCC OET Bulletin 65 Edition 01-01 Supplement C, Evaluating Compli-
ance 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 Recom-
mended Practice for the Measurement of Potentially Hazardous Electro-

population use, always adhere to the following guide-
lines:
• DO NOT operate the radio without a proper antenna attached, as this
may damaged 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 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
and IC
RF exposure compliance requirements to be exceeded. The radio is
transmitting when the “transmit indicator” appears on the LCD. 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 clip which is listed on page
43 when attaching the radio to your belt, etc., to ensure FCC
and IC RF
exposure compliance requirements are not exceeded. To provide the re-
cipients 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
and IC 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.

DRadio licenses
(1) SHIP STATION LICENSE
You may require a current radio station license before using
the transceiver. It is unlawful to operate a ship station which is
not licensed, but required to be.
If required, contact your dealer or the appropriate govern-
ment agency for a Ship-Radiotelephone license application.
This government-issued license states the call sign which is
your craft’s identification for radio purposes.
(2) OPERATOR’S LICENSE
A Restricted Radiotelephone Operator Permit is the license
most often held by small vessel radio operators when a radio
is not required for safety purposes.
If required, the Restricted Radiotelephone Operator Permit
must be posted or kept with the operator. If required, only a
licensed radio operator may operate a transceiver.
However, non-licensed individuals may talk over a transceiver
if a licensed operator starts, supervises, ends the call and
makes the necessary log entries.
A current copy of the applicable government rules and regu-
lations is only required to be on hand for vessels in which
a radio telephone is compulsory. However, even if you are
not required to have these on hand it is your responsibility to
be thoroughly acquainted with all pertinent rules and regula-
tions.
NOTE: Even though the transceiver is capable of opera-
tion on VHF marine channels 3, 21, 23, 61, 64, 81, 82 and
83, according to FCC regulations these simplex channels
cannot be lawfully used by the general population in USA
waters.
