INSTALLATION NOTE
Installation:
The installation of this equipment should be made in such a
manner as to respect the EC recommended electromagnetic
eld exposure limits. (1999/519/EC)
The maximum RF power available from this device is 25
watts. The antenna should be installed as high as possible
for maximum efciency and the installation height should be
at least 1.76 meters above any accessible position. In the
case where an antenna cannot be installed at a reasonable
height, then the transmitter should neither be continuously
operated for long periods if any person is within a distance
of 1.76 meters of the antenna, nor operated at all if any
person is touching the antenna.
It is recommended that antenna of a maximum gain of
3 dB is used. If higher gain antenna are required then
please contact your Icom distributor for revised installation
recommendations.
Operation:
The exposure to RF electromagnetic eld is only applicable
when this device is transmitting. This exposure is naturally
reduced due to the nature of alternating periods of receiving
and transmitting. Keep your transmissions to the minimum
necessary.

PRECAUTIONS
RWARNING! NEVER
connect the transceiver to an AC outlet. This
may pose a re hazard or result in an electric shock.
RWARNING! NEVER connect the transceiver to an external DC
power supply directly. The transceiver should be connected to the
DC power supply through the PS-310 that is sold by the set with this
transceiver. Be sure to not connect with reverse polarity.
PS-310’s version Input voltage Output voltage
#01 21.6 ~ 31.2 V DC 12.6 V DC
#02 10.8 ~ 15.6 V DC 12.6 V DC
RWARNING! NEVER cut the DC power cable between the DC
plug at the back of the transceiver and fuse holder. If an incorrect
connection is made after cutting, the transceiver may be damaged.
RWARNING! NEVER operate the transceiver during a lightning
storm. It may result in an electric shock, cause a re or damage the
transceiver. Always disconnect the power souce and antenna before
a storm.
CAUTION: NEVER
place the transceiver where normal operation of
the vessel may be hindered, or where it could cause bodily injury.
KEEP the transceiver and microphone at least 1 m away from the
vessel’s magnetic navigation compass.
DO NOT place or leave the transceiver in areas with temperatures
below –15°C or above +55°C, or in areas subject to direct sunlight,
such as a dashboard.
DO NOT use harsh solvents such as benzine or alcohol to clean the
transceiver, as they will damage the transceiver’s surfaces. If the
transceiver becomes dusty or dirty, wipe it clean with a soft, dry cloth.
BE CAREFUL! The transceiver rear panel will become hot when
operating continuously for long periods of time.
Place the transceiver in a secure place to avoid inadvertent use by
children.
BE CAREFUL! The transceiver’s front panel meets IPX7*
requirements for waterproof protection. However, once the front
panel has been dropped, or the waterproof seal is cracked or
damaged, waterproof protection cannot be guaranteed because of
possible damage to the case or the waterproof seal.
*The connectors on the rear panel do not meet IPX7.
If the front panel is exposed to saltwater, BE SURE TO CLEAN
IT THOROUGHLY WITH FRESH WATER when the front panel's
waterproof protection is effective. Otherwise, the keys and switch
may become inoperable due to salt crystallization.
Icom is not responsible for the destruction or damage to the Icom
transceiver, if the malfunction is because of:
• Force majeure, including, but not limited to, res, earthquakes,
storms, oods, lightnings, or other natural disasters,
disturbances, riots, war, or radioactive contamination.
• The use of Icom transceiver with any equipment that is not
manufactured or approved by Icom.

OPERATING RULES
1
DPriorities
• Read all rules and regulations pertaining to call priorities,
and keep an up-to-date copy handy. Safety and distress
calls take priority over all others.
• You must monitor Channel 16 when you are not operating
on another channel.
• False or fraudulent distress calls are prohibited under law.
DPrivacy
• Information overheard, but not intended for you, cannot
lawfully be used in any way.
• Indecent or profane language is prohibited.
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
government agency for a Ship-Radiotelephone license
application. This government-issued license states the call
sign which is your craft’s identication 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
regulations 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 regulations.
