WORD DEFINITION
RWARNING Personal injury, fire hazard or electric shock
may occur.
CAUTION Equipment damage may occur.
NOTE If disregarded, inconvenience only. No risk
of personal injury, fire or electric shock.
After exposure to saltwater, clean the transceiver thor-
oughly with fresh water to avoid corrosion.

iii
CAUTIONS
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
antenna is very close to, or touching exposed parts of the
body, especially the face or eyes, while transmitting. The
transceiver will perform best if the microphone is 5 to 10 cm
away from the lips and the transceiver is vertical.
NEVER connect the transceiver to a power source other
than the BP-223 or BP-224. Such a connection will ruin the
transceiver.
AVOID using or placing the transceiver in direct sunlight or
in areas with temperatures below –20°C (–4°F) or above
+60°C (+140°F).
KEEP the transceiver out of the reach of children.
KEEP the transceiver at least 1 meter away from your ves-
sel’s magnetic navigation compass.
BE CAREFUL! The transceiver rear panel will become
hot when operating continuously for long periods.
BE CAREFUL! The IC-M2A employs waterproof con-
struction, which corresponds to JIS waterproof specification,
grade 7 (1 m/ 30 min.). However, once the transceiver has
been droped, waterproofing cannot be guaranteed due to the
fact that the transceiver may be cracked, or the waterproof
seal damaged, etc.
MAKE SURE the flexible antenna and battery 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.
KEEP the transceiver at least 1 m (3.3 ft) away from the
ship’s navigation compass.
KEEP the transceiver out of the reach of children.
For U.S.A. only
CAUTION: Charges or modifications to this device, not
expressly approved by Icom Inc., could void your authority to
operate this device under FCC regulations.

SAFTY TRAINING INFORMATION
Your Icom radio generates RF electromagnetic
energy during transmit mode. This radio is de-
signed 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 NOT intended for use by the “General Popula-
tion” in an uncontrolled environment.
This radio has been tested and complies with the FCC RF exposure
limits for “Occupational Use Only”. In addition, your Icom radio com-
plies with the following Standards and Guidelines with regard to RF
energy and electromagnetic energy levels and evalution of such lev-
els 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 Stan-
dard 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 Rec-
ommended Practice for the Measurement of Potentially Haz-
ardous Electromagnetic Fields– RF and Microwave.
WARNING
To ensure that your expose to RF electro-
magnetic energy is within the FCC allowable
limits for occupational use, always adhere
to the foliowing guidelines:
• DO NOT operate the radio without a proper antenna attached,
as this may damaged the radio and may also cause you to ex-
ceed FCC RF exposure limits. A proper antenna is the antenna
supplied with this radio by the manufacturer or antenna specifi-
cally 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 ex-
ceeded. The radio is transmitting when the “TX indicator” lights
red. You can cause the radio to transmit by pressing the “PTT”
switch.
• ALWAYS use Icom authorized accessories (antennas, batteries,
belt clips, speaker/mics, etc). Use of unauthorized accessories
can cause the FCC RF exposure compliance requirements to be
exceeded.
CAUTION

v
IN CASE OF EMERGENCY
If your vessel requires assistance, contact other vessels and
the Coast Guard by sending a distress call on channel 16.
❍ USING CHANNEL 16
DISTRESS CALL PROCEDURE
1. “MAYDAY MAYDAY MAYDAY.”
2. “THIS IS ...........................” (name of vessel)
3. Your call sign or other indication of the ves-
sel.
4. “LOCATED AT .....................” (your position)
5. The nature of the distress and assistance re-
quired.
6. Any other information which might facilitate
the rescue.
• 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 listed in page 25 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
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
possiibly 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.

OPERATING RULES
DPriorities
• Read all rules and regulations pertaining to 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 law-
fully be used in any way.
• Indecent or profane language is prohibited.
DRadio licenses
(1) SHIP STATION LICENSE
When your craft is equipped with a VHF FM transceiver, you
must have a current radio station license before using the
transceiver. It is unlawful to operate a ship station which is not
licensed.
Inquire through your dealer or the appropriate government
agency for a Ship-Radiotelephone license. This license in-
cludes 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.
The Restricted Radiotelephone Operator Permit must be
posted near the transceiver or be kept with the operator. 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 regulations.
NOTE: Even though the IC-M2A is capable of operation
on VHF marine channels 3, 21, 23, 61, 64, 81, 82 and 83,
according to FCC regulations these simplex channels can-
not be lawfully used by the general public in USA waters.
