Your Icom radio generates RF electromagnetic energy during
transmit mode.
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 fol-
lowing 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 Electro-
magnetic Fields.
• American National Standards Institute (C95.1-1992), IEEE Standard for
Safety Levels with Respect to Human Exposure to Radio Frequency Elec-
tromagnetic 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 (MB-
86, MB-103), Rechargeable Li-Ion Battery Pack (BP-245N), Speaker-mi-
crophone (HM-125), Headset with headset adapter (HS-94, HS-95, HS-97
with OPC-1392).
C AU T IO N
To ensure that your expose to RF electromagnetic en-
ergy is within the FCC allowable limits for occupational
use, always adhere to the following guidelines:
•
DO NOT operate the radio without a proper antenna attached, as this may
damaged the radio and may exceed FCC RF exposure limits. A proper
antenna is the antenna supplied with this radio by the manufacturer or
an 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 expo-
sure compliance requirements to be exceeded. The radio is transmitting
when the “TX indicator” lights. When the radio is turned ON, pressing the
“PTT” switch makes the radio transmit.
•
ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body
when transmitting and only use one of the belt clips 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 radio in an almost verti-
cal position at least 5 cm (2 inches) from your mouth. The microphone is
located next to the speaker, so you should “talk into the speaker”.
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 within FCC RF exposure limits.
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.
SAFETY TRAINING INFORMATION

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. Say your call sign or other indication of the
vessel.
4. “LOCATED AT ..................... ” (your position)
5. State the nature of the distress and assis-
tance required.
6. Give any other information which might facili-
tate the rescue.
RECOMMENDATION
CLEAN THE TRANSCEIVER THOROUGHLY WITH FRESH
WATER after exposure to saltwater, and dry it before opera-
tion. Otherwise, the transceiver’s keys, switches and control-
lers may become inoperable due to salt crystallization.
NOTE: DO NOT wash the transceiver in water if there is any
reason to suspect the waterproofing may not be effective. For
example, in cases where the transceiver/battery pack is cracked
or broken, or has been dropped, or when the battery pack is
detached from the transceiver.

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 closer than 2.5 cm (1 inch) from 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
(2 to 4 inches) away from the lips and the transceiver is verti-
cal.
NEVER connect the transceiver to a power source other
than the BP-245N. Such a connection will ruin the trans-
ceiver.
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 0.9 meters (3.0 ft) away from
your vessel’s magnetic navigation compass.
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 in-
side of the transceiver to water will result in serious damage
to the transceiver.
BE CAREFUL! The IC-M72 employs submersible con-
struction (1.5 m; 4.9 ft depth for 30 min.). However, once the
transceiver has been dropped, waterproofing cannot be guar-
anteed due to the fact that the transceiver may be cracked, or
the waterproof seal damaged, etc.
For the U.S.A. only
CAUTION: Changes or modifications to this device, not
expressly approved by Icom Inc., could void your authority to
operate this device under FCC regulations.

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 regula-
tions.
NOTE: Even though the IC-M72 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.
