D FEATURES
❍Built-in DSC meets ITU Class D requirement
An independent receiver continuously watches Ch. 70,
while using another channel. Further, a single antenna
connector allows VHF and Ch. 70 operation, thus sim-
plifying installation. The 10-keypad allows simple and
efficient operation of the DSC emergency functions,
vital for your safety at sea.
❍Superior receiver performance
The IC-M602 has excellent receive specifications of more
than 75 dB for spurious response, and intermodulation
rejection. With such high level performance, received
calls are remarkably clear and free from noise. The pow-
erful audio output from the front facing speaker further
increases the clarity of received calls.
❍Optional COMMANDMIC®
(2 systems are connectable)
The optional COMMANDMIC provides a 2nd and 3rd
station capability and an intercom function. With slim
dimension and sizable LCD, the COMMANDMIC offers
ease and convenience of operating the radio from
remote locations such as the cockpit or tower up to a
max. 21 m* from the IC-M602.
* Requires use of optional OPC-999 extension cables.
❍Large LCD with dot matrix characters
The large dot-matrix display is designed for optimum
readability in any lighting condition. With the extra large
font, the channel number is maximized on the display
and other information can be easily read.
❍Rugged waterproof construction
The IC-M602 including the supplied (HM-136)/optional
(HM-127) microphone has effective waterproofing
equivalent to JIS waterproof grade 7*.
* 1 m/30 min; except cables.

If your vessel requires assistance, contact other vessels and
the Coast Guard by sending a distress call on Channel 16.
Or, transmit your distress call using digital selective calling on
Channel 70.
USING DIGITAL SELECTIVE CALLING (Ch 70)
DISTRESS CALL PROCEDURE
1. While lifting up the switch cover, push and
hold [DISTRESS] for 5 sec. until you hear 5
short beeps change to one long beep.
2. Wait for an acknowledgment on Channel 70
from a coast station.
•After the acknowledgement is received,
Channel 16 is automatically selected.
3. Push and hold [PTT], then transmit the
appropriate information as at left.
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
vessel (AND 9-digit DSC ID if you have one).
4. “LOCATED AT ...............” (your position)
5. The nature of the distress and assistance
required.
6. Any other information which might facilitate
the rescue.
IN CASE OF EMERGENCY

iv
Icom requires the radio operator to meet the
FCC Requirements for Radio Frequency Expo-
sure. An omnidirectional antenna with gain not
greater than 9 dBi must be mounted a minimum
of 5 meters (measured from the lowest point of
the antenna) vertically above the main deck and all possible
personnel. This is the minimum safe separation distance esti-
mated to meet all RF exposure compliance requirements. This
5 meter distance is based on the FCC Safe Maximum Per-
missible Exposure (MPE) distance of 3 meters added to the
height of an adult (2 meters) and is appropriate for all vessels.
For watercraft without suitable structures, the antenna must
be mounted so as to maintain a minimum of 1 meter vertically
between the antenna, (measured from the lowest point of the
antenna), to the heads of all persons AND all persons must
stay outside of the 3 meter MPE radius.
Do not transmit with radio and antenna when persons are
within the MPE radius of the antenna, unless such persons
(such as driver or radio operator) are shielded from antenna
field by a grounded metallic barrier. The MPE Radius is the
minimum distance from the antenna axis that person should
maintain in order to avoid RF exposure higher than the allow-
able MPE level set by FCC.
FAILURE TO OBSERVE THESE LIMITS MAY ALLOW
THOSE WITHIN THE MPE RADIUS TO EXPERIENCE RF
RADIATION ABSORPTION WHICH EXCEEDS THE FCC
MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMIT.
IT IS THE RESPONSIBILITY OF THE RADIO OPERATOR
TO ENSURE THAT THE MAXIMUM PERMISSIBLE EXPO-
SURE LIMITS ARE OBSERVED AT ALL TIMES DURING
RADIO TRANSMISSION. THE RADIO OPERATOR IS TO
ENSURE THAT NO BYSTANDERS COME WITHIN THE
RADIUS OF THE MAXIMUM PERMISSIBLE EXPOSURE
LIMITS.
Determining MPE Radius
THE MAXIMUM PERMISSIBLE EXPOSURE (MPE) RA-
DIUS HAS BEEN ESTIMATED TO BE A RADIUS OF
ABOUT 3M PER OET BULLETIN 65 OF THE FCC.
THIS ESTIMATE IS MADE ASSUMING THE MAXIMUM
POWER OF THE RADIO AND ANTENNAS WITH A MAXI-
MUM GAIN OF 9dBi ARE USED FOR A SHIP MOUNTED
SYSTEM.

RWARNING! NEVER connect the transceiver to an AC
outlet. This may pose a fire hazard or result in an electric
shock.
CAUTION: Changes or modifications to this device, not ex-
pressly approved by Icom Inc., could void your authority to
operate this device under FCC regulations.
NEVER connect the transceiver to a power source of more
than 16 V DC or use reverse polarity. This will ruin the trans-
ceiver.
NEVER cut the DC power cable between the DC plug and
fuse holder. If an incorrect connection is made after cutting,
the transceiver may be damaged.
NEVER place the transceiver where normal operation of the
vessel may be hindered or where it could cause bodily injury.
KEEP the transceiver at least 3.3 ft (1 m) away from the
ship’s navigation compass.
DO NOT use or place the transceiver in areas with temper-
atures below –4°F (–20°C) or above +140°F (+60°C) or, in
areas subject to direct sunlight, such as the dashboard.
AVOID the use of chemical agents such as benzine or al-
cohol when cleaning, as they may damage the transceiver
surfaces.
BE CAREFUL! The transceiver rear panel will become
hot when operating continuously for long periods.
Place the transceiver in a secure place to avoid inadvertent
use by children.
BE CAREFUL! The transceiver and optional HM-127 em-
ploy waterproof construction, which corresponds to JIS wa-
terproof specification, Grade 7 (1 m/30 min.). However, once
the transceiver or microphone has been dropped, water-
proofing cannot be guaranteed due to the fact that the case
may be cracked, or the waterproof seal damaged, etc.

OPERATING RULES
DDPRIORITIES
•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 signals are prohibited and pun-
ishable by law.
DDPRIVACY
• Information overheard but not intended for you cannot law-
fully be used in any way.
• Indecent or profane language is prohibited.
DDRADIO LICENSES
(1) SHIP STATION LICENSE
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 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.
The Restricted Radiotelephone Operator Permit must be
posted or kept with the operator. Only a licensed radio opera-
tor 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.
Keep a copy of the current government rules and regulations
handy.
Radio license for boaters (U.S.A. only)
The Telecommunications Act of 1996 permits recreational
boaters to have and use a VHF marine radio, EPIRB, and
marine radar without having an FCC ship station license.
Boaters traveling on international voyages, having an HF
single sideband radiotelephone or marine satellite terminal,
or required to carry a marine radio under any other regula-
tion must still carry an FCC ship station license. For further
information, see the FCC Ship Radio Stations Fact Sheet.
