CAUTIONS
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 transceiver.
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
vehicle 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*
employ waterproof construction, which corresponds to JIS
waterproof specification, grade 7 (1 m/30 min.). However,
once the transceiver or microphone has been dropped, waterproofing cannot be guaranteed due to the fact that the case
may be cracked, or the waterproof seal damaged, etc.

RADIO OPERATOR WARNING
WARNING
iv
Icom requires the radio operator to meet the
FCC Requirements for Radio Frequency Exposure.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 estimated to meet all RF exposure compliance requirements.
This 5 meter distance is based on the FCC Safe Maximum
Permissible 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 allowable 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 EXPOSURE 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) RADIUS 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 MAXIMUM GAIN OF 9dBi ARE USED FOR A SHIP MOUNTED
SYSTEM.

OPERATING RULES
■ Channel selection
ïï
PRIORITIES
•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 should monitor Ch 16 when you are not operating on another
channel.
•False or fraudulent distress signals are prohibited and punishable
by law.
ïï
PRIVACY
•Information overheard but not intended for you cannot law-fully be
used in any way.
•Indecent or profane language is prohibited.
ïï
RADIO LICENSES
(1) SHIP STATION LICENSE
In some countries, you must have a current radio station license before using the transceiver.
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.
1
(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.
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 travelling on international voyages, having an HF
single sideband radiotelephone or marine satellite terminal,
or required to carry a marine radio under any other regulation must still carry an FCC ship station license. For further
information, see the FCC Ship Radio Stations Fact Sheet.

Scanning is an efficient way to locate signals quickly over a
wide frequency range. The transceiver has priority scan and
normal scan.
When the weather alert function is in use, the selected
weather channel is checked while scanning. (p. 20)
PRIORITY SCAN
CH 01
CH 06
CH 05 CH 04
Priority scan searches through all tag channels in sequence while monitoring Ch 16. When a signal is detected
on Ch 16, scan pauses until the signal disappears; when a
signal is detected on a channel other than Ch 16, scan becomes dualwatch until the signal disappears.
CH 16
CH 02
CH 03
Set the tag channels (scanned channel) before scanning.
Clear the tag channels which inconveniently stop scanning,
such as digital communication use.
Choose priority or normal scan in set mode. (p. 20)
NORMAL SCAN
CH 01 CH 02
CH 06
CH 05 CH 04
Normal scan, like priority scan, searches through all tag
channels in sequence. However, unlike priority scan, Ch 16
is not checked unless Ch 16 is set as a tag channel.

A WARNING STICKER is supplied with the transceiver.
To comply with FCC regulations, this sticker must be affixed in
such a location as to be readily seen from the operating controls of the radio. Make sure the chosen location is clean and
dry before applying the sticker.
■ Antenna
A key element in the performance of any communication system is an antenna. Ask your dealer about antennas and the
best places to mount them.
■ Fuse replacement
One fuse is installed in the supplied DC power cable. If a fuse
blows or the transceiver stops functioning, track down the
source of the problem, if possible, and replace the damaged
fuse with a new, rated one.
■ Cleaning
If the transceiver becomes dusty or dirty, wipe it clean with a
soft, dry cloth.
AVOID the use of solvents such as benzene or alcohol, as they may damage transceiver surfaces.

■ Installation
The optional HM-127 can be connected to the IC-M402 directly, as well as via the supplied connection cable for longer
distance remote operation. The connector of the connection
cable can be installed into a cabinet, wall, etc., as a built-in
plug.
For longer distance remote operation, the optional extension
cable, OPC-999 (6 m; 20 ft/Connecting between transceiver
and the connection cable.), is available, and up to 2 OPC-999
can be added.
q Insert the supplied cable into the external microphone jack
and tighten the cable nut as shown below.
w To use the supplied cable as a wall socket, follow the fol-
lowing steps.
e Using the mounting base, carefully mark off the 2 spots
where the cable and screws will be fastened.
r Drill holes at these marks.
t Install the mounting base using screws as shown below.
y The installation is finished
when it is completed.
