IN CASE OF EMERGENCY

WARNING.

WARNING
STICKER

NOTE

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 vessel (AND 9­digit 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.

Or, transmit your distress call using digital selective calling on
Channel 70.

USING DIGITAL SELECTIVE CALLING

DISTRESS CALL PROCEDURE

1. While lifting up the key cover, push and hold
[DISTRESS] for 5 sec. until you hear 5 short beeps
change to one long beep.

2. Wait for an acknowledgment from a coast station.

• Channel 16 is automatically selected.

3. Push and hold [PTT], then transmit the appropriate
information as listed above.

(Ch 70)

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 as in the diagram below. Make sure the cho­sen location is clean and dry before applying the sticker.

RADIO OPERATOR WARNING

WARNING

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.

PRECAUTION

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

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 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.
*IC-M402A only

OPERATING RULES

1

DD

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 must monitor Channel 16 when you are not operating
on another channel.

• False or fraudulent distress signals are prohibited and pun­ishable by law.

DD

PRIVACY

• Information overheard but not intended for you cannot law­fully be used in any way.

• Indecent or profane language is prohibited.

DD

RADIO 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 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.

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
regulation must still carry an FCC ship station license. For
further information, see the FCC Ship Radio Stations Fact
Sheet.

■ Description

Dualwatch monitors Channel 16 while you are receiving

channel while receiving another channel. Dualwatch/Tri-watch
are convenient for monitor Channel 16 when you are operat­ing on another channel.

DUALWATCH/TRI-WATCH SIMULATION

• If a signal is received on Channel 16, Dualwatch/Tri-watch
pauses on Channel 16 until the signal disappears.

SCAN OPERATION

■ Scan types

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 turned ON, the previously
selected (used) weather channel is also checked while scan­ning. (p. 31)

PRIORITY SCAN

Priority scan searches through all tag channels in sequence
while monitoring Channel 16. When a signal is detected on
Channel 16, scan pauses until the signal disappears; when
a signal is detected on a channel other than Channel 16,
scan becomes Dualwatch until the signal disappears.

Set the tag channels (scanned channel) before scanning.
Clear the tag channels which inconveniently stop scanning,
such as those for digital communication use.

Choose Priority or Normal scan in Set mode. (p. 31)

NORMAL SCAN

Normal scan, like Priority scan, searches through all tag
channels in sequence. However, unlike priority scan, Chan­nel 16 is not checked unless Channel 16 is set as a tag
channel.

SCAN OPERATION

Scan starts. When a signal is received.

channels or clear the tag for unwanted channels.
