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 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.
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 key cover, hold down [DISTRESS]
for 5 seconds until you hear 5 short beeps change to
one long beep.
2. Wait for an acknowledgment on Channel 70 from a
coast station.
•Aftertheacknowledgementisreceived,Channel16is
automatically selected.
3. Hold down [PTT], then transmit the appropriate
information as listed above.
NOTE
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.

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
expressly approved by Icom Inc., could void your authority to
operate this device under FCC regulations.
RWARNING! NEVER connect the transceiver to a
power source of more than 16 V DC or use reverse polarity.
This will ruin the transceiver.
RWARNING! NEVER cut the DC power cable between
the DC plug at the back of the transceiver and fuse holder. If
an incorrect connection is made after cutting, the transceiver
may be damaged.
CAUTION: NEVER place the transceiver where normal
operation of the vessel may be hindered or where it could
cause bodily injury.
CAUTION: 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 tem-
peratures below –4°F (–20°C) or above +140°F (+60°C), or
in areas subject to direct sunlight, such as the dashboard.
DO NOT use harsh solvents such as benzine or alcohol to
clean the transceiver, as they will damage the transceiver’s
surfaces. If the transceiver becomes dusty or dirty, wipe it
clean with a soft, dry cloth.
BE CAREFUL! The transceiver rear panel will become
hot when operating continuously for long periods of time.
Place the transceiver in a secure place to avoid inadvertent
use by children
BE CAREFUL! The transceiver employs waterproof
construction, which corresponds to IPX7 of the international
standard IEC 60529 (2001). However, once the transceiver
has been dropped, waterproofing cannot be guaranteed due
to the fact that the case may be cracked, or the waterproof
seal damaged, etc.
Approved Icom optional equipment is designed for optimal
performance when used with an Icom transceiver.
Icom is not responsible for the destruction or damage to an
Icom transceiver in the event the Icom transceiver is used
with equipment that is not manufactured or approved by
Icom.

OPERATING RULES
D PRIORITIES
•Readallrulesandregulationspertainingtoprioritiesand
keep an up-to-date copy handy. Safety and Distress calls
take priority over all others.
•YoumustmonitorChannel16whenyouarenotoperating
on another channel.
•Falseorfraudulentdistresssignalsareprohibitedandpun-
ishable by law.
D PRIVACY
•Informationoverheardbutnotintendedforyoucannotlaw-
fully be used in any way.
•Indecentorprofanelanguageisprohibited.
D 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 op-
erator may operate a transceiver.
However, non-licensed individuals may talk over a trans-
ceiver 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.

n 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 previ-
ously selected (last used) weather channel is also checked
while scanning. (p. 33)
Set the TAG channels (scanned channel) before scanning.
Clear the TAG channels which inconveniently stop scanning,
such as those for digital communication use. (Refer to right
page for details.)
Choose Priority or Normal scan in the Set mode. (p. 42)

Priority scan searches through all TAG channels in se-

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 sig-
nal disappears.

fuse blows or the transceiver stops functioning, track down
the source of the problem, if possible, and replace the dam-
aged fuse with a new one of the proper rating.
Fuse rating: 10 A
n Cleaning
If the transceiver becomes dusty or dirty, wipe it clean with a
soft, dry cloth.
