EXPLICIT DEFINITIONS
ii
If your vessel requires assistance, contact other vessels and
the Coast Guard by sending a distress call on Ch 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.

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 from a coast station.
• Channel 16 is automatically selected.
3. Push and hold [PTT], then transmit the appropriate
information as at left.
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.
