IN CASE OF EMERGENCY
If your vessel requires assistance, contact other vessels
and the Coast Guard by sending a distress call using DSC
(digital selective calling) on an emergency frequency.
When immediate help is needed:
1. Lift the key cover, hold down [DISTRESS] for 3
seconds until the 3 short beeps and then one
long beep sound.
2. Wait for an acknowledgment from another station.
3. After the acknowledgment is received, hold
down [PTT] on the microphone and send the
following information.
1“MAYDAY, MAYDAY, MAYDAY.”
2“THIS IS . . . . . . . . (name of the vessel).”
3“LOCATED AT . . . .(vessel’s position).”
4Give the reason for the distress call.
5Explain what assistance you need.
6Give additional information about your vessel:
• Type
• Length
• Color
• The number of people on board

RADIO OPERATION WARNING
WARNIN G
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

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.

THE MAXIMUM PERMISSIBLE EXPOSURE (MPE)
RADIUS HAS BEEN ESTIMATED TO BE A RADIUS
OF ABOUT 3M PER OET BULLETIN 65 OF THE

continuously for long periods.
BE CAREFUL! The remote controller’s front panel
meets IPX7 requirements for waterproof protection.
However, once the transceiver has been dropped,
or the waterproof seal is cracked or damaged,
waterproof protection cannot be guaranteed because
of possible damage to the case or the waterproof seal.
LThe connectors on the rear panel do not meet IPX7.

OPERATING RULES
NOTE: Before transmitting, monitor the channel you
want to use to avoid interrupting communications
already in progress.
zCALL PROCEDURE
Calls must be properly identied and the time limit
must be respected.
1. Give your call sign each time you call another ship
or Coast Guard station. If you have no call sign,
identify the station by giving your ship name and
the name of the licensee.
2. Give your call sign at the end of each transmission
that lasts more than 3 minutes.
3. You must break and give your call sign at least
once every 15 minutes during long ship-to-shore
calls.
4. Keep your unanswered calls short, less than 30
seconds. Do not repeat a call for 2 minutes.
5. Unnecessary transmissions are not allowed.
zPRIORITIES
1. Read all rules and regulations pertaining to
priorities and keep an up-to-date copy handy.
Safety and Distress calls take priority over any
other calls.
2. False or fraudulent Distress signals are prohibited
and punishable by law.
zPRIVACY
1. Information overheard, but not intended for you,
cannot lawfully be used in any case.
2. Indecent or profane language is prohibited.
zLOGS
1. All Distress, Emergency and Safety calls must
be recorded in complete details. Log data activity
is usually recorded for 24 hours. Universal Time
Coordinated (UTC) is frequently used.
2. Keep adjustments, repairs, channel frequency
changes and authorized modifications affecting
electrical operation of the equipment in the
maintenance log. The entries requires signatures
by the authorized licensed technician performing
or supervising the work.
zRADIO LICENSES
(1) SHIP RADIO STATION LICENSE
You need a current ship radio station license before
using the transceiver. It is unlawful to operate a ship
radio station which is not licensed, but required to be.
If required, contact 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 identication for radio
communication 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.
If required, the Restricted Radiotelephone Operator
Permit must be posted, or kept with the operator. If
required, 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.
A current copy of the applicable government rules and
regulations is only required to be on hand for vessels
in which a radio telephone is compulsory. However,
even if you are not required to have these on hand it
is your responsibility to be thoroughly acquainted with
all pertinent rules and regulations.

PREPARATION
■Entering the MMSI code
The Maritime Mobile Service Identity (MMSI: DSC self
ID) code consists of 9 digits. You can only enter the
code when turning ON the transceiver for the rst time.
This initial code can be entered only once.
After entering, it can be changed only by your dealer
or distributor.
If your MMSI code has already been entered, doing
the steps below is not necessary.
1. Hold down [ ] to turn ON the transceiver.
• Three short beeps sound, and then “Push [ENT] to
Register your MMSI” is displayed.
2. Push [ENT] to start entering the MMSI code.
• The “MMSI” screen is displayed.
LTo skip the entry, push [CLR] twice.
If you skip the entry, you cannot make a DSC call. To
enter the code after skipping, turn OFF the power, and
then turn it ON again.
3. Enter the MMSI code.
4. Repeat step 3 to enter all 9 digits.
5. Push the software key below to set the
entered code.
• The “MMSI CONFIRMATION” screen is displayed.
6. Enter your MMSI code again to confirm.
7. Push to set the confirmation code.
• When your MMSI code is successfully entered, “MMSI
Successfully Registered” is briey displayed, and then
the Main screen opens.
LYour MMSI code is also displayed on the opening screen.
