EXPLICIT DEFINITIONS
WORD DEFINITION
RWARNING! Personal injury, fire hazard or electric
shock may occur.
CAUTION Equipment damage may occur.
NOTE
If disregarded, inconvenience only. No risk
of personal injury, fire or electric shock.
CLEANTHETRANSCEIVER AND MICROPHONETHOR-
OUGHLY WITH FRESH WATER after exposure to water
including salt, otherwise, the keys and switch may become
inoperable due to salt crystallization.
Icom is not responsible for the destruction or damage to the
Icom transceiver, if the malfunction is because of:
• Force majeure, including, but not limited to, fires, earthquakes,
storms, floods, lightning, other natural disasters, disturbances,
riots, war, or radioactive contamination.
• The use of Icom transceivers with any equipment that is not
manufactured or approved by Icom.

IN CASE OF EMERGENCY
If your vessel requires assistance, contact other vessels and
the Coast Guard by sending a Distress call on Channel 16.
Or, transmit your Distress call using digital selective calling
on Channel 70.
INSTALLATION NOTE
Installation:
The installation of this equipment should be made in such a
manner as to respect the EC recommended electromagnetic
field exposure limits.(1999/519/EC)
The maximum RF power available from this device is 25
watts. The antenna should be installed as high as possible
for maximum efficiency and the installation height should be
at least 1.4 meters above any accessible position.In the case
where an antenna cannot be installed at a reasonable height,
then the transmitter should neither be continuously operated
for long periods if any person is within a distance of 1.4 me-
ters of the antenna, nor operated at all if any person is touch-
ing the antenna.
It is recommended that antenna of a maximum gain of 3 dB
are used. If higher gain antenna are required then please
contact your Icom distributor for revised installation recom-
mendations.
Operation:
The exposure to RF electromagnetic field is only applicable
when this device is transmitting. This exposure is naturally
reduced due to the nature of alternating periods of receiving
and transmitting. Keep your transmissions to the minimum
necessary.
USING CHANNEL 16
DISTRESS CALL PROCEDURE
1. “MAYDAY MAYDAY MAYDAY.”
2. “THIS IS ...............” (name of vessel).
3. Say your call sign or other description of the vessel (AND
9 digit DSC ID if you have one).
4. “LOCATED AT ...............” (your position).
5. State the nature of the distress and assistance required.
6. Give any other information which might facilitate the res-
cue.
USING DIGITAL SELECTIVE CALLING (Ch 70)
DISTRESS CALL PROCEDURE
1. While lifting up the key cover, hold down [DISTRESS]
for 3 seconds until you hear 3 short beeps and then one
long beep.
2. Wait for an acknowledgment on Channel 70 from a coast
station.
•After the acknowledgement is received, Channel 16 is auto-
matically selected.
3. Hold down [PTT], then transmit the appropriate informa-
tion as listed to the left.

PRECAUTIONS
RWARNING! NEVER connect the transceiver to an AC
outlet. This could cause a fire, electric shock and damage the
transceiver.
RWARNING! NEVER connect the transceiver to a pow-
er source of more than 16 V DC, such as a 24 V battery.This
could cause a fire and damage the transceiver.
RWARNING! NEVER reverse the DC power cable po-
larity when connecting to a power source.This could cause a
fire, electric shock and damage the transceiver.
RWARNING! NEVER remove the fuse holders on the
DC cable.This could cause a fire, electric shock and damage
the transceiver.
RWARNING! NEVER operate the transceiver during a
lightning storm. It may result in an electric shock, cause a
fire or damage the transceiver. Always disconnect the power
source and antenna before a storm.
CAUTION: NEVER place the transceiver where normal
operation of the vessel may be hindered or where it could
cause bodily injury.
KEEP the transceiver and microphone at least 1 m away
from the vessel’s magnetic navigation compass.
DO NOT place or leave the transceiver in areas with tem-
peratures below –20°C or above +60°C or, in areas subject to
intense 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.
DO NOT disassemble or modify the transceiver for any rea-
son.
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 meet IPX8 requirements
and the optional HM-195 commandmicIV™meet IPX7 re-
quirements for waterproof protection. However, once the
transceiver has been dropped, waterproof protection cannot
be guaranteed because of possible damage to the transceiv-
er’s case or the waterproof seal.

DPriorities
• Read all rules and regulations pertaining to call 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 calls are prohibited under law.
DPrivacy
• Information overheard, but not intended for you, cannot law-
fully be used in any way.
• Indecent or profane language is prohibited.
DRadio licenses
(1) SHIP STATION LICENSE
You may require a current radio station license before using
the transceiver.It is unlawful to operate a ship station which is
not licensed, but required to be.
If required, contact your dealer or the appropriate govern-
ment 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.
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 regu-
lations 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 regula-
tions.
