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.
CLEAN THE TRANSCEIVER AND MICROPHONE THOR-
OUGHLY WITH FRESH WATER after exposure to water
including salt, otherwise, the keys and switch may become
inoperable due to salt crystallization.

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.

PRECAUTIONS
RWARNING! NEVER connect the transceiver to an AC
outlet. This may pose a fire hazard or result in an electric shock.
RWARNING! NEVER connect the transceiver to a pow-
er 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.
KEEP the transceiver and microphone at least 1 m away
from the vessel’s magnetic navigation compass.
DO NOT use or place the transceiver in areas with tem-
peratures below –20°C or above +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.
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 c o m m a n d m i c IV™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.

Radio licensesD
(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.
