EXPLICIT DEFINITIONS
WORD DEFINITION
R WARNING! Personal injury, fire hazard or
electric shock may occur.
CAUTION Equipment damage may occur.
NOTE
If disregarded, inconvenience only.
No risk or personal injury, fire or
electric shock.
RWARNING HIGH VOLTAGE! NEVER at-
tach an antenna to antenna connectors during trans-
mission. This may result in an electrical shock or burn.
RWARNING! NEVER connect the transceiver
to an AC outlet directly. This may pose a fire hazard or
result in an electric shock.
RWARNING! NEVER mount the transceiver
main unit overhead. The weight of the unit is approxi-
mately 4.7 kg (10 lb 6 oz), but its apparent weight will
increase several fold due to wave shocks or vibration.
The unit must be mounted on a flat hard surface only.
RWARNING! NEVER place the transceiver
where normal operation of the ship or vehicle may be
hindered or where it could cause bodily injury.
RWARNING! NEVER let metal, wire or other ob-
jects touch any internal part or connectors on the rear
panel of the transceiver. This may result in an electric
shock.
CAUTION: NEVER expose the transceiver to rain,
snow or any liquids.
CAUTION: NEVER connect a power source of
more than 15.64 V DC, such as a 24 V battery. This
connection could cause a fire or ruin the transceiver.
DO NOT place the transceiver in excessively dusty en-
vironments or in direct sunlight.
DO NOT place the transceiver against walls or putting
anything on top of the transceiver. This will obstruct
heat dissipation.
DO NOT use or place the transceiver in areas with
temperatures below –20°C (–4°F) or above +55°C
(+131°F).
DO NOT use harsh solvents such as benzine or al-
cohol 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 heatsink will become hot when op-
erating the transceiver continuously for long periods.
During maritime mobile operation, KEEP the trans-
ceiver and microphone as far away as possible (at
least 1 m; 3 ft) from the magnetic navigation compass
to prevent erroneous indications.
Use Icom microphones only (supplied). Other manu-
facturer’s microphones have different pin assignments,
and connection to the IC-M802 may damage the trans-
ceiver.
Place the unit in a secure place to avoid inadvertent
use by children.

short beeps become one long beep, to send the
distress call.
wAfter the appropriate traffic frequency is automati-
cally selected (after an acknowledgement call is
received), hold down the PTT switch on the micro-
phone and send the following information.
1. “MAY DAY, MAY DAY, MAY DAY.”
2. “THIS IS . . . . . . . . ” (name of ship)
3. “LOCATED AT . . . ” (ship’s position)
4. Give the reason for the distress call.
5. Explain what assistance you need.
6. Give additional information:
 •Shiptype
 •Shiplength
 •Shipcolor
 •Numberofpeopleon-board
When potential problems exist
qPush [DSC] to select DSC watch mode, if neces-
sary.
wPush [MODE set] to select DSC menu, rotate
[CH] to select “All ships” then push [ENT].
eFollow the guidance displayed on the LCD (bottom
line), to set up the category, traffic frequency and
calling frequency with [CH], [ENT] and keypad.
rHold down [CANCEL/CALL] for 1 second until the
short beeps become one long beep.

OPERATING RULES AND GUIDELINES
2001 NEW

Quick Reference
Before transmitting, monitor the channel you wish to
use to avoid interrupting transmissions already in
progress.
• CALL PROCEDURE
Calls must be properly identified and the time limit
must be respected.
qGive 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.
wGive your call sign at the end of each transmission
that lasts more than 3 minutes.
eYou must break and give your call sign at least once
every 15 minutes during long ship-to-shore calls.
rKeep your unanswered calls short, less than 30 sec-
onds. Do not repeat a call for 2 minutes.
tUnnecessary transmissions are not allowed.
• PRIORITIES
qRead all rules and regulations pertaining to priori-
ties and keep an up-to-date copy handy. Safety and
distress calls take priority over all others.
wFalse or fraudulent distress signals are prohibited
and punishable by law.
• PRIVACY
qInformation overheard but not intended for you, can-
not lawfully be used in any way.
wIndecent or profane language is prohibited.
• LOGS
qAll distress, emergency and safety calls must be
recorded in complete details. Log data activity is
usually recorded in 24 hour time. Universal Time
Coordinated (UTC) is frequently used.
wAdjustments, repairs, channel frequency changes
and authorized modifications affecting electrical op-
eration of the equipment must be kept in the main-
tenance log; entries must be signed by the autho-
rized licensed technician performing or supervising
the work.
• 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 govern-
ment agency for a Ship-Radiotelephone license appli-
cation. This government-issued license states the call
sign which is your craft’s identification for radio pur-
poses.
(2) OPERATOR’S LICENSE
A Restricted Radiotelephone Operator Permit is the
license most often held by small ship 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 operator may operate the transceiver.
However, non-licensed individuals may talk over a
transceiver if a licensed operator starts, supervises,
and ends the call and makes the necessary log en-
tries.
Keep a copy of the current government rules and regu-
lation handy.

strong signals and to obtain a constant output level.
When receiving weak signals with adjacent strong
signals or noise, the AGC function may reduce the

D RF gain setting
The receiver gain can be reduced with the RF gain
setting. This may help to remove undesired weak sig-
nals while monitoring strong signals.
Usually, the AGC function reduces the RF gain ac-
cording to the receive signal strength, and these
weak signals are removed. However, when no signal
is received, these weak signals may not be heard.
In such cases, the RF gain may be useful to set a
minimum level at which to hear signals.
