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.
FEATURES
☞ Submersible construction
Built tough to withstand the punishing marine
environment, the IC-M73/IC-M73EURO’s submersible
constr uction meets IPX8 of the corresponding
International Standard IEC 60529 (2001) while using BP-
245N.
In addition, the new speaker grill structure with a water
self-draining function is helpful for draining water or
seawater easily.
☞ Dualwatch and tri-watch functions
Convenient functions that allow you to monitor the
distress channel (Ch 16) while receiving one other
channel of your choice (dualwatch), or while receiving one
other channel of your choice and the call channel (Ch 09)
(tri-watch). See p. 16 for details.
☞ Large, easy-to-read LCD
With the generous dimensions of 22.5(H) × 31.5(W) mm;
7⁄8(H) × 11⁄4(W) inch, the IC-M73/IC-M73EURO’s function
display is easy to read and shows operating conditions
at a glance. Backlighting and contrast can be adjusted to
suit your preferences.
☞ Simple operation
The volume knob is on top of the radio, while the channel
buttons are on the front panel. This allows for convenient,
one-handed operation.
ii
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.
RWARNING! NEVER connect the transceiver to an
AC outlet. This may pose a fire hazard or result in an electric
shock.
RWARNING! NEVER hold the transceiver so that
the antenna is closer than 2.5 cm (1 inch) from exposed parts
of the body, especially the face or eyes, while transmitting.
The transceiver will perform best if the microphone is 5 to
10 cm (2 to 4 inches) away from the lips and the transceiver is
vertical.
NEVER connect the transceiver to a power source
other than the BP-245N. Such a connection will ruin the
transceiver.
AVOID using or placing the transceiver in direct sunlight
or in areas with temperatures below –20°C (–4°F) or above
+60°C (+140°F).
KEEP the transceiver out of the reach of children.
KEEP the transceiver at least 0.9 meters (3.0 ft) away from
your vessel’s magnetic navigation compass.
MAKE SURE the flexible antenna and battery pack are
securely attached to the transceiver, and that the antenna
and battery pack are dry before attachment. Exposing
the inside of the transceiver to water will result in serious
damage to the transceiver.
BE CAREFUL! The IC-M73/IC-M73EURO employs
submersible construction (1.5 m; 4.9 ft depth for 30 min.).
However, once the transceiver has been dropped,
waterproofing cannot be guaranteed due to the fact that
the transceiver may be cracked, or the waterproof seal
damaged, etc.
For the U.S.A. only

PRECAUTION
iii
RADIO OPERATOR WARNING
WARNING
Icom requires the radio operator to meet the
FCC Requirements for Radio Frequency Expo-
sure. An omnidirectional antenna with gain not
greater than 9 dBi must be mounted a mini-
mum 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 com-
pliance 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 verti-
cally 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 al-
lowable 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 EXPO-
SURE 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) RA-
DIUS 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 MAXI-
MUM GAIN OF 9dBi ARE USED FOR A SHIP MOUNTED
SYSTEM.
iv
AVERTISSEMENT POUR LES OPÉRATEURS RADIO
Icom exige que l'opérateur radio se conforme aux
exigences de la FCC en matière d'exposition aux
radiofréquences. Une antenne omnidirectionnelle
dont le gain ne dépasse pas 9dBi doit être fixée
à une distance minimale de 5 mètres (mesurée
depuis le point le plus bas de l'antenne) verticale-
ment au-dessus du pont principal et de tout le personnel qui peut
s'y trouver. Il s'agit de la distance de sécurité minimale prévue pour
satisfaire aux exigences de conformité en matière d'exposition aux
RF. Cette distance de 5 mètres est établie en fonction de l'exposition
maximale admissible sécuritaire de 3 mètres établie par la FCC, à
laquelle on ajoute la hauteur d'un adulte (2 mètres); cette distance
convient pour tous les navires.
Dans le cas des embarcations sans structure convenable, l'antenne
doit être fixée de façon à maintenir une distance minimale de 1 mètre
verticalement entre cette antenne (mesurée depuis son point le plus
bas) et la tête de toute personne présente; toutes les personnes
présentes doivent se tenir à l'extérieur d'un rayon d'exposition maxi-
male admissible de 3 mètres.
Ne pas émettre à l'aide de la radio et de l'antenne lorsque des
personnes se trouvent à l'intérieur du rayon d'exposition maximale
admissible de cette antenne, à moins que ces personnes (comme
le conducteur ou l'opérateur radio) ne soient protégées du champ
de l'antenne par un écran métallique relié à la masse. Le rayon
d'exposition maximale admissible équivaut à la distance minimale
que cette personne doit maintenir entre elle et l'axe de l'antenne pour
éviter une exposition aux RF supérieure au niveau d'exposition maxi-
male admissible fixé par la FCC.
LE NON-RESPECT DE CES LIMITES PEUT CAUSER, POUR LES
PERSONNES SITUÉES DANS LE RAYON D'EXPOSITION MAXI-
MALE ADMISSIBLE, UNE ABSORPTION DE RAYONNEMENT DE
RF SUPÉRIEURE À L'EXPOSITION MAXIMALE ADMISSIBLE
FIXÉE PAR LA FCC.
L'OPÉRATEUR RADIO EST RESPONSABLE D'ASSURER QUE
LES LIMITES D'EXPOSITION MAXIMALE ADMISSIBLE SOIENT
RESPECTÉES EN TOUT TEMPS PENDANT LA TRANSMISSION
RADIO. L'OPÉRATEUR RADIO DOIT S'ASSURER QU'AUCUNE
PERSONNE PRÉSENTE NE SE SITUE À L'INTÉRIEUR DU RAY-
ON D'EXPOSITION MAXIMALE ADMISSIBLE.
Établir le rayon d'exposition maximale admissible
ON ESTIME QUE LE RAYON D'EXPOSITION MAXIMALE ADMIS-
SIBLE EST D'ENVIRON 3 M, TEL QUE STIPULÉ DANS LE BUL-
LETIN OET 65 DE LA FCC. CETTE DISTANCE ESTIMÉE TIENT
COMPTE D'UN SYSTÈME INSTALLÉ SUR UN NAVIRE UTILISANT
LA PUISSANCE MAXIMALE DE LA RADIO ET DES ANTENNES
DONT LE GAIN MAXIMAL EST DE 9dBi.

fully be used in any way.
Radio licenses D
(1)SHIPSTATIONLICENSE
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.
NOTE: Even though the transceiver is capable of opera-
tion on VHF marine channels 3, 21, 23, 61, 64, 81, 82 and
83, according to FCC regulations these simplex channels
cannot be lawfully used by the general population in USA
waters.

■ Scan types
Scanning is an efficient way to quickly locate signals over a
wide frequency range. The transceiver has a priority scan
setting and normal scan setting.
In addition, the “Weather alert” and “Auto scan” functions are
also available for scanning. These functions can be activated
simultaneously, depending on the settings on the SET mode.
(pp. 18, 19)
Set the Favorite channels (scanned channel) before scanning.
Clear those Favorite channels which are not needed or in-
conveniently stop scanning, such as digital communications.
Choose priority or normal scan on the SET mode. (p. 18)

■ Battery cautions
Misuse of Lithium-ion batteries may result in the
following hazards: smoke, fire, or battery rupture.
Misuse can also cause other battery damage or
degradation of battery performance.
R DANGER! Use and charge only specified Icom battery
pack with Icom transceiver. Only Icom battery pack is
tested and approved for use with Icom transceiver. Using
third-party or counterfeit battery packs may cause smoke,
fire, or cause the battery to burst.
D Battery caution
R DANGER! DO NOT hammer or otherwise impact the
battery. Do not use the battery if it has been severely
impacted or dropped, or if the battery has been subjected
to heavy pressure. Battery damage may not be visible on
the outside of the case. Even if the surface of the battery
does not show cracks or any other damage, the cells inside
the battery may rupture or catch fire.
R DANGER! NEVER use or leave battery pack in
areas with temperatures above +60˚C (+140˚F). High
temperature buildup in the battery, such as could occur
near fires or stoves, inside a sun-heated car, or by setting
the battery in direct sunlight may cause the battery to
rupture or catch fire. Excessive temperatures may also
degrade battery performance or shorten battery life.
R DANGER! DO NOT expose the battery to rain, snow,
seawater, or any other liquids. Do not charge or use a wet
battery. If the battery gets wet, be sure to wipe it dry before
using. The battery by itself is not waterproof.
R DANGER! NEVER incinerate a used battery pack since
internal battery gas may cause a rupture or explosion.
R DANGER! NEVER solder the battery terminals, or
NEVER modify the battery pack. This may cause heat
generation, and the battery may rupture, emit smoke or
catch fire.
R DANGER! Use the battery only with the transceiver for
which it is specified. Never use a battery with any other
equipment, or for any purpose that is not specified in this
instruction manual.
R DANGER! If fluid from inside the battery gets in your
eyes, blindness can result. Rinse your eyes with clean
water, without rubbing them, and see a doctor immediately.
WARNING! Immediately stop using the battery if it emits
an abnormal odor, heats up, or is discolored or deformed. If
any of these conditions occur, contact your Icom dealer or
distributor.
WARNING! Immediately wash, using clean water, any part
of the body that comes into contact with fluid from inside
the battery.
32
9Battery charging
WARNING! NEVER put the battery in a microwave oven,
high-pressure container, or in an induction heating cooker.
This could cause overheating, a fire, or cause the battery
to rupture.
CAUTION! Always use the battery within the specified
temperature range for the transceiver (–20˚C to +60˚C;
–4˚F to +140˚F) and the battery itself (–20˚C to +60˚C;
–4˚F to +140˚F). Using the battery out of its specified
temperature range will reduce the battery’s performance
and battery life. Please note that the specified temperature
range of the battery may exceed that of the transceiver. In
such cases, the transceiver may not work properly because
it is out of its operating temperature range.
CAUTION! Shorter battery life could occur if the battery
is left fully charged, completely discharged, or in an
excessive temperature environment (above +45˚C; +113˚F)
for an extended period of time. If the battery must be left
unused for a long time, it must be detached from the radio
after discharging. You may use the battery until the remain-You may use the battery until the remain-
ing capacity is about half, then keep it safely in a cool dry
place with the temperature range as below;
–20˚C to +50˚C (–4˚F to +122˚F) (within a month)

D Charging caution
R DANGER! NEVER charge the battery pack in areas with
extremely high temperatures, such as near fires or stoves,
inside a sun-heated car, or in direct sunlight. In such
environments, the safety/protection circuit in the battery will
activate, causing the battery to stop charging.
WARNING! DO NOT charge or leave the battery in the
battery charger beyond the specified time for charging. If
the battery is not completely charged by the specified time,
stop charging and remove the battery from the battery
charger. Continuing to charge the battery beyond the
specified time limit may cause a fire, overheating, or the
battery may rupture.
WARNING! NEVER insert the battery and transceiver
(battery attached to the transceiver) into the charger if it
is wet or soiled. This could corrode the battery charger
terminals or damage the charger. The charger is not
waterproof.
CAUTION! DO NOT charge the battery outside of the
specified temperature range: ±0˚C to +45˚C (+32˚F to
+113˚F). Icom recommends charging the battery at +20˚C
(+68˚F). The battery may heat up or rupture if charged out
of the specified temperature range. Additionally, battery
performance or battery life may be reduced.
