RDANGER! NEVER short the terminals of the battery

pack.

RDANGER! Use and charge only speciﬁed Icom battery

packs with Icom radios or Icom chargers. Only Icom battery packs

are tested and approved for use with Icom radios or charged with

Icom chargers. Using third-party or counterfeit battery packs or

chargers may cause smoke, ﬁre, or cause the battery to burst.

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 an-

tenna is closer than 2.5 cm (1 inch) from exposed parts of the

body, especially the face or eyes, while transmitting. The trans-

ceiver will perform best if the microphone is 5 to 10 cm (2 to 4

inches) away from the lips and the transceiver is vertical.

CAUTION: NEVER connect the transceiver to a power

source other than the products speciﬁed by Icom. Such a connec-

tion will ruin the transceiver.

CAUTION: MAKE SURE the ﬂexible antenna and bat-

tery 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 transceiver meets IPX8 requirements

for waterproof protection. However, once the transceiver has

been dropped, waterproof protection cannot be guaranteed be-

cause of possible damage to the transceiver's case or the water-

proof seal.

DO NOT use or place the transceiver in direct sunlight or in

areas with temperatures below –20°C (–4°F) or above +60°C

(+140°F) for the EXP/USA versions, below –15°C (+5°F) or

above +55°C (+131°F) for the CHN/EUR/FRG/HOL/UK versions,

and below –10°C (+14°F) or above +55°C (+131°F) for the AUS

versions.

DO NOT use harsh solvents such as benzine or alcohol when

cleaning, as they will damage the transceiver surfaces.

DO NOT push [PTT] when not actually intending to transmit.

DO NOT modify the transceiver. The transceiver warranty does

not cover any problems caused by unauthorized modiﬁcation.

DO NOT operate the transceiver near unshielded electrical

blasting caps or in an explosive atmosphere.

KEEP the transceiver out of the reach of children.

KEEP the transceiver at least 0.9 meter (3.0 feet) away from

your vessel’s magnetic navigation compass.

RADIO OPERATOR WARNING

WARNING

Icom requires the radio operator to meet the

FCC and IC Requirements for Radio Frequency

Exposure. 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 and IC Safe Maximum Permissible Exposure (MPE) dis-

tance 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 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 allow-

able MPE level set by FCC and IC.

FAILURE TO OBSERVE THESE LIMITS MAY ALLOW

THOSE WITHIN THE MPE RADIUS TO EXPERIENCE RF

RADIATION ABSORPTION WHICH EXCEEDS THE MAXI-

MUM 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) RADIUS

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.

AVERTISSEMENT POUR LES OPÉRATEURS RADIO

Icom exige que l'opérateur radio se conforme

aux exigences de la FCC et d’IC 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) verticalement 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 mat-

ière 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 et d’IC, 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 et d’IC.

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.

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.

OPERATING RULES

New2001

D Priorities

• 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.

D Privacy

• Information overheard, but not intended for you, cannot law-

fully be used in any way.

• Indecent or profane language is prohibited.

D Radio 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.

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.

■ 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 degrada-

tion 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 bat-

tery. 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 tempera-

ture 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 per-

formance 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 NEV-

ER modify the battery pack. This may cause heat genera-

tion, 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 wa-

ter, without rubbing them, and see a doctor immediately.

• R 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.

• R WARNING! Immediately wash, using clean water, any

part of the body that comes into contact with ﬂuid from in-

side the battery.

BATTERY CHARGING

New2001

• R 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 tem-

perature range for the transceiver*

and the battery itself

(–20˚C to +60˚C; –4˚F to +140˚F).

* EXP/USA : –20˚C to +60˚C; –4˚F to +140˚F

CHN/EUR/FRG/HOL/UK : –15˚C to +55˚C; +5˚F to +131˚F

AUS : –10˚C to +55˚C; +14˚F to +131˚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 transceiv-

er 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 +50˚C; +122˚F) for an ex-

tended period of time. If the battery must be left unused for a

long time, it must be detached from the radio after discharg-

ing. You may use the battery until the remaining 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)

–20˚C to +35˚C (–4˚F to +95˚F) (within three months)

–20˚C to +20˚C (–4˚F to +68˚F) (within a year)

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 en-

vironments, the safety/protection circuit in the battery will

activate, causing the battery to stop charging.

• R 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 char-

ger. Continuing to charge the battery beyond the speciﬁed

time limit may cause a ﬁre, overheating, or the battery may

rupture.

• R 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 termi-

nals or damage the charger. The charger is not waterproof.

• CAUTION: DO NOT charge the battery outside of the speci-

ﬁed temperature range: +10˚C to +40˚C (+50˚F to +104˚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 perfor-

mance or battery life may be reduced.

De ruis is niet te onderdrukken, wat kan je hier aan doen? Gesteld op 26-1-2025 om 08:36
Reageer op deze vraag Misbruik melden
Mijn 1ste vraag gaat over wat de juiste manier is wat betreft de squelch instelling. Dit betreft de IC-M73EURO.
Staat de instelling “1” net iets boven de ruis of moet het dan juist instelling “10” zijn ?
Tijdens mijn loopbaan bij de koopvaardij werkte ik veelvuldig met een portofoon en daar draaide je de squels tot aan het ruis en dan ietsjes terug. Dan was de instelling juist.
Mijn 2de vraag betreft het duplex kanaal. Ook al wil ik een ander vaartuig op VHF kanaal 3 oproepen, mijn uitgezonden signaal gaat eerst naar het verkeer/wal station welke dan op een andere frequentie naar het opgeroepen vaartuig gaat. Moet ik dan tijdens het gesprek de PTT ingedrukt houden ? Of gaat dit net zo als op de andere kanalen? Zenden-luisteren-zenden.
Graag uitleg hierover. Gesteld op 23-5-2023 om 12:58
