PRECAUTIONS

R short the terminals of the battery pack.
RUse and charge only specied 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, re, or cause the battery to

burst.

Rconnect the transceiver to an AC outlet. This may pose a

re hazard or result in an electric shock.

Rhold 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.

connect the transceiver to a power source other than the prod­ucts specied by Icom. Such a connection will ruin the trans­ceiver.

the exible 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.

The transceiver meets IPX8 requirements for waterproof pro­tection. However, once the transceiver has been dropped, wa­terproof protection cannot be guaranteed because of possible
damage to the transceiver's case or the waterproof seal.

OPERATING RULES

1

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

lawfully 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 govern­ment agency for a Ship-Radiotelephone license applica­tion. This government-issued license states the call sign

which is your craft’s identication 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 reg­ulations 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
regulations.

NOTE: Even though the transceiver is capable of op­eration 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 follow-

ing hazards: smoke, re, or battery rupture.

Misuse can also cause other battery damage or degrada­tion of battery performance.

• R DANGER! Use and charge only specied 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, re, 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 in-

side the battery may rupture or catch re.

• 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 res

or stoves, inside a sun-heated car, or by setting the bat­tery in direct sunlight may cause the battery to rupture

or catch re. 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 re.

• R DANGER! Use the battery only with the transceiver for
which it is specied. Never use a battery with any other
equipment, or for any purpose that is not specied in this

instruction manual.

• R DANGER! If uid 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.

• 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 uid from

inside the battery.

32

• R WARNING! NEVER put the battery in a microwave
oven, high-pressure container, or in an induction heating

cooker. This could cause overheating, a re, or cause the

battery to rupture.

• CAUTION: Always use the battery within the specied

temperature range for the transceiver*

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 specied temperature range

will reduce the battery’s performance and battery life.

Please note that the specied 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 ex-

cessive temperature environment (above +50˚C; +122˚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
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 res 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.

• R WARNING! DO NOT charge or leave the battery in the

battery charger beyond the specied time for charging.
If the battery is not completely charged by the specied

time, stop charging and remove the battery from the bat­tery charger. Continuing to charge the battery beyond

the specied time limit may cause a re, 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
terminals or damage the charger. The charger is not wa­terproof.

• CAUTION: DO NOT charge the battery outside of the
specied 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 specied temperature range. Additionally, battery

performance or battery life may be reduced.
