SAFETY TRAINING INFORMATION

Your Icom radio generates RF electromagnetic energy during
transmit mode.

This radio has been evaluated for compliance at the distance
of 2.5 cm with the FCC RF exposure limits for “Occupational
Use Only”. In addition, your Icom radio complies with the fol­lowing Standards and Guidelines with regard to RF energy
and electromagnetic energy levels and evaluation of such lev-

els for exposure to humans:

• FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance
with FCC Guidelines for Human Exposure to Radio Frequency Electro­magnetic Fields.

• American National Standards Institute (C95.1-1992), IEEE Standard for
Safety Levels with Respect to Human Exposure to Radio Frequency Elec­tromagnetic Fields, 3 kHz to 300 GHz.

• American National Standards Institute (C95.3-1992), IEEE Recommended
Practice for the Measurement of Potentially Hazardous Electromagnetic
Fields– RF and Microwave.

• The following accessories are authorized for use with this product. Use of
accessories other than those specified may result in RF exposure levels
exceeding the FCC requirements for wireless RF exposure.; Belt Clip
(MB-86, MB-103Y), Rechargeable Ni-Cd Battery Pack (BP-224) and
Lithium Battery Pack (BP-234).

To ensure that your expose to RF electromagnetic en­ergy is within the FCC allowable limits for occupational
use, always adhere to the following guidelines:

CAUTION

WARNING

• DO NOT operate the radio without a proper antenna attached, as this may
damage the radio and may exceed FCC RF exposure limits. Aproper an­tenna is the antenna supplied with this radio by the manufacturer or an an­tenna specifically authorized by the manufacturer for use with this radio.

• DO NOT transmit for more than 50% of total radio use time (“50% duty
cycle”). Transmitting more than 50% of the time can cause FCC RF expo­sure compliance requirements to be exceeded. The radio is transmitting
when the “TX indicator” light is red. Y ou can cause the radio to transmit by
pressing the “PTT” switch or VOX function.

• ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body
when transmitting and only use the Icom belt-clips which are listed on
page 26 when attaching the radio to your belt, etc., to ensure FCC RF ex­posure compliance requirements are not exceeded.To provide the recipi­ents of your transmission the best sound quality, hold the radio in an
almost vertical position at least 5 cm (2 inches) from your mouth, the mi­crophone is located next to the speaker, so you should “talk into the
speaker”.

The information listed above provides the user with the information needed to
make him or her aware of RF exposure, and what to do to assure that this radio
operates within FCC RF exposure limits.

Electromagnetic Interference/Compatibility

During transmissions, your Icom radio generates RF energy that can possibly
cause interference with other devices or systems. To avoid such interference,
turn off the radio in areas where signs are posted to do so. DO NOT operate
the transmitter in areas that are sensitive to electromagnetic radiation such as
hospitals, aircraft, and blasting sites.

PRECAUTION

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-224 or BP-234. 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) for U.S.A. version;.–20°C (–4°F) or above
+55°C (+131°F) for General version

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

OPERATING RULES

1

D Priorities

• Read all rules and regulations pertaining to 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

When your craft is equipped with a VHF FM transceiver, 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 government
agency for a Ship-Radiotelephone license. This license in­cludes 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.

The Restricted Radiotelephone Operator Permit must be
posted near the transceiver or be kept with the operator. 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.

• NEVER dispose of the BP-234 battery pack in a fire. This could re­sult in an explosion.

• DO NOT short-circuit the BP-234 battery pack. Metal contact (such
as paper clip, another battery, etc.) across the battery contacts can
result in a sustained high rate discharge, which could damage the
battery, void the warranty and create a burn or a fire hazard.

• NEVER expose of the BP-234 battery pack to excessive heat of
60°C (+140°F) or above. This could result in electrolyte leakage,
possibly causing an explosion or fire.

• NEVER attempt to recharge the BP-234. Lithium batteries may ex-
plode or cause a fire in such cases.

• DO NOT disassemble the BP-234 battery pack. The BP-234 bat-
tery pack contains no user serviceable parts. Internal battery gas
can cause throat irritation. Also, exposed lithium may generate heat
and ignite.

• DO NOT apply excessive pressure to the battery. This may result
in electrolyte leakage, possibly causing an explosion.

• The storage life of the BP-234 is about 5 years. Once the expira­tion date on the battery pack passes, a new battery pack must be
purchased.

• For safety reasons, once the BP-234 is used, a spare one should be
purchased. The original battery pack can be continued to be used
for regular communications; save the spare one for emergency sit­uations.

• BP-234 Lithium battery pack

IMPORTANT!

• This battery pack is for EMERGENCY USE ONLY.

• Store at temperatures below +35°C (+95°F).

• Once this bag’s seal is broken, a new emergency battery

pack must be used for EMERGENCY use.

■ Battery charging

Prior to using the transceiver for the first time, the battery
pack must be fully charged for optimum life and operation.

CAUTION: To avoid damage to the transceiver, turn the
power OFF while charging.

• Recommended temperature range for charging:
+10°C to +40°C (+50°F to +104°F)

• Use the specified chargers (BC-158, BC-119N and
BC-121N). NEVER use another manufacture’s charger.

• Use the supplied AC adapter for the BC-158. NEVER use
another manufacture’s adapters.

D Recycling information

The product that you have purchased contains a
rechargeable battery. The battery is recyclable.
At the end of its life, under various state and
local laws, it may be illegal to dispose of this bat­tery into the municipal waste stream. Call 1-800­822-8837 for battery recycling options in your
area or contact your dealer.

■ Battery cautions

CAUTION! NEVER insert a battery pack or a trans-

ceiver (with the battery pack attached) that is wet or soiled
into the charger. This may result in corrosion of the charger
terminals or damage to the charger. The charger is not wa­terproof and water can easily get into it.

NEVER incinerate used battery packs. Internal battery gas

may cause an explosion.

NEVER immerse a battery pack in water. If the battery

pack becomes wet, be sure to wipe it dry immediately (par­ticularly the battery terminals), and especially BEFORE at­taching it to the transceiver.

NEVER short terminals of the battery pack. Also, current

may flow into nearby metal objects, such as a necklace, etc.
Those may cause burn, electric shock or fire. Therefore, be
careful when carrying in a pocket, backpack or handbag, and
when placing the radio near metal objects.

If your battery pack seems to have no capacity even after
being charged, completely discharge it by leaving the power
ON overnight. Then, fully charge the battery pack again. If the
battery still do not retain a charge (or very little), a new battery
pack must be replaced.

Turn the transceiver OFF when charging an attached bat­tery pack. Otherwise, the battery pack may not become full­charging or may not charge properly.
