SAFETY TRAINING INFORMATION

Your Icom radio generates RF electromagnetic energy during

transmit mode. This radio is designed for and classified as

“Occupational Use Only”, meaning it must be used only during

the course of employment by individuals aware of the haz-

ards, and the ways to minimize such hazards. This radio is

NOT intended for use by the “General Population” in an un-

controlled environment.

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 levels for ex-

posure to humans:

• FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance

with FCC Guidelines for Human Exposure to Radio Frequency Electro-

magnetic Fields.

• American National Standards Institute (C95.1-1992), IEEE Standard for

Safety Levels with Respect to Human Exposure to Radio Frequency Elec-

tromagnetic 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-

109), Rechargeable Li-Ion Battery Pack (BP-252) and Alkaline Battery

Case (BP-251).

To ensure that your expose to RF electromagnetic en-

ergy 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

damaged the radio and may also cause you to exceed FCC RF exposure

limits. A proper antenna is the antenna supplied with this radio by the man-

ufacturer or 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 expo-

sure compliance requirements to be exceeded. The radio is transmitting

when the “TX indicator” lights red. You can cause the radio to transmit by

pressing the “PTT” switch.

•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 29 when attaching the radio to your belt, etc., to ensure FCC RF ex-

posure compliance requirements are not exceeded. To provide the recipi-

ents of your transmission the best sound quality, hold the antenna at least

5 cm (2 inches) from your mouth, and slightly off to one side.

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 with the FCC RF exposure limits of this radio.

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.

Occupational/Controlled Use

The radio transmitter is used in situations in which persons are exposed as

consequence of their employment provided those persons are fully aware of

the potential for exposure and can exercise control over their exposure.

IN CASE OF EMERGENCY

If your vessel requires assistance, contact other vessels and

the Coast Guard by sending a distress call on Channel 16.

❍USING CHANNEL 16

DISTRESS CALL PROCEDURE

1. “MAYDAY MAYDAY MAYDAY.”

2. “THIS IS ...........................” (name of vessel)

3. Your call sign or other indication of the ves-

sel.

4. “LOCATED AT .....................” (your position)

5. The nature of the distress and assistance re-

quired.

6. Any other information which might facilitate

the rescue.

RECOMMENDATION

CLEAN THE TRANSCEIVER THOROUGHLY WITH FRESH

WATER after exposure to saltwater, and dry it before opera-

tion. Otherwise, the transceiver's keys, switches and con-

trollers may become inoperable due to salt crystallization.

NOTE: DO NOT wash the transceiver in water if there is any

reason to suspect the waterprooﬁng may not be effective. For

example, in cases where the battery pack rubber seal is dam-

aged, the transceiver/battery pack is cracked or broken, or

has been dropped, or when the battery pack is detached from

the transceiver.

PRECAUTIONS

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 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.

NEVER connect the transceiver to a power source other

than the BP-251 (option) or BP-252. 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.

BE CAREFUL! The transceiver’s right-side panel will

become hot when operating continuously for long periods.

BE CAREFUL! The transceiver employs waterproof

construction, which corresponds to IPX7 of the international

standard IEC 60529 (2001). However, once the transceiver

has been dropped, waterprooﬁng cannot be guaranteed due

to the fact that the transceiver may be cracked, or the water-

proof seal damaged, etc.

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.

OPERATING RULES

DPriorities

• 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.

DPrivacy

• Information overheard but not intended for you cannot law-

fully be used in any way.

• Indecent or profane language is prohibited.

DRadio 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 in-

cludes 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 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 regulations.

NOTE: Even though the IC-M34 is capable of operation

on VHF marine channels 3, 21, 23, 61, 64, 81, 82 and 83,

■Scan types

Scanning is an efﬁcient way to locate signals quickly over a

wide frequency range. The transceiver has priority scan and

normal scan.

In addition, the weather alert and auto scan function is avail-

able for standby convenience. These functions can be acti-

vated simultaneously, depending on the settings in set mode.

(pgs. 18, 19)

Set the TAG channels (scanned channel) before scanning.

Clear the TAG channels which inconveniently stop scanning,

such as digital communications.

Choose priority or normal scan in set mode. (p. 18)

PRIORITY SCAN

Priority scan searches through all TAG channels in se-

quence while monitoring Channel 16. When a signal is de-

tected on Channel 16, scan pauses until the signal disap-

pears; when a signal is detected on a channel other than

Channel 16, scan becomes dualwatch until the signal dis-

appears.

BATTERY CHARGING

■Battery caution

RDANGER! Use and charge only specified Icom battery

pack with Icom radios or Icom charger. Only Icom battery

pack is tested and approved for use and charge with Icom ra-

dios or Icom charger. Using third-party or counterfeit battery

packs or charger may cause smoke, ﬁre, or cause the battery

to burst.

DBattery caution

RDANGER! 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 pres-

sure. 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.

RDANGER! 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 perfor-

mance or shorten battery life.

RDANGER! DO NOT expose the battery to rain, snow, sea-

water, or any other liquids. Do not charge or use a wet bat-

tery. If the battery gets wet, be sure to wipe it dry before

using. The battery by itself is not waterproof.

RDANGER! NEVER incinerate a used battery pack since

internal battery gas may cause them to rupture or may cause

an explosion.

RDANGER! 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.

RDANGER! Use the battery only with the transceiver for

which it is speciﬁed. Never use a battery with any other equip-

ment, or for any purpose that is not speciﬁed in this instruction

manual.

RDANGER! If ﬂuid from inside the battery gets in your eyes,

blindness can result. Rinse your eyes with clean water, with-

out rubbing them, and see a doctor immediately.

Misuse of Lithium-Ion batteries may result in the follow-

ing hazards: smoke, ﬁre, or the battery may rupture.

Misuse can also cause damage to the battery or degra-

dation of battery performance.

8BATTERY CHARGING

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 distrib-

utor.

WARNING! Immediately wash, using clean water, any part of

the body that comes into contact with ﬂuid from inside the bat-

tery.

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 (–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.

CAUTION! Shorter battery life could occur if the battery is left

fully charged, completely discharged, or in an excessive tem-

perature 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 battery indicator shows half-

capacity ( ), then keep it safely in a cool dry place with

the temperature between –20˚C to +20˚C (–4˚F to +68˚F).

DCharging caution

RDANGER! NEVER charge the battery pack in areas with

extremely high temperatures, such as near ﬁres or stoves, in-

side a sun-heated car, or in direct sunlight. In such environ-

ments, 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 bat-

tery charger beyond the speciﬁed time for charging. If the bat-

tery 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 rup-

ture.

WARNING! NEVER insert the battery and transceiver (bat-

tery 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-

fied temperature range: ±0˚C to +40˚C (+32˚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 performance or bat-

tery life may be reduced.
