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 hazards, and the ways to minimize such hazards. This radio is
NOT intended for use by the “General Population” in an uncontrolled 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 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-
109), Rechargeable Li-Ion Battery Pack (BP-252) and Alkaline Battery
Case (BP-251).
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
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 manufacturer 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 exposure 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 exposure compliance requirements are not exceeded. To provide the recipients 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.
ii
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 vessel.
4. “LOCATED AT .....................” (your position)
5. The nature of the distress and assistance required.
6. Any other information which might facilitate

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 (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-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 waterproof 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.
After exposure to water, clean the battery contacts thoroughly
with fresh water and dry them completely to remove any
water or salt residue.

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.
NOTE: Even though the IC-M34 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 U.S.A.

SCAN OPERATION
5
■ 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 functions are
available for standby convenience. These functions can be
activated simultaneously, depending on the setting in set
mode. (pgs. 18, 19)
Set the TAG channels (scanned channels) before scanning.
Clear any 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 sequence while monitoring Channel 16. When a signal is detected on Channel 16, scan pauses until the signal disappears; when a signal is detected on a channel other than
Channel 16, scan becomes dualwatch until the signal disappears.

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 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, sea-
water, 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 them to rupture or may cause
an explosion.
R DANGER! NEVER solder the battery terminals, or NEVER
