Your Icom radio generates RF electromagnetic energy during
transmit mode. This radio is designed for and classified as
“General Population Use” in an uncontrolled environment.
This radio has been evaluated for compliance at the distance
of 2.5 cm (1 inch) with the FCC RF exposure limits for “
Gen-
eral Population Use
”. 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 01-01 Supplement C, Evaluating Compli-
ance with FCC Guidelines for Human Exposure to Radio Frequency
Electromagnetic Fields.
• American National Standards Institute (C95.1-2005), IEEE Standard
for Safety Levels with Respect to Human Exposure to Radio Frequency
Electromagnetic Fields, 3 kHz to 300 GHz.
• American National Standards Institute (C95.3-2002), IEEE Recom-
mended Practice for the Measurement of Potentially Hazardous Electro-
magnetic 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 Bat-
tery Case (BP-251).
To ensure that your expose to RF electromagnetic en-
ergy is within the FCC allowable limits for general popu-
lation use, always adhere to the following guidelines:
•
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 ex-
posure 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 expo-
sure compliance requirements to be exceeded. The radio is transmitting
when the “transmit indicator” appears on the LCD. 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
p. 28 when attaching the radio to your belt, etc., to ensure FCC RF
exposure compliance requirements are not exceeded. To provide the re-
cipients 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.

IN CASE OF EMERGENCY RECOMMENDATION
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
required.
6. Any other information which might facilitate
the rescue.
CLEAN THE TRANSCEIVER THOROUGHLY WITH FRESH
WATER after exposure to saltwater, and dry it before opera-
tion. Otherwise, the transceiver's keys, switches and control-
lers may become unusable due to salt crystallization.
NOTE: DO NOT wash the transceiver in water if there is any
reason to suspect the waterproof protection may not be ef-
fective. For example, in cases where the battery pack rubber
seal is damaged, the transceiver/battery pack is cracked or
broken, or has been dropped, or when the battery pack is
detached from the transceiver.

FOREWORD
Thank you for purchasing this Icom radio. The IC-M36 vhf
marine transceiver is designed and built with Icom’s state of
the art technology and craftsmanship. With proper care this
radio should provide you with years of trouble-free operation.
IMPORTANT
READ ALL INSTRUCTIONS carefully and com-
pletely before using the transceiver.
SAVE THIS INSTRUCTION MANUAL—This
instruction manual contains important operating instructions
for the IC-M36.
EXPLICIT DEFINITIONS
WORD DEFINITION
RWARNING Personal injury, fire hazard or electric
shock may occur.
CAUTION Equipment damage may occur.
NOTE
If disregarded, inconvenience only. No risk
of personal injury, fire or electric shock.
FEATURES
☞ Floating on water
The transceiver floats on fresh or salt
water even when the supplied acces-
sories are attached.
• When a third-party battery pack, strap,
antenna, etc. is used, it may sink.
• The battery contacts may be prone to
rust if the transceiver is kept floating on
the water.
☞ Clear voice boost
The transceiver has the noise detection function which
enables automatic volume adjustment and the volume
loud function that enables you to maximize the volume
level instantly to provide clear communication in the
noisy marine environments.
☞ Noise cancelling microphone
The sub-microphone on the rear panel inverts the phase
and cancels out the ambient noise from the main micro-
phone. As a result, the transceiver can reduce the influ-
ence of the background noise (particularly treble noise)
on the transmitted signal.
• The noise cancellation can produce no effect according to con-
ditions such as loudness and type of noise, or the position and
distance between the noise source and the microphone, etc.
• The noise cancellation does not work when an optional exter-
nal speaker-microphone is connected.

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 transmit-
ting. The transceiver will perform best if the microphone is
5 to 10 cm (2 to 4 inches) away from the lips and the trans-
ceiver 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.
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).
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 meets IPX7* require-
ments for waterproof protection. However, once the trans-
ceiver has been dropped, waterproof protection cannot be
guaranteed because of possible damage to the transceiver's
case or the waterproof seal.
* Only when the BP-251 (option) or BP-252, flexible antenna, [SP
MIC] cap is attached.
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 dam-
age to the transceiver.
After exposure to water, clean the battery contacts thor-
oughly with fresh water and dry them completely to remove
any water or salt residue.

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 or kept with the operator. Only a licensed radio op-
erator may operate a transceiver.
However, non-licensed individuals may talk over a trans-
ceiver 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 IC-M36 is capable of operation
on VHF marine channels 3, 21, 23, 61, 64, 81, 82 and
83, according to FCC regulations these simplex chan-
nels cannot be lawfully used by the general population in
U.S.A. waters.

■ Battery caution
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.
R DANGER! 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
radios or Icom charger. Using third-party or counterfeit bat-
tery packs or charger 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 perfor-
mance or shorten battery life.
R DANGER! DO NOT expose the battery to rain, snow,
saltwater, or any other liquids. Never 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 modify the battery pack. This may cause heat gen-
eration, 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 described in this
instruction manual.
R DANGER! If fluid 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.

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 dis-
tributor.
WARNING! Immediately wash, using clean water, any part
of the body that comes into contact with fluid from inside the
battery.
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 specific 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 specific 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
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 envi-
ronments, the safety/protection circuit in the battery will acti-
vate, causing the battery to stop charging.
WARNING! DO NOT charge or leave the battery in the bat-
tery charger beyond the specific time for charging. If the
battery is not completely charged by the specific time, stop
charging and remove the battery from the battery charger.
Continuing to charge the battery beyond the specific time
limit may cause a fire, overheating, or the battery may rup-
ture.
WARNING! NEVER insert the 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
specific 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 specific temperature range. Additionally, battery perfor-
mance or battery life may be reduced.
