EXPLICIT DEFINITIONS
WORD DEFINITION
RDANGER Personal death, serious injury or an
explosion may occur.
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, and so on, 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 a noise detection function which en-
ables automatic volume adjustment, and the volume loud
function that enables you to maximize the volume level
instantly to provide clear communication in the noisy ma-
rine 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.

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 IN A BOWL
OF FRESH WATER after exposure to saltwater, and dry
it before operating. Otherwise, the transceiver’s keys,
switches, and controllers may become unusable, due to salt
crystallization, and/or the charging terminals of the battery
pack may corrode.
NOTE: If the transceiver’s waterproof protection appears
defective, carefully clean it with a soft, damp (fresh water)
cloth, then dry it before operating.
The transceiver may lose its waterproof protection if the
case, jack cap, or connector cover is cracked or broken,
the transceiver has been dropped, or the battery pack is
detached.
Contact your Icom distributor or your dealer for advice.

FCC INFORMATION
This equipment has been tested and found to comply with the
limits for a Class A digital device, pursuant to part 15 of the
FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment
is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instruc-
tion manual, may cause harmful interference to radio com-
munications.
Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be re-
quired to correct the interference at his own expense.
PRECAUTIONS
RDANGER! NEVER short terminals of the battery pack.
Also, current may flow into nearby metal objects such as a key,
so be careful when placing the battery packs (or the transceiver)
in handbags, and so on. Simply carrying with or placing near
metal objects such as a key, and so on may cause shorting. This
may damage not only the battery pack, but also the transceiver.
RDANGER! NEVER use and charge other than the speci-
fied 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
battery packs or charger may cause smoke, fire, or cause the
battery to burst.
RDANGER! NEVER operate the transceiver near un-
shielded electrical blasting caps or in an explosive atmosphere.
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 an-
tenna is closer than 2.5 cm (1 inch) 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.
iii

iv
CAUTION: DO NOT attach the battery unless the flexible
antenna, battery pack and jack cover are securely attached to
the transceiver. Confirm that the antenna and battery pack are
dry before attaching. Exposing the inside of the transceiver to
dust or water can cause 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.
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 operate or place the transceiver in direct sunlight or
in areas with temperatures below –20°C (–4°F) or above +60°C
(+140°F).
DO NOT use harsh solvents such as Benzine or alcohol when
cleaning, as they will damage the transceiver surfaces.
DO NOT push [PTT] when not actually intending to transmit.
DO NOT modify the transceiver. The transceiver warranty does
not cover any problems caused by unauthorized modifications.
PLACE the transceiver in a secure place to avoid inadvertent
use by unauthorized persons.
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 of time.
BE CAREFUL! The transceiver meets IPX7* 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.
* Only when the BP-251 (option) or BP-252, flexible antenna, [SP
MIC] cap is attached.
MAKE SURE to turn OFF the transceiver power before con-
necting or disconnecting the supplied or optional accessory.
Icom is not responsible for the destruction, damage to, or per-
formance of any Icom or non-Icom equipment, if the malfunc-
tion is because of:
• Force majeure, including, but not limited to, fires, earthquakes,
storms, floods, lightning, other natural disasters, disturbanc-
es, riots, war, or radioactive contamination.
• The use of Icom transceivers with any equipment that is not
manufactured or approved by Icom.

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 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 channels
cannot be lawfully used by the general population in USA
waters.

SCAN OPERATION

■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
simultaneously activated, depending on the setting in the set
mode. (pp. 18, 19)
Set the TAG channels (scanned channels) before scanning.
Clear the TAG for unwanted channels which inconveniently
stop scanning, such as those for digital communications.
(p. 15)
Choose the scan type from "Priority" or "Normal" in the
set mode. (p. 18)
PRIORITY SCAN
WX*
CH 01
CH 16
CH 02
CH 05 CH 04
CH 03
Previously selected weather channel.
(when the weather alert function is activated)
*
Priority scan searches through all TAG channels in se-
quence 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 sig-
nal disappears.
NORMAL SCAN
CH 01 CH 02
WX*
CH 05 CH 04
CH 03
Previously selected weather channel.
(when the weather alert function is activated)
*
Normal scan, like priority scan, searches through all TAG
channels in sequence. However, unlike priority scan,
Channel 16 is not checked unless Channel 16 is set as a
TAG channel.
