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.  
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.  
USING CHANNEL 16  
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 transceiver/battery pack is cracked  
or broken, or has been dropped, or when the battery pack is de-  
tached from the transceiver.  
DISTRESS CALL PROCEDURE  
1. “MAYDAY MAYDAY MAYDAY.”  
2. “THIS IS ...........................” (name of vessel)  
3. Say your call sign or other indication of the  
vessel.  
4. “LOCATED AT .....................” (your position)  
5. State the nature of the distress and assis-  
tance required.  
6. Give any other information which might facil-  
itate the rescue.

PRECAUTION  
RWARNING! NEVER connect the transceiver to an  
AC outlet. This may pose a fire hazard or result in an electric  
shock.  
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.  
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.  
BE CAREFUL! The IC-M72 employs submersible con-  
struction (1.5 m; 4.9 ft depth for 30 min.). However, once the  
transceiver has been dropped, waterproofing cannot be guar-  
anteed due to the fact that the transceiver may be cracked,  
or the waterproof seal damaged, etc.  
NEVER connect the transceiver to a power source other  
than the BP-245. Such a connection will ruin the transceiver.  
For the U.S.A. only  
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).  
CAUTION: Changes or modifications to this device, not  
expressly approved by Icom Inc., could void your authority to  
operate this device under FCC regulations.  
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.

OPERATING RULES  
1
(2) OPERATORS LICENSE  
D Priorities  
1
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.  
• 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.  
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.  
• You must monitor Channel 16 when you are not operating  
on another channel.  
• False or fraudulent distress calls are prohibited under law.  
However, non-licensed individuals may talk over a transceiver  
if a licensed operator starts, supervises, ends the call and  
makes the necessary log entries.  
D Privacy  
• Information overheard but not intended for you cannot law-  
fully be used in any way.  
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.  
• 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.  
NOTE: Even though the IC-M72 is capable of operation  
on VHF marine channels 3, 21, 23, 61, 64, 81, 82 and 83,  
according to FCC regulations these simplex channels can-  
not be lawfully used by the general public in USA waters.  
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.

BASIC OPERATION  
I Channel naming  
I VOX function  
The IC-M72 has a capability to assign up to 10-character  
channel names or comments for each operating channel, in-  
cluding each weather channel. This provides easy recogni-  
tion of channel usage, or station names, etc.  
NOTE: An optional headset and optional headset adapter  
are required for the VOX operation.  
The VOX function (voice operated transmission) starts transmit-  
ting when you speak into the headsets microphone. There is  
no need to push [PTT]. The IC-M72 automatically returns to  
receive mode when you stop talking.  
When shipped from the factory, the IC-M72 is programmed  
with default names for each VHF marine channel. These de-  
faults can be changed, if desired.  
You may replace the factory-set opening comment with a  
comment of your own. The opening comment appears each  
time the IC-M72 is powered ON. The comment may be up to  
16 characters long.  
Push and hold [  
], then push [H/LLOCK] to turn the  
VOX function ON or OFF while connecting the headset  
and optional headset adapter to [SP MIC] connector.  
• “VOXappears on the LCD while the VOX function turns ON.  
The VOX gain and VOX delay can be set on the SET mode. (p. 22)

away from the speaker housing (water that might otherwise muf-  
e the sound coming from the speaker). The IC-M72 emits a vi-  
brating noise when this function is being used.

SCAN OPERATION  
5
I Scan types  
Scanning is an efcient way to quickly locate signals over a  
wide frequency range. The transceiver has a priority scan set-  
ting and normal scan setting.  
Set the TAG channels (scanned channel) before scanning.  
Clear those TAG channels which are not needed or inconve-  
niently stop scanning, such as digital communications.  
In addition, the Weather alertand Auto scanfunctions are  
also available for scanning. These functions can be activated  
simultaneously, depending on the settings on the SET mode.

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.  
Normal scan, like priority scan, searches through all TAG  
channels in sequence. However, unlike priority scan, Chan-  
nel 16 is not checked unless Channel 16 is set as a TAG  
channel.

I Battery cautions  
R DANGER! DO NOT expose the battery to rain, snow,  
seawater, 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.  
Misuse of Lithium-ion batteries may result in the follow-  
ing hazards: smoke, re, or battery rupture.  
Misuse can also cause other battery damage or degra-  
dation of battery performance.  
R DANGER! NEVER incinerate a used battery pack since  
internal battery gas may cause a rupture or explosion.  
R DANGER! Use and charge only specified Icom battery  
pack with Icom transceiver. Only Icom battery pack is tested  
and approved for use with Icom transceiver. Using third-  
party or counterfeit battery packs may cause smoke, re, or  
cause the battery to burst.  
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  
re.  
7
8
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 specied in this in-  
struction manual.  
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 re.  
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.  
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.  
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 re.  
Excessive temperatures may also degrade battery perfor-  
mance or shorten battery life.  
WARNING! Immediately wash, using clean water, any part  
of the body that comes into contact with uid from inside the  
battery.

BATTERY CHARGING  
D Charging caution  
WARNING! NEVER put the battery in a microwave oven,  
high-pressure container, or in an induction heating cooker.  
This could cause overheating, a re, or cause the battery to  
rupture.  
R DANGER! NEVER charge the battery pack in areas with  
extremely high temperatures, such as near res 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.  
CAUTION! Always use the battery within the specied 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 specied temperature  
range will reduce the batterys performance and battery life.  
Please note that the specied temperature range of the bat-  
tery may exceed that of the transceiver. In such cases, the  
transceiver may not work properly because it is out of its op-  
erating temperature range.  
WARNING! DO NOT charge or leave the battery in the bat-  
tery charger beyond the specified time for charging. If the  
battery is not completely charged by the specied time, stop  
charging and remove the battery from the battery charger.  
Continuing to charge the battery beyond the specied time  
limit may cause a re, overheating, or the battery may rup-  
ture.  
CAUTION! Shorter battery life could occur if the battery is  
left fully charged, completely discharged, or in an excessive  
temperature environment (above +45˚C; +113˚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 battery indicator  
shows half-capacity, then keep it safely in a cool dry place  
with the temperature between 20˚C to +25˚C (4˚F to  
+77˚F).  
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 spec-  
ied temperature range: 0˚C to +45˚C (+32˚F to +113˚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 perfor-  
mance or battery life may be reduced.
