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 tested and complies with the FCC RF exposure limits for
“Occupational Use Only”. In addition, your Icom radio complies with the follow-
ing 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 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.
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:
• DO NOT operate the radio without a proper antenna at-
tached, as this may damaged the radio and may also cause
you to exceed FCC RF exposure limits. A proper antenna is the antenna sup-
plied with this radio by the manufacturer or antenna specifically authorized by
the manufacturer for use with this radio.
CAUTION
WARNING
• 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 use Icom authorized accessories (antennas, batteries, belt clips,
etc.). Use of unauthorized accessories can cause the FCC RF exposure
compliance requirements to be exceeded.
• 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 25 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.

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.
IC-M88-draft.qxd 02.9.26 2:44 PM Page iv (1,1)
CAUTIONS
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 very close to, or touching 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 verti-
cal.
NEVER connect the transceiver to a power source other
than the BP-223 or BP-224. Such a connection will ruin the
transceiver.
AVOID using or placing the transceiver in direct sunlight or
in areas with temperatures Marine: below –20°C (–4°F) or
above +60°C (+140°F), LMR: below –30°C (–22°F) or above
+60°C (+140°F).
KEEP the transceiver out of the reach of children.
KEEP the transceiver at least 0.9 meter (3.0 ft) away from
your vessel’s magnetic navigation compass.
iv
BE CAREFUL! The transceiver’s right-side panel will
become hot when operating continuously for long periods.
BE CAREFUL! The IC-M88 employs waterproof con-
struction, which corresponds to JIS waterproof specification,
grade 7 (1 m; 3 ft depth for 30 min.). However, once the trans-
ceiver has been dropped, waterproofing cannot be guaran-
teed 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.

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-M88 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.

5SCAN 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, weather alert and an automatic scan start func-
tion is available for standby convenience. (pgs. 16)
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. 17)
NORMAL SCAN
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.

9BATTERY CHARGING
■Battery charging
Prior to using the transceiver for the first time, the battery
pack must be fully charged for optimum life and operation.
CAUTION: To avoid damage to the transceiver, turn it OFF
while charging.
•Recommended temperature range for charging:
+10°C to +40°C (+50°F to +104°F)
•Use the supplied charger (BC-152) only. NEVER use an-
other manufacturer’s charger.
■Caution
NEVER incinerate used battery packs. Internal battery gas
may cause an explosion.
NEVER immerse the battery pack in water. If the battery pack
becomes wet, be sure to wipe it dry immediately (particularly
the battery terminals) BEFORE attaching it to the transceiver.
Otherwise, the terminals will become corroded, or cause con-
nection failure, etc.
NEVER short the terminals of the battery pack. Also, current
may flow into nearby metal objects, such as a necklace, etc.
Therefore, be careful when carrying with, or placing near
metal objects, carrying in handbags, etc.
AVOID leaving the battery pack in a fully charged, or com-
pletely discharged condition for long time. It causes shorter
battery life. In case of leaving the battery pack unused for a
long time, it must be kept safely after discharge, or use the
battery until the battery indicator shows the middle level, then
remove it from the transceiver.
If your battery pack seems to have no capacity even after
being charged, completely discharge it by leaving the power
ON overnight. Then, fully charge the battery pack again. If the
battery pack still does not retain a charge (or very little), a
new battery pack must be purchased.
Recommendation:
Charge the supplied battery pack for a maximum of
up to 8 hours. Li-Ion batteries are different from Ni-
Cd batteries in that it is not necessary to completely
charge and discharge them to prolong the battery life.
Therefore, charge the battery in intervals, and not for
extended periods is recommended.

5 ×AA(R6) size alkaline batteries as illustrated below.
qHook on your finger to the
latch, and open the cover in
the direction (q) of the arrow.
(Fig.1)
wThen, install 5 ×AA(R6) size
alkaline batteries. (Fig.2)
• Be sure to observe the cor-
rect polarity.

the batteries.
eClose the cover with fitting in
the direction (w) of the arrow
and lock the latch e. (Fig.1)
• Be sure to the gasket and
the ribbon are not out of
the battery case.
CAUTION:
•When installing batteries, make sure they are all the
same brand, type and capacity. Also, do not mix new
and old batteries together.
•Keep battery contacts clean. It’s a good idea to clean
battery terminals once a week.
