WARNING
Your Icom radio generates RF electromagnetic energy dur-
ing 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 tested and complies with the FCC and IC 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 electro-
magnetic energy levels and evaluation of such levels for exposure to humans:
• FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compli-
ance with FCC Guidelines for Human Exposure to Radio Frequency Elec-
tromagnetic 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.
• The following accessories are authorized for use with this product. Use
of accessories other than those specified may result in RF exposure lev-
els exceeding the FCC and IC requirements for wireless RF exposure:
Swivel Belt Clip (MB-86), Rechargeable Li-ion Battery Pack (BP-227UL),
and Speaker-microphone (HM-168IS).
CAUTION
To ensure that your expose to RF electromagnetic en-
ergy is within the FCC and IC allowable limits for occu-
pational 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 and IC 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 and
IC RF exposure compliance requirements to be exceeded. The radio is
transmitting when the transmit icon is displayed. 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 35 when attaching the radio to your belt, etc., to ensure FCC and IC
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 and IC 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.
SAFETY TRAINING INFORMATION

RDANGER! NEVER short the terminals of the bat-
tery pack. Also, current may flow into metal objects such as
a key, so be careful when placing the battery packs (or the
transceiver) in bags, and so on. Simply carrying with or plac-
ing 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! Use and charge only specified Icom bat-
tery packs with Icom transceivers or Icom chargers. Only
Icom battery packs are tested and approved for use with Icom
transceivers or charged with Icom chargers. Using third-party
or counterfeit battery packs or chargers may cause smoke,
fire, or cause the battery to burst.
RDANGER! Use only HM-168IS speaker microphone.
Only HM-168IS is tested and approved for use with the trans-
ceiver. Using third-party or counterfeit microphone may pre-
sent a risk of fire or explosion.
RDANGER! NEVER operate the transceiver near
unshielded electrical blasting caps or in an explosive atmo-
sphere.
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.

source other than the products specified by Icom. Such a
connection will ruin the transceiver.
CAUTION: MAKE SURE the flexible antenna, bat-
tery pack and jack cover are securely attached to the trans-
ceiver, and that the antenna and battery pack are dry before
attachment. Exposing the inside of the transceiver to dust or
water will result in serious damage 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.
DO NOT place or leave the transceiver in direct sunlight
or in areas with temperatures below –20°C (–4°F) or above
+60°C (+140°F): Marine, below –30°C (–22°F) or above
+60°C (+140°F): LMR.
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 mod-
ification.

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 law-
fully 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 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 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 regulations.
NOTE: Even though the IC-M88 is capable of operation on
VHF marine channels 3, 21, 23, 61, 64, 81, 82 and 83, ac-
cording to FCC regulations these simplex channels cannot
be lawfully used by the general public in USA waters.
