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 verti-
cal.
BE CAREFUL! The IC-M90 employs waterproof con-
struction, which corresponds to JIS waterproof specification,
Grade 7 (1 m; 3 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-225 or BP-223. Such a connection will ruin the
transceiver.
For U.S.A. only
CAUTION: Changes or modifications to this device, not
expressly approved by Icom Inc., could void your authority to
operate this device under FCC regulations.
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): MARINE, –30°C (–22°F) or above +60°C
(+140°F): LMR.
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) OPERATOR’S 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-M90 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 occupational 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.

SCAN OPERATION
5
I Scan types
Scanning is an efficient 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 alert” and “Auto scan” functions are
available for scanning. These functions can be activated si-
multaneously, 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 charging
I Battery cautions
Prior to using the transceiver for the first time, the battery
pack must be fully charged for optimum life and operation.
CAUTION! NEVER insert battery pack/transceiver
(with the battery pack attached) with wet or soiled into the
charger. This may result in corrosion of the charger terminals
or damage to the charger. The charger is not waterproof and
water can easily get into it.
CAUTION: To avoid damage to the transceiver, turn the
power OFF while charging.
• Recommended temperature range for charging:
+10°C to +40°C (+50°F to +104°F)
• Use the specified chargers (BC-158, BC-119N and
BC-121N). NEVER use another manufacture’s charger.
• Use the supplied AC adapter for the BC-158. NEVER use
another manufacture’s adapters.
NEVER incinerate used battery packs. Internal battery gas
may cause an explosion.
NEVER immerse 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).
NEVER connect DC power to the battery case when in-
stalling Alkaline batteries. Such a connection will damage
the transceiver.
NEVER short the terminals of the battery pack. Also, cur-
rent may flow into nearby metal objects, such as a necklace,
etc. Therefore, be careful when carrying in a pocket, back-
pack or handbag, and when placing the radio near metal ob-
jects.
D Recycling information
The product that you have purchased contains a
rechargeable battery. The battery is recyclable.
At the end of its life, under various state and
local laws, it may be illegal to dispose of this bat-
tery into the municipal waste stream. Call 1-800-
822-8837 for battery recycling options in your
area or contact your dealer.
If your battery pack seem 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
batteries still do not retain a charge (or very little), new bat-
tery pack must be purchased.
Turn the transceiver OFF when charging an attached bat-
tery pack. Otherwise, the battery pack may not become full-
charging or may not charge properly.
