Built tough to withstand the punishing marine environment, the IC-M21 meets JIS water resistant specification
grade 7 while using BP-223 or BP-224.
☞ Dual watch and tri-watch functions*
Convenient functions which allow you to monitor the distress channel (Ch 16) while receiving a channel of your
choice—dual watch; or monitor the distress channel and
another channel while receiving a channel of your
choice—tri-watch.
*This function may not be available depending on version.

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.
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 vertical.
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 below –15°C or above +55°C.
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.
iii
BE CAREFUL! The transceiver’s right-side panel will
become hot when operating continuously for long periods.
BE CAREFUL! The IC-M21 employs water resistant
construction, which corresponds to JIS water resistant specification, grade 7 (1 m; 3 ft depth for 30 min.). However, once
the transceiver has been dropped, water resistant cannot be
guaranteed due to the fact that the transceiver may be
cracked, or the water resistant 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.
Versions of the IC-M21 which display the “CE”
symbol on the serial number seal, comply with
the essential requirements of the European Radio
and Telecommunication Terminal Directive 1999/5/EC.
This warning symbol indicates that this equipment operates in non-harmonised frequency bands and/or may be subject to licensing conditions in the country of use. Be sure to
check that you have the correct version of this radio or the
correct programing of this radio, to comply with national licensing requirement.

DECLARATION OF CONFORMITY
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 lawfully 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 includes 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 regulations 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.
