IN CASE OF EMERGENCY
NOTE
If your vessel requires assistance, contact other vessels and
the Coast Guard by sending a distress call on Channel 16.
A WARNING STICKER is supplied with the transceiver.
To comply with FCC regulations, this sticker must be affixed in
such a location as to be readily seen from the operating controls of the radio. Make sure the chosen location is clean and
dry before applying the sticker.
USING CHANNEL 16
DISTRESS CALL PROCEDURE
1. “MAYDAY MAYDAY MAYDAY.”
2. “THIS IS ...............” (name of vessel)
3. Your call sign or other indication of the vessel (AND 9digit DSC ID if you have one).
4. “LOCATED AT ...............” (your position)
5. The nature of the distress and assistance required.
6. Any other information which might facilitate the rescue.
Or, transmit your distress call using digital selective calling on
Channel 70.
USING DIGITAL SELECTIVE CALLING (Ch 70)
DISTRESS CALL PROCEDURE
1. While lifting up the key cover, push and hold
[DISTRESS] for 5 sec. until you hear 5 short beeps
change to one long beep.
2. Wait for an acknowledgment from a coast station.
• Channel 16 is automatically selected.
3. Push and hold [PTT], then transmit the appropriate
information as listed above.

RADIO OPERATOR WARNING
Icom requires the radio operator to meet the
FCC Requirements for Radio Frequency Exposure. An omnidirectional antenna with gain not
greater than 9 dBi must be mounted a minimum
W ARN ING
of 5 meters (measured from the lowest point of
the antenna) vertically above the main deck and
all possible personnel. This is the minimum safe separation
distance estimated to meet all RF exposure compliance requirements. This 5 meter distance is based on the FCC Safe
Maximum Permissible Exposure (MPE) distance of 3 meters
added to the height of an adult (2 meters) and is appropriate
for all vessels.
For watercraft without suitable structures, the antenna must
be mounted so as to maintain a minimum of 1 meter vertically
between the antenna, (measured from the lowest point of the
antenna), to the heads of all persons AND all persons must
stay outside of the 3 meter MPE radius.
Do not transmit with radio and antenna when persons are
within the MPE radius of the antenna, unless such persons
(such as driver or radio operator) are shielded from antenna
field by a grounded metallic barrier. The MPE Radius is the
minimum distance from the antenna axis that person should
maintain in order to avoid RF exposure higher than the allowable MPE level set by FCC.
iii
FAILURE TO OBSERVE THESE LIMITS MAY ALLOW
THOSE WITHIN THE MPE RADIUS TO EXPERIENCE RF
RADIATION ABSORPTION WHICH EXCEEDS THE FCC
MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMIT.
IT IS THE RESPONSIBILITY OF THE RADIO OPERATOR
TO ENSURE THAT THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS ARE OBSERVED AT ALL TIMES DURING
RADIO TRANSMISSION. THE RADIO OPERATOR IS TO
ENSURE THAT NO BYSTANDERS COME WITHIN THE
RADIUS OF THE MAXIMUM PERMISSIBLE EXPOSURE
LIMITS.
Determining MPE Radius
THE MAXIMUM PERMISSIBLE EXPOSURE (MPE) RADIUS HAS BEEN ESTIMATED TO BE A RADIUS OF
ABOUT 3M PER OET BULLETIN 65 OF THE FCC.
THIS ESTIMATE IS MADE ASSUMING THE MAXIMUM
POWER OF THE RADIO AND ANTENNAS WITH A MAXIMUM GAIN OF 9dBi ARE USED FOR A SHIP MOUNTED
SYSTEM.

PRECAUTIONS
RWARNING! NEVER connect the transceiver to an AC
BE CAREFUL! The transceiver rear panel will become
outlet. This may pose a fire hazard or result in an electric
shock.
hot when operating continuously for long periods.
Place the transceiver in a secure place to avoid inadvertent
use by children.
CAUTION: Changes or modifications to this device, not expressly approved by Icom Inc., could void your authority to
operate this device under FCC regulations.
NEVER connect the transceiver to a power source of more
than 16 V DC or use reverse polarity. This will ruin the transceiver.
NEVER cut the DC power cable between the DC plug and
fuse holder. If an incorrect connection is made after cutting,
the transceiver may be damaged.
NEVER place the transceiver where normal operation of the
vessel may be hindered or where it could cause bodily injury.
KEEP the transceiver at least 3.3 ft (1 m) away from the
ship’s navigation compass.
DO NOT use or place the transceiver in areas with temperatures below –4°F (–20°C) or above +140°F (+60°C) or, in
areas subject to direct sunlight, such as the dashboard.
AVOID the use of chemical agents such as benzine or alcohol when cleaning, as they may damage the transceiver
surfaces.
BE CAREFUL! The transceiver and optional HM-157
COMMANDMIC II™
employ waterproof construction, which corresponds to IPX waterproof specification, Grade 7
(1 m/30 min.). However, once the transceiver or microphone
has been dropped, waterproofing cannot be guaranteed due
to the fact that the case may be cracked, or the waterproof
seal damaged, etc.

OPERATING RULES
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 signals are prohibited and punishable by law.
D PRIVACY
• Information overheard but not intended for you cannot lawfully be used in any way.
(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 or 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.
Keep a copy of the current government rules and regulations
handy.
• Indecent or profane language is prohibited.
D RADIO LICENSES
(1) SHIP STATION LICENSE
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 application. This
government-issued license states the call sign which is your
craft’s identification for radio purposes.
Radio license for boaters (U.S.A. only)
The Telecommunications Act of 1996 permits recreational
boaters to have and use a VHF marine radio, EPIRB, and
marine radar without having an FCC ship station license.
Boaters traveling on international voyages, having an HF
single sideband radiotelephone or marine satellite terminal, or required to carry a marine radio under any other
regulation must still carry an FCC ship station license. For
further information, see the FCC Ship Radio Stations Fact
Sheet.

BASIC OPERATION
■ Channel selection
ï Channel 16
ï Channel 9 (Call channel)
Channel 16 is the distress and safety channel. It is used for
establishing initial contact with another station and for emergency communications. Channel 16 is monitored during both
dualwatch and tri-watch. While standing by, you must monitor
Channel 16.
Each regular channel group has a separate leisure-use call
channel. The call channel is monitored during tri-watch. The
call channels can be programmed (p. 8) and are used to store
your most often used channels in each channel group for
quick recall.
➥ Push [16•9] momentarily to select Channel 16.
➥ Push [CH/WX•DUAL] to return to the condition before selecting Channel 16, or push [Y] or [Z] to select operating channel.
➥ Push [16•9] for 1 sec. to select the call channel of the selected channel group.

SCAN 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.
When the weather alert function is turned ON, the previously
selected (used) weather channel is also checked while scanning. (p. 32)
PRIORITY SCAN
CH 01
CH 02
CH 16
CH 05
CH 03
CH 04
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.
10
Choose priority or normal scan in set mode. (p. 31)
NORMAL SCAN
CH 01
CH 06
Set the tag channels (scanned channel) before scanning.
Clear the tag channels which inconveniently stop scanning,
such as those for digital communication use. (Refer to right
page for details.)
CH 02
CH 06
CH 03
CH 05
CH 04
Normal scan, like priority scan, searches through all tag
