If your vessel requires assistance, contact other vessels and
the Coast Guard by sending a distress call on Ch 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 like as follows. Make sure the chosen location is clean and dry before applying the sticker. (p. 46)
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.

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.
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.
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.
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.
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.

OPERATING RULES
◊ 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.
◊ PRIVACY
• Information overheard but not intended for you cannot lawfully be used in any way.
• Indecent or profane language is prohibited.
(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.
◊ 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
■ Optional voice scrambler operation
◊ Activating the scrambler
◊ Programming scrambler codes
The optional voice scrambler provides private communications. In order to receive or send scrambled transmissions
you must first activate the scrambler function. To activate the
function, an optional UT-112 is necessary. See p. 45 for setting the scrambler unit. Ask your dealer for details.
There are 32 codes (1 to 32) available for programming when
the optional UT-112 is installed. In order to understand one
another, all transceivers in your group must have the same
scramble code. This function may not be available depending on dealer setting.
The scrambler function automatically turns OFF when
channel 16 or 70 is selected.
q Turn power OFF.
w While pushing [16•9], turn power ON to enter set mode.
e After the display appears, release [16•9].
r Rotate [CHANNEL] to select the “Scrambler Code,”
push [ENT].
t Rotate [CHANNEL] to select desired scrambler code.
y Push [ENT] to set and exit the scrambler code item.
u Rotare [CANNEL] to select “Exit,” then push [ENT] to
exit set mode.
q Select an operating channel other than channel 16 and 70.
w Push [F] then [0 SCRM] to toggle an optional scrambler
function ON or OFF.
• “SCRAM” appears.
e To turn the scrambler function OFF, repeat step w.

SCAN OPERATIONS
■ 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 in use, the selected
weather channel is checked while scanning. (p. 43)
PRIORITY SCAN
CH 02
CH 16
CH 05
CH 01
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.
14
Choose priority or normal scan in set mode. (p. 43)
NORMAL SCAN
CH 01
CH 06
Set the tag channels (scanned channel) before scanning.
Clear the tag channels which inconveniently stop scanning,
such as digital communication use.
CH 02
CH 06
CH 03
CH 05
CH 04
Normal scan, like priority scan, searches through all tag
channels in sequence. However, unlike priority scan, channel 16 is not checked unless channel 16 is set as a tag
channel.
SCAN OPERATION
■ Setting tag channels
■ Starting a scan
For more efficient scanning, add desired channels as tag
channels or clear tag channels for unwanted channels. Channels set as non-tag channels will be skipped during scanning.
Tag channels can be assigned to each channel group
(U.S.A., International, Canada) independently.
Set scan type (priority or normal scan) and scan resume timer
in advance using set mode. (p. 43)
q While pushing [H/L], push [CH/WX•U/I/C] once or more
times to select the desired channel group, if desired.
w Select the desired channel to set as a tag channel.
e Push [F] then [5 TAG] to set the displayed channel as a
tag channel.
q Set tag channels as described at left.
w Make sure the squelch is closed to start a scan.
e While pushing [H/L], push [CH/WX•U/I/C] once or more
times to select the desired channel group, if desired.
r Push [F] then [4 SCN] to start priority or normal scan.
• “PRI-SCAN 16” or “NORMAL SCAN” appears in the function
display.
• When a signal is detected, scan pauses until the signal disappears or resumes after pausing 5 sec. according to set mode setting. (Channel 16 is still monitored during priority scan.)
• Rotate the [CHANNEL] to check the scanning tag channels, to
change the scanning direction or resume the scan manually.
• “16” blinks and a beep tone sounds when a signal is received on
channel 16 during priority scan.
• “TAG” appears in the function display.
r To cancel the tag channel setting, repeat e.
• “TAG” disappears.
• Clearing all tag channels in the selected channel group
➥ While pushing [H/L], push [5 TAG] for 3 sec. to clear all tag
channels in the channel group.
