IN CASE OF EMERGENCY
If your vessel requires assistance, contact other vessels and the Coast Guard by sending a distress call on Channel 16.
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.
NOTE
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 as in the diagram below. Make sure the chosen location is clean and dry before applying the sticker.

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 AR N IN G 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.
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 EXPO-
SURE 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) RA-
DIUS 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 MAXI-
MUM GAIN OF 9dBi ARE USED FOR A SHIP MOUNTED
SYSTEM.

PRECAUTION
R
WARNING! NEVER
connect the transceiver to an AC outlet. This may pose a fire hazard or result in an electric shock.
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 rear panel will become hot when operating continuously for long periods.
Place the transceiver in a secure place to avoid inadvertent use by children.
BE CAREFUL!
The transceiver and optional HM-127*employ waterproof construction, which corresponds to JIS 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.
*IC-M402A only

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.
• 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.
OPERATING RULES
1
(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 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.

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. 31)
PRIORITY SCAN
CH 01 CH 02
Set the tag channels (scanned channel) before scanning.
Clear the tag channels which inconveniently stop scanning, such as those for digital communication use.
Choose Priority or Normal scan in Set mode. (p. 31)
NORMAL SCAN
CH 01 CH 02
CH 06 CH 16 CH 03 CH 06 CH 03
CH 05 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.
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.

Channels are not tagged will be skipped during scanning. Tag channels can be assigned to each channel group (USA, INT,
CAN) independently.
q Select the desired channel group (USA, INT, CAN) by pushing both [ Y ] and [ Z ] .
w Select the desired channel to set as a tag channel.
e Push [SCAN• TAG ] for 1 sec. to be set the displayed channel as a tag channel.
• “ ” appears in the display.
r To cancel the tag channel setting, push [SCAN• TAG ] for

• “ ” disappears.
✔
Clearing (or setting) all tagged channels
While pushing [HI/LO] on the microphone, push [SCAN• TAG ] for 3 sec. (until a long beep changes to 2 short beeps) to clear all tag channels in the channel group.
• Repeat above procedure to set all tag channels.
[Example] : Starting a normal scan.
