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 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.

WARNING

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

outlet. This may pose a fire hazard or result in an electric shock.

CAUTION: Changes or modiﬁcations to this device, not ex-

pressly 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 at the

back of the transceiver 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 temper-

atures 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 al-

cohol when cleaning, as they may damage the transceiver surfaces. If the transceiver becomes dusty or dirty, wipe it clean with a soft, dry cloth.

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 the optional HM-162

COMMANDMIC III

™/HM-157

COMMANDMIC II

™ employ waterproof construction, which corresponds to IPX8 of the international standard IEC 60529 (2001). 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

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.

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.

(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.

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 scrambler unit is necessary. See pgs. 57, 62 for setting the scrambler unit. Ask your dealer for details.

The scrambler function automatically turns OFF when Channel 16 or 70 is selected.

q Rotate [DIAL] to select an operating channel other than

Channel 16 and 70.

w While pushing and holding [H/L], push [LO/DX•IC•SCRM]

to turn the optional scrambler function ON.

•“

” appears.

e To turn the scrambler function OFF, repeat step w.

•“

Programming scrambler codes

There are 32 codes (1 to 32) or 128 codes (0 to 127)* available for programming when an optional scrambler unit 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.

*Depends on the installed scrambler unit.

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 (last used) weather channel is also checked while scanning. (p. 56)

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.)

Choose Priority or Normal scan in Set mode. (p. 55)

PRIORITY SCAN

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

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

For more efﬁcient scanning, add the desired channels as TAG channels or clear the TAG for unwanted channels. Channels that are not tagged will be skipped during scanning. TAG channels can be assigned to each channel group (USA, INT, CAN) independently.

q While pushing and holding [H/L], push [CH/WX•DUAL•U/I/C]

to select the desired channel group (USA, INT or CAN.)

w Select the desired channel to be set as a TAG channel. e Push [SCAN•TAG] for 1 sec. to set the displayed channel

as a TAG channel.

•“

TTAAGG

” appears in the display.

r To cancel the TAG channel setting, repeat step e.

•“

TTAAGG

” disappears.

✔ Clearing (or setting) all tagged channels

While pushing and holding [H/L], push [SCAN•TAG] for 3 sec. (until a long beep changes to 2 short beeps) to clear all TAG channels setting in the channel group.

• Repeat above procedure to set all TAG channels.

■ Starting a scan

Set scan type (Priority or Normal scan) and scan resume timer in advance, using Set mode. (p. 55)

q While pushing and holding [H/L], push [CH/WX•DUAL•

U/I/C] to select the desired channel group (USA, INT,

CAN) if desired.

w Set TAG channels as described at left. e Make sure the squelch is closed to start a scan. r Push [SCAN•TAG] to start Priority or Normal scan.
