USING CHANNEL 16 DISTRESS CALL PROCEDURE 1. MAYDAY MAYDAY MAYDAY. 2. THIS IS ............... (name of vessel). 3. Say your call sign or other description of the vessel (AND 9 digit DSC ID if you have one). 4. LOCATED AT ............... (your position). 5. State the nature of the distress and assistance required. 6. Give any other information which might facilitate the res-

cue. 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, hold down [DISTRESS]

for 3 seconds until you hear 3 short beeps and then one long beep. 2. Wait for an acknowledgment on Channel 70 from a coast station. After the acknowledgement is received, Channel 16 is auto-

3. Hold down [PTT], then transmit the appropriate informa-

matically selected. tion as listed above. Installation:

The installation of this equipment should be made in such a manner as to respect the EC recommended electromagnetic field exposure limits. (1999/519/EC) The maximum RF power available from this device is 25 watts. The antenna should be installed as high as possible for maximum efficiency and the installation height should be at least 1.4 meters above any accessible position. In the case where an antenna cannot be installed at a reasonable height, then the transmitter should neither be continuously operated for long periods if any person is within a distance of 1.4 me-

ters of the antenna, nor operated at all if any person is touch-

ing the antenna. It is recommended that antenna of a maximum gain of 3 dB are used. If higher gain antenna are required then please contact your Icom distributor for revised installation recom-

mendations. Operation:

The exposure to RF electromagnetic field is only applicable when this device is transmitting. This exposure is naturally re-

duced due to the nature of alternating periods of receiving and transmitting. Keep your transmissions to the minimum neces-

sary. ii RADIO OPERATOR WARNING W ARN ING Icom requires the radio operator to meet the FCC and IC Requirements for Radio Fre-

quency 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 and IC Safe Maximum Permissible Expo-

sure (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 verti-

cally 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 al-

lowable MPE level set by FCC and IC. iii FAILURE TO OBSERVE THESE LIMITS MAY ALLOW THOSE WITHIN THE MPE RADIUS TO EXPERIENCE RF RADIATION ABSORPTION WHICH EXCEEDS THE MAXI-

MUM 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. AVERTISSEMENT POUR LES OPRATEURS RADIO LE NON-RESPECT DE CES LIMITES PEUT CAUSER, POUR LES PERSONNES SITUES DANS LE RAYON D'EXPOSITION MAXI-

L'OPRATEUR RADIO EST RESPONSABLE D'ASSURER QUE LES LIMITES D'EXPOSITION MAXIMALE ADMISSIBLE SOIENT RESPECTES EN TOUT TEMPS PENDANT LA TRANSMISSION RADIO. L'OPRATEUR RADIO DOIT S'ASSURER QU'AUCUNE PERSONNE PRSENTE NE SE SITUE L'INTRIEUR DU RAY-

ON D'EXPOSITION MAXIMALE ADMISSIBLE. tablir le rayon d'exposition maximale admissible ON ESTIME QUE LE RAYON D'EXPOSITION MAXIMALE ADMIS-

SIBLE EST D'ENVIRON 3 M, TEL QUE STIPUL DANS LE BUL-

LETIN OET 65 DE LA FCC. CETTE DISTANCE ESTIME TIENT COMPTE D'UN SYSTME INSTALL SUR UN NAVIRE UTILISANT LA PUISSANCE MAXIMALE DE LA RADIO ET DES ANTENNES DONT LE GAIN MAXIMAL EST DE 9dBi. A V E R T I S S E M E N T Icom exige que l'oprateur radio se conforme aux exigences de la FCC et dIC en matire d'exposition aux radiofrquences. Une antenne omnidirectionnelle dont le gain ne dpasse pas 9dBi doit tre fixe une distance minimale de 5 mtres (mesure depuis le point le plus bas de l'antenne) verticalement au-dessus du pont principal et de tout le personnel qui peut s'y trouver. Il s'agit de la distance de scurit minimale prvue pour satisfaire aux exigences de conformit en mat-

ire d'exposition aux RF. Cette distance de 5 mtres est tablie en fonction de l'exposition maximale admissible scuritaire de 3 mtres tablie par la FCC et dIC, laquelle on ajoute la hauteur d'un adulte

(2 mtres); cette distance convient pour tous les navires. Dans le cas des embarcations sans structure convenable, l'antenne doit tre fixe de faon maintenir une distance minimale de 1 mtre verticalement entre cette antenne (mesure depuis son point le plus bas) et la tte de toute personne prsente; toutes les personnes prsentes doivent se tenir l'extrieur d'un rayon d'exposition maxi-

male admissible de 3 mtres. Ne pas mettre l'aide de la radio et de l'antenne lorsque des personnes se trouvent l'intrieur du rayon d'exposition maximale admissible de cette antenne, moins que ces personnes (comme le conducteur ou l'oprateur radio) ne soient protges du champ de l'antenne par un cran mtallique reli la masse. Le rayon d'exposition maximale admissible quivaut la distance minimale que cette personne doit maintenir entre elle et l'axe de l'antenne pour viter une exposition aux RF suprieure au niveau d'exposition maxi-

male admissible fix par la FCC et dIC. iv FCC INFORMATION RECOMMENDATION CLEAN THE TRANSCEIVER AND MICROPHONE THOR-

OUGHLY WITH FRESH WATER after exposure to saltwater, and dry it before operating. Otherwise, the transceiver's keys, switches and controllers may become unusable, due to salt crystallization. NOTE: If the transceivers waterproof protection appears defective, carefully clean it with a soft, damp (fresh water) cloth, then, dry it before operating. The front panel may lose its waterproof protection if the case, jack cap, or connector cover is cracked or broken, or the front panel has been dropped. Contact your Icom distributor or your dealer for advice. This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruc-

tion manual, may cause harmful interference to radio com-

munications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be re-

quired to correct the interference at his own expense. CAUTION: Changes or modifications to this transponder, not expressly approved by Icom Inc., could void your author-

ity to operate this transponder under FCC regulations. NOTE: A WARNING STICKER is supplied with the USA version transceiver.

D Privacy Information overheard, but not intended for you, cannot law-

fully be used in any way. Indecent or profane language is prohibited. D Radio licenses

(1) SHIP STATION LICENSE You may require a current radio station license before using the transceiver. It is unlawful to operate a ship station which is not licensed, but required to be. If required, contact your dealer or the appropriate govern-

ment agency for a Ship-Radiotelephone license application. This government-issued license states the call sign which is your crafts identification for radio purposes. OPERATING RULES 1

(2) OPERATORS 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. If required, the Restricted Radiotelephone Operator Permit must be posted or kept with the operator. If required, 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 regu-

lations 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 regula-

tions. NOTE: Even though the transceiver is capable of opera-

tion on VHF marine channels 1021, 1023, 1081, 1082 and 1083, according to FCC regulations these simplex chan-

nels cannot be lawfully used by the general population in USA waters. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 1 2 PREPARATION MMSI code programming The 9 digit MMSI (Maritime Mobile Service Identity: DSC self ID) code can be programmed at power ON.

Icom is not responsible for the destruction or damage to the Icom transceiver, if the malfunction is because of:

Force majeure, including, but not limited to, fires, earth-

quakes, storms, floods, lightnings, or other natural disas-

ters, disturbances, riots, war, or radioactive contamination. The use of Icom transceiver with any equipment that is not manufactured or approved by Icom. IN CASE OF EMERGENCY INSTALLATION NOTE 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. Say your call sign or other description of the vessel (AND 9 digit DSC ID if you have one). 4. LOCATED AT ............... (your position). 5. State the nature of the distress and assistance required. 6. Give any other information which might facilitate the res-

cue. Or, make 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, hold down [DISTRESS]

3. Hold down [PTT], then transmit the appropriate informa-

matically selected. tion as listed above. Installation:

The installation of this equipment should be made in such a manner as to respect the EC recommended electromagnetic field exposure limits. (1999/519/EC) The maximum RF power available from this device is 25 watts. The antenna should be installed as high as possible for maximum efficiency and the installation height should be at least 1.4 meters above any accessible position. In the case where an antenna cannot be installed at a reasonable height, then the transmitter should neither be continuously operated for long periods if any person is within a distance of 1.4 me-

ters of the antenna, nor operated at all if any person is touch-

ing the antenna. It is recommended that antenna of a maximum gain of 3 dB are used. If higher gain antenna are required then please contact your Icom distributor for revised installation recom-

mendations. Operation:

The exposure to RF electromagnetic field is only applicable when this device is transmitting. This exposure is naturally reduced due to the nature of alternating periods of receiving and transmitting. Keep your transmissions to the minimum necessary.

pan and the United States. ii RADIO OPERATOR WARNING W ARN ING Icom requires the radio operator to meet the FCC Requirements for Radio Frequency Expo-

sure. An omnidirectional antenna with gain not greater than 9 dBi must be mounted a mini-

mum 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 com-

pliance 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 verti-

cally 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 al-

lowable 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 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. AVERTISSEMENT POUR LES OPRATEURS RADIO LE NON-RESPECT DE CES LIMITES PEUT CAUSER, POUR LES PERSONNES SITUES DANS LE RAYON D'EXPOSITION MAXI-

LETIN OET 65 DE LA FCC. CETTE DISTANCE ESTIME TIENT COMPTE D'UN SYSTME INSTALL SUR UN NAVIRE UTILISANT LA PUISSANCE MAXIMALE DE LA RADIO ET DES ANTENNES DONT LE GAIN MAXIMAL EST DE 9dBi. A V E R T I S S E M E N T Icom exige que l'oprateur radio se conforme aux exigences de la FCC en matire d'exposition aux radiofrquences. Une antenne omnidirectionnelle dont le gain ne dpasse pas 9dBi doit tre fixe une distance minimale de 5 mtres (mesure depuis le point le plus bas de l'antenne) verticale-

ment au-dessus du pont principal et de tout le personnel qui peut s'y trouver. Il s'agit de la distance de scurit minimale prvue pour satisfaire aux exigences de conformit en matire d'exposition aux RF. Cette distance de 5 mtres est tablie en fonction de l'exposition maximale admissible scuritaire de 3 mtres tablie par la FCC, laquelle on ajoute la hauteur d'un adulte (2 mtres); cette distance convient pour tous les navires. Dans le cas des embarcations sans structure convenable, l'antenne doit tre fixe de faon maintenir une distance minimale de 1 mtre verticalement entre cette antenne (mesure depuis son point le plus bas) et la tte de toute personne prsente; toutes les personnes prsentes doivent se tenir l'extrieur d'un rayon d'exposition maxi-

male admissible de 3 mtres. Ne pas mettre l'aide de la radio et de l'antenne lorsque des personnes se trouvent l'intrieur du rayon d'exposition maximale admissible de cette antenne, moins que ces personnes (comme le conducteur ou l'oprateur radio) ne soient protges du champ de l'antenne par un cran mtallique reli la masse. Le rayon d'exposition maximale admissible quivaut la distance minimale que cette personne doit maintenir entre elle et l'axe de l'antenne pour viter une exposition aux RF suprieure au niveau d'exposition maxi-

male admissible fix par la FCC. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 iv MISE EN GARDE: Tout changement ou modification, non express-

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 law-

fully be used in any way. Indecent or profane language is prohibited.

(2) OPERATORS 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. If required, the Restricted Radiotelephone Operator Permit must be posted or kept with the operator. If required, 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. D Radio licenses

(1) SHIP STATION LICENSE You may require a current radio station license before using the transceiver. It is unlawful to operate a ship station which is not licensed, but required to be. A current copy of the applicable government rules and regu-

lations 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. If required, contact your dealer or the appropriate govern-

ment agency for a Ship-Radiotelephone license application. This government-issued license states the call sign which is your crafts identification for radio purposes. NOTE: Even though the transceiver is capable of opera-

tion on VHF marine channels 1021, 1023, 1081, 1082 and 1083, according to FCC regulations these simplex chan-

nels cannot be lawfully used by the general population in USA waters. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 11 2 PANEL DESCRIPTION Front panel Speaker q Function display (p. 5) w e r UP AND DOWN/CHANNEL SELECT KEYS [CH]/[CH]

tem is the antenna. Ask your dealer about antennas and the best place to mount them. Mounting bracket For mounting bracket Knob bolts Flat washers (M5) Fuse replacement One fuse is installed in the supplied DC power cable. If the fuse blows or the transceiver stops functioning, track down the source of the problem, repair it, and replace the damaged fuse with a new one of the proper rating. Fuse rating: 10 A Cleaning If the transceiver becomes dusty or dirty, wipe it clean with a soft, dry cloth. DO NOT use harsh solvents such as benzine or alcohol, as they will damage the transceivers sur-

faces. 86 Screws (520 mm) Spring washers (M5) Microphone hanger and screws (316 mm) DC power cable GPS antenna and double-sided adhesive pad*

* Not supplied, or the type is different, depending on the trans-

ceivers versions. Mounting the transceiver D Using the supplied mounting bracket The universal mounting bracket supplied with your transceiv-

er allows overhead or dashboard mounting. q Mount the bracket securely to a surface which is more than 10 mm thick and can support more than 5 kg using the two supplied screws (5 20 mm). w Attach the transceiver to the bracket so that the face of the transceiver is at 90 to your line of sight when operating it. KEEP the transceiver and microphone at least 1 meter away from the vessels magnetic navigation compass. NOTE: Check the installation angle; the function display may not be easy-to-read at some angles. NOTE for the IC-M423G and IC-M424G:

Built-in GPS receiver is located at the right top of the front panel. If the transceiver is covered with any object that interrupts the GPS signals from the satellites, the GPS receiver will not calculate its position. Therefore, when you use the built-in GPS receiver, be sure the transceiver is positioned so the GPS receiver has a clear view to receive signals from satellites. NOTE for the IC-M423GE: Be sure the GPS antenna is positioned where the GPS antenna has a clear view to receive signal from satellites, and fixed using the supplied double-sided adhesive pad.
