iiIN CASE OF EMERGENCYIf your vessel requires assistance, contact other vessels andthe Coast Guard by sending a distress call on Channel 16.Or, transmit your distress call using digital selective calling onChannel 70.NOTEA WARNING STICKER is supplied with the transceiver.To comply with FCC regulations, this sticker must be affixed insuch a location as to be readily seen from the operating con-trols of the radio. Make sure the chosen location is clean anddry before applying the sticker.USING DIGITAL SELECTIVE CALLING (Ch 70)DISTRESS CALL PROCEDURE1. While lifting up the key cover, push and hold[DISTRESS] for 5 sec. until you hear 5 short beepschange 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 appropriateinformation as listed above.USING CHANNEL 16DISTRESS CALL PROCEDURE1. “MAYDAY MAYDAY MAYDAY.”2. “THIS IS ...............” (name of vessel)3.

iiiNew2001RADIO OPERATOR WARNINGIcom requires the radio operator to meet theFCC Requirements for Radio Frequency Expo-sure. An omnidirectional antenna with gain notgreater than 9 dBi must be mounted a minimumof 5 meters (measured from the lowest point ofthe antenna) vertically above the main deck andall possible personnel. This is the minimum safe separationdistance estimated to meet all RF exposure compliance re-quirements. This 5 meter distance is based on the FCC SafeMaximum Permissible Exposure (MPE) distance of 3 metersadded to the height of an adult (2 meters) and is appropriatefor all vessels.For watercraft without suitable structures, the antenna mustbe mounted so as to maintain a minimum of 1 meter verticallybetween the antenna, (measured from the lowest point of theantenna), to the heads of all persons AND all persons muststay outside of the 3 meter MPE radius.Do not transmit with radio and antenna when persons arewithin the MPE radius of the antenna, unless such persons(such as driver or radio operator) are shielded from antennafield by a grounded metallic barrier. The MPE Radius is theminimum distance from the antenna axis that person shouldmaintain in order to avoid RF exposure higher than the allow-able MPE level set by FCC.WARNINGFAILURE TO OBSERVE THESE LIMITS MAY ALLOWTHOSE WITHIN THE MPE RADIUS TO EXPERIENCE RFRADIATION ABSORPTION WHICH EXCEEDS THE FCCMAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMIT.IT IS THE RESPONSIBILITY OF THE RADIO OPERATORTO ENSURE THAT THE MAXIMUM PERMISSIBLE EXPO-SURE LIMITS ARE OBSERVED AT ALL TIMES DURINGRADIO TRANSMISSION. THE RADIO OPERATOR IS TOENSURE THAT NO BYSTANDERS COME WITHIN THERADIUS OF THE MAXIMUM PERMISSIBLE EXPOSURELIMITS.Determining MPE RadiusTHE MAXIMUM PERMISSIBLE EXPOSURE (MPE) RA-DIUS HAS BEEN ESTIMATED TO BE A RADIUS OFABOUT 3M PER OET BULLETIN 65 OF THE FCC.THIS ESTIMATE IS MADE ASSUMING THE MAXIMUMPOWER OF THE RADIO AND ANTENNAS WITH A MAXI-MUM GAIN OF 9dBi ARE USED FOR A SHIP MOUNTEDSYSTEM.!IC-M422_FCC.qxd 05.1.14 11:30 AM Page iii (1,1)

vNew2001PRECAUTIONSRWARNING! NEVER connect the transceiver to an ACoutlet. This may pose a fire hazard or result in an electricshock.CAUTION: Changes or modifications to this device, not ex-pressly approved by Icom Inc., could void your authority tooperate this device under FCC regulations.NEVER connect the transceiver to a power source of morethan 16 V DC or use reverse polarity. This will ruin the trans-ceiver.NEVER cut the DC power cable between the DC plug andfuse holder. If an incorrect connection is made after cutting,the transceiver may be damaged.NEVER place the transceiver where normal operation of thevessel may be hindered or where it could cause bodily injury.KEEP the transceiver at least 3.3 ft (1 m) away from theship’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, inareas 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 transceiversurfaces.BE CAREFUL! The transceiver rear panel will becomehot when operating continuously for long periods.Place the transceiver in a secure place to avoid inadvertentuse by children.BE CAREFUL! The transceiver and optional HM-157COMMANDMIC II™ employ waterproof construction, which cor-responds to IPX waterproof specification, Grade 7(1 m/30 min.). However, once the transceiver or microphonehas been dropped, waterproofing cannot be guaranteed dueto the fact that the case may be cracked, or the waterproofseal damaged, etc.!IC-M422_FCC.qxd 05.1.14 11:30 AM Page v (1,1)
11OPERATING RULESDDPRIORITIES• Read all rules and regulations pertaining to priorities andkeep an up-to-date copy handy. Safety and distress callstake priority over all others.• You must monitor Channel 16 when you are not operatingon another channel.• False or fraudulent distress signals are prohibited and pun-ishable by law.DDPRIVACY• Information overheard but not intended for you cannot law-fully be used in any way.• Indecent or profane language is prohibited.DDRADIO LICENSES(1) SHIP STATION LICENSEYou must have a current radio station license before using thetransceiver. It is unlawful to operate a ship station which is notlicensed.Inquire through your dealer or the appropriate governmentagency for a Ship-Radiotelephone license application. Thisgovernment-issued license states the call sign which is yourcraft’s identification for radio purposes.(2) OPERATOR’S LICENSEA Restricted Radiotelephone Operator Permit is the licensemost often held by small vessel radio operators when a radiois not required for safety purposes.The Restricted Radiotelephone Operator Permit must beposted or kept with the operator. Only a licensed radio opera-tor may operate a transceiver.However, non-licensed individuals may talk over a transceiverif a licensed operator starts, supervises, ends the call andmakes the necessary log entries.Keep a copy of the current government rules and regulationshandy.Radio license for boaters (U.S.A. only)The Telecommunications Act of 1996 permits recreationalboaters to have and use a VHF marine radio, EPIRB, andmarine radar without having an FCC ship station license.Boaters traveling on international voyages, having an HFsingle sideband radiotelephone or marine satellite termi-nal, or required to carry a marine radio under any otherregulation must still carry an FCC ship station license.
