INSTRUCTION MANUALiM402VHF MARINE TRANSCEIVERThis device complies with Part 15 of the FCC rules. Operation is sub-ject to the following two conditions: (1) This device may not causeharmful interference, and (2) this device must accept any interferencereceived, including interference that may cause undesired operation.
iREAD ALL INSTRUCTIONS carefully and completelybefore using the transceiver.SAVE THIS INSTRUCTION MANUAL —This in-struction manual contains important operating instructionsfor the IC-M402.The installation of this equipment shouldbe made in such a manner as to respectthe EC recommended electromagneticfield exposure limits (1999/519/EC).The maximum RF power available from this device is 25watts. The antenna should be installed as high as possiblefor maximum efficiency and that this installation heightshould be at least 6 meters above ground (or accessible)level. In the case where an antenna cannot be installed ata reasonable height, then the transmitter should neitherbe continuously operated for long periods if any person iswithin 6 meters of the antenna, nor operated at all if anyperson is touching the antenna. If the antenna cannot beinstalled at 6 meters or graterI, we recommend touse theone watt setting to minimize RF exposure.In all cases any possible risk depends on the transmitterbeing activated for long periods. (actual recommendationlimits are specified as an average of 6 minutes) Normallythe transmitter is not active for long periods of time. Someradio licenses will require that a timer circuit automaticallycuts the transmitter after 1–2 minutes etc.CAUTIONIMPORTANTNOTE FOR RF SAFETY
IN CASE OF EMERGENCYiiIf 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.USING DIGITAL SELECTIVE CALLING (Ch 70)DISTRESS CALL PROCEDURE1.

Wait for an acknowledgment from a coaststation.•Channel 16 is automatically selected.3. Push and hold [PTT], then transmit theappropriate information as at left.USING CHANNEL 16DISTRESS CALL PROCEDURE1. “MAYDAY MAYDAY MAYDAY.”2. “THIS IS ...............” (name of vessel)3. Your call sign or other indication of the vessel(AND 9-digit DSC ID if you have one).4. “LOCATED AT ...............” (your position)5.

ivRWARNING! 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 thevehicle 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-127 em-ploy waterproof construction, which corresponds to JIS wa-terproof specification, grade 7 (1 m/30 min.). However, oncethe transceiver or microphone has been dropped, water-proofing cannot be guaranteed due to the fact that the casemay be cracked, or the waterproof seal damaged, etc.CAUTIONS
11OPERATING RULES◊PRIORITIES•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 operating onanother channel.•False or fraudulent distress signals are prohibited and pun-ishable by law.◊PRIVACY•Information overheard but not intended for you cannot law-fully be used in any way.•Indecent or profane language is prohibited.◊RADIO 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 travelling on international voyages, having an HFsingle sideband radiotelephone or marine satellite terminal,or required to carry a marine radio under any other regula-tion must still carry an FCC ship station license. For furtherinformation, see the FCC Ship Radio Stations Fact Sheet.

9■Scan typesScanning is an efficient way to locate signals quickly over awide frequency range. The transceiver has priority scan andnormal scan.When the weather alert function is in use, the selectedweather channel is checked while scanning. (p. 20)Set the tag channels (scanned channel) before scanning.Clear the tag channels which inconveniently stop scanning,such as digital communication use.Choose priority or normal scan in set mode. (p. 20)NORMAL SCANNormal scan, like priority scan, searches through all tagchannels in sequence. However, unlike priority scan, Chan-nel 16 is not checked unless Channel 16 is set as a tagchannel.CH 01 CH 02CH 06CH 05 CH 04CH 035SCAN OPERATIONSPRIORITY SCANPriority scan searches through all tag channels in se-quence while monitoring Channel 16. When a signal is de-tected on Channel 16, scan pauses until the signal disap-pears; when a signal is detected on a channel other thanChannel 16, scan becomes dualwatch until the signal dis-appears.CH 06CH 01CH 16CH 02CH 05 CH 04CH 03
