No riskof personal injury, fire or electric shock.IC-M45A Manual 99.3.29 2:45 PM Page ii
iiiCAUTIONSRWARNING! NEVER connect the transceiver to anAC outlet. This may pose a fire hazard or result in an electricshock.RWARNING HIGH VOLTAGE! NEVER touchthe antenna or an internal antenna connector during trans-mission. This may result in an electric shock or a burn.NEVER connect the transceiver to a power source of morethan 16 V DC.This connection will ruin the transceiver.AVOID using or placing the transceiver in direct sunlight orin areas with temperatures below –20°C (–4°F) or above+60°C (+140°F).DO NOT operate the transceiver without running the ves-sel’s engine. When your vessel’s engine is OFF and the trans-ceiver is transmitting, the vessel’s battery will soon becomeexhausted.KEEP the transceiver out of the reach of children.KEEP the antenna cable and DC power cable as far awayas possible from electrical pumps, generators and other elec-tronic instruments to prevent instrument malfunctions.KEEP the transceiver and microphone at least 1 meteraway from your vessel’s magnetic navigation compass.IN CASE OF EMERGENCYIf your vessel requires assistance, contact other vessels andthe Coast Guard by sending a distress call on channel 16.❍USING CHANNEL 16DISTRESS CALL PROCEDURE1. “MAYDAY MAYDAY MAYDAY.”2. “THIS IS ...........................” (name of vessel)3.

11OPERATING RULESDPriorities• 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 calls are prohibited under law.DPrivacy• Information overheard but not intended for you cannot law-fully be used in any way.• Indecent or profane language is prohibited.DRadio licensesSHIP STATION LICENSEWhen your craft is equipped with a VHF FM transceiver, youmust 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. This license in-cludes the call sign which is your craft’s identification for radiopurposes.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 near the transceiver or be kept with the operator. Onlya licensed radio operator 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.A current copy of the applicable government rules and regu-lations is only required to be on hand for vessels in which aradio telephone is compulsory. However, even if you are notrequired to have these on hand it is your responsibility to bethoroughly acquainted with all pertinent rules and regulations.NOTE: Even though the IC-M45A is capable of operationon VHF marine channels 3, 21, 23, 61, 64, 81, 82 and 83,according to FCC regulations these channels cannot belawfully used by the general public in USA waters.IC-M45A Manual 99.3.29 2:45 PM Page 1

This function is acti-vated when a weather channel is selected or during any scan.See “SET mode items” on p. 12.PushWXCH WXIC-M45A Manual 99.3.29 2:45 PM Page 6
73BASIC OPERATION■Receiving➀Rotate [PWR/VOL] to turn power ON.➁Rotate [SQUELCH] fully counterclockwise.➂Adjust [PWR/VOL] to a suitable listening level.➃Rotate [SQUELCH] clockwise until the audio noise disap-pears.➄Select a channel. See pgs. 5–6 for details.• When a signal is received:➧The squelch opens.➧Audio is emitted from the speaker.➧“BUSY” appears in the function display.➅When an interrupting signal is received, rotate [SQUELCH]deeply clockwise.DDual/tri-watch functionsThese functions allow you to conveniently check the distresschannel (ch 16) or, both the distress and leisure call channel(ch 9; programmable) while receiving another channel. Whenreceiving a signal on one of these channels, the transceiverstops on the channel until the signal disappears.Depending on your preference, select dual watch or tri-watchin advance in SET mode (p. 12). Dual watch is the default set-ting.When dual watch is selected in SET mode:➥Push [CH/WX • DUAL] for 1 sec. to start dual watch.When tri-watch is selected in SET mode:➥Push [CH/WX • DUAL] for 1 sec. to start tri-watch.➥Push any switch to cancel dual/tri-watch and return to nor-mal operation.USADUALUSADUALBUSYChecking channel 16 every 2 sec.

83BASIC OPERATION■TransmittingBefore transmitting, read the call procedures at right.➀Select an operating channel. See pgs. 5–6 for details.➁Push [H/L] to select a transmit output power.• “LOW” appears when low output power is selected.• High power cannot be selected on some channels. Refer to thechannel list on p. 18.➂Push and hold the [PTT] switch to transmit.•“$” appears.➃Speak into the microphone at your normal voice level.• Do not hold the microphone too closely to your mouth or speak toloudly. This may distort the signal.➄Release the [PTT] switch to receive.vIMPORTANT: In order to maximize the readability ofyour transmitted signal, pause for a moment after push-ing [PTT], hold the microphone 15–20 cm from yourmouth, then speak into the microphone at an even, nor-mal voice level.MOMENTARY HIGH POWEROn USA channels 13, 15 and 67, transmission using highpower is momentarily possible. To use high power, pushand hold [H/L] while transmitting.TIME-OUT TIMER (USA version only)The transceiver has a time-out timer function to preventcontinuous, long transmissions. Transmit is automaticallyinhibited after 5 min. of continuous transmission.CALL PROCEDURESYou must identify yourself when you transmit and you mustrespect time limits.1) Give your call sign each time you call another vessel or acoast station. If you have no call sign, identify the stationby giving the vessel name and the name of the license.2) Give your call sign at the end of each transmission thatlasts more than 3 minutes.3) You must pause and give your call sign at least onceevery 15 minutes during long ship-to-shore calls.4) Keep your calls short (less than 3 minutes). Wait 2 min-utes before repeating a call.5) Unnecessary transmissions are not allowed.IC-M45A Manual 99.3.29 2:45 PM Page 8
93BASIC OPERATION■Scan functionThe transceiver has a high speed scan function for standingby on utility signals. The scan speed is 8 channel/sec. (exceptwhen the weather alert function is in use).Two scan types are available:normal scan (scans all tagchannels in sequence) and priority scan (checks channel 16while scanning). These scans can be selected in SET mode(p. 12).DSetting tag channelsYou can specify channels as tag channels for efficient scan-ning. Tag channels can be set for each channel group (USA,CAN, INT) independently.➥Select the desired channel, then push [SCAN • TAG] for 1sec. to toggle the tag setting.✔Clearing all tag channelsWhile pushing [H/L], push [SCAN • TAG] for 3 sec. until thelong beep becomes 2 short beeps.• All tag channels in the selected channel group are released.USATAGAppears when the channel isspecified as a tag channel.DScan operation➀Select the desired channel group (USA, CAN, INT or WX)channels with [CH/WX] + [H/L] (or [CH/WX] only forweather channels).• When the weather alert function is in use, select the desired WXchannel in the display, then perform the above step.➁Push [SCAN] to start scanning.• “SCAN” appears and flashes in the function display.• “16” appears during priority scan.➂To stop the scan, push [SCAN] again.• “SCAN” disappears.✔Scan resume timerWhen a signal is detected, scan pauses until the signal dis-appears or resumes after pausing 5 sec., according to theSET mode setting. (p. 12)✔Confirming tag channelsWhile operating scan, push [UP] or [DN].• Only tag channels are selected.• Stop pushing [UP] or [DN] to resume scan.✔Weather alert functionWhen this function is turned ON (p. 12), the selected weatherchannel is checked during scan.
