[. . . ] Push [DUAL·TRI] momentarily for dualwatch. DUAL I Receiving Rotate [PWR/VOL] to turn power ON. Rotate [SQUELCH] clockwise until the audio noise disappears. Select the desired channel. This may distort the transmit signal. Release the PTT switch to receive. IMPORTANT: In order to maximize the readability of your transmitted signal, pause for a moment after pushing [PTT], hold the microphone 15­20 cm from your mouth, then speak into the microphone at an even, normal voice level. MOMENTARY HIGH POWER On U. S. A. channels 13, 15 and 67, transmission using high power is momentarily possible. To use high power, push and hold [HI/LO] while transmitting. TIME-OUT TIMER (U. S. A. version only) The transceiver has a time-out timer function to prevent continuous, long transmissions. 9 3 BASIC OPERATION D Scan operation Select the desired channel group (USA, CAN, INT) or WX channels with [CH/WX·U/I/C]. · When the weather alert function is in use, select the desired WX channel in the display, then perform the above operation. I Scan function The transceiver has a high speed scan function for standing by on utility signals. Two scan types are available: normal scan (scans all tag channels in sequence) and priority scan (checks channel 16 while scanning). 19). Push [SCAN] to start scanning. · "SCAN" appears and flashes in the function display. · "16" appears during priority scan. To stop the scan, push [SCAN] again. · "SCAN" disappears. D Setting tag channels You can specify channels as tag channels for efficient scanning. Tag channels can be set for each channel group (USA, CAN, INT) independently. NOTE: When a GPS receiver (NMEA 0183) is connected, your vessel's position is automatically transmitted with the distress call. NOTE: Acknowledgement of a DSC distress alert is normally made by coast stations only. 13 TX INT The transceiver remains on channel 70 until an acknowledgement is received. · When no acknowledgement is received, the distress call is repeated until an acknowledgement is received. · Calls to you other than distress acknowledgement cannot be received. 4 DIGITAL SELECTIVE CALLING I All ships call transmission Large ships use channel 70 as their "listening channel. " When you want to announce a message to these ships, use the "all ships call" function. Push and hold [PTT] again to send an announcement to all ships. NOTE: Channel busy When channel 70 is busy, the all ships call is not transmitted. The transceiver waits until the channel is clear, then transmits the call automatically. BUSY Select a simplex channel for the traffic channel (for voice communication after sending the all ships call). USA LOW USA · Some `A' channels (eg. channel 88A) cannot be used. This display appears while the call is in standby. Rotate [SQUELCH] clockwise until the audio noise disappears. While pushing [9·ALL/IND] rotate the channel selector to select "ALL" as at right. Push and hold [9 ·ALL/IND] until you hear 4 short beeps change to one long beep. · The display changes as at right. LOW USA LOW USA NOTE: Error indication When a transmission inhibited LOW USA channel (e. g. ch 70) is selected for the traffic channel, the display at right appears. This display may also appear if [9·ALL/IND] is accidentally released early while being pushed and held in step . Push [PTT] momentarily to transmit the all ships call. · After transmission, the channel set in step above is selected. TX LOW USA USA 14 DIGITAL SELECTIVE CALLING 4 I Individual call transmission The individual call function allows you to transmit a DSC signal to a specific party only. Standby on channel 70 until an acknowledgement is received. Set the ID code for the individual you wish to call in advance. · This code is input into the address item in SET mode. 19) When the acknowledgement is received, the display changes as at right. · Beeps sound.

Ask your Dealer about antennas and the best places to mount them. I Cleaning If the transceiver becomes dusty or dirty, wipe it clean with a dry, soft cloth. AVOID the use of solvents such as benzene or alcohol, as they may damage transceiver surfaces. I Fuse replacement Two fuses are installed in the supplied DC power cable. If a fuse blows or the transceiver stops functioning, track down the source of the problem, if possible, and replace the damaged fuse with a new, rated one. Fuse rating: 10 A I Optional unit installations In order to add the DSC or voice scrambler functions to the IC-M9, the following optional units must be installed. [. . . ]
