[. . . ] INSTRUCTION MANUAL VHF MARINE TRANSCEIVER iM501EURO IN CASE OF EMERGENCY If your vessel requires assistance, contact other vessels and the Coast Guard by sending a distress call on channel 16. Or, transmit your distress call using digital selective calling on channel 70 (the optional DS-100 must be installed). USING CHANNEL 16 DISTRESS CALL PROCEDURE 1. Your call sign or other indication of the vessel (AND 9-digit DSC ID if you have one). Any other information which might facilitate the rescue. USING DIGITAL SELECTIVE CALLING (ch 70) (DS-100 DSC CONTROLLER is required) DISTRESS CALL PROCEDURE 1. [. . . ] · Some channels are for low power only. w r r t 8 BASIC OPERATION 3 I Call channel programming The call channel switch can be programmed to your most often-used channels in each channel group for quick recall. q While pushing [HI/LO], push [DIAL] one or more times to select the desired channel group (International, U. S. A. , Holland, ATIS, DSC) to be programmed. to enter the call channel programming condition. · Channel number starts flashing. INT 25W CALL TAG CALLING I Channel names Memory channels can be tagged with alphanumeric names of up to 10 characters each. q Select the desired memory channel. · Cancel dual watch, tri-watch or scan in advance. w While pushing [HI/LO], push [CALL] to edit memory channel name. · A cursor appears and blinks. INT 25W TAG äLEASURE e Select the desired character by rotating the channel selector or by pushing [Y]/[Z] on the microphone. · Push [SCAN] or [DIAL] for cursor movement. e Rotate the channel selector to select the desired channel. 25W TAG INTL INT CALL DUP r Push [CALL] to input and set the name. r Push [CALL] to program the displayed channel as the call channel. · Push [DIAL] to cancel. · The cursor disappears. t Repeat steps q to r to program another memory channel names, if desired. 9 3 BASIC OPERATION I Optional voice scrambler operation Activating the scrambler The optional voice scrambler provides private communications. In order to receive or send scrambled transmissions you must first activate the scrambler function. w While pushing [HI/LO], push [DIMMER] to toggle an optional scrambler function ON or OFF. · "SC" appears. Programming scrambler codes There are 128 or 32 codes (0 to 127 or 1 to 32) available for programming. In order to understand one another, all transceivers in your group must have the same scramble code. r Push [16] one or more times to select the scrambler code item. · "Scrambler code" appears. e To turn the scrambler function OFF, repeat step w. · "SC" disappears. t Rotate the channel selector to select the desired scrambler code. [Example]: Programming scrambler code 127. 16 + POWER Set mode Beep 16 Set mode Scrambler code Set mode Scrambler code Enter set mode Push one or more times. Select code Set mode Scrambler code item 10 DUAL WATCH/TRI-WATCH I Description Dualwatch monitors channel 16 while you are receiving another channel; tri-watch monitors channel 16 and the call channel while receiving another channel. 4 I Operation q Select the desired operating channel. 15) e Push [DUAL] to start dualwatch or tri-watch. · "DUAL" appears during dualwatch; "TRI" appears during tri-watch. · Tri-watch becomes dualwatch when receiving a signal on the call channel. DUALWATCH/TRI-WATCH SIMULATION Call channel r To cancel dualwatch/tri-watch, push [DUAL] again. [Example]: Operating tri-watch on INT channel 25. INT 25W TAG TRI DUP 16 Tri-watch starts. Dualwatch Tri-watch BUSY INT 25W CALL TAG CALLING 16 BUSY 25W TAG CALLING INT DUP 16 INT 25W TAG TRI DUP 16 Signal is received on call channel. · If a signal is received on channel 16, dualwatch/tri-watch pauses on channel 16 until the signal disappears. · If a signal is received on the call channel during tri-watch, triwatch becomes dualwatch until the signal disappears. · To transmit on the selected channel during dualwatch/tri-watch, push and hold [PTT]. Signal received on channel 16 takes priority. Tri-watch resumes after the signal disappears. 11 5 SCAN OPERATIONS I Scan types Scanning is an efficient way to locate signals quickly over a wide frequency range. Clear the tag channels which inconveniently stop scanning, such as digital communication use. 15) PRIORITY SCAN CH 01 CH 02 NORMAL SCAN CH 01 CH 02 CH 06 CH 16 CH 03 CH 06 CH 03 CH 05 CH 04 CH 05 CH 04 Priority scan searches through all tag channels in sequence while monitoring channel 16. When a signal is detected on channel 16, scan pauses until the signal disappears; when a signal is detected on a channel other than channel 16, scan becomes dualwatch until the signal disappears. 12 Normal scan, like priority scan, searches through all tag channels in sequence. However, unlike priority scan, channel 16 is not checked unless channel 16 is set as a tag channel. SCAN OPERATION 5 I Setting tag channels For more efficient scanning, add desired channels as tag channels or clear tag channels for unwanted channels.

I Connections q e w CAUTION: Transmitting without an antenna may damage the transceiver. r EXTERNAL SPEAKER JACK Connects to an external speaker. 25 for available external speakers. q DC POWER CONNECTOR Connects the supplied DC power cable from this connector to an external 12 V DC power source. MICROPHONE HANGER Rest the supplied microphone on the hanger when not in use. CAUTION: After connecting the DC power cable and external speaker jack, cover the connector and jack as shown below to avoid water seeping into the transceiver. 18 CONNECTIONS AND MAINTENANCE 7 I Mounting the transceiver Using the supplied mounting bracket The universal mounting bracket supplied with your transceiver allows overhead or dashboard mounting. · Mount the transceiver securely with the 2 supplied screws (M5 × 20) to a surface which is more than 10 mm thick and can support more than 5 kg.
