[. . . ] INSTRUCTION MANUAL VHF MARINE TRANSCEIVER iM88 This device complies with Part 15 of the FCC Rules. Operation is subject to the follow two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. SAFETY TRAINING INFORMATION Your Icom radio generates RF electromagnetic energy during transmit mode. This radio is designed for and classified as "Occupational Use Only", meaning it must be used only during the course of employment by individuals aware of the hazards, and the ways to minimize such hazards. This radio is NOT intended for use by the "General Population" in an uncontrolled environment. [. . . ] q Push [CH/WX·U/I/C/L] to select a regular channel. · If a weather channel appears, push [CH/WX·U/I/C/L] again. 4 D Weather channels (Available for USA version only) There are 10 weather channels. They are used for monitoring weather channels from the NOAA (National Oceanographic and Atmospheric Administration) broadcasts. q Push [CH/WX·U/I/C/L] to select the weather channel group. e Push [CH/WX·U/I/C/L] to return to the condition before selecting the weather channel group. U/I/C/L w Push [Y]/[Z] to select a channel. · "DUP" appears for duplex channels. e To change the channel group, push [CH/WX·U/I/C/L] for 1 sec. · U. S. A. , International and Canadian channels can be selected in sequence. 16 for details. Push Push for 1 sec. U/I/C/L U/I/C/L For your convenience: The IC-M88 can detect a weather alert tone on the selected weather channel while receiving in another channel or during scanning. channels U/I/C/L International channels Canadian channels 9 4 BASIC OPERATION IMPORTANT: To maximize the readability of your transmitted signal, pause a few sec. after pushing [PTT], hold the microphone 5 to 10 cm (2 to 4 inches) from your mouth and speak at a normal voice level. NOTE: The transceiver has a power save function to conserve the battery power and it cannot be turned OFF. The power save function activates automatically when no signal is received for 5 sec. For U. S. A version: To prevent accidental prolonged transmission, etc. , the IC-M88 has a time-out timer function. y Push and hold to transmit u Release to receive w Opening the squelch q Power ON e Set volume I Receiving and transmitting CAUTION: Transmitting without an antenna may damage the transceiver. q Rotate [VOL] clockwise to turn power ON. After pushing the [SQL] for 1 sec. , the squelch function is cut off until [SQL] is released. r Push [Y]/[Z] to select the desired channel. - When receiving a signal, " " appears and audio is emitted from the speaker. - Further adjustment of [VOL] may be necessary at this point. t Push [H/L·LOCK] to select the output power if necessary. - "LOW" appears when low power is selected; "MID" appears when middle power is selected; no indication when high power is selected. - Choose low power to conserve battery power, choose high power for longer distance communications. - Some channels are for low power only. y Push and hold [PTT] to transmit, then speak into the microphone. - "TX" appears. - Channel 70 cannot be used for transmission (for GMDSS use). u Release [PTT] to receive. r Set channel t Set output power 10 BASIC OPERATION 4 I Adjusting the squelch level The IC-M88 has a squelch even though there is no control knob for it. In order to receive signals properly, as well as for the scan to function effectively, the squelch must be adjusted to the proper level. q Push [SQL], then adjust the squelch level with [Y]/[Z]. - "SL" indicator appears. - There are 11 squelch levels to choose from: OP is completely open; 10 is the tight squelch level. - When no key is pushed for 5 sec. , the transceiver returns to normal condition. I Voice scrambler operation (Available for I/S version only) D 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. [. . . ] Turn the power ON to check if the internal temperature has returned to normal. · The connected battery pack's voltage is · Verify the battery voltage is correct. · Have the transceiver checked at your local distributor or dealer to see whether the transceiver works properly or not. -- -- 28 VHF MARINE CHANNEL LIST Channel number Frequency (MHz) USA INT CAN Transmit Receive 01 01A 02 03 03A 04 05 05A 06 07A 08 09 10 11 12 13* 14 15* 16 17* 18A 19 08 09 10 11 12 13 14 15* 16 17 18 06 07 08 09 10 11 12 13* 14 15* 16 17* 06 02 03 01 156. 050 160. 650 156. 050 156. 050 156. 100 160. 700 156. 150 160. 750 156. 150 156. 150 156. 200 160. 800 04A 156. 200 156. 200 156. 250 160. 850 05A 156. 250 156. 250 156. 300 156. 300 156. 350 160. 950 07A 156. 350 156. 350 156. 400 156. 400 156. 450 156. 450 156. 500 156. 500 156. 550 156. 550 156. 600 156. 600 156. 650 156. 650 156. 700 156. 700 156. 750 156. 750 156. 800 156. 800 156. 850 156. 850 156. 900 161. 500 18A 156. 900 156. 900 156. 950 161. 550 65A 64A 65 65A 63A 64 64 63 61A 62 23A 24 25 26 27 28 24 25 26 27 28 60 61 24 25 26 27 28 60 22A 23 21A 22 23 Channel number Frequency (MHz) USA INT CAN Transmit Receive 19A 20 20A 21 21 20 19A 156. 950 156. 950 20* 157. 000 161. 600 157. 000 157. 000 157. 050 161. 650 157. 100 161. 700 22A 157. 100 157. 100 157. 150 161. 750 157. 150 157. 150 157. 200 161. 800 157. 250 161. 850 157. 300 161. 900 157. 350 161. 950 157. 400 162. 000 156. 025 160. 625 156. 075 160. 675 61A 156. 075 156. 075 156. 125 160. 725 62A 156. 125 156. 125 156. 175 160. 775 156. 175 156. 175 156. 225 160. 825 83A 84 84A 84 156. 275 160. 875 65A 156. 275 156. 275 64A 156. 225 156. 225 82A 83 81A 82 83 84 80A 81 79A 80 78A 79 21A 157. 050 157. 050 Channel number Frequency (MHz) USA INT CAN Transmit Receive 66 66A 67* 68 69 70 71 72 73 74 77* 67 68 69 70 71 72 73 74 77 78 67 68 69 70 71 72 73 74 77* 156. 325 160. 925 156. 375 156. 375 156. 425 156. 425 156. 475 156. 475 Rx only 156. 525 156. 575 156. 575 156. 625 156. 625 156. 675 156. 675 156. 725 156. 725 156. 875 156. 875 156. 925 161. 525 78A 156. 925 156. 925 156. 975 161. 575 79A 156. 975 156. 975 157. 025 161. 625 80A 157. 025 157. 025 157. 075 161. 675 81A 157. 075 157. 075 157. 125 161. 725 82A 157. 125 157. 125 157. 175 161. 775 157. 225 161. 825 157. 225 157. 225 83A 157. 175 157. 175 WX channel 1 2 3 4 5 6 7 8 9 10 66A 66A* 156. 325 156. 325 85 85A 86 86A 87 87A 88 88A 21b 25b 28b 83b 88 88 87 87 86 86 85 85 12 Channel number Frequency (MHz) USA INT CAN Transmit Receive 157. 275 161. 875 157. 275 157. 275 157. 325 161. 925 157. 325 157. 325 157. 375 161. 975 157. 375 157. 375 157. 425 162. 025 157. 425 157. 425 Rx only 161. 650 Rx only 161. 850 Rx only 162. 000 Rx only 161. 775 Frequency (MHz) Transmit RX only RX only RX only RX only RX only RX only RX only RX only RX only RX only Receive 162. 550 162. 400 162. 475 162. 425 162. 450 162. 500 162. 525 161. 650 161. 775 163. 275 *Low power only.
