User manual ICOM IC-M100

[. . . ] Exposing the inside of the transceiver to water will result in serious damage to the transceiver. AVOID the use of chemical agents such as benzine or alcohol when cleaning, as they may damage the transceiver surfaces. BE CAREFUL!The transceiver rear panel will become hot when operating continuously for long periods. After exposure to saltwater, clean the transceiver thoroughly with fresh water to avoid corrosion. NEVER allow children to touch the transceiver. NEVER charge battery packs except in the methods dei scribed in this manual.

[. . . ] Used for monitoring weather channels from the NOAA (National Oceanographic and Atmospheric Administration) broadcasts. The IC-M10000 can detect a weather alert tone on the selected weather channel while receiving the channel, during standby on a regular channel or while scanning. See the "SET mode items" on p. · Push [CH/WX] once or twice to select weather channels. 2 s Adjusting the squelch level The IC-M10000 has a squelch even though there is no control knob for it. In order to receive signals properly, as well as for scan to function, the squelch must be adjusted to a suitable level. Level 4: Max. squelch level 1 While pushing [SQL], rotate the channel selector. - The first click of the channel selector indicates the current squelch level. - There are 5 squelch levels to choose from: 0 is completely open; 4 is the maximum squelch level. s Lock function This function electronically locks all keys and switches to prevent accidental frequency changes and function access. · Push [H/L·LOCK] for 1 sec. to turn the lock function ON and OFF. - Only [PTT], [H/L] and [SQL] are functional. Appears when the lock function is in use. USA 2 Release [SQL] when the desired squelch level is indicated in the function display. NOTE: The squelch level 1 is designed for receiving weak signals so that the squelch delays to close. to start tri-watch. - "DUAL" flashes during dualwatch; "TRI" flashes during tri-watch. - Beep tone sounds when a signal is received on channel 16. - Tri-watch becomes dualwatch when receiving a signal on the call channel. Call channel 3 To cancel dualwatch/tri-watch, push [DW·TRI] again. [Example]: Operating tri-watch on INT channel 07. Push for 1 sec. TRI DW TAG TRI DUP INT Tri-watch starts. BUSY CALL Dualwatch Tri-watch TAG TRI INT 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]. · If no signal is received, the transceiver enters the power saving condition for 0. 5 sec. after checking the operating channel every cycle. BUSY TAG TRI DUP INT Signal received on channel 16 takes priority. Tri-watch resumes after the signal disappears. TAG TRI DUP INT 10 4 SCAN OPERATION s Scan types Scanning is an efficient way to locate signals quickly over a wide frequency range. The transceiver has priority scan and normal scan. [. . . ] · Check the connection to the transceiver. · Set squelch to the threshold point. · Set [OFF/VOL] to a suitable level. · Push [H/L] to select high power. [. . . ]
