User manual ICOM IC-21

[. . . ] NEVER operate the transceiver while driving a vehicle. Safe driving requires your full attention-- anything less may result in an accident. NEVER connect the transceiver to a power source of more than 16 V DC. This connection will ruin the transceiver. EXPLICIT DEFINITIONS The explicit definitions below apply to this instruction manual. [. . . ] 18) · Pushing and holding [Y] or [Z] changes the frequency continuously. Rotate the selected band's tuning dial to set the desired frequency. · Selectable step increment is the same as the preset tuning step. 18) · Use the selected band's [V/MHz] for quick MHz setting. Ñ Push [ECLR] to exit set mode. NOTE: The offset frequency can be set in a memory channel temporarily. However, the set contents are cleared once the memory/call mode is selected. To store the offset frequency permanently, overwrite the channel information. Push the selected band's tuning dial to exit set mode. 30 5 REPEATER OPERATION I Auto repeater (U. S. A. version only) USING INITIAL SET MODE D Frequency range and offset direction FREQUENCY RANGE 145. 200­145. 495 MHz 146. 610­146. 995 MHz 147. 000­147. 395 MHz 442. 000­444. 995 MHz 447. 000­449. 995 MHz DUPLEX DIRECTION "DUP­" appears "DUP" appears "DUP" appears "DUP­" appears The U. S. A. version automatically activates the repeater settings (DUP or DUP­ and tone encoder ON/OFF) when the operating frequency falls within the general repeater output frequency range and deactivates them when outside of the range. D Setting the auto repeater function ON/OFF Push [POWER] to turn power OFF. While pushing [(VOL)SET L] (left side), turn power ON to enter initial set mode. Push [SET L] one or more times until the "rPt" display appears as shown below. Rotate the left-hand tuning dial to turn the auto repeater function ON ("rPt-r1" or "rPt-r2") or OFF ("rPt-oF"). · "rPt-r1" and "rPt-r2" automatically set the duplex setting and duplex/tone encoder settings, respectively. Push [POWER] momentarily to exit initial set mode. DUP DUP T Duplex setting: Tone encoder: Automatic ON Automatic OFF Automatic ON Automatic ON 31 MEMORY OPERATION I General description The transceiver has 99 regular memory channels plus 6 scan edge memory channels (3 pairs) on each band; each of these can be individually programmed with the following data. 15­19) · Duplex direction (DUP or DUP­) and its offset frequency (pgs. 27, 30) · Subaudible tone encoder or tone squelch*1 and its tone frequency (pgs. 45) *1An optional UT-104 TONE SQUELCH UNIT is necessary. *2Except for the scan edge memory channels. Select the memory channel to be transferred: Select memory mode by pushing the selected band's [M/CALL] once or twice ("!" appears). Rotate the selected band's tuning dial to select the memory channel. Push [S. MW] momentarily, then rotate the tuning dial to select another memory channel to transfer. · To transfer to the VFO, push and hold [(S. MW)MW] instead of pushing momentarily. Push and hold [(S. MW)MW] to transfer when a momentary push was used in the previous step. 35 MEMORY OPERATION 6 I Memory clearing Contents of programmed memories can be cleared (blanked), if desired. Push [S. MW] momentarily. Select the memory channel to be cleared with the tuning dial. NOTE: Be careful--the contents of cleared memories CANNOT be recalled. · Memory channel 0 and scan edge channels 1A/1b cannot be cleared. Push [S. MW] briefly, then a second time for 1 sec. · 3 beeps sound, then the frequency is cleared. · "!" flashes continuously. · Scan edges and call channel cannot be cleared. Memory clearing may not be performed from the microphone. Push any switch to stop the flashing. [EXAMPLE]: Clearing memory channel 20. Push S. MW MW momentarily Rotate 1 5 9 Push S. MW MW briefly, then push S. MW MW again for 1 sec. Push 36 7 CALL CHANNEL OPERATION I Transferring call channel contents Push the desired band's tuning dial. Select the call channel by pushing the selected band's [M/CALL] once or twice. I Calling up a call channel Each band has an independent call channel to store a mostoften-used frequency for quick recall. Push the desired band's [M/CALL] once or twice to display a large "C" in the memory channel readout. · To transmit on the call channel, select the desired band as the main band in advance. Push [S. MW] momentarily, then rotate the tuning dial to select another memory channel to transfer. · To transfer to the VFO, push and hold [(S. MW)MW] instead of pushing momentarily. · A large "C" appears. Push the same band's [V/MHz] or [M/CALL] to exit the call channel. Push and hold [(S. MW)MW] to transfer when a momentary push was used in the previous step. Large "C" shows the call channel is selected. Small "c" shows VFO mode was selected from the call channel. MW Ä Push [BAND] to select the desired band, if necessary. A Å Push [(MR)CALL] for 1 sec. to select the call channel. Ä Push [BAND] to select the desired band, if necCALL Ç Push [FUNC], then [EMW] momentarily. · To transfer to the VFO, push [FUNC] then [EMW] instead of pushing [EMW] momentarily. essary. to select the call channel. É Push [FUNC] then [EMW] for 1 sec. to transfer when momentarily pushing [EMW] in step . 37 CALL CHANNEL OPERATION 7 I Programming a call channel In addition to an operating frequency, duplex information and subaudible tone information (tone encoder or tone squelch* ON/OFF and its frequency) can be programmed into the call channel. *An optional UT-104 is necessary. CONVENIENT The call channel can also be programmed from the VFO directly (similar to memory programming). MW Ä Push [BAND] to select the desired band, if necessary. Push the desired band's tuning dial. Select the call channel by pushing the selected band's [M/CALL] once or twice.
