[. . . ] 50) w Push [A·FUNC], then push [C·MR] momentarily. · "--" and "X" flashes. e Push [Y]/[Z] to select the target memory. · When "dial" is assigned [VOL], rotate [VOL] to select the memory channel. 50) r Push [A·FUNC], then push [C·MR] for 1 sec. · Memory mode is selected and the contents are transferred to the target memory. D Clearing a memory q Push [A·FUNC], then push [C·MR] to enter the memory transfer mode. · "X" and a memory channel number flash. w Push [Y]/[Z] to select the memory channel to be cleared. · When [VOL] is assigned as "dial, " rotate [VOL] to select the memory channel. 50) · The call channel cannot be cleared. e Push [A·FUNC], then push [C·MR] momentarily. r Push [A·FUNC], then push [C·MR] for 1 sec. · Perform step e and r operations within 1. 5 sec, otherwise the memory clearing is cancelled and the transceiver returns to the memory mode. · The contents of the selected memory are cleared. t Push [D·CLR] to return to regular operation. 26 I Programming a DTMF code The transceiver has 5 DTMF memory channels (d0 to d4) for storage of often-used DTMF codes of up to 24 digits. q Push [A·FUNC], then push [0·DTMF-M] to 7 DTMF MEMORY enter the DTMF memory. · One of "d0" to "d4" appears. w Rotate [VOL] to select the desired channel. e Push [A·FUNC], then push [0·DTMF-M] for 1 sec. 50) e Push [D·CLR] to stop the scan. D Setting skip channels In order to speed up the scan interval, you can set memory channels you don't wish to scan as skip channels. q Push [C·MR] to select memory mode, if necessary. · "X" appears. w Select a memory channel to set as a skip channel. e Push [A·FUNC], then push [6·SKIP] to toggle the skip setting ON and OFF. · "SKIP" appears when the channel is set as a skip channel. 31 SCAN OPERATION 8 I Priority watch Priority watch checks for signals on "priority channels" while operating on a VFO frequency. D Memory or call channel watch While operating on a VFO frequency, memory or call channel watch monitors for signals in the selected memory or call channel every 5 sec. q Select the desired memory channel or the call channel. w Push [D·CLR] to select VFO mode. e Push [A·FUNC], then push [7·PRIO] to start watching. · VFO is displayed, then the decimal point ". ", on the frequency readout flashes. · The priority channel is monitored every 5 sec. · When the signal is detected on the priority channel, the watching is paused according to the setting of the scan resume condition. r Push [D·CLR] to stop watching. D Memory scan watch While operating on a VFO frequency or the call channel, memory scan watch monitors for signals in each memory channel in sequence, every 5 sec. q Push [C·MR] to select memory mode, if necessary. · "X" appears. w Push [A·FUNC], then push [5·SCAN] to start the memory scan. e Push [A·FUNC], then push [7·PRIO] to start the watching. · VFO is displayed, then the decimal point ". ", on the frequency readout flashes. · When the signal is detected on the priority channel, the watching is paused according to the setting of the scan resume condition. r Push [D·CLR] to stop the watching. 32 8 SCAN OPERATION USING I Scan resume condition When a signal is received during scanning, the scan resume condition determines what action the transceiver takes.
