7 SCANS ■ Scan types PROGRAMMED SCAN/AUTO MEMORY WRITE SCAN Repeatedly scans between two scan edge frequencies (scan edge memory channels P1 and P2). Auto memory write scan automatically memorizes paused frequencies into memory channels 80 to 99. Scan edge P1 or P2 Scan edge P2 or P1 Scan Jump This scan operates in VFO mode. SELECT MEMORY SCAN Repeatedly scans all select memory channels. S (select) BLANK Mch 2 Mch 3 Mch 4 Mch 1 S (select) S (select) Mch 5 Mch 99 Mch 7 Mch 6 S (select) S (select) This scan operates in memory mode. MEMORY SCAN Repeatedly scans all programmed memory channels. S (select) BLANK Mch 2 Mch 3 Mch 4 Mch 1 S (select) S (select) Mch 5 Mch 99 Mch 7 Mch 6 S (select) S (select) This scan operates in memory mode. PRIORITY WATCH Repeatedly watches a memory channel. 5 sec. VFO frequency 125 msec. Memory channel This scan operates in VFO mode. ■ Preparation • Channels For programmed scan/auto memory write scan: Program scan edge frequencies into scan edge memory channels P1 and P2. For memory scan: Program 2 or more memory channels except scan edge memory channels. For select memory scan: Designate 2 or more memory channels as select memory channels. To designate the channel as a select memory channel, select a memory channel, then push [SEL] in the scan screen (memory mode) or in the memory channel screen. For priority watch: Program 1 or more memory channels. • Scan resume ON/OFF You can select the scan to resume or cancel when detecting a signal, in set mode. Scan resume ON/OFF must be set before operating a scan. See p. 31 for ON/ OFF setting and scan resume condition details. • Scan speed Scan speed can be selected from 2 levels, high or low, in set mode. See p. 31 for details. • Squelch condition ❍ Scan starts with squelch open For programmed scan: When tuning step is 1 kHz or less: The scan continues until it is stopped manually- it does not pause* even if signals are detected. * The scan is paused when the squelch is closed and then opened (scan resumes after 10 sec. has passed when the scan resume is ON; scan is cancelled when the scan resume is OFF). When tuning step is more than 5 kHz: The scan pauses on each step when the scan resume is ON; not applicable when the scan resume is OFF. For memory scan: Scan pauses on each channel when the scan resume is ON; not applicable when the scan resume is OFF. ❍ Scan starts with squelch closed Scan stops when a signal is detected. • If the scan resume is set to ON in scan set mode, the scan pauses for 10 sec. when detecting a signal, then resumes. When a signal disappears while scan is paused, scan resumes 2 sec. later. 25
