12 SCAN MEMORY SCAN Memory Scan monitors all memory channels in which you have stored frequencies (All-channel Scan) or only a desired group of memory channels (Group Scan). Scan automatically stops at a channel where a signal is present, regardless of the operating mode. The transceiver will either remain on that channel for a short time (Time-Operated mode) or until the signal drops out (Carrier-Operated mode). Use Menu No. 11 to select the mode. The default is "to" (TimeOperated). SCAN RESUME METHOD The transceiver stops scanning at the frequency (or memory channel) where a signal is detected. It then continues scanning according to which resume mode you have selected. You can choose one of the following modes. The default is Time-operated mode. • Time-Operated mode ("to") The transceiver remains on a busy frequency (or memory channel) for approximately 6 seconds, then continues to scan, even if the signal is still present. • Carrier-Operated mode ("co") The transceiver remains on the busy frequency (or memory channel) until the signal drops out. There is a 2 second delay between signal dropout and scan resumption. 1 Press [MENU/ F.LOCK] to enter Menu mode. 2 Turn the MULTI control to select Menu No. 11. 3 Press [ ]/ [ ] to select "to" (Time-Operated) or "co" (Carrier-Operated). 4 Press [MENU/ F.LOCK] to complete the setting and exit Menu mode. You can lock out the memory channels that you prefer not to monitor while scanning. To do this, refer to "Memory Channel Lockout" {page 54}. ALL-CHANNEL SCAN Use the following procedure to scan all the memory channels that contain frequency data in sequence, ignoring the Memory Group number. 1 Select Time-operated or Carrier-operated mode via Menu No. 11. 2 Press [A/B / M/V] (1 s) to enter Memory Recall mode. 3 Turn the SQL control to adjust the squelch threshold to mute the speaker. 4 Press [SCAN/ SG.SEL] (1 s) to enter Scan Group Select mode. • Turn the MULTI control to select the Memory channel group. • MGROUP-0 represents Memory channel 0 ~ 9, MGROUP-1 represents Memory channel 10 ~ 19 and so on up to MGROUP-9 which represents Memory channel 90 ~ 99 {page 53}. 5 As you select the Memory Groups using the MULTI control, press [ ] to select "oFF" for all Memory Groups. 6 Press [SCAN/ SG.SEL] to return to Memory Recall mode. 7 Press [SCAN/ SG.SEL] to start All-channel Scan. • Scan starts from the current memory channel and ascends up through the channel numbers. (The scan direction cannot be changed.) • To jump to a desired channel while scanning, turn the MULTI control, or press Mic [UP]/ [DWN]. 8 To stop Scan, press [SCAN/ SG.SEL] or [MTR/ CLR]. Note: ◆ If you have turned the SQL control clockwise, far beyond the squelch threshold, Scan may fail to stop at a channel where a signal is present. If this happens, turn the SQL control slightly counterclockwise. ◆ Starting Memory Scan switches OFF the RIT and XIT functions. 58
