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

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” (Time-
Operated).
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.
