MEMORY SCAN
Memory Scan monitors all memory channels in which
you stored frequencies (All-channel Scan) or only a
desired group of memory channels (Group Scan).
Scan automatically stops at a channel in which a signal
is present. The transceiver remains on the same
channel for either a short time (Time-operated mode) or
until the signal drops (Carrier-operated mode). Use
Menu No. 10 to select either mode. The default is
Time-operated.
Time-operated mode:
After stopping on a busy channel and waiting
approximately three seconds, Scan checks the channel
again. If the channel is still busy, Scan waits another
three seconds then restarts. If the channel is not busy
three seconds after stopping, Scan restarts immediately.
Carrier-operated mode:
Scan restarts approximately two seconds after the
signal drops.
You can lock out the memory channels that you prefer
not to monitor while scanning. To do this refer to
“Memory Channel Lockout” {page 44}.
ALL-CHANNEL SCAN
Use the following procedure to monitor all memory
channels that contain frequency data.
1 Select Time-operated or Carrier-operated via Menu
No. 10.
2 Press [M/V] to enter Memory Recall mode.
3 Turn the SQL control to adjust the squelch to
threshold.
4 Press [SCAN] to start All-channel Scan.
• Scan starts with the current channel and ascends
up through the channel numbers (this direction
cannot be changed).
• To jump to the desired channel while scanning,
turn the MULTI/CH control, or press Mic [UP]/
[DWN].
5 To stop Scan, press [SCAN] or [CLR].
Note:
◆
If you have turned the SQL control clockwise far beyond the
squelch threshold, Scan may fail to stop at a channel in which a
signal is present. If this happens, turn the SQL control slightly
counterclockwise.
◆
Starting Memory Scan switches OFF the RIT and XIT functions.
GROUP SCAN
For the purpose of Group Scan, the 100 Conventional
memory channels are divided into 10 groups, with each
group containing 10 channels. The channels are
grouped as follows:
You can select a maximum of 10 groups and
sequentially scan the channels that belong to those
groups. Group Scan starts with the smallest group
number and repeats the sequence, for example,
group 3 ➞ group 5 ➞ group 7 ➞ group 3.
1 Select Time-operated or Carrier-operated via Menu
No. 10.
2 Press [MR] to enter Memory Recall mode.
3 Turn the SQL control to adjust the squelch to the
threshold.
4 Press and hold down [SCAN] then, using the
numeric keys, enter the group numbers you desire to
scan, i.e. 3 for group 3, 35 for groups 3 and 5, etc.
5 Release [SCAN] to start Group Scan.
• Scan ascends up through the channel numbers
(this direction cannot be changed).
• To jump to the desired channel while scanning,
turn the MULTI/CH control, or press Mic
[UP]/[DWN].
6 To stop Scan, press [SCAN] or [CLR].
After using Group Scan, enter all group numbers in step
4 or do Full Reset {page 48} to use All-channel Scan
(factory default). Note that doing Full Reset returns all
settings, that you customized, to the factory defaults.
Note:
◆
If you have turned the SQL control clockwise far beyond the
squelch threshold, Scan may fail to stop at a channel in which a
signal is present. If this happens, turn the SQL control slightly
counterclockwise.
◆
When the current channel is within one of the groups that you
select by group number, Scan starts with the current channel.
◆
When the current channel is outside all the groups that you select
by group number, Scan starts with the group number that is
larger than and closest to the group number of the current
channel.
◆
Starting Memory Scan switches OFF the RIT and XIT functions.
