MEMORY SCAN

GROUP 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.

1Select Time-operated or Carrier-operated via Menu No. 10.

2Press [M/V] to enter Memory Recall mode.

3Turn the SQL control to adjust the squelch to threshold.

4Press [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].

5To 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.

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:

Group 0	Ch 00, Ch 01, Ch 02,			•	•	•	•	Ch 09
Group 1	Ch 10, Ch 11, Ch 12,			•	•	•	•	Ch 19
Group 2	Ch 20, Ch 21, Ch 22,			•	•	•	•	Ch 29
•	•	•	•	•	•	•	•	•
•	•	•	•	•	•	•	•	•
•	•	•	•	•	•	•	•	•
Group 9	Ch 90, Ch 91, Ch 92,			•	•	•	•	Ch 99

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.

1Select Time-operated or Carrier-operated via Menu No. 10.

2Press [MR] to enter Memory Recall mode.

3Turn the SQL control to adjust the squelch to the threshold.

4Press 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.

5Release [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].

6To 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:

◆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.
