Set a "Skipped" Channel During Memory Scan Operation
Some continuous-carrier stations will seriously impede scanner operation and they may be "skipped" during scanning, if
you like.
1. Select the Memory mode by pressing the [V/M] key, if necessary.
2. Rotate the DIAL to select the Memory channel to be skipped.
3. Press and hold the [SCN] key for 1/2 second and the " " icon will appear on the display. The current Memory ch-
annel will now be ignored during scanning. The " " icon will also appear when you recall the "skipped" memory
channel manually.
4. To cancel the "skipped" feature, press and hold the [SCN] key for 1/2 second again to select "OFF".
Preferential Memory Scanning
Set up a "Preferential Scan List" of channels which you can "flag" within the memory system. These channels are design-
ated by a " " icon when you have selected them.
When you select Preferential Memory Scan mode and start scanning, only those channels bearing the " " icon will be
scanned.
How to set up and use the Preferential Scan List:
1. Select the Memory mode by pressing the [V/M] key, if necessary.
2. Rotate the DIAL to select the channel which you wish to add to the Preferential Scan List.
3. Press and hold the [SCN] key for 1/2 second, several times if necessary, so as to make the " " icon appear by the
channel designator.

Before you begin to scan, select the way in which you would like the scanner to resume scanning after it halts on a signal.
To set the scan-Resume mode:
1. Short press the [SET] key to enter Menu mode.
2. Rotate the "Main" band DIAL to select Menu # 25 (SCAN).
3. Short press the "Main" band DIAL knob, then rotate the "Main" band DIAL to select the desired scan-resume mode.
TIME: the scanner will halt on a signal it encounters, and will hold 5 seconds. If you do not take action to disable the sca-
nner within 5 seconds, the scanner will resume even if the stations are still alive.
BUSY: The scanner will halt on a signal it encounters. 2 seconds after the carrier has dropped as the other station(s) ce-
ased transmission, the scanner will resume.
4. Press the [SET] key to save the new setting and exit to normal operation.
Note: the default setting for scan-resume mode is "TIME".
VFO Scanning
1. Select the VFO mode by pressing [V/M] key, if necessary.
2. Press the [SCN] key to start scanning.
3. Rotate the "Main" band DIAL to change scanning frequency direction.
4. If and when the scanner encounters a signal strong enough to open the squelch, the scanner will halt temporarily; the
decimal point of the frequency display will blink during this "Pause" condition.
5. The scanner will then resume according to the Scan-Resume mode selected in previous step.
6. To cancel scanning, press the [SCN] key again.
Memory Scanning
