5.1 Scanning
This function automatically searches for active frequencies to
help you locate a signal that you wish to receive.
There are two types of scanning; Busy scan and Timer scan.
The default is set to Busy ("bUSY") scan.
Switching between those two types can be done in the Setting
mode. (See on P.26)
Busy scan:
If no signal is monitored after scanning stops, it will search for
another frequency.
Timer scan:
Even if a signal is detected after scanning stops, it will switch to
the next frequency after 5 seconds.
•
While it is scanning, the decimal point (.) on the LCD blinks.
•
Even when it is scanning, a scan will be suspended and the
squelch will open temporarily when you hold the MONI key down.
Scanning will continue when you release the MONI key.
•
While it is scanning, the scanning direction can be changed
with a dial operation. Scanning starts in the direction of the
last dial operation. (up or down)
•
Press any key other than the MONI key to stop scanning.

VFO Scan
In the VFO mode, scanning is performed to detect signals
using the tuning step you set in advance (see on P.15) for any
frequencies in the specified band.
1. Press the
key to switch to the VFO mode.
2. While holding the
key down, rotate the dial to
display "vFo" on the LCD.
3. Release the
key.
Scanning will be performed with the selected tuning step in the
direction of the last dial operation. (up or down)
4. Rotate the dial in the clockwise direction to scan in the
UP direction.
Conversely, rotate the dial in the counter-clockwise
direction to scan in the DOWN direction.
5. Press any key other than the MONI key to stop
scanning.
■
Program Scan
Scanning is performed to detect signals between a specified
range of frequencies. Both the higher and lower limit of the
scan range need to be set in advance. Otherwise, the following
operations can't be done.
A programmed pair of frequencies (higher and lower limit) is
called a "program scan channel". You can program up to 5
pairs of frequency ranges.
For more information on how to program, please refer to
"Programming a Memory Channel" on P.16.
1. Press the
key to switch to the VFO mode.
2. While holding the
key down, rotate the dial to
select a program scan channel, such as P0A and P0b,
to search.
3. Release the
key.
When you have selected "A" side, scanning will be performed in
the direction of side "b".
Conversely, when you have selected "b" side, scanning will be
performed in the direction of side "A".
Whichever you choose, it scans within the same range.
