Receiving in the Scanning Mode
Band Scanning
The receiver divides its frequency range (25.0 MHz to
1300.0 MHz) into 17 bands. Band Scanning scans one of
these bands step by step.
1
Set the SQL control to MIN.
2
Press POWER to turn the receiver on.
3
Turn VOL to adjust the volume.
4
Press BAND repeatedly to choose a band.
With each press, the lowest frequency of the next
band will be displayed. Press repeatedly until the
display shows the lowest frequency of the band of
your choice.

Adjust the SQL control (see page 11).
Scanning will start.
When the receiver receives a signal,
fclita'i will light
up and the receiver will go into scanning pause. When
the signal breaks off, the receiver will resume
scanning automatically.
To turn off the power
Press POWER.
Frequency range of the bands

Note
The frequency steps and the detection modes in the list are the
default for each band. You can adjust the frequency step and the
detection mode when you are in Manual Mode. You cannot adjust
them when you are in Scanning Mode.
To resume scanning manually during scanning
pause
Press + or -.
To change scanning direction
Press + or -.
Scanning will restart in ascending direction if you press +,
and in descending direction if you press -.
Note
When you start scanning a new band, scanning will always start in
ascending direction.
To exit Scanning Mode
Press SCAN.
KithWl will disappear from the display and the receiver
enters the Manual Mode. Press again to re-enter the
Scanning Mode.
If you press SCAN for 1 second or longer, the scanning
pause time will go into the 5-second pause mode (see
page 30).
Adjusting the SQL control
Adjustment of the SQL control applies to all modes of
reception.
What the SQL control does
The SQL (squelch) control adjusts the threshold of the
signal intensity that opens the squelch.
When the receiver receives a signal above the threshold,
the squelch will open,
i:wta will appear in the display,
and you will hear the transmission sound.
When the squelch opens during scanning, the receiver
stops scanning. This is called a "scanning pause".
As you turn the SQL control counterclockwise to MIN, the
receiver will pause scanning on weaker signals. But this
may cause the receiver to pause scanning on unwanted
noise signals.
As you turn the SQL control clockwise to MAX, the
receiver will cut off the weaker signals and receive only
stronger signals. If it is turned too far clockwise, on the
other hand, there may be no signal strong enough to cause
a scanning pause.
Adjusting the SQL control
Start from the MIN position and turn it
clockwise towards MAX to the point the miM’i
indication disappears in the display.
When there is a signal above the squelch threshold,
will light up and the receiver pauses scanning. Scanning
will resume automatically when the signal breaks off.
