To limit scanning (and manual tuning) within a particular frequency range, the Programmable Memory Scanning (PMS)
feature utilizes nine special-purpose memory pairs (“
P-1L
/
P-1U
” through “
P-9L
/
P-9U
”). The PMS feature is especially
useful in helping you to observe any operating sub-band limits, which apply to your Amateur license class.
1. Store the Lower and Upper tuning/scanning limit
frequencies into the memory pair “
P-1L
” and “
P-1U
”,
respectively, or any other “L/U” pair of memories
in the special PMS memory area. See page 98 for
details regarding memory storage.
2. Press the
V/M
button to enter the “Memory” mode.
3. Press the
F(M-LIST)
button, then touch
[
MCH
]
on
the TFT display. The LEDs indicating the Memory
mode will illuminate.

4. Rotate the

knob to select memory channel

”.
5. Press the
F(M-LIST)
button, then touch
[

]
on
the LCD. Rotate the
MULTI
knob so that the back-
ground noise is just silenced.
6. Turn the Main Tuning Dial knob slightly (to activate
memory tuning). Tuning and scanning are now lim-
ited to the range within the P-1L/P-1U limits until
the
V/M
button is pressed again to return to memory
channel or VFO operation.
7. Press and hold in the microphone
UP
or
DWN
but-
ton for one second, or press the
F(M-LIST)
button
followed by
[
SCAN
]
to start scanning in the speci-
ed direction.
Advice:
If the scanner halts on an incoming signal, the deci-
mal point between the “MHz” and “kHz” digits of
the frequency display will blink.
If the incoming signal disappears, scanning will re-
sume in about ve seconds.
On the SSB/CW and SSB-based Data modes, the
scanner will pause on a received signal, then will
step across the signal very slowly, giving you time to
stop the scan, if you like. However, in these modes
on the VFO, the scanner does not stop.
If the scan has paused on a signal, pressing the mi-
crophone
UP
or
DWN
button, or touching
[
SCAN
]
on the LCD will cause scanning to resume instantly.
If the Main Tuning Dial knob is rotated while scan-
ning is in progress, the scanning will continue up
or down in frequency according to the direction of
the Dial Knob rotation. (in other words, if the dial
is rotated to the left when scanning toward a higher
frequency, the direction of the scan will reverse.)
If the microphone
PTT
button is pressed during
scanning, the scanner will halt at once. Pressing the
PTT
button during scanning will not cause transmis-
sion.
