To limit scanning (and manual tuning) within a particular frequency range, you can use the Programmable Memory Scan-
ning (PMS) feature, which utilizes nine special-purpose memory pairs (“
P1L P1L
P1L P1L P1L
/
P1U P1U
P1U P1U P1U
” through “
P9L P9L
P9L P9L P9L
/
P9U P9U
P9U P9U P9U
”). The PMS fea-
ture 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 fre-
quencies into the memory pair “
P1L P1L
P1L P1L P1L
” and “
P1U P1U
P1U P1U P1U
”, re-
spectively, or any other “L/U” pair of memories in the
special PMS memory area. See page 92 for details re-
garding memory storage.
2. Press the [ V/M
] button to enter the “Memory” mode.

DVICE
:
If you can not enter the “Memory” mode, check to see
if the transceiver is in VFO-B mode (the green [
VFO-
B
(
RX
)] Indicator/Switch is illuminated). If so, press
the [ VFO-A
(
RX
)] Indicator/Switch to return operation
to VFO-A. Now, press the [ V/M
] button to enter the
“Memory” mode.
3. Press the [ MCH
] button momentarily. The imbedded
LED inside the switch will glow orange.
4. Rotate the [ CLAR/VFO-B
] knob to select memory
channel “
P1L P1L
P1L P1L P1L
” or “
P1U P1U
P1U P1U P1U
”.
5. Rotate the [ SQL
] knob so that the background noise is
just silenced.
6. Turn the Main Tuning Dial knob slightly (to activate
memory tuning). Tuning and scanning are now limited
to the range within the P1L/P1U limits until you press
the [
V/M
] button to return to memory channel or VFO
operation.
7. Press and hold in the microphone’s [ UP
] or [
DWN
]
key for one second to start scanning in the specified
direction.
A
DVICE
:
ˆ If the scanner halts on an incoming signal, the deci-
mal point between the “MHz” and “kHz” digits of
the frequency display will blink.
ˆ If the incoming signal disappears, scanning will re-
sume in about five seconds.
ˆ 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.
ˆ If the scan has paused on a signal, pressing the
microphone’s [ UP
] or [
DWN
] key will cause scan-
ning to resume instantly.
8. If you rotate the Main Tuning Dial knob in the oppo-
site direction from the current scanning direction (in
other words, you rotate the dial to the left when scan-
ning toward a higher frequency), the direction of the
scan will reverse.
9. If you press the microphone’s PTT switch during scan-
ning, the scanner will halt at once. Pressing the
PTT
switch during scanning will not cause transmission.
