To limit scanning (and manual tuning) within a particular frequency range, you can use the Programmable
Memory Scanning (PMS) feature, which utilizes two special-purpose memory pairs (“MEM-P1L/MEM-P1U” and
“MEM-P2L/MEM-P2U”). 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 “MEM-P1L” and
“MEM-P1U”, respectively, or “MEM-P2L” and
“MEM-P2U”. See page 58 for details regarding
memory storage.

2. Press the [F] button, followed by the [SCAN/PMS]
button.
3. Rotate the [DSP/SEL] knob to select “PMS-1”
“PMS2” or “PMS1+2”.

7. If you want to change direction of the scan while it
is underway, rotate the [MAIN DIAL] knob one click
in the opposite direction (in this case, one click
counter-clockwise). You will see the scanner re-

8. In FM/AM mode, when the scanner encounters a
signal strong enough to open the squelch, the
scanner will halt for five seconds, after which scan-
ning will resume.
In the SSB/CW and SSB-based Data modes,
when the scanner encounters a signal strong
enough to open the squelch, the scanner will step
across the signal very slowly, giving you time to
stop the scan, if you like.

the scanner to resume scanning after five seconds;
you may change it, however, to resume only after the
