(

PMS

)

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

[

]

button, followed by the

[

PMS/SCAN

]

button.

3. Rotate the

[

DSP/SEL

]

knob to select “PMS-1”

“PMS2” or “PMS1+2”.

PMS-1: The scanner will be limited within the

frequency range programmed in the

memory pair “MEM-P1L/MEM-P1U”.

PMS-2: The scanner will be limited within the

frequency range programmed in the

memory pair “MEM-P2L/MEM-P2U”.

PMS-1+2: The scanner will be limited within the

frequency ranges programmed by both

memory pairs (“MEM-P1L/MEM-P1U”

and “MEM-P2L/MEM-P2U”).

If a memory pair is vacant, the PMS-1+2 selec-

tion is not available.

4. Press the

[

PMS/SCAN

]

button.

5. Rotate the

[

SQL/RF GAIN

]

knob just to the point

where the noise is silenced and the “ ” indi-

cator on the display turns off.

6. Press the

[

PMS/SCAN

]

key to initiate upward

scanning (toward higher frequencies or higher

memory channel numbers).

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-

verse direction and scan down in frequency.

You may change the direction of the scanner by

pressing and holding the microphone’s

[

]

[

DWN

]

key for one second, if you are using the

optional MH-31A8J Hand Microphone or MD-

100A8X Desktop Microphone.

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.

ADVICE:

You may select the manner in which the scanner re-

sumes while it has paused on a signal, using Menu

Item “SCN RES” The default “5Sec” setting will cause

the scanner to resume scanning after five seconds;

you may change it, however, to resume only after the

carrier has dropped out, if you like See page 83.
