 (PMS) O

To limit scanning (and manual tuning) within a particular frequency range, you can use the
Programmable Memory Scanning (PMS) feature, which utilizes five special-purpose memory
pairs (“M-P1L

/M-P1U” through “M-P5L/M-P5U”). The PMS feature is especially useful in

helping you to observe any operating sub-band limits which apply to your Amateur license
class.

PMS setup is simple to accomplish:

1. Store the upper and lower frequency limits of the desired range into the PMS memory

pair (“M-PxL” and “M-PxU”), where the “U” channel represents the Upper frequency
limit, and the “L” channel represents the Lower frequency limit.

2. Press the [FUNC] key momentarily, then rotate the SELECT knob, as needed, until

Multi Function Row “f” [ARTS, SRCH, PMS] appears on the display.

3. Press the [C](PMS) key. The “PMS-x” indication will appear at the upper left corner of

the LCD, signifying that the PMS feature is engaged. Tuning and scanning (by pressing
the [A](SCN) key on the Multi Function Row “g” [SCN, PRI, DW]) are now limited
within the range between the selected PMS memory pair, keeping operation inside this
programmed range.

Example: Limit tuning and scanning to the frequency range 144.30 - 148.00 MHz, to pre-
vent encroachment into the “Weak Signal” (SSB/CW) portion of the 2-meter band:

1. Press the [V/M] key, as necessary, to recall the VFO mode. Tune the SELECT or DIAL

knob to 144.300 MHz.

2. Press the [FUNC] key momentarily, then rotate the SELECT knob, as needed, until

Multi Function Row “b” [MW, SKIP, TAG] appears on the display.

3. Press the [A](MW) key momentarily, then turn the SELECT knob to select memory

channel “M-P1L.”

4. Press and hold in the [A](MW) key for one second to write the VFO frequency into “M-

P1L.”

5. Now, tune the SELECT or DIAL knob to 148.000 MHz.

Press the [A](MW) key momentarily, then turn the SELECT knob to select memory
channel “M-P1U.”

6. Press and hold in the [A](MW) key for one second to write the VFO frequency into “M-

P1U.”

7. Press the [FUNC] key momentarily, then rotate the SELECT knob one click clockwise

to recall Multi Function Row “f” [ARTS, SRCH, PMS].

8. Press the [C](PMS) key momentarily. Tuning and scanning are now limited to the 144.30

- 148.00 MHz range until you press the [V/M] key to return to memory or VFO operation.
