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.
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.
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.

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.
