ROGRAMMABLE
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.
