[QMB]key
Press and hold this key for more than one second to write the frequency and the data pres-
ently set for VFO-A onto the quick memory bank (QMB).
○ Once all 5 QMB memories have data on them, previous data will be over-written on a
rst-in, rst-out basis.
○ 5 QMB memory channels are provided. Press this key briey to recall the data written
onto the quick memory banks (QMB)one by one.
○ To change the frequency in the recalled quick memory bank (QMB), rotate the MAIN
DIAL.
[MuV]key
This key will copy the saved data from the written memory channel to VFO-A.
Press this key. à The “MEMORY CHANNEL” list screen is displayed. àPress the MULTI
function knob to select the desired channel àPress this key. àThe currently selected
memory channel data is copied to VFO-A.
[VuM]key
This key is to save the data from VFO-A to the memory channel.
Press this key. à The “MEMORY CHANNEL” list screen is displayed. àPress the MULTI
function knob to select the desired channel. àPress this key. à The current operating
data is copied to the selected memory channel.
○ When the “MEMORY CHANNEL” list screen is displayed, press the [A]/[B]/[C]key to edit
the selected memory channel.
[V/M]key
This key toggles frequency control between the VFO and the memory systems.
○ When the memory channel data is recalled, the Memory channel number is displayed
like “ ”. The previously selected Memory Channel is recalled.
○ Rotate the MULTI function knob to change the memory channel number.
○ While operating on a memory channel, Rotate MAIN DIAL. à the “Memory Channel
Number” will be replaced by the MEMORY TUNE indicator “ ”.
“ ” indicates that the operating frequency in the Memory Channel is temporarily
changed.
Press
[V/M] key in this state. àPrevious memory channel data is restored.
[A/B]key
Press this key. à The frequency and memory channel data, of VFO-A and VFO-B are ex-
changed.
Press and hold this key. à The frequency and data values of VFO-A are copied to VFO-B.
[BAND(MODE)] key
Press this key. à The “BAND SELECT” screen will appear in the display. àRotate the
DIAL knob to select the desired frequency band (operating band). àThe selected frequen-
cy band is set automatically in one second and the display returns to normal operation.
Press and hold this key. à
The “MODE SELECT” screen will appear in the display.
à
Ro-
tate the DIAL knob to select the radio modulation form (operating mode).
àThe selected
mode is set automatically in one second and the display returns to normal operation.
[FAST]key
Pressing this key will change the tuning of the MAIN DIAL to a higher step rate.
Press this key. à“ ” is displayed. àThe main dial frequency tuning rate doubles.
[A]/[B]/[C]keys
These three keys are user programmable, allowing quick access to often used features.
○ [A]/[B]/[C] keys are assigned the following functions as default settings:
● [A](SFT): IF SHIFT function
IF SHIFT permits moving the DSP lter passband higher or lower, without changing the pitch of the incom-
ing signal, and thus reduces or eliminates interference.
Press this key à The IF SHIFT screen will appear in the display àRotate the MULTI function knob to the
left or right to reduce interfering signals.
Press and hold the MULTI function knob to restore the IF SHIFT setting to the factory default.
● [B](SCP): The SCOPE function
The SCOPE function provides a spectrum display of the band conditions.
Press this key. àthe band condition (spectrum) is displayed.
When the SCOPE function is active, the [A]/[B]/[C] keys are automatically changed to the below operations.
[A](SPN) key: This key changes the displayed bandwidth. Available selections are 750 kHz, 375 kHz,
150 kHz, 75 kHz, or 37.5 kHz ranges.
[B](SWP) key: Each time the [B](SWP) key is pressed, a new scan of the spectrum scope is shown on
the LCD display.
[C](LV1-3) key: This key changes the reference level.
○ While the Spectrum Scope is activated, Press the MULTI function knob, and then rotate it to adjust the
operating frequency tuning steps of VFO-A by the 500 kHz.
● [C](NB): Noise Blanker function
The IF Noise Blanker can signicantly reduced noise that is caused by automotive ignition systems.
