Each mode has been allocated a default tuning increment setting:

FM: 100 Hz
 SSB / CW / AM: 10 Hz
Changing the operating mode will reset the current setting to default values.
11.5 STEP-VFO Control
Operation with knob STEP-VFO allows VFO tuning with further increments.
The STEP-VFO Control is placed in the cluster MODE. The control enables
tuning in 10 kHz, 100 kHz and 1 MHz increments.
Pushing the knob activates the STEP-VFO function:

A cursor appears at the 100 kHz digit of the frequency display:
 Turning the knob will now tune the VFO by 100 kHz steps.
Pushing the knob a second time will move the cursor to the 10 kHz digit.
Turning the knob will result in tuning the VFO by 10 kHz steps.
Pushing the knob a third time will move the cursor to the 1 MHz digit –
hence tuning can now be established by 1 MHz steps.
Pushing the knob again will result in a movement of the curser again to
the 100 kHz digit, then 1 kHz, 1 MHz, and so on.
Neither pushing the knob nor turning the control for more than 3 seconds will
terminate the STEP-VFO function. If re-activated by pushing the knob the cursor
will appear at the last used position.
When power up the PT-8000A and STEP-VFO will be activated the curser will
initially occur at the 100 kHz position.
