Marker 1 was chosen because it is selected as the delta marker reference. To change reference markers, select Delta Mkr Ref .

Select M2 as the reference. Watch the display change to indicate:

--> D E L T A M K R ( 3 - 2 ) : 1 2 0 0 . 0 0 0 0 0 0 M H z

You can choose any of the five markers as a reference, but when delta marker is on, if the reference marker has a frequency value higher than the last active marker, the difference between the frequencies

is negative and is displayed as such by the synthesizer. The CRT display continues to intensify the difference between the two markers.

When delta marker is showing in the active entry area, the ENTRY area is active. Rotate the rotary knob and watch the frequency difference change. The last active marker (in this case, marker 3) changes frequency value, not the reference marker.
