The marker is moved to the highest on-screen signal peak (turns the marker on if
it is not active) independent of the detection threshold.
The first press turns on a single marker at center screen; its position is control-
lable with the FREQ/MKRS knob. A second press fixes the position of the first
marker and turns on a second marker (delta marker mode); its position is
controllable with the FREQ/MKRS knob. A third press turns off both markers.
Each key, respectively, jumps the moveable marker from its current position to
the next on-screen signal peak to the left or right. Signals must be above the
detection threshold (see Setting the Signal Threshold on page 6–22).
