Bezel Buttons. The four unlabeled buttons directly below the display are referred

The function of the arrow buttons is dependent on the current state of the
instrument. For the Waveform and Audio display modes, they control signal
positioning. For the Vector display mode, they control vector phase, with the

coarse adjustment.
The arrow buttons retain their default function for the reduced display when the
Waveform-in-Picture display mode is selected. When the Configuration menu is
displayed, the
Y and B buttons operate the menu category selection, while the A
and " buttons retain their default function for the current display mode.
