Trackerball (MDD-A110)
30 The trackerball controls the on-screen cursor and is used for example to change
parameters, select modes, functions, objects, highlight data, select text. The cursor is
shown as an arrow, cross-hair or square on the screen, depending on the function being used
(refer to the operating instructions in KH3200 for full details).
31 Three pushbuttons are associated with the trackerball and are used to implement the
functions. The 'Cursor Cue' window on the screen indicates the current function of the
three pushbuttons.
32 The trackerball is blue and has LED backlighting. The brightness of the visual display
unit and trackerball backlighting is fully controllable from the Visual Display Unit,
thereby providing suitable backlighting levels for different ambient lighting conditions, e.g. day,
dusk, night. The backlighting can be switched off, if required.
