Display Contrast Keys
You can adjust the contrast of the display by pressing the decrease 
contrast key   or the increase contrast key  .
Pressing the decrease contrast key and holding it down causes the 
display background to gradually darken in comparison to the text on 
the display. The minimum contrast setting is not a completely black 
display. Some contrast between the background and the text will still be 
visible.
Pressing the increase contrast key and holding it down causes the 
display background to gradually brighten in comparison to the text on 
the display. If the background does not appear to change, it is probably 
set to the maximum contrast.
Display contrast is a persistent state; it is not affected by an instrument 
preset or by a power cycle.
