Adjusting the Display Contrast

Adjusting the Display Contrast

The brightness and contrast of the display can depend on

room lighting, battery freshness, and viewing angle.
To adjust the contrast:
1. Press and release the yellow - key.
2. Press and hold $ (to darken the screen) or # (to lighten

the screen).

As you change the contrast setting, a number from 0 (lightest)

to 9 (darkest) in the top-right corner indicates the current

setting. You may not be able to see the number if the contrast

is too light or too dark.
