Changing The Display Settings - Simrad IS20 Manual

5.5 Changing the display settings

To optimize the readability under different light
conditions, the display is controlled by 4 settings:
− Display contrast
− Display background
− Light color
− Light level
Display background and light are grouped in Day and
Night profile settings, making it possible to quickly
switch between these settings by using the Light key.
Refer Backlighting, page 12.
Light color and light level also applies for the keys!
Display contrast
The contrast controls the difference between the
text/graphics and the display background. Level 9 gives
the highest contrast.
