Right next to the help button on the bottom left corner of the display screen there are contrast buttons. One will make the screen bright, the other wil make it darker. You may set the intensity from 1-100. When you set the intensity to the level you desire, press the write button on the right side of the screen to save your changes.Quincy
Doron Sorry to have to tell you that the screen is not non-reflective and however much you alter the contrast you will NOT be able to see the screen outdoors when the sun shines even with dark glasses on... Rog
