Starting Out with Your OmniBook Setting Up 5. Adjust the display Brightness Contrast Some OmniBook models have just a brightness control, while others have both brightness and contrast controls. • If there is only a brightness symbol: Press the ∧ and ∨ buttons above the keyboard to adjust the brightness. • If there is a gray contrast symbol and an orange brightness symbol: Press the ∧ and ∨ buttons above the keyboard to adjust the contrast. Hold down the (orange) FN key and press the same two buttons to adjust the brightness. Note Keep in mind that a higher brightness setting gives a shorter battery operating time—because the internal light is using more power.
This may affect the operating time by as much as 1 hour or so. (The contrast setting doesn’t affect the operating time.) When you turn on your OmniBook, the display usually takes 1 minute or more to reach its normal brightness. The cooler the environment, the longer it takes. 1-7
