Starting Out with Your OmniBook Setting Up the OmniBook To adjust the display • Press the ∧ and ∨ buttons above the keyboard 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. 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. 1-8
