LCD Brightness and Eye Stain
*13
Your LCD display has a brightness approaching that of a TV device. We
recommend that you adjust the brightness of your LCD to a comfortable
level to prevent possible strain on your eyes.
Safety Use for TV Tuner
*14
If you have to operate your PC during a thunderstorm and are connecting
the TV tuner to an outside antenna, you should operate your PC using AC
power mode. The AC adapter offers some protection against (but does not
entirely prevent) possible electric shock caused by lightning. For complete
protection, do not operate your PC during a thunderstorm.
