Technical information

m If you have a mouse in addition to the trackpad, or if you have removed the trackpad from the
keyboard, position the mouse or trackpad at the same height as your keyboard. Allow adequate
space to use the mouse comfortably.
m Adjust the computer so the top of the screen is slightly below your eye level when you’re sitting at
the keyboard. (You may need to place something under it or raise your work surface.) The best
distance from your eyes to the screen is up to you, although most people seem to prefer 18 to 28
inches (45 to 70 cm).
m Position the screen to minimize glare and reflections on the screen from overhead lights and
windows. The computer’s stand lets you set the screen at the best angle for viewing, helping to
reduce or eliminate glare from lighting sources you can’t move.
