are parallel to the floor and your feet are either flat on the floor or on a
footrest.
When using the keyboard, keep your forearms parallel to the floor and your
wrists in a neutral, comfortable position. Try to keep a light touch on the
keyboard and your hands and fingers relaxed. You can change the angle of
the keyboard for maximum comfort by adjusting the position of the
keyboard feet.
Viewing Distance

Height
Adjust the monitor so that the top of the screen is at, or slightly below, eye
level. Place the monitor at a comfortable viewing distance, usually 51 to 61
cm (20 to 24 in.), and position it so that you can view it without having to
twist your body.
Note:
If your monitor weighs more than 100 pounds (45.4 Kg), do not
place it on the top of a desktop model computer.
Glare and lighting
Position the monitor to minimize glare and reflections from overhead lights,
windows, and other light sources. Place the monitor at right angles to
windows and other light sources whenever possible. Reduce overhead
lighting, if necessary, by turning off lights or using lower wattage bulbs. If
you install the monitor near a window, use curtains or blinds to block the
sunlight. You might have to adjust the Brightness and Contrast controls on
the monitor as the room lighting changes throughout the day.
Where it is impossible to avoid reflections or to adjust the lighting, place an
antiglare filter over the screen. However, these filters might affect the
clarity of the image on the screen; try them only after you have exhausted
other methods of reducing glare.
