Recommendations
■
Adjust your chair height: your feet should be flat on the floor and the
bottom of your thighs should be evenly supported by the seat. If your
feet cannot reach the floor, use a foot rest. Avoid pressure points
behind the knee or under the thigh.
■
The space under your desk should be free of clutter so that your legs
and feet are not restricted, and you can get close enough to your
product and other items that you use frequently.
■
Adjust the chair back rest: it should match the curve of your back and
provide comfortable back support.
■
Adjust the chair arm rests: they should be about the same height as the
keyboard and comfortably support your arms, allowing your shoulders
to relax.
■
When using the keyboard, it should be centered in front of you.
■
The keyboard and pointing device should be close to your elbow level.
The keyboard should be flat so that your wrists are straight when typing.
However, if the product is on a worksurface that is above your elbow
height you may need to slope the product to keep your wrists straight.
■
Work with relaxed shoulders.
■
When typing, keep your wrists straight and try not to rest your wrists on
the product. Support your arms on your forearm area. The forearms can
be supported by the chair arm supports or the desk surface.
■
The product display should be tilted so that the image on the screen is
clear.
■
Avoid glare: position the product so that light sources (lamps or
windows) do not shine or reflect directly into your eyes. Place the
product display away from bright light sources or reduce the light
intensity from windows by using blinds. Glare on the product display
may cause eye strain, eye fatigue or headaches.
■
Certain product displays have a brightness approaching that of a TV
device. We recommend that you adjust the brightness of your product
display to a comfortable level to prevent possible eye strain.
■
Keep your head level, facing forward and balanced over your torso.
■
Adjust the font size of text on your screen to make viewing comfortable.
