Adjust the tilt of the monitor, its contrast and brightness settings, and the lighting

around you (such as overhead lights, desk lamps, and the curtains or blinds on

nearby windows) to minimize reflections and glare on the monitor screen.

²

Use a chair that provides good lower back support.

²

Keep your forearms horizontal with your wrists in a neutral, comfortable position

while using the keyboard or mouse.

²

Always leave space to rest your hands while using the keyboard or mouse.

²

Let your upper arms hang naturally at your sides.

²

Sit erect, with your feet resting on the floor and your thighs level.

²

When sitting, make sure the weight of your legs is on your feet and not on the

front of your chair seat. Adjust your chair±s height or use a footrest, if necessary,

to maintain proper posture.

²

Vary your work activities. Try to organize your work so that you do not have to

type for extended periods of time. When you stop typing, try to do things that

use both hands.

1.

Touch

an unpainted metal surface on the chassis, such as the metal around the

card-slot openings at the back of the computer, before touching anything inside

your computer.

While you work, periodically touch an unpainted metal surface on the computer

chassis to dissipate any static electricity that might harm internal components.

2.

Turn off your computer and any peripherals.

3.

Disconnect

your computer and peripherals from their power sources. Also, dis-

connect any telephone or telecommunication lines from the

computer.

Doing so reduces the potential for personal injury or shock.
