wrists, arms, shoulders, neck, or

back, and can include:

work with the hands is being performed,

including during the night when these

symptoms might awaken you. If you

experience these symptoms, or any other

persistent or recurring pain or discomfort

that you think may be related to using a

computer, you should promptly consult a

qualified physician and, if available, your

company’s health and safety department.The

earlier a problem is properly diagnosed and

treated, the less chance there is that it will

progress to a disabling condition.

workstation setup, posture, and health and

work habits for computer users. In addition,

this Guide contains product safety informa-

tion applicable to all Compaq products.

setup, incorrect work habits, stressful work

conditions and relationships, or problems in

your personal health may be linked to

injuries.These injuries could include carpal

tunnel syndrome, tendinitis, tenosynovitis,

and other musculoskeletal disorders.

IMPORTANT

Some scientists believe that working intensely,

or for a long time in uncomfortable or unnatural

positions, may pose risks, such as those

mentioned in the Warning.

The information

included in this Guide is designed to help you

work more safely by recommending ways to

work more comfortably and effectively.

TIP

Self-check

After reviewing the information in this chapter,

double-check your postures and habits using

Chapter 6, "Self-Check."

Posture, lighting, furniture, work

organization, and other work conditions

and habits may affect the way you feel and

how well you work.By adjusting your work

environment and personal practices, you

may be able to minimize fatigue and

discomfort, and reduce the risk of

resulting strains that some scientists

believe can lead to injury.

Important Choices

Whenever you use a computer, you make

choices that can affect your comfort and

potentially your safety.This is true

whether you use a full-size keyboard and

monitor on a desk,a notebook computer,or

a wireless keyboard on your lap. In every

case,you choose your working posture and

your body’s position relative to your

keyboard,pointing device,monitor, remote

control, phone, and any reference books

and papers.You may also have some control

over lighting and other factors.

Take Action for Safety

and Comfort

Many factors in our work environment

determine whether we work efficiently and

in a manner that promotes good health and

safety. By considering, acting on, and

periodically reevaluating the recommenda-

tions in this Guide, it is possible to create a

safer, more comfortable,healthful, and

efficient work environment.
