HEALTH WARNING
Use of a keyboard or mouse may be linked to serious injuries or disorders .
When using a computer, as with many ac tivities, you may experience occasional discomfor t in your hands, arms,
shoulder s, neck , or other par ts of your bod y. However, if you exper ience symptoms such as persistent or
recurring discomfort, pain, throbbing, aching, tingling, numbness, burning sensation, or stiffness, DO NOT
IGNORE THESE WARNING SIGNS. PROMPTLY SEE A QUALIFIED HEALTH PROFESS IONAL , even if symptoms
occur when you are not working at your computer. Symptoms like these can be associated with painful and
sometime s permanently disabling injurie s or disorders of the ner ves, muscles, tendons, or other parts of the
body. These musculoskeletal disorders (MSDs) include carpal tunnel syndrome, tendonitis, tenosynovitis, and
other conditions.
While researchers are not yet able to ans wer many ques tions about MSDs, there is general agreement that
many factors may be linked to their occurrence, including: overall health, stress and how one copes with it,
medical and physical conditions, and how a person positions and uses his or her body during work and other
activities (including use of a keyboard or mouse). The amount of time a person performs an activity may also be
a factor.
Some guidelines that may help you work more comfortably with your computer and possibly reduce your risk of
experiencing an MSD can be found in the “Healthy Computing Guide” installed with this device’s software. If
this device did not come with sof tware, see the “Healthy Computing Guide” se ction of the “Getting Started”

For additional guidelines that may help you play more comfortably when you use the gaming features of your
keyboard or mouse, see the “Healthy Gaming Guide” at w ww.xbox.com/suppor t.
If you have questions about how your own lifestyle, activities, or medical or physical condition may be related to
MSDs, see a qualified health professional.
