How to Place and Install your System at its Best

It is important that you place your computer taking into account ergonomic and security
issues.
Here you can find some hints to make your working environment safer, handier, and more
pleasant.
Your Monitor. Place your monitor at 50-60 cm from the operator's eyes, and in a position so
that the upper part of its frame is at the same level of the operator's eyes. These precautions
will prevent eyes and neck strain. To further reduce eyes strain, it is recommended that
sometimes you close your eyes, focusing other objects, located at different distances from
your computer screen. To improve this precaution's effectiveness, repeat it twice per hour.
Some monitors have a removable, pivoted base. You can turn and adjust it according to your
posture, to place your monitor in the most convenient way.
Your Chair. If you are planning of using your computer for a long period of time, choose a
special chair, designed for office work, that you can adjust according to your ergonomic
needs. Seat, back, height, angle, and inclination of your chair have to be adjustable.
To prevent strain, you have to support your lumbar region. Only adjustable chairs allow you
to adjust the chair to your specific body size. Your chair's arm should fit your elbows level,
and your shoulders posture and size. You should use them as a support. To improve your
comfort, change your body position frequently. When you sit, you should adopt a comfortable
position, and keep your head straight. Your shoulders should be relaxed: do not lean towards
your desk.
Anti-glare Treatments. Some screens come with an anti-glare treatment to reduce eyes
strain.
Lighting. If the lighting is too poor or too intense, working at your computer may become
difficult. Try to find the best compromise, avoiding to face powerful light sources, or to work
in dim lighting conditions. Using adjustable lamps and diffuse lighting, helps you to find the
best working conditions, and to reduce eyes strain.
Your Hands and your Wrists. When typing on your keyboard, keep your wrists straight,
and your forearms parallel to the floor. If you use a wrist holder, use it only for a short period
of time.
When working at your computer for a long period of time, take frequent breaks, and do some
stretching exercise.
