Accessibility Information - Lenovo ThinkCentre M900z 10F2 Hardware Maintenance Manual

• Screen position: Keep the screen at a comfortable viewing distance, usually 51-61 cm (20-24 inches).
Then, adjust the screen so that the top of the screen is at or slightly below eye level and you can view it
without twisting your body.
• Chair position: Use a chair that gives you good back support and seat height adjustment. Use chair
adjustments to best suit your desired posture.
• Head position: Keep your head and neck in a comfortable and neutral (vertical or upright) position.
• Arm and hand positions: Keep your forearms, wrists, and hands in a relaxed and neutral (horizontal)
position. Type with a soft touch without pounding the keys.
• Leg position: Keep your thighs parallel to the floor and your feet flat on the floor or on a footrest.
Make minor modifications in your working posture to deter the onset of discomfort caused by long periods of
working in the same position. Frequent, short breaks from your work also help to prevent minor discomfort
associated with your working posture.
