Ergonomic considerations

You will be using your notebook as a portable device in a variety of environments. Whenever possible, you should attempt to take account of the following ergonomic considerations to both stationary and portable environments.

❑ Position of your computer – Place the computer directly in front of you (1). Keep your forearms

horizontal (2), with your wrists in a neutral, comfortable position (3) while using the keyboard, touchpad, or external mouse. Let your upper arms hang naturally at your sides. Have breaks during sessions with your computer. Excessive use of the computer may strain muscles or tendons.

❑ Furniture and posture – Sit in a chair with good back support. Adjust the level of the chair so your feet

are flat on the floor. A footrest may make you more comfortable. Sit in a relaxed, upright posture and avoid slouching forward or leaning far backwards.

Welcome

Sony Notebook User Guide

❑ Viewing angle of the computer’s display – Use the display’s tilting feature to find the best position.

You can reduce eye strain and muscle fatigue by adjusting the tilt of the display to the proper position. Adjust the brightness setting of the display as well.

❑ Lighting – Choose a location where windows and lights do not create glare and reflection on the

display. Use indirect lighting to avoid bright spots on the display. You can also purchase accessories for your display that help reduce glare. Proper lighting adds to your comfort and work effectiveness.

❑ Positioning an external display – When using an external display, set the display at a comfortable

viewing distance. Make sure the display screen is at eye level or slightly lower when you are sitting in front of the monitor.
