Sony PCG-Z505LS User Guide

VAIO® Z505 SuperSlim Pro™ Notebook User Guide

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

❑

Position of your computer — Place the computer directly in front of you as 
you work. Keep your forearms horizontal, with your wrists in a neutral, 
comfortable position while using the keyboard, touchpad, or external mouse. 
Let your upper arms hang naturally at your sides. Take 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 and 
armrests. 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 backward.

❑

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 also.
