Maintaining Your Display

To maintain your display and ensure its long life:

Â Do not press on the surface of the display screen.

Â Do not write on the screen or touch the screen with a sharp object.

Â If you will not be using your computer for a day or more, turn off the computer and,

if the display has a power button, turn off the display. You can also use Energy Saver.

Cleaning Your Apple Mouse

You may need to clean your mouse from time to time to remove dirt and dust that has

accumulated in the scroll ball area. Hold the mouse upside-down and roll the scroll ball

vigorously using a clean, soft, lint-free cloth to help dislodge any particles that may

interfere with proper scrolling.

Understanding Ergonomics

Here are some tips for setting up a healthy work environment.

Keyboard

When you use the keyboard, your shoulders should be relaxed. Your upper arm and

forearm should form an approximate right angle, with your wrist and hand in roughly a

straight line.

Change hand positions often to avoid fatigue. Some computer users might develop

discomfort in their hands, wrists, or arms after intensive work without breaks. If you

begin to develop chronic pain or discomfort in your hands, wrists, or arms, consult a

qualified health specialist.
