Caring for Your Computer

This section provides information on how to safely use your Sony computer.

Applying Ergonomics

Your computer is a portable device and can be used in a variety of environments. Whenever possible, you should apply the

following ergonomic considerations:

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, touch pad, 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 —Tilt the display to find the best viewing angle. Also try adjusting the

brightness setting of the display. Following these suggestions can reduce eye strain and muscle fatigue.

Lighting —Choose a location where windows and lights do not create glare or reflection on the display. Use indirect

lighting to avoid bright spots on the display. You can purchase accessories for your display that help reduce glare.

Proper lighting adds to your comfort and work effectiveness.

Placement of 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.

Storing Your Computer

Do not use or store your computer in a location subject to:

Heat sources, such as radiators or air ducts

Direct sunlight

Excessive dust

Moisture or rain

Mechanical vibration or shock

Strong magnets or speakers that are not magnetically shielded

Ambient temperature higher than 95ºF (35ºC) or less than 40ºF (5ºC)

High humidity

Do not place electronic equipment near your computer. When running, the computer's electromagnetic field may

cause other electronic equipment in close proximity to malfunction.

Provide adequate air circulation to prevent internal heat buildup. Do not place your computer on porous surfaces

such as rugs or blankets, or near materials such as curtains or draperies that may block ventilation. Leave a space

of at least 8 inches (20 cm) behind the back of the computer.

If the computer is brought directly from a cold location to a warm one, moisture may condense inside your computer.

In this case, allow at least one hour before turning on your computer. If any problems occur, unplug your computer,

and contact your Sony Service Center.

The computer uses high-frequency radio signals and may interfere with radio or TV reception. Should this occur,

move the computer a suitable distance away from the radio or TV.

Do not drop the computer or place heavy objects on top of the computer.

Using Cables and Connections

Use only specified peripheral equipment and interface cables.

Do not use cut or damaged connection cables.

If the telephone company makes a service call to your home or office and determines that your computer is

responsible for a problem, the telephone company may bill you for the service call. Also, if you do not disconnect

your computer when it is adversely affecting a telephone line, the telephone company has the right to disconnect

your service until you correct the problem.

Cleaning Your Computer

Clean the computer with a soft, dry cloth or a soft cloth lightly moistened with a mild detergent solution. Do not use

any type of abrasive pad, scouring powder, or solvent such as alcohol or benzine, as these may damage the finish

of your computer. You can use canned compressed air specifically for computers to remove dust.

If a solid object falls onto the computer or a liquid leaks into the computer, immediately turn off and unplug the

computer. It is best to have the computer checked by qualified personnel before you use it again.

Avoid rubbing the LCD screen as this can damage the screen. Use a soft, dry cloth to wipe the LCD screen or

canned compressed air.

Always disconnect the power cord before cleaning the computer.

Handling the LCD Screen

Direct sunlight can damage the LCD. Be careful when using the computer near a window.

Do not scratch the LCD or exert pressure on it. This can cause a malfunction.

Using the computer in low temperature conditions may produce a residual image on the screen. This is not a

malfunction. When the computer returns to normal temperature, the screen returns to normal.

The screen becomes warm during operation. This is normal and does not indicate a malfunction.

The LCD is manufactured using high-precision technology. You may, however, see tiny black points and/or bright

points (red, blue, or green) that continuously appear on the LCD. This is a normal result of the manufacturing

process and does not indicate a malfunction.
