Ergonomic Considerations

fatigue by adjusting the tilt of the display to the proper position. Adjust the 
brightness setting of the display also.

❑

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.

❑

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.

❑

Do not place 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 of more than 95º F (35º C) or less than 40º F 
(5º C)

❑

High humidity

❑

Do not place electronic equipment near your computer. The computer’s 
electromagnetic field may cause a 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 its ventilation slots. 
Leave a space of at least 8 inches (20 cm) behind the back panel 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 an 
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 cause interference 
to radio or TV reception. Should this occur, relocate the computer a suitable 
distance away from the set.
