Protecting the Computer from Damage

Protecting the Computer from Damage

Your computer is a delicate device that requires careful handling. To keep it from being damaged, keep these precautions in mind:

• Do not subject your computer to any physical shock.

• Do not place anything heavy on your computer.

• Do not pour liquid onto your computer.

• Keep the computer at least 13 cm (5 in.) away from any electrical appliance that generates a strong magnetic field such as a motor, magnet, TV, refrigerator, or large audio speaker.

• Use your computer when temperatures are between 5°C to 35°C (41°F to 95°F), between 10°C to 35°C (50°F to 95°F) when operating with diskettes.

• Do not disassemble the computer.

• Do not scratch, twist, hit, or push the surface of the LCD.

• Remove the battery pack and keep it in a cool place if you will not be using the computer for a long period of time.

• Insert a diskette straight into the diskette drive. Inserting it at an angle can damage the front of the diskette drive.

• Do not place more than one diskette label on a diskette. Two or more labels can cause a label to tear apart inside the drive and damage the diskette drive.

Occasionally clean your computer as follows:

• Use a soft cloth moistened with nonalkaline detergent to wipe the exterior of the computer.

• Gently wipe the LCD with a dry, soft cloth. Do not use alcohol or detergent.

Carrying the Computer

When carrying your computer, follow these instructions to prevent possible damage to your computer and data:

1. Turn off all attached devices.

2. Turn off the computer and close the LCD.

3. Unplug all external cables and cords connected to the computer.

4. Make sure all covers on the computer are closed.
