7 MAINTENANCE AND UPGRADES

Maintenance

Preserving Data

Viruses can corrupt files; files can be inadvertently deleted; and hard-disk drives can fail after extended used. To avoid data loss, regularly back up the data files on the hard-disk drive. If you lose the contents of your hard-disk drive, you can reinstall programs, but your data files will be lost if you don’t have a backup. We recommend you back up the hard-disk drive at least once a week, with a daily backup of those files that have been changed.

External Components

To clean the exterior computer cabinet, perform the following steps:

1.Place a grounding strap around your wrist to reduce the effects of electrostatic discharge (ESD).

2.Turn off the computer and any attached devices.

3.Use a small vacuum cleaner to remove any dust from the slots and holes on the computer.

4.Moisten a soft cleaning cloth with water and liquid dishwashing detergent.

DO NOT SOAK the cloth in the solution—you must not let the solution drip inside the computer.

5.Use the damp cloth to wipe the computer housing.

Touchscreen/Display

To ensure the longevity and effectiveness of the touchscreen please take note of the following precautions:

•Do not press sharp objects against the screen.

•Do not strike the panel with hard objects.

•Do not press the screen with excessive force.

•Once the panel is mounted and has power applied, do not place any objects over the ventilation slots. This will result in heat buildup and may damage the unit.
