A Electrostatic discharge A discharge of static electricity from a finger or other conductor may damage system boards or other staticsensitive devices. This type of damage may reduce the life expectancy of the device. Preventing electrostatic damage To prevent electrostatic damage, observe the following precautions: ● Avoid hand contact by transporting and storing products in static-safe containers. ● Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
B Computer operating guidelines, routine care and shipping preparation Computer operating guidelines and routine care Follow these guidelines to properly set up and care for the computer and monitor: ● Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold. ● Operate the computer on a sturdy, level surface. Leave a 10.2 cm (4 inch) clearance on all vented sides of the computer and above the monitor to permit the required airflow.
Shipping preparation Follow these suggestions when preparing to ship the computer: 1. Back up the hard drive files to an external storage device. Be sure that the backup media is not exposed to electrical or magnetic impulses while stored or in transit. NOTE: The hard drive locks automatically when the system power is turned off. 2. Remove and store all removable media. 3. Turn off the computer and external devices. 4. Disconnect the power cord from the AC outlet, then from the computer. 5.
