A Electrostatic Discharge A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive 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: 34 ● 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 to permit the required airflow.
Optical Disc Drive Precautions Be sure to observe the following guidelines while operating or cleaning the optical disc drive. ● Do not move the drive during operation. This may cause it to malfunction during reading. ● Avoid exposing the drive to sudden changes in temperature, as condensation may form inside the unit. If the temperature suddenly changes while the drive is on, wait at least one hour before you turn off the power. If you operate the unit immediately, it may malfunction while reading.
