NOTE: 700 volts can degrade a product. Preventing Electrostatic Damage to Equipment Many electronic components are sensitive to ESD.
Grounding the Work Area To prevent static damage at the work area, use the following precautions: ● Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to the work surface and properly grounded tools and equipment. ● Use static-dissipative mats, foot straps, or air ionizers to give added protection. ● Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate. Handle them only at static-free work areas.
Operating Guidelines To prevent overheating and to help prolong the life of the computer: ● 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. ● Never restrict the airflow into the computer by blocking any vents or air intakes.
To clean the computer case, follow the procedures described below: ● To remove light stains or dirt, use plain water with a clean, lint-free cloth or swab. ● For stronger stains, use a mild dishwashing liquid diluted with water. Rinse well by wiping it with a cloth or swab dampened with clear water. ● For stubborn stains, use isopropyl (rubbing) alcohol. No rinsing is needed as the alcohol will evaporate quickly and not leave a residue.
Cleaning the Mouse Before cleaning the mouse, ensure that the power to the computer is turned off. ● Clean the mouse ball by first removing the retaining plate and the ball from the housing. Pull out any debris from the ball socket and wipe the ball with a clean, dry cloth before reassembly. ● To clean the mouse body, follow the procedures in Cleaning the Computer Case on page 23.
Hard Drives Handle hard drives as delicate, precision components, avoiding all physical shock and vibration. This applies to failed drives as well as replacement spares. ● If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective packaging and label the package “Fragile: Handle With Care.” ● Do not remove hard drives from the shipping package for storage. Keep hard drives in their protective packaging until they are actually mounted in the CPU.
