● Keep work area free of non-conductive materials such as ordinary plastic assembly aids and Styrofoam.
● Use eld service tools, such as cutters, screwdrivers, and vacuums, that are conductive.
Recommended materials and equipment
HP recommends the following grounding equipment to prevent electrostatic damage:
● Antistatic tape
● Antistatic smocks, aprons, or sleeve protectors
● Conductive bins and other assembly or soldering aids
● Conductive foam
● Conductive tabletop workstations with ground cords of 1 MΩ ±10% resistance
● Static-dissipative table or oor mats with hard ties to ground
● Field service kits
● Static awareness labels
● Wrist straps and footwear straps providing 1 MΩ ±10% resistance
● Material handling packages
● Conductive plastic bags
● Conductive plastic tubes
● Conductive tote boxes
● Opaque shielding bags
● Transparent metallized shielding bags
● Transparent shielding tubes
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 airow.
● Never restrict the airow into the computer by blocking any vents or air intakes. Do not place the keyboard,
with the keyboard feet down, directly against the front of the desktop unit as this also restricts airow.
● Occasionally clean the air vents on all vented sides of the computer. Lint, dust, and other foreign matter can
block the vents and limit the airow. Be sure to unplug the computer before cleaning the air vents.
● Never operate the computer with the cover or side panel removed.
● Do not stack computers on top of each other or place computers so near each other that they are subject
to each other’s recirculated or preheated air.
● If the computer is to be operated within a separate enclosure, intake and exhaust ventilation must be
provided on the enclosure, and the same operating guidelines listed above will still apply.
● Keep liquids away from the computer and keyboard.
