Grounding the Work Area To prevent sta tic damage at the work area, us e the following precautions : ● Cover the work surface with appr oved static-dissipa tive material. Provide a wrist strap connected to the work surface and properly grou nded tools and equ ipment.
Operating Guidelines To prevent ov erheating and to help p rolong the life of the computer: ● Keep the computer away from excessive mo isture , dire ct sunlight, and extremes of heat a nd cold. ● Operate the computer on a sturdy, level surfac e. Leave a 10.
To clean the co mputer case, follow th e procedures described below: ● To remove light sta ins or dirt, use plain water with a clean, lint-free cloth or swab. ● For stronger stains, use a mild dishwashing liq uid diluted with water. Rinse we ll by wiping it with a cloth or swab dampen ed with clear water.
Cleaning the Mouse Before cleanin g the mouse, ensure that the power to the compu ter is turned off. ● Clean the mouse ball by first removing the retaining plate and the ball from the ho using. Pull out any debris from th e ball socket and wipe the ball with a clean, dry cloth befo re reassembly.
