Precautions and Procedures

The procedures described below assume familiarity with the general terminology associated with personal computers and with the safety practices and regulatory compliance required for using and modifying electronic equipment. Personal injury or equipment damage may result from failure to take these precautions.

Sony recommends memory upgrades be performed by an authorized Sony Service Center. To find the nearest center or agent, see http://www.sony.com/pcsupport.

Observe the proper safety precautions when installing memory modules in your computer. See the bulleted list below. Use care when adding memory. Mistakes when installing or removing a memory module may cause a malfunction.

❑Disconnect the system from its power source and from any telecommunications links, networks, or modems before you open the system.

❑Electrostatic discharge (ESD) can damage disk drives and other components. Perform the procedures described below only at an ESD workstation. If such a station is not available, do not work in a carpeted area, and do not handle materials that produce or hold static electricity (cellophane wrappers, for example). Ground yourself by maintaining contact with an unpainted metal portion of the chassis while performing the procedure.

❑Do not open the memory module package until you are ready to install the module. The package protects the module from ESD.

❑Use the special bag for preventing ESD or use aluminum foil when you store the memory module.
