Adding Memory

In the future you may want to install memory modules to expand the functionality of your computer. You can increase memory to 192 MB by installing an optional memory module. The PCG-Z505R has 64 MB on- board memory; the PCG-Z505RX has 64 MB on-board memory and a 64 MB memory module for a total of 128 MB.

You can add an expansion memory module in a slot. If you have purchased the PCG-Z505R, you can add a 64 MB or 128 MB memory module. If you have purchased the PCG-Z505RX, you can add a 128 MB memory module; this requires removing the supplied 64 MB memory module.*

!Make sure you observe the proper safety precautions when you install a memory module in your computer. See the bulleted list below. Be careful when adding memory. Mistakes when installing or removing a memory module may cause a malfunction.

❑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.

❑Disconnect the system from its power source and from any telecommunications links, networks, or modems before you open the system or follow any of the procedures described below. Failure to do so may result in personal injury or equipment damage.

❑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.

*When you expand the PCG-Z505RX memory to 192 MB, the supplied 64 MB memory module can no longer be used in the PCG-Z505RX.
