Adding Memory

In the future you may want to install memory modules to expand the 
functionality of your computer. You can increase memory to 256 MB by 
installing an optional memory module.

❑

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.
