Wireless LAN

The wireless LAN option allows easy connection to large or small office networks while also providing freedom from the constraints of cables and sockets.

Memory Modules

You can increase system memory by installing optional memory modules. You can install a 128, 256 or 512 MB module.

To avoid possible system problems, use only approved memory modules in your computer. Please consult the appropriate sections of this manual, Samsung Technical Support, or the support website (www.samsungpc.com) for additional information.

Before You Install Memory

To prevent personal injury and damage to the equipment, follow the precautions listed here before installing a memory module.

Take the following precautions when installing a memory module:

Before you start this process, turn off the computer, unplug the power cord, and remove the battery. Also, disconnect any external devices.

Before handling a memory module, discharge any static electricity by touching a grounded surface or using a grounding wrist strap.

Do not insert objects with conductive material, such as metal screwdrivers or graphite pencils, into the memory-module compartment.

Be careful in handling the metal plate of the memory door.
