Static Electricity Precaution

Static electricity can easily damage your SQ576 mainboard. Observing a few basic

precautions can help you safeguard against damage that could result in expensive repairs.

Follow the simple measures below to protect your equipment from static electricity damage:

Keep the mainboard and other system components in their anti-static packaging until you are

ready to install them.

Touch a grounded surface before you remove any system component from its protective anti-

static packaging. Unpacking and installation should be done on a grounded, anti-static mat.

The operator should be wearing an anti-static wristband, grounded at the same points as the

anti-static mat.

After removing the mainboard from its original packing, only place it on a grounded, anti-

static surface component side up. Immediately inspect the board for damage. Due to shifting

during shipping, it is suggested that the installer press down on all of the socket IC‘s to ensure

they are properly seated. Do this only with the board placed on a firm flat surface.

During configuration and installation, touch a grounded surface frequently to discharge any

static electrical charge that may have built up in your body. The best precaution is to wear a

grounded wrist strap. When handling the mainboard or an adapter card avoid touching its

components. Handle the mainboard and adapter cards either by the edges or by the adapter

card’s case mounting bracket.
