Hardware Installation- 5 -

English

Expansion cards contain very delicate Integrated Circuit (IC) chips. To

protect them against damage from static electricity, you should follow

some precautions whenever you work on your computer.

1. Turn off your computer and unplug power supply.

2. Use a grounded wrist strap before handling computer components. If you do not

have one, touch both of your hands to a safely grounded object or to a metal object,

such as the power supply case.

3. Place components on a grounded antistatic pad or on the bag that came with the

components whenever the components are separated from the system.

The card contains sensitive electric components, which can be easily damaged by

static electricity, so the card should be left in its original packing until it is installed.

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 point as the anti-

static mat.

Inspect the card carton for obvious damage. Shipping and handling may cause damage

to your card. Be sure there are no shipping and handling damages on the card before

proceeding.

DO NOT APPLY POWER TO YOUR SYSTEM IF IT HAS BEEN DAMAGED ON

THE CARD.

In order to ensure your graphics card working correctly, please use official

Gigabyte BIOS only. Use none official Gigabyte BIOS might cause problem

on the graphics card.
