HARDWARE INSTALLATION

Handling the PCI Sound Card

WARNING: Static electricity can damage your equipment. Do not take the card out of its static protective bag until you are ready to work with it.

Follow these precautions when handling the card:

• Before you open the static protective bag, touch it to a metal expansion slot cover on the back of your computer. This drains static electricity from the package and from your body.
• Do not touch any exposed printed circuitry after opening the package.
• Keep other people from touching the card. They might have a static-electricity build-up.
• Limit your movement. Movement causes a build-up of static electricity.

Installing the PCI Sound Card

1. Turn off the system and all peripheral devices.
2. Disconnect the power cord and all peripheral devices from the system.
3. Remove the system cover and identify an unused PCI slot.
4. Unscrew the slot cover plate, plug in the PCI Sound Card, and tighten it with the screw.
5. If you have speakers or amplifiers, plug the cable into the J1 or J2 Jack on the back of the Sound Card.
6. Depending on what type of CD Audio cable you have connect J10 or J11 on the Sound Card and the Audio output at the back of the CD-ROM drive. Make sure pin 1 of J10 or J11 is connected to the leftmost pin of the CD-ROM Audio output.
7. Put back the system cover, reconnect the system power cord and all peripheral devices. Check and make sure all connections are correct before you turn on the system.

NOTE: If you want to listen to the sound of DOS Games and your motherboard supplies the respective connector, please connect the cable for the PC PCI Legacy Audio Sideband Signal to J16 on the PCI Sound Card.
