1�1 Before You Start
Thank you for choosing our product. Before you start installing the motherboard, please make
sure you follow the instrucons below:
• Prepare a dry and stable working environment with sucient lighng.
• Always disconnect the computer from power outlet before operaon.
• Before you take the motherboard out from an-stac bag, ground yourself properly
by touching any safely grounded appliance, or use grounded wrist strap to remove the
stac charge.
• Avoid touching the components on motherboard or the rear side of the board unless
necessary. Hold the board on the edge, do not try to bend or ex the board.
• Do not leave any unfastened small parts inside the case aer installaon. Loose parts
will cause short circuits which may damage the equipment.
• Keep the computer from dangerous area, such as heat source, humid air and water.
• The operang temperatures of the computer should be 0 to 45 degrees Celsius.
• To avoid injury, be careful of:
Sharp pins on headers and connectors
Rough edges and sharp corners on the chassis
Damage to wires that could cause a short circuit
