EFORE YOU START
Thank you for choosing our product. Before you start installing the
motherboard, please make sure you follow the instructions below:
Prepare a dry and stable working environment with
sufficient lighting.
Always disconnect the computer from power outlet
before operation.
Before you take the motherboard out from anti-static
bag, ground yourself properly by touching any safely
grounded appliance, or use grounded wrist strap to
remove the static 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 flex the board.
Do not leave any unfastened small parts inside the
case after installation. 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.
