CAUTION: This system must be operated with the system cover installed to ensure proper
cooling.

that are shipped with your product.
To avoid injury to yourself or damage to the system, follow these guidelines:
• Always disconnect the system from the power outlet whenever you are working inside the system.
• If possible, wear a grounded wrist strap as you work inside the system. Or discharge any static
electricity by touching the bare metal chassis of system case, or the bare metal body of any other
grounded appliance.
• Hold electronic circuit boards by the edges only. Do not touch the components on the board unless it
is necessary to do so. Do not flex or stress the circuit board.
