• To prevent electrical shock hazard, disconnect the power cable from the
electrical outlet before relocating the system.
• When adding or removing devices to or from the system, ensure that the
power cables for the devices are unplugged before the signal cables are
connected. If possible, disconnect all power cables from the existing system
before you add a device.
• Before connecting or removing signal cables from the motherboard, ensure
that all power cables are unplugged.
• Seek professional assistance before using an adapter or extension cord.
These devices could interrupt the grounding circuit.
• Make sure that your power supply is set to the correct voltage in your area.
If you are not sure about the voltage of the electrical outlet you are using,
contact your local power company.
• If the power supply is broken, do not try to x it by yourself. Contact a
qualied service technician or your retailer.

the power cables are not damaged. If you detect any damage, contact your
dealer immediately.
• To avoid short circuits, keep paper clips, screws, and staples away from
connectors, slots, sockets and circuitry.
• Avoid dust, humidity, and temperature extremes. Do not place the product in
any area where it may become wet.
• Place the product on a stable surface.
• If you encounter technical problems with the product, contact a qualied
service technician or your retailer.
