Safety Information

Electrical safety

z To prevent electrical shock hazard, disconnect the power cable from the electrical

outlet before relocating the system.

z 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.

z Before connecting or removing signal cables from the motherboard, ensure that all

power cables are unplugged.

z Seek professional assistance before using an adapter or extension cord. These

devices could interrupt the grounding circuit.

z 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.

z If the power supply is broken, do not try to fix it by yourself. Contact a qualified service

technician or your retailer.
