Important Safety Warnings
WARNING! Avoid Electrical Shocks. To avoid electrical shock, do not open the power supplies. There
are no user-serviceable parts inside.
To avoid electrical shock and harm to your eyes by laser light, do not open the DVD laser module. The
laser module should be serviced by service personnel only. Do not attempt to make any adjustment to
the laser unit. Refer to the label on the DVD for power requirements and wavelength. This product is a
class I laser product.
WARNING!
Grounding your Equipment.
For your safety always connect the equipment to a grounded
wall outlet. Always use a power cord with a properly grounded plug, such as the one provided with the
equipment, or one in compliance with your national safety standards. This equipment can be
disconnected from the power by removing the power cord from the power outlet. This means the
equipment must be located close to an easily accessible power outlet.
WARNING! Protecting your Ears. If your system is a multimedia model, or if you have installed a sound
card in your system, always turn the volume down before connecting the headphones or speakers. This
prevents discomfort from unexpected noise or static. Listening to loud sounds for prolonged periods of
time may permanently damage your hearing. Before putting on headphones, place them around your
neck and turn the volume down. When you put on the headphones, slowly increase the volume until you
find a comfortable listening level. When you can hear comfortably and clearly, without distortion, leave
the volume in that position.
WARNING!
Removing and Replacing the Cover.
For your safety, never remove the system side cover
without first disconnecting the power cord from the power outlet and removing any connection to a
telecommunications network. If a Power Protection Device is fitted to your system, you must shut down
your computer using its on/off switch, then remove the power cord before removing the system’s side
cover. Remove the Power Protection Device cables before any servicing operation. Always replace the
side cover before switching the system on again.
