Important Warnings
Avoid Electrical Shocks
WARNING To avoid electrical shock, do not open the power supply. There are no
user-serviceable parts inside.
To avoid electrical shock and harm to your eyes by laser light, do not open the
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 CD-ROM for power requirements and wavelength. This product is a class I
laser product.
Electrical
WARNING 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.
Multimedia Models
WARNING 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.
Removing And Replacing The Cover
WARNING You can remove system covers to remove or replace hot-swappable devices,
such as hard disk drives, optical drives and fans. However, when removing
components other than hot-swappable devices, never remove the system cover
without first disconnecting the power cord from the power outlet and
removing any connection to a telecommunications network. Always replace
the cover before switching the system on again.
