Important Safety Warnings
WARNING! Avoiding Electrical Shocks. 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 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.
WARNING! Getting Battery Safety Information. There is a danger of explosion if the battery is incorrectly
installed. For your safety, never attempt to recharge, disassemble, or burn an old battery. Replace the
battery with the same or equivalent type, as recommended by the manufacturer.
The battery in this system is a lithium battery that does not contain any heavy metals. However, to protect
the environment, do not dispose of batteries in household waste. Return used batteries either to the shop
from which you bought them, to the dealer from whom you purchased your system, or to HP so that they
can either be recycled or disposed of in the correct way. Returned batteries will be accepted free of
charge.
