SAVE THESE INSTRUCTIONS Additional Safety Information This product has not been evaluated for connection to an "IT" power system (an AC distribution system with no direct connection to earth, according to IEC 60950). AC Power Safety Warning WARNING: Install the computer near an AC outlet. The AC power cord is your HP Pavilion's main AC disconnecting device and must be easily accessible at all times. For your safety, the power cord provided with your system has a grounded plug. Always use the power cord with a properly grounded wall outlet, to avoid the risk of electrical shock. WARNING: Your system is provided with a voltage select switch for use in a 115 or 230 VAC power system. The voltage select switch has been pre-set to the correct voltage setting for use in the particular country/region where it was initially sold. Changing the voltage select switch to the incorrect position can damage your PC and void any implied warranty. WARNING: To reduce the possibility of an electric shock from the telephone network, plug your computer into the AC outlet before connecting it to the telephone line. Also, disconnect the telephone line before unplugging your computer from the AC power outlet. WARNING: Always disconnect the modem cord from the telephone system before installing or removing your computer cover. WARNING: Do not operate the computer with the cover removed. WARNING: The power supply is not userserviceable. To prevent damage to the power supply, have a qualified person repair or replace it. All other components are user-serviceable. WARNING: Electrostatic discharge (ESD) can damage disk drives, add-in cards, and other components. If an ESD station is not available, wear a wrist strap attached to a metal part of the computer. Place cards on a conductive foam pad or inside the card wrapper, if possible, but never on the card wrapper. WARNING: For your safety, always unplug the system from its power source and from any telecommunications systems (such as phone lines), networks, or modems before performing any of the procedures described in this guide. Failure to do so may result in personal injury or equipment damage. Hazardous voltage levels are inside the power supply and modem of this product. Lithium Battery Caution WARNING: The PC uses a lithium battery, type CR2032. There is danger of an explosion if the battery is incorrectly replaced.
