Safety Information

Before you get started, please read this important
safety information about your HP Pavilion
home PC.

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 Warnings

The power supply is pre-set for the country/region in which
you purchased the HP Pavilion. If you move to another
country/region, please make sure you check its voltage
requirements before plugging your PC into an AC power
outlet.

Install the computer near an AC outlet. The AC power cord
is your HP Pavilion PC’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.

To reduce the possibility of an electric shock from the
telephone network, always plug your computer into the AC
outlet before connecting it to the telephone line. Also,
always disconnect the telephone line before unplugging
your computer from the AC power outlet. Failure to do so
before you open the PC or do any procedures can result in
personal injury, or equipment damage.

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.

Always disconnect the modem cord from the telephone
system before installing or removing your computer cover.

Do not operate the computer with the cover removed.
The power supply is not user-serviceable. To prevent

damage to the power supply, have a qualified person repair
or replace it. All other components are user-serviceable.

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.

The PC is heavy; be sure to use ergonomically correct lifting
procedures when moving the computer.
