Important safety information
WARNING! To reduce the risk of serious injury, read the Safety & Comfort Guide. It describes
proper workstation setup, posture, and health and work habits for computer users, and provides
important electrical and mechanical safety information. This guide is located on the Web at
http://www.hp.com/ergo and on the Documentation CD that is included with the product.
To reduce the risk of electric shock or damage to the equipment:
● Plug the power cord into an AC outlet that is easily accessible at all times.
● Disconnect power from the computer by unplugging the power cord from the AC outlet.
● If provided with a 3-pin attachment plug on the power cord, plug the cord into a grounded
(earthed) 3-pin outlet. Do not disable the power cord grounding pin, for example, by attaching a
2-pin adapter. The grounding pin is an important safety feature.
The computer may be heavy; be sure to use ergonomically correct lifting procedures when moving it.
Install the computer near an AC outlet. The AC power cord is your computer’s main AC disconnecting
device and must be easily accessible at all times. For your safety, the power cord provided with your
computer 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, 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.
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.
For your safety, always unplug the computer from its power source and from any telecommunications
systems (such as telephone lines), networks, or modems before performing any service procedures.
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.
CAUTION: If your computer is provided with a voltage select switch for use in a 115 or 230 V 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 computer and void any implied warranty.
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/EN 60950).
