Safety and Maintenance
Guidelines
Important Safety Information
A power cord is included with your monitor. If another cord is
used, use only a power source and connection appropriate for this
monitor. For information on the correct power cord set to use with
your monitor, refer to the “Power Cord Set Requirements” section
in Appendix C.
ÅWARNING: To reduce the risk of electric shock or damage to your
equipment, do not disable the power cord grounding feature. This
equipment is designed to be connected to a grounded (earthed)
power outlet that is easily accessible to the operator. The grounding
plug is an important safety feature.
ÅWARNING: For your safety, be sure that the power outlet you plug
the power cord into is easily accessible and located as close to the
equipment as possible. When you need to disconnect the power to
the equipment, unplug the power cord from the power outlet by
grasping the plug firmly. Never pull on the cord.
User Guide 2–1

Safety and Maintenance Guidelines
ÄCAUTION: For the protection of your monitor, as well as your
computer, connect all power cords for your computer and its
peripheral devices (such as a monitor, printer, scanner) to some form
of surge protection device such as a power strip or Uninterruptible
Power Supply (UPS). Not all power strips provide surge protection;
the power strips must be specifically labeled as having this ability.
Use a power strip whose manufacturer offers a Damage Replacement
Policy so you can replace your equipment if surge protection fails.
Maintenance Guidelines
To enhance the performance and extend the life of your monitor:
■ Do not open your monitor cabinet or attempt to service this
product yourself. Adjust only those controls that are covered
in the operating instructions. If your monitor is not operating
properly or has been dropped or damaged, contact your HP
authorized dealer, reseller, or service provider.
■ Use only a power source and connection appropriate for this
monitor, as indicated on the label/back plate of the monitor.
■ Be sure the total ampere rating of the products connected to
the outlet does not exceed the current rating of the electrical
outlet, and the total ampere rating of the products connected
to the cord does not exceed the rating of the cord. Look on the
power label to determine the ampere rating (AMPS or A) for
each device.
■ Install your monitor near an outlet that you can easily reach.
Disconnect the monitor by grasping the plug firmly and
pulling it from the outlet. Never disconnect the monitor by
pulling the cord.
■ Turn your monitor off when not in use. You can substantially
increase the life expectancy of your monitor by using a screen
saver program and turning off the monitor when not in use.
