A Safety and Maintenance Guidelines
Important Safety Information
A power cord is included with the 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 the
monitor, refer to the “Power Cord Set Requirements” section in Agency Regulatory Notices.
Warning! To reduce the risk of electric shock or damage to the equipment:
Do not disable the power cord grounding feature. The grounding plug is an important
safety feature.
Plug the power cord into an easily accessible grounded outlet.
Disconnect the power from the equipment by unplugging the power cord from the electrical
outlet.
For your safety, do not place anything on power cords or cables. Arrange them so that no one may
accidentally step on or trip over them. Do not pull on a cord or cable. When unplugging from the
electrical outlet, grasp the cord by the plug.
To reduce the risk of serious injury, read the Safety and 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
documentation disc, if one is included with the monitor.
CAUTION: For the protection of the monitor, as well as the computer, connect all power cords for the
computer and its peripheral devices (such as a monitor, printer and 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 the equipment, if
surge protection fails.
Use the appropriate and correctly sized furniture designed to properly support your HP LCD monitor.
WARNING! LCD monitors that are inappropriately situated on dressers, bookcases, shelves, desks,
speakers, chests, or carts may fall over and cause personal injury.
Care should be taken to route all cords and cables connected to the LCD monitor so that they can not be
pulled, grabbed, or tripped over.
