							2 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 on page 32 in Appendix C.
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 in a grounded (earthed) outlet that is easily accessible at all times.
• Disconnect power from the product 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 
http://www.hp.com/ergo and/or on
the documentation CD, 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, 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.

							Maintenance Guidelines
To enhance the performance and extend the life of the monitor:
●Do not open the monitor cabinet or attempt to service this product yourself. Adjust only those
controls that are covered in the operating instructions. If the monitor is not operating properly or
has been dropped or damaged, contact an authorized HP 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 the 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 the monitor off when not in use. You can substantially increase the life expectancy of the
monitor by using a screen saver program and turning off the monitor when not in use.
NOTE:Monitors with a “burned-in image” are not covered under the HP warranty.
●Slots and openings in the cabinet are provided for ventilation. These openings must not be blocked
or covered. Never push objects of any kind into cabinet slots or other openings.
●Do not drop the monitor or place it on an unstable surface.
●Do not allow anything to rest on the power cord. Do not walk on the cord.
●Keep the monitor in a well-ventilated area, away from excessive light, heat or moisture.
●When removing the monitor stand, you must lay the monitor face down on a soft area to prevent
it from getting scratched, defaced, or broken.
Cleaning the Monitor
1.Turn off the monitor and unplug the power cord from the back of the unit.
2.Dust the monitor by wiping the screen and the cabinet with a soft, clean antistatic cloth.
3.For more difficult cleaning situations, use a 50/50 mix of water and Isopropyl alcohol.
CAUTION:Spray the cleaner onto a cloth and use the damp cloth to gently wipe the screen surface.
Never spray the cleaner directly on the screen surface. It may run behind the bezel and damage the
electronics.

Downloading from the Worldwide Web on page 12 in this chapter.
The Information File
The .INF file defines monitor resources used by Microsoft Windows operating systems to ensure monitor
compatibility with the computer’s graphics adapter.
This monitor is Microsoft Windows Plug and Play compatible and the monitor will work correctly without
installing the .INF file. Monitor Plug and Play compatibility requires that the computer’s graphic card is
VESA DDC2–compliant and that the monitor connects directly to the graphics card. Plug and Play does
not work through separate BNC type connectors or through distribution buffers/boxes.
The Image Color Matching File
The .ICM files are data files that are used in conjunction with graphics programs to provide consistent
color matching from monitor screen to printer, or from scanner to monitor screen. This file is activated
from within graphics programs that support this feature.
NOTE:The ICM color profile is written in accordance with the International Color Consortium (ICC)
Profile Format specification.
