2 Safety and maintenance guidelines
Important safety information
A power cord is included with the display. If another cord is used, use only a power source and
connection appropriate for this display. For information on the correct power cord set to use with the
display, refer to the Power cord set requirements on page 96.
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 can
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 www.hp.com/ergo
and/or on the documentation CD, if one is included with the display.
CAUTION: For the protection of the display, as well as the media player/computer, connect all
power cords for the media player/computer and its peripheral devices (such as a display, 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.
Use the appropriate and correctly sized furniture designed to properly support your display.
WARNING! Displays that are inappropriately situated on dressers, bookcases, shelves, desks,
speakers, chests, or carts can fall over and cause personal injury.
Care should be taken to route all cords and cables connected to the display so that they cannot be
pulled, grabbed, or tripped over.
CAUTION: Do not place the device in a location where water may drip and/or splash on the device.
Do not place an object that contains water, such as a flower vase, on the device.
Maintenance guidelines
To enhance the performance and extend the life of the display:
●Do not open the display cabinet or attempt to service this product yourself. Adjust only those
controls that are covered in the operating instructions. If the display 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 display, as indicated on the label/
back plate of the display.
ENWW Important safety information 3

●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 display near an outlet that you can easily reach. Disconnect the display by grasping
the plug firmly and pulling it from the outlet. Never disconnect the display by pulling the cord.
●Turn the display off when not in use. You can substantially increase the life expectancy of the
display by using a screen saver program and turning off the display when not in use.
CAUTION: Burn-in or image sticking might occur on displays which display the same static
image on the screen for prolonged periods of time. To avoid burn-in or image sticking and to
prolong the life of the display, you should activate one of the four ISM selections in the OSD,
activate a screen-saver application, periodically cycle between static information and moving
images, or turn off the display when it is not in use for prolonged periods of time.
●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 display 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 display in a well-ventilated area, away from excessive light, heat or moisture.
●When removing the display base, you must lay the display face down on a soft area to prevent it
from getting scratched, defaced, or broken.

Cleaning the display
1. Turn off the display and unplug the power cord from the back of the unit.
2. Dust the display 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 might seep behind the bezel and
damage the electronics.
CAUTION: To clean the display screen or cabinet, do not use cleaners that contain any petroleum-
based materials such as benzene or thinner or any volatile substance. These chemicals might
damage the display.
Shipping the display
Keep the original packing box in a storage area. You might need it later if you move or ship the
display.
