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 95.

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.
• 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.

For details on using the HP Network Sign Manager application, refer to the HP Network Sign Manager User Guide (available only in English) included on the CD provided with the display.

Connecting daisy chain displays

Multiple displays (up to 25) can be connected in a daisy chain (connect several displays together in Tile Mode) to a computer using DisplayPort IN/OUT or with the combination of RGB IN/OUT and RS-232-C IN/OUT ports on the display.

To connect displays in a daisy chain, the displays must all be connected with the same input/output source (DisplayPort IN/OUT, RS-232-C IN/OUT, or RGB IN/OUT) as shown in the figures below.

• To daisy chain displays for video, use DisplayPort IN/OUT connections or RGB IN/OUT connections.
• To daisy chain for both video and display command and control, use DisplayPort IN/OUT plus RS-232-C IN/OUT or RGB IN/OUT plus RS-232-C IN/OUT.

NOTE: The number of displays that can be connected by daisy chain to one media player/computer might vary depending on the signal status and cable loss. If the signal status is good, and there is no cable loss, it is possible to connect up to twenty-five displays in a daisy chain from one media player/computer.

If you are going to play video that is copy protected with High-bandwidth Digital Content Protection (HDCP), a maximum of six displays can be daisy chained.

To connect multiple displays in a daisy chain, connect the input signal cable from the media player/computer to the first display in the daisy chain. Connect the subsequent displays, using the same input signal cables, from the OUT port to the IN port of the next display, as shown in the figures below, until all the displays are connected together.
