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 
Power Cord Set Requirements on page 43 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 into a grounded (earthed) electrical 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
ENWW Important Safety Information 3
 
						

							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.
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.
CAUTION:Do not use cleaners that contain any petroleum based materials such as benzene, thinner,
or any volatile substance to clean the monitor screen or cabinet. These chemicals may damage the
monitor.
Shipping the Monitor
Keep the original packing box in a storage area. You may need it later if you move or ship the monitor.

							3 Setting Up the Monitor
To set up the monitor, ensure that the power is turned off to the monitor, computer system, and other
attached devices, then follow the instructions below.
Installing the Monitor on the Stand
CAUTION:Do not touch the surface of the LCD panel. Pressure on the panel may cause non-
uniformity of color or disorientation of the liquid crystals. If this occurs the screen will not recover to its
normal condition.
1.Place the monitor panel face down on a dry, soft cloth and connect the VGA cable and power cable
to the monitor.

							2.Place the stand on a desktop or table and push the neck on the stand down to its lowest position.
Slide the monitor all the way onto the stand so that the Quick Release mounting device emits an
audible click and is locked in place.
Figure 3-2  Installing the Monitor on the Stand
3.Route the monitor VGA and power cables through the cable guides at the bottom corners of the
mounting panel (select models).

4.To install an HP USDT computer on the rear of the stand, follow the procedure in Installing an HP
Ultra-slim Desktop (USDT) on the Stand on page 7. To install an HP Thin Client computer on
the rear of the stand, follow the procedure in 
Installing an HP Thin Client on the Stand
on page 11.

							Installing an HP Ultra-slim Desktop (USDT) on the Stand
You can install an HP USDT or Thin Client computer on the rear side of the stand. This section provides
instructions on installing the USDT.
1.On the rear of the stand, remove the two screws (1) from the top of the computer mounting bracket
and lift the bracket off the stand (2).

							2.Use the four screws provided to install the computer mounting bracket on the USDT computer.
NOTE:There are two sets of screw holes on the computer mounting bracket. Use the four holes
that are offset to install the USDT.
Be sure to install the computer mounting bracket on the USDT so that the rear ports on the USDT
are toward the right when viewed from the rear of the monitor stand. (The rear ports should be
toward the left when viewed from the front of the monitor.)
