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 "Connecting the Power Cable" section in Setting Up the Monitor  
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.  
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.  
20  
Safety Precautions  
Use only a power source and connection compatible with 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 power  
cord does not exceed the rating of the power cord. Look on the power label to determine the ampere  
rating (Amps or A) for each device.  
Install your monitor near a power 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.  
Do not allow anything to rest on the power cord. Do not walk on the cord.

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.  
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 base, 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 the computer.  
2. Unplug the monitor from the wall outlet.  
3. Clean the monitor plastics with a clean cloth dampened with water.  
4. Clean the monitor screen with an antistatic screen cleaner.  
CAUTION: Do not use benzene, thinner, ammonia, or any other volatile substances to clean the  
monitor or the screen. These chemicals may damage the cabinet finish as well as the screen.  
Shipping the Monitor  
Keep the original packing box in a storage area. You may need it later if you move or ship the monitor.
