Safety and Maintenance Guidelines 
 
Important Safety Information 
The power adapter and cord are designed for use with your HP monitor . The adapter provided by HP is only for this   
monitor. To use a different cord, use a power source and connection compatible with this adapter. For information on 
the correct power cord set to use with your monitor, see Power Cord Set Requirements
. 
 
WARNING: To reduce the risk of electric shock or damage to your equipment, do not disable the power cord 
grounding feature. The grounding plug is an important safety feature. Connect the equipment to a grounded 
(earthed) power outlet. 
For your safety, be sure that the grounded power outlet you plug the power cord into is easily accessible to 
the operator and located as close to the equipment as possible. To disconnect power from the equipment, 
unplug the power cord from the power outlet by grasping the plug firmly. Never pull on the cord. 
Before connecting cables, disconnect power from the monitor by unplugging the power cord from the 
electrical outlet. 
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 its 
plug. 
To Avoid electrical shock, do not open the monitor cover or the power adapter. There are no user serviceable 
parts inside. Only qualified service personal should service these parts. 
 
 
 
CAUTION: To protect your monitor, as well as your computer, connect all power cords for your computer and 
its peripheral devices (such as a monitor, printer, or scanner) to a surge protection device such as a power 
strip with surge protection 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 your 
equipment if surge protection fails. 
 
 
 
CAUTION: Avoid applying pressure to the LCD screen; doing so can cause damage. 
Safety Precautions  
y Use the monitor with the power adapter supplied with your HP monitor only. 
y 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. 
y Install your 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. 
y 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 your monitor:

properly or has been dropped or damaged, contact your HP authorized dealer, reseller, or service provider. 
y Adjust only those controls that are described in the operating instructions. 
y Turn your monitor off when not in use. You can substantially increase the life expectancy of your monitor by using a 
screen saver and turning off the monitor when not in use. 
y Keep your monitor in a well-ventilated area, away from excessive light, heat, or moisture. 
y 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. 
y Unplug your monitor from the wall outlet before cleaning.
