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.

Safety Precautions
ł
Use only a power source and connection compatible with this monitor, as indicated on the label/
back plate of the monitor.
ł
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.
ł
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.
ł
Do not allow anything to rest on the power cord. Do not walk on the cord.
17
Maintenance Guidelines
To enhance the performance and extend the life of the monitor:
ł
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.
ł
Use only a power source and connection appropriate for this monitor, as indicated on the label/
back plate of the monitor.
ł
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.
ł
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.
ł
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.
ł
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.
ł
Do not drop the monitor or place it on an unstable surface.
ł
Do not allow anything to rest on the power cord. Do not walk on the cord.
ł
Keep the monitor in a well-ventilated area, away from excessive light, heat or moisture.
ł
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.

Power Cord Set Requirements
The monitor power supply is provided with Automatic Line Switching (ALS). This feature allows the
monitor to operate on input voltages between 100–120V or 200–240V.
The power cord set (flexible cord or wall plug) received with the monitor meets the requirements for use
in the country where you purchased the equipment.
If you need to obtain a power cord for a different country, you should purchase a power cord that is
approved for use in that country.
The power cord must be rated for the product and for the voltage and current marked on the product's
electrical ratings label. The voltage and current rating of the cord should be greater than the voltage and
current rating marked on the product. In addition, the cross-sectional area of the wire must be a minimum
of 0.75 mm² or 18 AWG, and the length of the cord must be between 6 feet (1.8 m) and 12 feet (3.6 m).
If you have questions about the type of power cord to use, contact an authorized HP service provider.
A power cord should be routed so that it is not likely to be walked on or pinched by items placed upon
it or against it. Particular attention should be paid to the plug, electrical outlet, and the point where the
cord exits from the product.
