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

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.

Power Cord Set Requirements on page 70.

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
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.

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.
