Safety and Maintenance Guidelines

Important Safety Information

The power cord is designed for use with your monitor. To use a different cord, use only a power source and

connection compatible with this monitor.

WARNING:

Always connect your monitor, the computer, and other equipment to a grounded (earthed) power

outlet. To reduce the risk of electric shock or damage to your equipment, do not diable the power cord grounding
feature. The grounding plug is an important safety feature.

WARNING:

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.

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:

A certified power supply cord has to be used with this equipment. The relevant national

installation and/or equipment regulations shall be considered. A certified power supply cord not lighter
than ordinary polyvinyl chloride flexible cord according to IEC 60227 (designation H05VV-F 3G 0.75mm²
or H05VVH2-F2 3G 0.75mm²) shall be used. Alternative a flexible cord be of synthetic rubber.

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 dose 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 your monitor:

Do not open your monitor cabinet or attempt to service this product yourself. If your monitor is not operating

properly or has been dropped or damaged, contact your Hewlett-Packard authorized dealer, reseller, or service
provider.

Adjust only those controls that are described in the operating instructions.

Turn your 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.

Keep your monitor in a well-ventilated area, away from excessive light, heat, or moisture.

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.

Unplug the monitor from the power outlet before cleaning. Do not use liquid cleaners or aerosol cleaners.

Do not drop the monitor or place it on an unstable surface.

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.
