Safety and Maintenance

Guidelines

Important Safety Information

A power cord is included with your 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

your monitor, refer to the “Power Cord Set Requirements” section

in Appendix C.

Å

WARNING: To reduce the risk of electric shock or damage to your

equipment, do not disable the power cord grounding feature. This

equipment is designed to be connected to a grounded (earthed)

power outlet that is easily accessible to the operator. The grounding

plug is an important safety feature.

Å

WARNING: For your safety, be sure that the power outlet you plug

the power cord into is easily accessible and located as close to the

equipment as possible. When you need to disconnect the power to

the equipment, unplug the power cord from the power outlet by

grasping the plug firmly. Never pull on the cord.

User Guide 2–1

Safety and Maintenance Guidelines

Ä

CAUTION: For the protection of your monitor, as well as your

computer, connect all power cords for your 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 your equipment if surge protection fails.

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. Adjust only those controls that are covered

in the operating instructions. If your monitor is not operating

properly or has been dropped or damaged, contact your HP

authorized 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 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.

■ Turn your monitor off when not in use. You can substantially

increase the life expectancy of your monitor by using a screen

saver program and turning off the monitor when not in use.

on the cord.

■ Keep your monitor in a well-ventilated area, away from

excessive light, heat or moisture.
