Care and Cleaning
Do not place anything on top of the monitor. Doing so may block the monitor vents
and cause damage to the monitor due to overheating.
Do not let liquid get on or into the monitor.
To maximize screen life and prevent damage to the picture tube (such as burned
phosphor due to leaving the same image on the screen for a long time), it is recom-
mended that you:
• Use the monitor power management system (on HP computers) or a screen saver
program.
• Avoid setting contrast and brightness to their maximum levels for prolonged
periods.
• If you do not have a power management system or a screen saver program, switch
the monitor off or reduce the brightness and contrast to minimum levels when the
monitor is not in use.
Your monitor has an anti-glare, anti-static screen coating. To prevent damage to the
monitor screen’s coating, use a regular household glass cleaner when cleaning the
screen. To clean the screen:
1 Switch the monitor off and remove the power plug (pull the plug, not the cable).
2 Wet a soft cotton cloth with the cleaning solution and gently wipe the screen. Do
not spray cleaner onto the screen because the cleaner may drip inside the monitor.
3 Dry with a clean, soft cotton cloth. Do not use cleaning solutions containing
fluoride, acids, or alkalis.
Environmental Information
HP has a strong commitment toward the environment. Your HP monitor has been
designed to respect the environment as much as possible.
HP can also take back your old monitor for recycling when it reaches the end of its
useful life.
In fact, HP has a product take-back program in several countries. The collected
equipment is sent to one of HP’s recycling facilities in Europe or the USA. As many
parts as possible are reused. The remainder is recycled. Special care is taken for
batteries and other potentially toxic substances, which are reduced to non-harmful
components through a special chemical process. If you require more details about
HP’s product take-back program, contact your dealer or your nearest HP Sales Office.
The cathode ray tube used in this monitor does not contain cadmium.
