Maintenance guidelines
To enhance the performance and extend the life of the display:
Do not open the display cabinet or attempt to service this product yourself. Adjust only those
controls that are covered in the operating instructions. If the display 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 display, as indicated on the label/
back plate of the display.
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 display near an outlet that you can easily reach. Disconnect the display by grasping
the plug firmly and pulling it from the outlet. Never disconnect the display by pulling the cord.
Turn the display off when not in use. You can substantially increase the life expectancy of the
display by using a screen saver program and turning off the display when not in use.
CAUTION:
[Author note:]Delete this Caution?
Burn-in damage might occur on displays that display the same static image on the screen for a
prolonged period of time (12 consecutive hours of non-use). To avoid burn-in image damage on
the display screen, you should always activate a screen saver application or turn off the display
when it is not in use for a prolonged period of time or cycle between 5 minutes of static
information and 10 seconds of a moving image. Image retention is a condition that might occur
on all LCD screens. Screen burn-in is not covered under the HP warranty.
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 display 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 display in a well-ventilated area, away from excessive light, heat or moisture.
When removing the display base, you must lay the display face down on a soft area to prevent it
from getting scratched, defaced, or broken.
