● 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: Burn-in or image sticking might occur on displays which display the same static
image on the screen for prolonged periods of time. To avoid burn-in or image sticking and to
prolong the life of the display, you should activate one of the four ISM selections in the OSD,
activate a screen-saver application, periodically cycle between static information and moving
images, or turn off the display when it is not in use for prolonged periods of time.
● 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.
Cleaning the display
1. Turn off the display and unplug the power cord from the back of the unit.
2. Dust the display by wiping the screen and the cabinet with a soft, clean antistatic cloth.
3. For more difficult cleaning situations, use a 50/50 mix of water and Isopropyl alcohol.
CAUTION: Spray the cleaner onto a cloth and use the damp cloth to gently wipe the screen surface.
Never spray the cleaner directly on the screen surface. It might seep behind the bezel and damage
the electronics.
CAUTION: To clean the display screen or cabinet, do not use cleaners that contain any petroleum-
based materials such as benzene or thinner or any volatile substance. These chemicals might
damage the display.
