•  Unplug the display if you are not going to use it for an extensive period of time.
•  Unplug the display if you need to clean it with a slightly damp cloth. The screen many be wiped with a dry cloth when the power is

off. However, never use alcohol, solvents or ammonia-based liquids.

•  Consult a service technician if the display does not operate normally when you have followed the instructions in this manual.
•  The casing cover should be opened only by qualified service personnel.
•  Keep the display out of direct sunlight and away from stoves or any other heat sources.
•  Remove any object that could fall into the vents or prevent proper cooling of the display’s electronics.
•  Do not block the ventilation holes on the cabinet.
•  Keep the display dry. To avoid electric shock, do not expose it to rain or excessive moisture.
•  When turning off the display by detaching the power cable or DC power cord, wait for 6 seconds before re-attaching the power

cable or DC power cord for normal operation..

•  To avoid the risk of shock or permanent damage to the set do not expose the display to rain or excessive moisture.
•  When positioning the display, make sure the power plug and outlet are easily accessible.
•  IMPORTANT: Always activate a screen saver program during your application. If a still image in high contrast remains on the

screen for an extended period of time, it may leave an ‘after-image’ or ‘ghost image’ on the front of the screen. This is a well-known

phenomenon that is caused by the shortcomings inherent in LCD technology. In most cases the afterimage will disappear gradually

over a period of time after the power has been switched off. Be aware that the after-image symptom cannot be repaired and is not

covered under warranty.
