Read and follow these instructions when connecting and using your Public Information Display:

•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.

•If turning off the display by detaching the power cable, wait for 6 seconds before re-attaching the power cable 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.
