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 qualied 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.
