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.
