User Manual BDL4230ET
Service:
• The casing cover should be opened only by qualified service personnel.
• If there is any need for repair or integration, please contact your local service center.
• Do not leave your display under direct sunlight.
Read and follow these instructions when connecting and using your display:
If your display does not operate normally, having followed the instructions set out in this document, please
contact a technician or your local service center.
• 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 may 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 after having 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 the 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 symptoms cannot be repaired and are not covered under warranty.
