User Manual BDL4681XU
Service:
• The casing cover should be opened only by qualified service personnel.
• If there is any need for any document for repair or integration, please contact with your local service center.
• Do not leave your monitor in a car/trunk under direct sun light.
Read and follow these instructions when connecting and using your computer monitor:
Consult a service technician if the monitor does not operate normally, or you are not sure what procedure
to take when the operating instructions given in this manual have been followed.
• Unplug the monitor if you are not going to use it for an extensive period of time.
• Unplug the monitor 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 monitor 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 monitor out of direct sunlight and away from stoves or any other heat source.
• Remove any object that could fall into the vents or prevent proper cooling of the monitor’s
electronics.
• Do not block the ventilation holes on the cabinet.
• Keep the monitor dry. To avoid electric shock, do not expose it to rain or excessive moisture.
• If turning off the monitor by detaching power cable or DC power cord, wait for 6 seconds
before attach 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 monitor to rain or
excessive moisture.
• When positioning the monitor, 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 symptom cannot be repaired and is not covered under warranty.
