Safety precautions and maintenance
WARNING: Use of controls, adjustments or procedures other than those
specified in this documentation may result in exposure to shock, electrical
hazards and/or mechanical hazards.
Read and follow these instructions when connecting and using your computer monitor:
● 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 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 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 after-
image 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.
