Care and Maintenance

Care
Avoid exposing your monitor directly to sunlight or other heat source. Place your
monitor away from the sun to reduce glare.
Put your monitor in a well ventilated area.
Do not place any heavy things on top of your monitor.
Make certain your monitor is installed in a clean and moisture-free area.
Keep your monitor away from magnets, motors, transformers, speakers, and TV
sets.
Note
Move the LCD out of the package and take off the plastic bag and Polystyrene Foam.
Pull the base from Parallel versus Panel to Vertical.
Adjust the Panel within 0 degree leaning forward and 20 degree leaning
backward. You must bend harder to exceed 20 degree backward but this range
is for packing the unit to a small size for storage only.
Safety Tips:
If smoke, abnormal noise or odor came out from your monitor, caution you
should remove the power cord immediately and call your service center.
Never remove the rear cover of your monitor cabinet. The display unit inside
contains high-voltage parts and may cause electric shock to human bodies.
Never try to repair your monitor yourself. Always call your service center or a
qualified technician to fix it.

Troubleshooting

No power
Make sure A/C power cord is securely connected to the power adapter and the
power supply is firmly connected to the monitor.
Plug another electrical device into the power outlet to verify that the outlet is
supplying proper voltage.
Make sure all signal cables are installed.
Power on but no screen image
Make sure the video cable supplied with the monitor is tightly secured to the
video output port on back of the computer. If not, tightly secure it.
Adjust brightness.
