Care and Maintenance 

Care 

z

Avoid exposing your monitor directly to sunlight or other heat source. 
Place your monitor away from the sun to reduce glare. 

z

Put your monitor in a well ventilated area. Do not place anything heavy 

 

on top of your monitor. 

z

Make certain your monitor is installed in a clean and moisture-free area. 

z

Keep your monitor away from magnets, motors, transformers, speakers, 
and TV sets. 

Note:

1. Move the LCD out of the package and take off the plastic bag and 

Polystyrene Foam.

2. Pull the base from Parellel versus Panel to Vertical.
3. Adjust the Panel within 0 degree leaning forward and 25 degree leaning

backward. You must bend harder to exceed 25 degree backward but this
range is for packing the unit to a small size for storage only. Caution: 
Panel exceeding 0 to +25 degree could cause the unit unstable and the
harm will be unpredictable.

Safety Tips: 

z

If smoke, abnormal noise or odor came out of your monitor, switch off 
the power immediately and call your service center. 

z

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.

z

Never try to repair your monitor yourself. Always call your service center 
or a qualified technician to fix it.

Troubleshooting 

No power 

z

Make sure A/C power is securely connected to the power adapter and the 
power supply is firmly connected to the monitor.

z

Plug another electrical device into the power inlet to verify that the outlet 
is supplying proper voltage.

z

Make sure all cables are installed. 

Power on but no screen image 

z

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.

z

Adjust brightness.
