Moving and lifting the  
Monitor
When moving or lifting the monitor, follow these 
instructions to prevent the monitor from being 
scratched or damaged and to ensure safe trans-
portation, regardless of its shape or size.
 yPlace the monitor in the original box or pack-
ing material before attempting to move it.
 yBefore moving or lifting the monitor, discon-
nect the power cord and all other cables.
 yHold the bottom and side of the monitor frame 
firmly. Do not hold the panel itself.
 yWhen holding the monitor, the screen should 
face toward you to prevent it from being 
scratched.
 yWhen transporting the monitor, do not expose 
the monitor to shock or excessive vibration.
 yWhen moving the monitor, keep it upright and 
never turn the monitor on its side or tilt it side-
ways.
  
y Avoid touching the monitor screen as much as 
possible. 
 
- This may result in damage to the screen or 
some of the pixels used to create images.
 
y If you use the monitor panel without the stand 
base, its joystick button may cause the moni
-
tor to become unstable and fall, resulting in 
damage to the monitor or human injury. In 
addition, this may cause the joystick button to 
malfunction.
