Important:
When the equipment is unattended, make sure to play video or
display image in a loop. No video played or image displayed for a
long time may cause "incidental image" on the screen, also known
as "residual image" or "after-image".
This is a common phenomenon in liquid crystal panel technology.
In most cases, after turning off the power supply for a certain
period of time, the "incidental image", "residual image" and "after-
image" will gradually disappear.
Warning:
Serious "incidental image", "residual image" or "after-image" will
not disappear and cannot be recovered. This is also not covered
by the warranty.
Maintenance:
• Only professional maintenance personnel can open the casing
cover.
• For maintenance or integration, please contact your local service
center.
