NOTE 1: IMAGE PERSISTENCE
Please be aware that LCD Technology may experience a phenomena known as Image Persistence. Image P\
ersistence occurs 
when residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitors’ 
image persistence is not permanent, but constant images being displayed \
for a long period of time should be avoided.
To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an 
image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase 
the image.
As with all personal display devices, MITSUBISHI ELECTRIC recommends displaying moving images and using a moving 
screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.
Please set “POWER SAVE”, “SCREEN SAVER”, “DATE AND TIME” and “SCHEDULE” functions to further reduce the risk of 
Image persistence.
For long life use of Public Display
< Image Sticking of LCD Panel >
When LCD panel is operated continuously for long hours, a trace of elect\
ric charge remains near the electrode inside LCD, and 
residual or “ghost” image of previous image may be observed. (Image Persistence)
Image Persistence is not permanent, but when fi  xed image is displayed for long period, ionic impurities inside LCD are 
accumulated along the displayed image, and it is observed permanently. (Image Sticking)
< Recommendations >
For preventing the fast transition to Image Sticking, and for longer life usag\
e of LCD, following are recommended.
1.   Fixed image should not be displayed for long period, and changed to anot\
her images with short cycle.
2.   When no use, please turn off the monitor by remote control, or use Power Management Function of monitor or use Schedule  Function of monitor.
3.   Reducing the environmental temperature is effective for long life use.
  When Protection board (glass, acryl) is installed over the LCD surface, enclosed into the \
box / wall, or stack the monitor,  please utilize the temperature sensors inside monitor.
  To reduce the environmental temperature, the monitor should be set Low Brightness or Cooling Fan “ON” by\
 using Screen  saver Function.
4.   Please use Screen Saver Mode of monitor.
NOTE 2: HOW TO SETUP SCHEDULE Using the “SCHEDULE” function allows you to set up to seven different scheduled time intervals when the LCD Monitor will 
be activated.
You can select the time the monitor turns on and turns off, the day of week the monitor is activated, and which input source 
the monitor will use for each scheduled activation period. A check mark \
in the box next to the number of the schedule 
indicates that the selected schedule is in effect.
To select which schedule to set, use the up/down arrows to move the number (1 to 7) of the schedule.
Use the (+) and (-) buttons to move the cursor horizontally within t\
he particular schedule. Use the (
) and () buttons to 
increase time and select input port. The “SET” button is used to make \
a selection.
If you create a schedule but do not want to use a power on time, select “--”\
 in the “ON” time slot.
If you do not want to use a power off time select “--” in the OFF time slot.
If there is no input selected (“--” showing in the input spot) the inpu\
t from the previous schedule will be used.
The selection of EVERY DAY within a schedule takes priority over other schedules that are set up to operate weekly.
When schedules are overlapping, scheduled Power ON time has priority over scheduled Power\
 OFF time.
If there are two schedules programmed for the same time, then the highest numbered schedule has priority.
When the “OFF TIMER” (see page 27) is set, the “SCHEDULE” \
function is disabled.
