Using Power Management
The LCD monitor follows the VESA approved DPM Power
Management function.
The power management function is an energy saving
function that automatically reduces the power consumption
of the display when the keyboard or the mouse has not been
used for a xed period.
The power management feature on your new display has
been set to the “ON” mode. This allows your display to enter
a Power Saving Mode when no signal is applied. This could
potentially increase the life and decrease the power
consumption of the display.

NOTE 1: IMAGE PERSISTENCE
Please be aware that LCD Technology may experience a phenomena known as Image Persistence. Image Persistence 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 &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 electric 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 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 usage of LCD, following are recommended.
1. Fixed image should not be displayed for long period, and changed to another 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
sever 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 the 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 input 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.

3) Control sequence
(1) The command from a computer to the LCD monitor will be sent in 600 ms.
(2) The LCD monitor will send a return command 600 ms* after it has received and encoded. If the command isn’t received
correctly, the LCD monitor will not send the return command.
(3) The personal computer checks the command and conrms if the command, which has been sent, has been executed or
not.
(4) This LCD monitor sends various codes other than return code. When having a control sequence by RS-232C, reject other
codes from personal computers side.
* : The sending time of return command may delay depending on the condition (during changing of the input signal, etc.).
