How to Mount and Attach Options to the LCD Monitor
You can attach mounting accessories to the LCD monitor in one of the following two ways:
1. In the upright position
3. Ventilation Requirements for enclosure mounting
To allow heat to disperse, leave space between surrounding objects as shown in the diagram below.
2. Lay the screen face down
Lay the protective sheet on a table, which was wrapped around the monitor when it was packaged, beneath the screen surface so as not to scratch the screen face.
This device cannot be used or installed without the Tabletop
Stand or other mounting accessory. Failure to follow correct mounting procedures could result in damage to the equipment or injury to the user or installer. Product warranty does not cover damage caused by improper installation.
Failure to follow these recommendations could result in voiding your warranty.
Use M6 screws (having a length 10 mm longer than the thickness of the mounting bracket) and tighten them securely.
Prevent the screws from loosening using spring washers, etc. MITSUBISHI ELECTRIC recommends using mounting interface that comply with TÜV-GS and/or UL1678 standard in North America.

4. To avoid monitor from falling
When installing the monitor using the tabletop stands (optional), take measures to prevent the monitor from falling over in case of an earthquake or other disaster to lessen the probability of injury and damage resulting from fall.
As shown in the fi gure, secure the monitor to a solid wall or pillar using rope (commercially available) strong enough to bear the weight of the monitor. (MDT421S: approx. 27 kg (with the optional stands))
When you use screw hooks (commercially available), ring screw hooks, not C-shaped screw hooks (with opening), are recommended.

Caution:
For preventing the monitor from falling.
• Install the monitor with metal brackets for wall or ceiling installation (commercially available) on your own responsibility. For detailed procedures of installation, refer to the instructions of the metal brackets.
• To lessen the probability of injury and damage resulting from fall of the monitor in case of earthquake or other disaster, be sure to consult the bracket manufacturer for installation location.
• To lessen the risk of falling of the monitor, thread commercially available rope through the handles at the right and left of the monitor and secure the rope to the wall mount brackets or ceiling mount brackets.
• Do not sleep where the monitor may topple over or fall in case of an earthquake or other disaster.
English-14
Caution:
• The effectiveness of preventing from falling substantially depends on the strength of brackets and base to which prevention device from falling is attached. When you cannot ensure suffi cient strength, provide adequate
reinforcement.
• Though the recommended prevention from falling is intended to lessen the probability of injury and damage, it doesn’t assure its effectiveness against any kind of earthquake or disaster.
• Do not sleep where the monitor may topple over or fall in case of an earthquake or other disaster.
• Before moving the monitor, remove the rope that is securing the monitor. Failure to do so may result in injury or breakdown of the monitor.
Connections
Before making connections:
* First turn off the power of all the attached equipment and make connections.
* Refer to the user manual included with each separate piece of equipment.

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 fi 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
< IMAGE PERSISTENCE >
Please be aware that LCD Technology may experience a phenomenon 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 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 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 a fi xed image is displayed for a 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, the following are recommended.
1. Fixed images should not be displayed for long periods of time, and changed to another images with short cycle.
2. When the monitor is not in use, please turn it off using the remote control, use the Power Management Function or use the
Schedule Function.
3. Reducing the environmental temperature is effective for long life use.
When a Protection board (glass, acrylic) is installed over the LCD surface, enclosed into the box / wall, or the monitors are stacked, 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 the
Screen saver Function.
4. Please use “Screen Saver Mode” of monitor.
< 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 29) is set, the “SCHEDULE” function is disabled.
