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. When using with other mounting accessory, the screws must be M6 of size and 10mm or longer of length under consideration of the thickness of the mounting method. (Recommended torque: 470 - 635N•cm). MITSUBISHI ELECTRIC recommends using mounting interface that comply with TÜV-GS and/or UL1678 standard in North America.

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.

• Do not sleep where the monitor may topple over or fall in case of an earthquake or other disaster.

3. Ventilation Requirements for enclosure mounting

To allow heat to disperse, leave space between surrounding objects as shown in the diagram below.

4. To avoid monitor from falling

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. (LDT421V: approx. 27.4 kg) When you use screw hooks (commercially available), ring screw hooks, not C-shaped screw hooks (with opening), are recommended.

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

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.

Selecting a video source

To view a video source:

Use the input button to set [VIDEO]. Use the COLOR SYSTEM menu to set [AUTO], [NTSC], [PAL], [SECAM], [PAL60], [4.43NTSC], according to your video format.

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 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 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.

Provides innovative power-saving methods that allow the monitor to shift to a lower power consumption level when on but not in use, saving two-thirds of your monitor energy costs, reducing emissions and lowering the air conditioning costs of the workplace.

Multiple Frequency Technology:

Automatically adjusts monitor to the display card’s scanning frequency, thus displaying the resolution required.

FullScan Capability:

Allows you to use the entire screen area in most resolutions, signiﬁ cantly expanding image size.

Wall Mounting Interface:

Allows for the monitor to be mounted on a wall or an arm using any third party compliant device. MITSUBISHI ELECTRIC recommends using mounting interface that comply with TÜV-GS and/or UL1678 standard in North America.

TILING, Frame compensation:

Demonstrates multiple screens with an accurate image and compensates for the bezel width.

ZOOM:

Expands the image individually for horizontal and vertical direction.

Self-diagnosis:

When an internal error should occur, a failure state will be indicated.

Troubleshooting

No picture

• The signal cable should be completely connected to the display card/computer.

• The display card should be completely seated in its slot.

• Front Power Switch and computer power switch should be in the ON position.

• Check to make sure that a supported mode has been selected on the display card or system being used. (Please consult display card or system manual to change graphics mode.)

• Check the monitor and your display card with respect to compatibility and recommended settings.

• Check the signal cable connector for bent or pushed-in pins.

Power Button does not respond

• Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor.

Image persistence

• Please be aware that LCD Technology may experience a phenomenon known as Image Persistence. Image Persistence occurs when a 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.

NOTE:

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.

Image is unstable, unfocused or swimming is apparent

• Signal cable should be completely attached to the computer.

• Use the OSD Image Adjust controls to focus and adjust display by increasing or decreasing the ﬁ ne adjustment. When the display mode is changed, the OSD Image Adjust settings may need to be re-adjusted.

• Check the monitor and your display card with respect to compatibility and recommended signal timings.

• If your text is garbled, change the video mode to non-interlace and use 60 Hz refresh rate.

Image of component signal is greenish

• Check to see if the DVD/HD input connector is selected.

LED on monitor is not lit (no green or red color can be seen)

• Power Switch should be in the ON position and power cord should be connected.

• Make certain the computer is not in a power-saving mode (touch the keyboard or mouse).

RED LED on monitor is blinking

• A certain failure might have occurred, please contact your nearest authorized MITSUBISHI ELECTRIC service facility.

Display image is not sized properly

• Use the OSD Image Adjust controls to increase or decrease the coarse adjustment.

• Check to make sure that a supported mode has been selected on the display card or system being used. (Please consult display card or system manual to change graphics mode.)

Selected resolution is not displayed properly

• Use OSD Display Mode to enter Information menu and conﬁ rm that the appropriate resolution has been selected. If not, select corresponding option.

English-36

No Sound

• Check to see if speaker cable is properly connected.

• Check to see if mute is activated.

• Check to see if volume is set at minimum.

Remote Control is not available

• Check the Remote Control’s batteries status.

• Check if batteries are inserted correctly.

• Check if the Remote Control is pointing at the monitor’s remote sensor.

“SCHEDULE”/“OFF TIMER” function is not working properly

• The “SCHEDULE” function will be disabled when the “OFF TIMER” is set.

• If the “OFF TIMER” function is enable and the power to the LCD monitor is turned off if the power supply is interrupted unexpectedly, then the “OFF TIMER” will be reset.

Stripe Noise

Either light vertical or horizontal stripes may appear, depending on the speciﬁ c display pattern. This is no product fault or degradation.
