Warranty Information
The model and serial number are on the rear panel. Retain this book and your purchase receipt for warranty service.
Setup: Ask a qualified technician to set up the LCD display. Keep small parts away from children to prevent choking hazards. Ensure the display is placed on a stable surface and not over the edge of the base. Do not place objects on top of the display. Transport the unit in an upright position. Ensure ventilation openings are not blocked. Maintain adequate space around the display for heat release. If used outdoors in temperatures below 32°F (0°C), set "Outdoor mode" to "On".
Installation: Wall installation should be performed by a professional. Use a VESA-compliant wall bracket. Ensure the terminal cover is placed downward when installing vertically. Install away from heaters.
Using the LCD Display: Ensure the terminal cover is firmly attached. Do not insert foreign objects. Do not remove the cover or modify the unit. Ensure the mains plug is easily accessible. Use only the provided power supply cord and insert it fully. Do not handle the plug with wet hands. Protect the power cable from damage. Unplug the unit when not in use for prolonged periods or during lightning storms.
Cleaning and Maintenance: Disconnect all cables before moving. Unplug the power supply before cleaning. Clean the power cable regularly. Do not burn or breakup batteries. Clean the glass surface gently with a soft, lint-free cloth, using pure water or a diluted neutral detergent if necessary. Wipe the cabinet with a soft, dry cloth, or a damp cloth with diluted neutral detergent if it is particularly dirty. Avoid volatile substances.
Maintaining Air Filters: Unplug the power plug before removing air filters. Loosen decorative screws, remove the filter cover, and pull out the air filter. Clean air filters by soaking in a diluted neutral detergent, rinsing, and drying. Replace damaged or soiled filters. Clean filters every 3 months and replace annually.

Troubleshooting and error codes
| Picture | Sound | Symptoms | Checks |
|---|---|---|---|
| Interference | Noisy Sound | Electrical Appliances, Cars / Motorcycles, Fluorescent light | None |
| Normal Picture | No Sound | Volume (Check whether the mute function has been activated on the remote control.) | None |
| ? | No Sound | Normal Picture | Not plugged into AC outlet, Not switched on, Picture and Brightness/Volume setting (Check by pressing the power switch or stand-by button on the remote control.) |
| ? | No Picture | Normal Sound | If a signal with a non-applicable colour system format, or frequency is input, only the input terminal indication is displayed. |
| No remote control operations can be performed. | Check whether the batteries have discharged completely and, if they have not, whether they were inserted properly. Check whether the remote control sensor is exposed to an outdoor light or a strong fluorescent light. Check whether the remote control designed specifically for use with the unit is being used. (The unit cannot be operated by any other remote control.) | ||
| A cracking sound is sometimes heard from the unit. | If there is nothing wrong with the picture or sound, this is the sound of the cabinet undergoing very slight contractions in response to changes in the room temperature. There are no adverse effects on the performance or other aspects. | ||
| The top or bottom of the picture on the screen is cut off when I use the zoom function. | Adjust the position of the picture on the screen. | ||
| Areas at the top and bottom of the screen where the image is missing appear when I use the zoom function. | When using a video software program (such as a cinema size program) with a screen wider than one in the 16:9 mode, blank areas separate from the images are formed at the top and bottom of the screen. | ||
| I can hear sounds coming from inside the unit. | When the power is turned on, a sound of the fan may be heard: This is normal and not indicative of malfunctioning. | ||
| Parts of the unit become hot. | Even when the temperature of parts of the front, top and rear panels has risen, these temperature rises will not pose any problems in terms of performance or quality. | ||
| Power automatically turns off unexpectedly. | Check the settings of "No signal power off", "PC Power management", "DVI-D Power management" and "No activity power off". Any of them may be set to "On (Enable)". (see page 33, 34) | ||
| There is no picture displayed or sound output sometimes. | When HDMI or DVI signals are input to the Display using a selector or distributor, sound or images may not be output in the normal fashion depending on the selector or distributor used. The symptoms may be improved by turning the power off and on again, or by replacing the selector or distributor. | ||
| The RS232C is uncontrollable | Check whether the connection has been made properly. (see page 14) When controlling the RS232C command on page 14 from the RS232C terminal in the display, make sure that "Control I/F Select" is "RS-232C (Serial)", and that it is "RS-232C(DIGITAL LINK)" when controlling from the RS232C terminal of the DIGITAL LINK device. (see page 43) | ||
| The LAN is uncontrollable | Check whether "LAN Setup" has been configured properly. (see page 44) (When controlling from the RS232C terminal of the DIGITAL LINK device) Check whether the connection has been made properly. (see page 49) Check whether "Control I/F Select" is "LAN" when controlling with the WEB browser control or the command control on page 51. (see page 43) Check whether "LAN Setup" has been configured properly. (see page 44) | ||
| There is no picture displayed or sound output from the DIGITAL LINK terminal. | When connecting to a device of AMX, Crestron Electronics, Inc., or Extron, set "AMX D.D.", "Crestron Connected™™", or "Extron XTP" according to the device to use. (see page 43) See the "Signal quality” information of "DIGITAL LINK status" to check the LAN cable status such as whether the LAN cable is disconnected or the cable is not shielded. (see page 45) | ||
| This LCD Display uses special image processing. Hence a slight time lag may occur between image and audio, depending on the type of input signal. However, this is not a malfunction. | Check whether the connection has been made properly between the video (output) equipment and twisted pair cable transmitter and between the twisted pair cable transmitter and this product. (see page 15) Check whether "DIGITAL LINK mode" is set to "Auto" or "DIGITAL LINK" instead of "Ethernet". (see page 43) | ||
