Precaution

On Safety

  • Operate the unit only with a power source as specified in the “Specifications” section.
  • A nameplate indicating operating voltage, etc., is located on the rear panel.
  • Should any solid object or liquid fall into the cabinet, unplug the unit and have it checked by qualified personnel before operating it any further.
  • Do not drop or place heavy objects on the power cord. If the power cord is damaged, turn off the power immediately. It is dangerous to use the unit with a damaged power cord.
  • Unplug the unit from the wall outlet if it is not to be used for several days or more.
  • Disconnect the power cord from the AC outlet by grasping the plug, not by pulling the cord.
  • The socket-outlet shall be installed near the equipment and shall be easily accessible.

On Installation

  • The LCD panel can be used in portrait or landscape orientation. Make the appropriate settings for display orientation on your computer.
  • Prevent internal heat build-up by allowing adequate air circulation. Do not place the unit on surfaces (rugs, blankets, etc.) or near materials (curtains, draperies) that may block the ventilation holes.
  • Do not install the unit near heat sources such as radiators or air ducts, or in a place subject to direct sunlight, excessive dust, mechanical vibration or shock.
  • Do not place the unit near equipment which generates magnetism, such as a transformer or high voltage power lines.

About the LCD Panel

- The LCD panel fitted to this unit is manufactured with high precision technology, giving a functioning pixel ratio of at least 99.99%. Thus a very small proportion of pixels may be “stuck”, either always off (black), always on or flashing. In addition, over a long period of use, because of the physical characteristics of the liquid crystal display, such “stuck” pixels may appear spontaneously. This is not a malfunction.

  • Do not leave the LCD screen facing the sun as it can damage the LCD screen. Take care when you place the unit by a window.
  • Do not push or scratch the LCD screen. Do not place a heavy object on the LCD screen. This may cause the screen to lose uniformity.
  • If the unit is used in a cold place, a residual image may appear on the screen. This is not a malfunction. When the unit becomes warm, the screen returns to normal.
  • The screen and the cabinet become warm during operation. This is not a malfunction.

Even if it is used properly, the unit may cause harmful interference to radio or television reception. Try the following measures to correct it.

  • Increase the distance between the unit and the radio/TV.
  • Connect the unit to a different outlet from the one to which the radio/TV is connected.

Protective Filter

The LCD panel comes with an anti-reflection-coated protective filter. The surface is very delicate. Do not rub or hit with hard objects.

On Burn-in

Permanent burn-in may occur if still images are displayed in the same position on the LCD panel continuously, or repeatedly over extended periods.

Images that may cause burn-in

  • Images that remain static for a long time
  • Character or message displays that indicate settings or operating state

To reduce the risk of burn-in

  • Turn on the screensaver function Turn on the screensaver or enable the standby mode to avoid permanent burn-in of an image displayed for an extended period on the LCD panel.
  • Turn off the power when not in use Turn off the power if the unit is not to be used for an extended period of time.

On Long Periods of Use

Due to the characteristics of the LCD panel, displaying static images for extended periods, or using the unit repeatedly in high temperature/high humidity environments may cause image smearing, burn-in, areas of which brightness is permanently changed, lines, or a decrease in overall brightness.

In particular, continued display of an image smaller than the screen, such as in a different aspect ratio, may shorten the life of the unit.

Avoid displaying a still image for an extended period, or using the unit repeatedly in a high temperature/high humidity environment such as airtight room, or around the outlet of an air conditioner.

To prevent any of the above issues, we recommend turning off the power whenever the unit is not in use.

On Cleaning

  • When cleaning the unit, remove the AC power cord from the unit and the wall outlet for your safety.
  • Wipe off dust on the unit surface with a soft cloth. Dampen it lightly in mild soap solution to wipe off grease.
  • Do not spray insecticides and other volatile solutions on the unit surface. Do not keep rubber or vinyl in contact with the cabinet for a long time. It could damage the unit surface and/or the coating could come off.
  • The unit is made of plastic and coated metal plate. Never use solvents such as benzene or thinner, or acid, alkaline or abrasive detergent, or a chemical cleaning cloth for cleaning or disinfection, as they may damage the unit surface.
  • Be careful when handling the LCD panel (protective filter). The surface is very delicate. Do not rub or hit with hard objects.

Disposal of the Unit

  • Do not dispose of the unit with general waste. Do not include the unit with household waste.
  • The fluorescent tube includes mercury. Dispose of the unit in accordance with the regulations of your local sanitation authority.

Recommendation to Use More Than One Unit

As problems can occasionally occur with the unit, if it is used for safety control of personnel, assets or stable picture, or for emergencies, we strongly recommend you use more than one unit, or have a spare unit available.

On Repacking

Do not throw away the carton and packing materials. They make an ideal container by which to transport the unit.

If you have any questions about this unit, contact your authorized Sony dealer.

On Moisture Condensation

If the unit is brought directly from a cold place to a warm place, or the unit is warm and the ambient temperature cools suddenly (by air-conditioning, for example), moisture may condense on the surface or inside of the unit.

This is called moisture condensation, and is not a malfunction of the product itself, although it may cause damage to the unit.

Leave the unit in a condensation free area. If moisture condensation has occurred, turn off the unit and do not use it until moisture condensation has evaporated.

Having the Unit Periodically Cleaned

If the unit is not cleaned for long periods, dust accumulation inside the unit may cause fire or electric shock.

Have an authorized Sony dealer clean the unit's interior at least once a year.

About the Power On/Off

Leave an interval of at least 10 seconds between turning the unit on/off.
