Information

Although this unit incorporates high precision technology in its design, please understand that there may be extremely slight pixel breakup, or light emission fault.

Note

In order to protect this unit’s panels and circuitry, the revolving speed of the interval fan will be automatically increased in order to cool the inside of the unit when the surrounding temperature exceeds 40 °C. (The sound of the fan will become louder at this time). Please operate this unit in a location with a surrounding temperature under 40 °C.

About the plasma panel’s protection function

The brightness of this display will deteriorate slightly when an image with little movement such as a photograph or computer image is continuously displayed. This is caused by the plasma panel’s protection function which detects images with slight movement and automatically adjusts brightness to protect the display, and is not a malfunction.

This function starts approximately 5 minutes after the power has been turned on or after input has been

switched.

2The surrounding temperature has risen above 40 °C.

Please operate this unit in a location with a surrounding temperature under 40 °C.

3The vents are blocked or the internal temperature has risen abnormally due to abnormal heat generation of internal parts etc..

If the power is automatically turned off for a reason other than the above reasons, there could be a malfunction. In this case, unplug the power cord from the power outlet and request repair from your nearest sales outlet.

•The plasma display panel of this unit is very bright and viewing it a close distance will cause eye strain.
