Important notes about your Plasma TV

The following symptoms are not signs of malfunction but technical limitation. Therefore TACP/TCL disclaims any responsibility for these symptoms.

1)Plasma display radiates infrared rays. It may affect other infrared communication equipment under certain operating condition.

2)Plasma display may cause interference in image, sound, etc. of other electronic equipment that is easy to receive electromagnetic waves (i.e. AM radios and video equipment) under certain installed condition. In particular, it may affect electronic equipment beyond the residential unit where a plasma display TV is used.

3)The Plasma display panel is manufactured using an extremely high level of precision technology, however sometimes some parts of the screen may be missing picture elements or have luminous spots.

4)You can enjoy a video game with this TV. However, the game which uses a ray gun etc. and makes a screen a target has some which cannot be used on a principle.

5)Like all phosphor-based display devices and all gas plasma display, plasma display can be susceptible to permanent ghost image (phosphor burn-in) under certain circumstances. Certain operating conditions, such as the continuous display of a static image (i.e. logos, video games, computer images, teletext) and displaying images in 4:3 mode over a prolonged period of time, accelerate phosphor burn-in if proper precautions are not taken.

To minimize the occurrence of phosphor burn-in, adhere to the following guidelines and recommendations:

¥Display a moving image whenever possible.

¥Always power down the display when you are finished using it.

6)Even though you follow the above recommendations, phosphor burn-in can still occur since phosphors deteriorate as usage time accumulates. To reduce and delay the phosphor burn-in take the following measures:

¥Lower the Brightness and Contrast levels as much as possible without impairing image readability.

¥The LONG LIFE settings can reduce phosphor burn-in. (page 60.)

¥Display an image with many colors and color gradations (i.e. photographic or photo-realistic images).

¥Create image content with minimal contrast between light and dark areas, for example, avoid white characters on black backgrounds. Use complementary or pastel color whenever possible.

¥Avoid displaying images with few colors and distinct, sharply defined borders between colors.

About ISM (Image Sticking Minimization) function

The ISM function (The Image Sticking Minimization function) automatically starts to decrease the brightness with small steps when fixed pattern displays for long time. The pace of the decrease and the delay time depend on the brightness in the displayed screen.
