Operating Precautions and recommendations

6.1 Operating Precautions and recommendations

1)If the display shuts down on its own and will not power up again, please try the followings. Turn off the main power switch for the plasma display, wait 10 seconds and power it on again.

If the display shuts down, there may be a internal problem, Consult with Pioneer Authorized Service Center. If it remains powered up, you may continue using it.

2)If the same image is shown on the screen for a prolouged period of time (i.e. a still picture or a closed-captioning, etc.), then this image may become permanently burnt onto the screen.

This ploblem can be managed by changing image composition, source rotation or other methods.

(NOTE) Please see section “5.8 Regarding the problem of images becoming burnt onto the screen“ for details.

3)The following signals cause inferior image quality:

•Multifold-generation video sources copy of VTR signals

•Copyright protected signals

•Scrambled CATV signals

•Signals with significantly phase-shifted sync and video signals

4)Images are blacked out for approximately one to three seconds when input is switched, to permit the plasma display driver to temporarily suspend operation while video memory is refreshed. When you switch input between different frequencies, a longer black-out interval is needed (up to approximately three seconds) due to the array of data to be changed in video memory. Allow for this interval when “staging” video.

5)The fan will begin spinning faster when ambient temperature rises above 30 °C. This is normal.

6)About the plasma panel's screen-saver feature (Direction of still images)

Brightness will drop slightly when photo images or slow-moving images, such as those supplied by a PC, are shown for extended periods. The unit detects the lack of motion, and automatically dims the screen brightness to protect the plasma display panel. This is normal and does not indicate a problem.

•The feature generally kicks in approximately five minutes after powering-up or switching input in normal operating mode/menu mode. This feature does not function in RS-232C adjustment mode <AJY> or in integrator mode.
