Warning: Do not leave stationary or letterbox images
IMPORTANT NOTES
The normal use of a TV should include a mixture of TV picture types. The most fre- quently used picture types should ll the screen with constantly moving images rather than stationary images or patterns. Dis- playing the same stationary patterns over extended periods of time, or displaying the same stationary pattern frequently can leave a subtle but permanent ghost image. To avoid this, mix your viewing pattern. Do not show the same stationary image for more than 15% of your total TV viewing in any one week. Display constantly moving and chang- ing images that ll the scr een wh enever pos- sible.
This projection TV uses picture tubes to proj- ect the image to the screen. All picture tubes age with use. As they age, their light output is gradually reduced. Normal TV pictures ll the scr een wi thconst ant ly changing images. Under these conditions, picture tubes age at an even rate across the entire screen. This maintains a TV pic- ture that is evenly bright over the whole screen. Stationary images or images that only partially ll the scr een ( l eavi ng bl ack
or colored bars to ll the scr een) , wh en
used over extended periods of time or when viewed repeatedly, can cause uneven aging of the phosphors and leave subtle ghosts of the stationary images in the picture.
Still or stationary images may be received from broadcasters, cable channels, satellite channels, DVD discs, video tapes, laser discs,
