Change the backlight if the screen of the display device has become difficult to look at
due to the reduced luminance of the backlight. (The screen save and back light OFF
functions of the GOT are used to prolong the service life of the back light. For details,
refer to the GOT-A900 Series Operating Manual (GT Works Version5/GT Designer
