7.4 Backlight for Liquid Crystal
The GOT contains a backlight for the liquid crystal of the display device.
The luminance of the back light lowers as it is used.
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
Version5 compatible Extended·Option Functions Manual).)
The replacement backlight changes with the GOT type. The backlights that may be
used with the GOTs are as follows.
