The LCD backlight must be replaced periodically. Replace the unit in
which the LCD backlight is mounted.
The LCD backlight has a life of about 10,000 hours (5,000 hours
guaranteed). (During its lifetime, the backlight should maintain a
brightness exceeding 50% of that when new.)
Upon reaching the end of its service life, the LCD backlight unit must be
replaced. The unit can be replaced either by the user or by a FANUC
service engineer.
Remark) When the screen display is not required, the display and
backlight can be turned off by pressing a key.
Doing so will increase the useful life of the backlight.
