25.16 CLEARING THE SCREEN
If the same character is displayed at the same position on the screen for
a long time, the life of the LCD will be shortened.
To prevent this from occurring, the CNC screen can be cleared. There
are two ways to do this: using the screen clear function, executed by
pressing a key, and automatic screen clear function, which
automatically clears the screen if there has been no key activity for the
time set for a parameter.
25.17 PERIODIC MAINTENANCE SCREEN
The periodic maintenance screen provides a guideline indicating when
consumables that require periodic replacement (such as the battery for
control unit backup and the LCD unit back-light) are to be replaced and
checked if their service lives are set in advance.
