Setting the Screen Saver Start-up Time
The NT631/NT631C has a function to maximize the service life of the back-
light and prevent the formation of an afterimage by turning off the screen dis-
play and the backlight if no operation is performed for a certain period of time.
The Screen Saver Start up Time setting determines the time interval before
the screen saver function operates.
The setting range is 0 to 255 minutes. The default (factory) setting is 10 min-
utes. If 000 is set, the screen saver function does not operate.
The screen saver can be canceled, and previous screen redisplayed, by any
of the following operations.
• Touching any part of the touch panel
• Screen switching due to PT status control area operations
• Screen switching due to bit memory table operations
• Execution of any of the following PT status control bit operations:
• Changing the backlight mode
• Screen printing (change from OFF to ON)
• Screen display (change from OFF to ON)
Reference:
• It is possible to display the character string stored in character string
memory table No. 0 at random positions and in random colors while the
screen display is off. For details, refer to 6-9-7 Setting Screen Saver
Movement (page 170). Note however that, when this feature is used, the
backlight does not go off.

started.
