Note To prevent the formation of an afterimage, either use the screen saver function
or periodically switch screens.
S The screen can be made to enter the no-display state by specifying screen No.
0. In this state, however, the backlight remains lit or flashing.
S While the screen is in the no-display state, only screen switching operations
from the host are permitted.
S Even though the screen display is set to off, the display of the screen immedi-
ately before the screen is turned off remains output by the PT.
If this method is used, the screen is automatically turned off when no operation is
attempted for a preset length of time.
Using the system menu of the PT, set a value other than 000 for Screen Saver
Start up Time (the length of time before the screen saver is activated after the
last PT operation) and Display erased for Screen Saver Movement. (The screen
saver function is not executed if 000 is set for Screen Saver Start up Time.)
Screen Saver Movement, the character string set in character string table No. 0
is displayed on the screen at random. In this case, the backlight is not turned off.
If the PT has not been operated (touch switch operation, screen switching op-
eration) for the preset length of time during operation of the PT, the screen is au-
tomatically turned off.
This method makes it possible to turn off the screen at any required time.
