3-8-3 Screen Saver Function (NT620S) / Backlight OFF Function
(NT620C)
The NT620S/NT620C has a function that turns off the screen display if no opera-
tion is performed for a certain period of time to maximize the service life of the
backlight and prevent the formation of an afterimage on the screen (in the case of
the NT620C, the backlight is also switched off at the same time).
Continuous display of the same pattern for an extended time (as a guide, about 1
hour) will lead to the formation of an afterimage.
In order to prevent this, either use the screen saver function or periodically switch
screens.
Redisplaying a Screen that has been Turned Off
After the screen has been turned off by the screen OFF/backlight OFF function
it will be redisplayed if a touch switch is pressed, or if an instruction to switch the
screen or redisplay the same screen is received from the PC (in the case of the
NT620C, the backlight will also be turned back on at the same time). Changes
in numerals or character-strings displayed on the screen will not cause the
screen to be redisplayed.
Setting the Screen OFF/Backlight OFF Function
Use the memory switches to set whether or not the screen OFF/backlight OFF
function is used, and the length of time that the screen is turned off if it is used.
