Backlight OFF Function

In order to prevent the formation of an afterimage on the screen, and to maximize
the service life of the backlight, the NT11S has a function for turning off the back-
light.
After the backlight has been switched off by actuation of the backlight OFF func-
tion, it will come back on in response to any key operation on the panel of the
NT11S, if a screen is switched or redisplayed by the PC, or if a backlight ON
instruction is received from the PC.
The backlight will not come back on merely because the numerals or characters
displayed on the screen change.
There are two methods for implementing the backlight OFF function:
- Method whereby the backlight is automatically switched off when there have
been no operations for a set length of time.
(Designated with the memory switches)
- Method whereby the backlight is switched off by an instruction from the PC.
(Designated in the PT status control area)
For details on the method for switching the backlight off with an instruction from the
PC, see 5-4 "NT11S Status Control" (page 122).
The settings relating to the backlight OFF function that can be made with the
memory switches are: whether or not the backlight OFF function is used, and - if it
is used - what length of time will elapse before the backlight goes OFF.
The setting on shipment specifies that the backlight will go OFF after a period of
ten minutes during which there are no operations.
Select the backlight OFF time by performing the following operations, starting
from the system menu.
