Caution
- Do not press touch switches carelessly while the backlight is off or while noth-
ing is displayed on the screen. Otherwise the system may operate unpredict-
ably.
Only press touch switches after confirming system safety.

To prevent the formation of an afterimage, either use the screen saver function
or periodically switch screens.
3-8-4 Resume Function
The NT620S/620C has a function to protect the contents of the memory table
(value setting key input, data from the PC, etc.) from being erased even if the
power to the NT620S/620C is shut off during operation. This function is called
the resume function. Setting the resume function protects the memory table from
being initialized even when the power is turned on or reset or when the mode is
switched to the “RUN” mode by the System Menu operation.
The screen displayed before the power is turned off will be displayed again when
the NT620S/620C is started next time.
If the “Init. Memory Table” is selected in Initialize Memory Menu from the Mainte-
nance Mode Menu, the memory table will be initialized regardless of whether or
not the resume function is set to ON or OFF. For the memory table initialization,
refer to “Initializing Memory” (page 63).
Note
If the voltage of the battery in the NT620S/NT620C gets too low, the contents of
the memory tables cannot be saved even if the resume function is effective.
Use the memory switches to set whether or not the resume function is used.
The factory setting is not fixed.
