3. Whenever dust has accumulated on the screen.

Clean the touch screen as follows:
Go to Utilities,
→
PC Settings. Touch the Touch Screen Cleaning icon. A
blank screen display appears. A blank screen display appears, thereby
making any dust on the screen easy to view, and easy to clean.
Do:
1. Use standard glass cleaning liquid, applied to a clean cloth, to
wipe the touch screen.
2. Use only a clean, soft cloth.
Don’t:
1. Spray glass cleaning liquid directly on the touch screen. Apply
cleaning fluid only with clean cloth.
2. Use any hard or sharp materials to clean the touch screen.
3. Use a sponge or hands to clean the touch screen.
4. Apply pressure while cleaning the touch screen
PC NC Mode of Operation
The PC NC operation modes can be broadly divided into two categories:
the online mode and the offline mode. Although the operation mode can be
switched using the switch settings, it cannot be switched during operation.
(The PC NC references the system number switches only at system start-
up.)
** If the system is started after the system number switches are set into
undefined numbers, or the hardware check program has not been booted
and the system number switches are set as B &C, a “Boot Log” message
appears and the system will not start normally.
