(2) Trouble mode process
The machine can be operated under some conditions.
Operations except for the trouble mode are enabled (READY). For the
modes which cannot be operated, only setting is enabled and a mes-
sage is given to show the operations are disabled. (NOT READY in this
case)

(Display)
When a trouble occurs, a dialog is shown. In the mode where the oper-
ation is enabled, the OK button is added to the message. In the mode
where the operation is disabled, the OK button is not shown and the
display is kept until the trouble is canceled.

(3) Writing to the trouble memory
In case of a same trouble in this machine, selection is made with the
simulation to write into the trouble memory or not. If this simulation is
set, any trouble is written into the trouble memory unconditionally.
