the operation disable message is made.
(NOT READY)
(Display) A dialog is displayed when a trouble occurs. For the mode where operations are enabled, [OK] button is added to the message.
When operations are disabled, [OK] button is not displayed, and the message is displayed until the trouble is cancelled.
* For U 1, 3, 5, 6, 7, perform the following procedures. (In order to avoid patent interference.)

The trouble display is always made, and all the modes cannot be set.

Writing of a same trouble to the trouble memory can be selected with SIM26-35. When this simulation is set, any trouble is written to the trou-
