1.9 EMERGENCY DISPLAY
Whenever some abnormal signal is input to the syscon CPU,Example (in case of the error number E01):
an error number (E01, as an example) is displayed on the
LCD monitor or (in the electronic view finder).
In every error status, such the message as shown belowE01 E01
alternately appear over and over.UNIT INREMOVE AND
