Reading/Clearing Error Messages
This operation is used to display and clear error messages. It is possible to
display and clear non-fatal errors and MESSAGE instruction messages in any
mode, but fatal errors can be cleared in PROGRAM mode only.
Before inputting a new program, any error messages recorded in memory
should be cleared. It is assumed here that the causes of any of the errors for
which error messages appear have already been taken care of. If the buzzer
sounds when an attempt is made to clear an error message, eliminate the
cause of the error, and then clear the error message. (Refer to
Test Runs and Error Processing
for troubleshooting information.)
