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 Section 5 Test
Runs and Error Processing for troubleshooting information.)
Follow the procedure below to display and clear messages.

pressing MONTR until all messages have been cleared. These are some
