6.1.3 Error Messages

tion represented by error messages are listed on page 14.)

mately 3 seconds. When an error condition disappears, an error message automatically goes out and the

month, day, hour and minutes of error occurrence and recovery. (Complete details are
covered in the Key Operation Manual.)
