12. Error Code
If the motor handpiece stops due to an abnormality such as a malfunction, overload, break or wrong use, it
automatically checks the state of the control unit and detects the cause of the abnormality and displays an
error code on the LCD panel. If an error code is displayed, turn on the power again and check whether the
same error code is displayed. If the same error code is displayed, take action by referring to the instructions
provided in the "Check/Remedy" column in the following table.
