3. ERROR INDICATIONS
This machine includes a self-diagnosis function. If the machine does not work normally it
judges that an error has occurred, and indicates the corresponding error message on the LCD,
which in turn helps the service men to quickly find out the problem.
3.1 Error Codes
The errors with a mesh background in the table below do not occur in the normal operation.
They might occur due to noise around the installation site, change of the power supply
voltage, and failures in the software.
