MZERO FAIL CODES
In case of malfunction the MZERO system transmits to the MZD software a code corresponding
to the error detected by the MZERO.
To read the code, proceed as follows:
connect the MZERO (indicating FAIL by led) to the PC using the USB cable;
- launch the software MZD;
- use the icon for the connection; a window appears to request the password; enter the
password; a window appears with the error code occurred.
The following table lists all possible errors detected and their solution.
