MX-7000N SELF DIAG AND TROUBLE CODE 8 – 4
(2) Power ON trouble detection sequence.
• When the power is turned ON and each trouble of H3, H4, H5, U1, U2, U6 (09) is stored, it is judged as a trouble immediately.
* For A0 and E7 troubles (connection troubles), only the connection trouble information is saved, and they are not regarded as save troubles.
* For A0 and E7 troubles (connection troubles), only the connection trouble information is saved, and they are not regarded as save troubles.
(There is no way to delete the communication trouble information.) (Detected every time when the power is turned ON.)
