Non-recoverable system fault. If the Status lights are flashing any combination of red and green,
errors are present. Read the error code(s) before the machine is turned off.
Error Code interpretation through the Status light is detailed in the Service Manual. Individual code
digits are flashed in red with a long pause between digits. If more than one code is present, the codes
will be separated by a green light. Only active error conditions will be accessible through the Status
Light.
Error codes can also be retrieved with the Power Wave Manager Utility available at www.power-
wavesoftware.com). This is the preferred method, since it can access historical information contained
in the error logs.
To clear the active error(s), turn power source off, and back on to reset.
