In addition to the external components listed in the previous section, the monochromator
card assembly, internal monochromator cable, and cable to the ScanDisk must be removed,
carefully packed, and shipped to Olis. Before removing the internal hardware
requiring upgrade, you will need to move the monochromator to 1000 nm to facilitate
accurate placement of the new sensor mount. Enter the RSM software and go to Live Display.
In Live Display, press "MMove RSM Wavelength" then type "1000."

Pictured above are the internal monochromator cable, the cable to the scandisk and the mono card assembly. |

| The original calibration sensor located on the mono card (circled, below left) will be replaced with a new sensor mount (below right) which you will install inside the DeSa monochromator. The original mono card will be upgraded and installed inside the new control box you will receive. |
