Field-Replaceable Legends

Legend RemovalLegend Replacement
To replace a legend, align the text correctly, and then apply gentle pressure until the body of the legend support seats firmly into the faceplate.
Once the new legend is in place, ensure that it has seated correctly by checking that it illuminates. The unit is now ready for use.
Jupiter Avionics Corporation (JAC) products have field-replaceable illuminated legends. This permits easy customization, and allows the same units to be used in multiple different configurations with only minimal changes.
The internal circuitry ensures that, although the legends are individually illuminated, the illumination is consistent and uniform throughout all legends, andnever needs to be balanced. This means that if it is a requirement to change the labelling due to damage or for a different project, there is no need for costly and time-consuming illumination checks.
