Legend 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, and
never 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.
Caution
: Take care not to scratch or otherwise damage the faceplate or the legend.
To facilitate legend removal, JAC provides a legend extractor tool - part #
TOL-CUST-EXTR (figure 1) that fits into the recesses on the legend.
To remove a legend, hold the extractor firmly between
the forefinger and thumb, and use a tweezer-like action
to grip the legend (figure 2).
Pull the legend away from the faceplate as shown in figure 3.
