To perform an end-plate (left-side set of switches) or side-plate (right-side set of switches) switch test, do the following:

●Remove the appropriate tray (for example, if you want to test SR20 or SR9, remove Tray 2).

●Watch for the corresponding bit to toggle from 1 to 0. It can take a few seconds for bits to toggle.

●Test each switch individually to see if the corresponding bit toggles from 0 to 1.
