This was an anticlimactic pair of pages. The process here is to pull the Skyview computer out and remove the screws holding the ignition module in place on the left panel. This allows you to have access to the potentiometers inside the AV-5000A ‘magic box’ so the various audio levels can be adjusted. The Book states that the potentiometers are pre-adjusted to such-and-such a value (number of turns), but that I am to fiddle with them to get certain audio characteristics. Turns out that the factory settings were just right and no adjustments were needed. Everything got put back. No photos taken.
