From this image you can see that the Podule Bus connector is not fully "home" even tho
the Podule is fully secured to the rear of the case.
To rectify this, remove the ViewFinder Back Panel by unscrewing the two retaining screws
and fit one or possibly two small washers between the plate and the Podule.
This will have the effect of making the ViewFinder sit back further into the case.
This view better shows the packing washers in place.
