According to the very early manual copy I have, it is just two solder links that need to be altered, on unit 10, the main pcb, adjacent to the sound modulator unit.
The manual states: Close solder joint I, Open solder joint H.
There does not appear to be a solder joint I, there is however one marked J. The PCB layout that another member kindly uploaded, doesn't show solder joint 'I' either.
This might just be a typo in the manual I have. could I ask if it is the same in your manual, or is it indeed 'J'?

I think the supplement to the service manual I have has some amendments to the links and their combinations for the various options. I'll scan it tomorrow and post here (and the relevant pages from my service manual).
