XAV-2s DIP switch settings

[gatsu25]

I recently acquired an XAV-2s unit but I do not have access to a manual for it.

I'm hoping to find either an explanation of what the DIP switches do, or a scan of the manual.

Any help is appreciated!

I was able to find information on switch 1, but still unsure about the rest.

FM Towns Mode

The first DIP switch enables FM Towns mode. In this case, that simply means dis/connecting the pin 7 (composite sync in) from the RGB-15. If it's ON, the DB15 composite sync is fed into the CXA2075 circuit, at the same point (and connected directly to) pin 9 (composite video) on the RGB-21.

If OFF, C-sync is created elsewhere from the RGB-15 horizontal and vertical sync inputs.
