I'm not sure how Vedal train Neuro to learn the manual.
Why not assign names to each symbol and create a glossary?
The person defusing the bomb could then use the glossary to identify each part by name.
Here's an example I found in a Steam guide:

(This is my totally uninformed idea haha)

I think he wants a system where it would work for everyone without any prior knowledge of this game, without anyone having to learn anything or to feed Neuro some kind of descriptions.
For example, some call a symbol a six, others call it a flat six, and Camilla says it's a fucking upside-down 9.
So I think Vedal would want a system where Neuro 'interprets' the players descriptions of the symbols rather than having a set word for everything.
All of this is just my speculation without any base or proof so im prob just making shit up tho
