How to adjust the focusing of the genuine lens of a core Indigo "micro A10" ?

[Lambda]

Hello again.

I just received my core Indigo "micro A10" with an additional spare lens.

(Here is a photo from the seller. Nice deal with good exchanges with him, by the way  )

See below this message, first photo

Very excited i am, but before doing some silly thing, being my first core (newborn i am, as you may guess  ), i wanted to ask you an additional prartical info:

How to manually modify the position of the lens for focusing properly a scene, target ?

The lens is without helicoidal possible movement or even slidable.... there is Alen screws ate the periphery of the housing, and front holes in the frame around the lens... I suspect that i would have first to unlock the 120° three peripheral Alen screws, and then using a proper spanner for screwing/un-screwing the main body of the lens???

Here is a photo made by Fraser in one of his previous threads, for more clarity:

If you could indicate me the manner to adjust manually the focusing of such lens, it would be great.

Thank you a lot.

Best regards.

You have to loosen all three
Hex screws round the lens
And then the lens can be rotated
To focus near or far   good luck
