Volume Knob

My newly bought second hand nait xs has a loose volume kbob so you can actually pull it off if you not careful, but easily put it on again and it works fine, also the green light marker. 

This may sound weird. The problem is that I can't remember where the green light marker on the volume kbob exactly starts and ends.

Can someone please sent my a picture of a naim amp with the volume kbob all the way down and also all the way up, so I can put it precisely on? 

Thanks :-)
