sorry for the stupiidity Jethro, but can you xplain further what you mean by manual setting circles?
So there is provision for locking screws, perhaps the manufacturer has uprated the springs and has done away with the locking screws , they're not critical, if your collimation holds then dont worry about it.

Manual setting circles make use of an altitude and azimuth scale on the scope used in conjunction with appropriate software to point your scope at objects in the sky. Simply put the software generates a realtime ALT/AZ coordinate for an object you're interested in and you use the scales on your scope to point at the desired object...

Not sure how clear that is but see here http://www.homebuiltastronomy.com/ManualDobSettingCircles.htm for an example, there are many sites on the web on this topic, including cloudynights where there is a huge thread dedicated to it.

Again, this was a suggestion for later on maybe, after you have "run in" your new scope
