I realize that this will be considered heresy, but make a "shop copy" of the owners manual. Read it thoroughly, make marginal notes if necessary, and highlight the important sections.
Keep the original manual in a folder with other tool manuals and parts diagrams. Place the marked up copy with the jig.
Once you made a few test pieces and found one that fits, keep it, and mark down what bit was utilized. Also mark the router base so as to keep the same edge to the rear of the jig. Some router bases are not perfectly round, there could be some run-out in the collet, etc. Small errors on dovetail jigs, like box joint jigs, easily become large errors and usually are unnoticed until you do a test fit.
