EM-200 polar alignment

Hello,

I took my em-200 out and tried to polar align. The instructions seem to be missing any reference to how to set the time by spinning the reticule. I winged it and the results were poor by about 3/4 of a degree every slew. I tried all the tricks I've read such as sync, go to Polaris then adjust the mount, but of course the reticule is wrong so I can't get it right.

Can someone point me to a complete set of instructions?

Thanks for any help. Kevin

Well aren't I the bright one. cwy I see now that the outside is the months/days and the inner is the time.

So I should line up my U time with the appropriate date and the reticule should be set.

I'll try it next clear night and see how it goes.

It is basically a planisphere, except that it only shows the pole star.
