Undo the Azimuth lock and manually turn the scope as far as it will go one way. Then come back all the other way and count the number of turns it takes. Then come back half way and lock the Azimuth with the forks and base lined up

If it is a GPS scope, then this is slow and overkill.
All you need to do is set the OTA to DEC = 0 then rotate on the RA axis till the diagonal/EP/camera is directly over the control panel.
Due to the position of the RA hardstops, there is only one way you can get to this position.
Thus just try to slew scope "gently" to this possie ( the stops really clunk when you hit them at speed )
If it hits the stop, go other way :-)
Done
( Unless yr on a wedge, in which case, you then reset the OTA to DEC = -90 ready for aligning )
As for Leons original question
If the GPS is on ( or you have manually entered/selected yr site ), it will detect yr latitude, and determine how to do the polar align from that. You follow the Nth hemi instructions, but replace Polaris with Sigma Octans.
Or you can cheat, ( lotsa different methods )
