The secret is that the closer the mount is aligned on true North and level and having the tube parallel to the base, the better the alignment will be.
The first thing you should do is check the 'Home" position of the tube. It needs to be parallel to the base. So what I do is set the mount on a surface that is level. So the base is level and using a level, level the tube of the telescope. Then adjust the setting circle to read zero. Now you have that part of the Home position correct. You only need to do this once as long you don't move the Dec/Alt setting circle.
Now you take the telescope outside, I first get the mount close to level and then point it at Polaris so Polaris is in the eyepiece of the telescope. Now your pointing very close to true North. Now lower the tube in Altitude so the setting circle reads 0 and the tube is parallel to the base. So now the scope is pointing close to true North and also point close to the horizon so the scope is now pointing very close to 0 Altitude and 0 Azimuth.
Turn the telescope off and turn it on. The system now sees the position of the scope as 0, 0 and next do the alignment procedure. The scope is already in the "Home" position, pointing North and Horizontal. If you entered the time, date, Long and Lat of your location correctly then the scope should point very close to the alignment stars. Be sure the Daylight saving time is set correctly for this time of year and also that you have selected the correct telescope in the setup since the gear ratios are different for different mounts and that will cause it to be way off as well.
What these systems are doing is converting RA/DEC to Alt/AZ and then doing an error correction from Alt/AZ based on the errors it calculates from when you first align in on the two stars. So the closer the telescope is setup to be aligned on true Alt/ Az ie started out pointing at True North and at the Horizion , the smaller the errors and the better the pointing.
Happy Holidays !
