Dale, I don't know if you saw this post when I had the same problem:
Still, I couldn't get the handset to save a custom location.I was hoping that with accurate coordinates the alignment would improve. ES sent me a new handset that they had confirmed would accept a custom location. I was using the format in the Bresser manual of W---°-', N--°-', but it would not let me save it. Finally, I rounded off the latitude to N--° and dropped the minutes, and it worked. This tightened up the initial slew to the alignment stars to within my 20mm 68°view eyepiece.
