Training the Drive
Perform this procedure after a Reset, or if you are
experiencing any pointing accuracy problems. Training
the drive gives your telescope a higher degree of
pointing accuracy.
Note: Use a terrestrial object, such as a telephone pole
or lamp post, to train the drive. It is best to perform this
procedure during the daytime.
