Autostar then prompts you to enter the nearest city (listed alphabetically) to
the observing site. Use the Scroll keys to cycle through the database of

Autostar then prompts you to enter the model number of your telescope. Use the
Scroll keys to cycle through the list of telescope models. Press ENTER when the

Note: Autostar only prompts you to enter Country/State and City and
model number the first time it is activated. These prompts do not appear
again, unless you reset Autostar (see

RESET

, page 31). However, if you

need to enter this information (e.g., you change your geographic location),
you can do so by using the Site option of the Setup menu. See 

ADDING

OBSERVING SITES

, page 32, for detailed information.

10. System Initialization is complete and the display reads "Align: Easy." After per-

forming the Initialization procedure, you MUST train your drive. 

Training the Drive (Autostar Models Only)

Next, train the drive using Autostar. Perform this procedure the first time you use
Autostar with your telescope, after a Reset, or if you are experiencing any pointing
accuracy problems. Training the drive gives your telescope a higher degree of point-
ing 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.
Complete this exercise once every 3 to 6 months to maintain the highest
level of telescope pointing accuracy.
