Apple Duo 270C manual Starting the tour

Starting the tour

1.Roll the trackball to move the arrow pointer around on the screen.

Place the index finger of your dominant hand on the trackball and the thumb of the same hand on the lower trackball button. Don’t press either button yet.

Watch the arrow on the screen while you roll the trackball, and notice that the arrow moves in the same direction that you roll the trackball.

You may need to roll the trackball around for a few seconds to “break in” the mechanism so it works smoothly.
