z If an hourglass figure appears in the image projected from the Data Projector when you
connect the calculator, perform some operation on the calculator. This should cause the
hourglass to disappear and enable normal projection.

disconnecting the USB cable from the calculator and then reconnecting it. If this does not
correct the problem, disconnect the USB cable from both the Data Projector and the
calculator. Turn the Data Projector off and then back on again, and then re-connect the
calculator.
