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.

try 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.
