u Precautions when Connecting
An hourglass figure may remain projected on the screen after you connect the calculator
to a projector (or YP-100). Also, changing to another screen while a graph is being drawn
or while a PRGM mode program is running could possibly result in the projected screen
being different from the calculator screen. If this happens, performing some operation on the
calculator will restore normal display.
If the calculator stops operating normally, disconnect the USB cable and then reconnect it. If
this does not correct the problem, disconnect the USB cable, turn the projector (or YP-100)
off and then back on, and then reconnect the USB cable.
