(4) When the presentation has been completed, press the power

switch.

(5) With the spinner motor turned off, but with the spinner

housing in position, any segment of the polarizer cycle can

be emphasized by rotating the pointer to the required position

on the scale. This operation is used to highlight a single

point in the demonstration. A slow-motion effect can be

obtained by moving the pointed back and forth by hand.

The scale is limited to 180°, but within this arc all effects of

polarization can be demonstrated.

Caution: DO not rotate the spinner manually when power is applied.
