Operation

b. Checking. Carefully inspect the equipment for possible damage

incurred during shipment. Pay particular attention to the rotating

polarizer. If no damage is apparent, install the spinner and operate

it as described in paragraph 49.1.

c. Installation. With the spinner oriented so that the power switch

and speed control face upwards, slip the mounting clamp over the pro-

jector lens housing. Rotate the mounting clamp so that the parting

line (fig. 23.2) faces the projector screen. Tighten the screw that

secures the parting line of the mounting clamp.

d. Connections. Connect the power cable plug into an ac conven-

ience outlet. If available, use the one on the projector.

b. Preliminary Instructions. Rotate the pointer manually to be

sure the spinner is not binding Be sure the projector is operating

properly, and that a polarized transparency or n transparency with

polarized patterns is inserted in the copyholding device of the

projector.

c. Normal Operation. With lie projector on, operate the spinner

as follows :

(1) Pivot the spinner housing so that the rotating polarizer is in

line with the projector lens. He sure the rollpin is set in the

detent stop.

Note. The detent stop on the mounting clamp limits the amount of

swing to prevent knocking the power and speed controls against the

clamp.

(2) Press the power switch. Check to see that the power indica-

tor lights.

(3) Adjust the speed control for the rotational speed required

by the actual presentation.
