There is no additional fee for such protection. On deposited materials carrying a service charge of $1, the AudioVisual Center assumes no responsibility for replacing damaged portions. Films must be returned on reels comparable to those on which they are received. Films should not be rewound after the final showing. Materials should be carefully packed and reshipped in the same cases and cans in which they are received. Printed return labels are included in all shipments; these labels should be used in order to insure prompt delivery of return shipments. The Center will submit quarterly statements of accounts. Payment should be made within 30 days. Educational agencies may make arrangements to pay at the conclusion of the school year, but not later than June 30. Checks should be made payable to Indiana University Audio-Visual Center. Use Restrictions Films rented from Indiana University are not to be used for television purposes unless the user obtains written permission from the copyright owners. Borrowers agree not to use materials where an admission charge is made for the privilege of seeing materials. Borrowers using films distributed by Teaching Film Custodians (TFC) agree to use the film exclusively as a part of the school’s instructional program, to charge no admission directly or indirectly, and to show each film as produced in its entirety. Care of Films Most film damage can be avoided if the operator observes the following simple precautions: 1. CLEAN THE FILM CHANNEL. Before the film is threaded, both aperture and pressure plates should be cleaned. To remove any accumulation of film wax and dirt in the film channel, clean it with a chamois skin or soft cloth moistened with carbon tetrachloride if necessary. Whenever scale is found adhering to the plates, clean with a wooden scraper; never scratch the parts with metal. Failure to clean the plates makes permanent scratches on the emulsion of the film, causing the film to appear “rainy” on following projections. 2. THREAD FILM PROPERLY, making sure that: a) The sprocket teeth are engaged in the film sprocket holes. b) The sprocket guards are locked in position. c) The film is centered in the film channel, so that the claws will engage the film sprocket holes. ) The film loops above and below the channel are of proper size. ) The tension on the take-up spindle is adjusted for the size reel being used. 3. BE SURE TO TEST THE THREADING by turning the manuallyoperated knob, which will move the film slowly through the projector. DO THIS BEFORE TURNING ON THE SWITCH. 4. STOP IMMEDIATELY AND RECHECK the threading if the film does not project properly or if damage is detected as the film passes onto the take-up reel. Loss of film loop either above or below the channel will cause damage to the sprocket holes of the film. Film also can be damaged by the last sprocket of the projector without discernible evidence of such damage in either the projected picture or the sound. This is true regardless of the make of the machine being used. 5. STAY WITH THE PROJECTOR while it is running. Damage to sprocket holes can be detected by checking the film between the thumb and forefinger as it winds onto the take-up reel. In this way damage, with. the exception of scratches caused by dirty film plates, can be detected and corrected at once. “_™N TG d e
