Magazine and lts Loading
         The magazine consists of four parts: cart-
         ridge, outer cramp, inner cramp and reel. To
       open the magazine, remove the outer and inner
       cramps from the cartridge and take out the reel.
       Magazine is loaded with a film in red light or in
        complete darkness depending on the film type.          I
           Fix the film end under the spring and start                                                                                                                                                                                                                                                                                                                                                                   It        winding the film over the reel. Trhe light-sensitive
        layer of the film should face inside towards
        the reel axle.         the reel and pulling the                      'Holding
        loose end of the film do not tighten t,he winding

       Do not touch the light-sensitive layer both
        during the magazine loading and while handling
        the film. T,he film can be held only by the per-
         forated edges. Insert the reel with film into the
         cartridge, leave the film end passed between the
        cartridge dies, slip on the outer and inner
         cramps.
