5. Camera loading
Put the batteries into the camera in the following way: turn cap 22 counterclockwise so that its slot
take the horizontal position, remove the cap and take out the exhausted batteries should there be any.
Put new batteries into the compartment with signs “+” outward (upwards).
Replace the cap with its slot in the horizontal position and turn it clockwise by 90° to set the slot in
the vertical position.
Check the indicating light for operation. To do this, looking through the viewfinder eyepiece press
the release button 5 till a definite stop is felt. If the light-emitting diodes (one or both) light up it means
that the power supply operates properly.
Load the camera with film in the following way:
— lift the film rewind crank 12, pull out the rewind knob 11 as far as it will go, and open the
camera back door;
— put a loaded cassette into the chamber 21;
— return the rewind knob 11 to a locked position slightly turning it, if required, to let the spool
guide enter the cassette;
— draw out a film leader as long as to reach the camera edge and insert it into the slot of the take-
up spool 25; in so doing make sure that a sprocket 24 tooth engage a film perforation hole;
— close the back door 26, tightly pressing it to make the lock latch;
— to transport a nonexposed portion of film to the film gate, cock and fire the shutter twice. In so
doing the frame counter should be set at “0”.
Should the film be wound tightly in the cassette, the film rewind knob will rotate when the shutter is
being cocked. If the film is loose in the cassette, the rewind knob will fail to rotate at the first frames;
— set the speed of the film loaded in the camera by turning dial 13 till a corresponding film speed
value is click-stopped against the index mark 15.
Bear in mind that wrong setting of the film speed with the dial 13 will result in wrong exposure.
