5 incorporated for the manual film winding. Even when a frame has been completely wound, the knob will continue to turn without engaging for the film winding/shutter cocking function. 5. By turning the knob slightly counterclockwise after completing a single frame winding, the shutter can be released and the reflex mirror kept at the up position. The mirror will return when the film is wound manually for the next frame. When you finish winding the designated number of frames of the roll by repeating the above procedure, you can continuously wind without releasing the shutter till it is completely wound up on the spool. After completing film winding operation keep the film winding knob at the bottom of the camera body. Notes: • Should the knob be accidentally turned counterclockwise while you are winding manually, light leakage on the exposed film may occur through the fine slit of the shutter curtains. Precautions must be observed to avoid turning the knob in the opposite direction for this reason. • Avoid leaving the camera with the reflection mirror in the raised position in bright light, since light leakage may occur following shutter release. In addition, directing the camera in this state toward the sun could cause the shutter curtains to scorch through the rays of the sunlight. Before replacing with new batteries in the grip, do not fail to remove the film winding knob; else, the motor-driven film winding operation (restored due to the battery replacement) will also activate the manual film wind knob to simultaneously rotate at a rate of high speed. Finger or hand injuries could result if they are in contact with the knob at the time. To avoid overlapping, do not release the shutter before the red marking in a full circle becomes visible in the "shutter cocked" indication. 65
