LCD INDICATION FOR EXPOSURE COUNT (The first frame automatically set) Auto OFF Turn the main switch ON, and the shutter is released by depressing the shutter release button; the paper leader will be automatically wound up to the first frame. 15 frames can be exposed using a 120 film roll and 30 exposures with a 220 film roll. • When the 6-exposure 120 film is used with your camera, you can take about seven pictures. And, the shutter and the exposure counter LCD continue to work until about 12 exposures. As shown above, the exposure counter LCD indicates "1." During the shutter release operation, the LCD for the exposure count will flicker at one-second intervals, indicating that the given frame is being exposed. Thus. in the case of time exposure at the "B" (Bulb) position, exposure time can be accurately counted by flickering intervals. When it is noted that the film winding speed slows or the motor fails to operate, the batteries should be replaced at once. When motor function slows extremely, intermittent motor noise can be heard. 21
