Some time ago I purchased a SRT202 on Ebay. The camera works fine except I have never seen the film presence indicator on the back, top, right corner of the camera. Can any one tell me how this device is triggerd and what it looks like when triggerd? Is it possible I purchased a SRT102 with a SRT202 cover on it?
Inside the takeup spool chamber, at the top as I recall, there is a sensor that the film operates. It is not uncommon for the decal (half orange and half black) to fall off the tab on the inside of the top cover. You would to remove the top cover to check this.
