I've misplaced my owner's manual for this camera, but would like to shoot Rollei 400IR 35mm film in it. The problem is that this film is not DX coded. When I tried to load it, the camera didn't recognize there was film in the chamber, so would not load it (as the camera loads automatically). I assume it uses the DX coding on the canister to sense there is film to be loaded. Does anyone know if there is any way to load this film and set the speed manually? A quick search of the web seems to indicate there is not. Thanks!
