I'd like to finish a roll which has had seven frames exposed. The manual and various webpages only explain the typical fully exposed roll removal that I am familiar with. What is the best way to wind the partial roll so that it can be removed for developing?
You can remove the back, then depress and hold down the pin that protrudes from one of the upper corners on the inner face of the back, then manually wind the dial on the side of the back until you feel no resistance. That'll do it.
