Does your camera have a Lock on the Low Speed Dial?
Some models had a small lock added to the Slow Speed Dial so that it could not turn accidently.
This is an easy test. Just look at your Slow Speed dial.
If you make a wrong selection you can go back one step or all the way to the beginning one step at a time. If you simply get lost or want to look up another camera you can go straight to the beginning again and start over. Or, if you feel you don’t need all the explanations you can go to the Rapid Finder. You get the same questions but in abbreviated form with no discussion or photos.
