second to btgs, basically yashica's manual is all the same in one series of product line e.g. lynx, electro or TLR...the difference might lies in minor technical difference like the battery, meter, exposure indicator, etc, but the operation is completely the same.
the rings, yashica lynx 14e has 3 rings eh? shutter speed, aperture and focus.
if you totally new to analog film camera, then you might want to read and learn the correlation between aperture and shutter speed, if you know it already, then all the ring stuffs might not even a problem
