at http://medfmt.8k.com/mf/kb/yashica_e.html, I think I can see the counter window on the right side, above the film advance knob. If it works at all like my 124, just wind the advance knob until the 1 appears. It _probably_ should stop there.

On my 124, the serrated wheel does indeed count the number of frames that have gone by.
