I got a new resperate about 4 weeks ago. When I first recieved it it recognized my breating right away and would start the program within a minute. Now it works occaisionally. I have to fiddle with the sensor placement. I have tried all sorts of things, I have changed the batteries. Tried wearing differe (IMG:http://forum.resperate.com/style_emoticons/default/sad.gif) nt shirts. Moved the sensors up and down. Sat in differennt positions. It is most frustrating and now I am becoming relucant to use it because of the hassle factor. My breath recognition was up at above 80% within the first two weeks and now it is down below 50%. Can anybody offer some advice.
