It´s quite simple:
It moos always if price is climbing.
If you choose as alarm for example the column "last" and you have as last Price for example 6.1698 (at the Moment).
Then you should enter in the top-field in column "last" a value which is higher than 6.1698 for example 6.5.
It could be that it needs some seconds to reset during entering the value. Wait until the green LED at the Bottom flashes again and then it should be finally resettet.
Next time it will moo when the "last" price of Bitcoin at Mt.Gox will go to 6.5 (OR EVEN HIGHER!).
Same for the "bears":
If you enter a LOWER price in the last-column-field "low" then the you hear the bear if the price falls to this price (OR EVEN LOWER).
