Most devices come with a user manual, to send an electronic product without one is poor management. Perhaps your "specific" device was just overlooked ... if not, I would be writing to the head office demanding an answer as to why they feel everybody should just work things out for themselves. Anyway, you can get a user manual in .pdf format here: http://funadvice.com/r/bj853dsigj9 and there are some basic instructions here: http://funadvice.com/r/1540gavl5ht
It might be self explanitory or easy to figure. im sure somewhere theres a warning on what not to do with it, how you can reach the peole or a contact number to get ahold of someone if something goes wrong/ a problem occurs - like on the box, a piece of paper or something. just play around with it and soon you'll get the hang of it.
