You need to print this out and read carefully. Its pretty much a step by step instruction on how to connect things and update the firmware. It was written for 1.5, but applies to 1.6 as well.

Everything needed (software) can be found on hyperions site - look around forit, its plainly labeled. If you're uncomfortable doing this, ask the place where you bought your 0610i if they will do it for you (how much)? If you got it locally may not be a big deal, but if not, will require sending it in and waiting.
