If the unit is doing the same thing that the last one did I suggest that you call the manufacturer and tell them to bring out another one. Or better yet tell them to bring out a diffrent model as it is apparent that this one is seriously flawed in its design.
Do not accept another model of the same series. Demand that they provide you with a model thatr is comparable in price and features or greater.
It is you that are being inconvienienced here. Make sure that they know this, and do not let them for one minuet make it sound like you are being unfair, or that you are in any way, form, shape, or fasion in the wrong.
If they balk at replacing the unit then ask to speak to that persons superior. Keep doing this untill you get the answer that you want. Write down every persoins name that you speak to and a summery of the conversation after the conversation is over.
Be persistant. Call multiple times a day if you need to.
Remember that the squeeky wheel gets the oil. So squeek loudly and often.
