Purchased this clock radio, because it appeared to be an "atomic clock", it is not it is self setting, and did not have the correct time. Once it was set to the correct time, it kept reasonably good time. That was the good part. After having it about 1 month it just quit, and the display looked like it was saying "help" I would not recommend this product. It was replacing an Emerson "atomic clock" radio, which had also quit functioning.
