Query: Clock not working

When I received this item, back up battery was dead. Therefore the whole memory and all the programs were erased. I could have bought the battery and set up the unit manually but that would have defeated the purpose. I can imagine this clock was sitting in the warehouse for a long time and battery went dead. I suggest that seller should test the product before shipping it and spare his customers disappointment.
