What u just asked is like ringing up the power company and saying "I brought a electrical appliences at a store, and the clock is set to 24 hour mode, i want to know how to set it to am/pm mode", do you really think they can help you? there going to say "go ask the store it came from, we just supply the juice that makes it run, we dont deal with every last applience", let alone the fact you dont even tell them what the goods were, clock, dvd, nukebomb detenator, could be anything.
