My iPod tells me apple/support/iPod but I can't understand DX

I definitely let the battery drain. it was shut down and when I connect it to charge the battery in the laptop, was kindled and introduced the apple logo for several minutes and then showed a message saying: please wait very low battery. after waiting, it displays another message that said: apple / support / ipod
