1. First of all, ensure the Hold key state. When red sign appears moving Hold button, the Hold function is open, and then all keys would be locked. Move the Hold button reversely, then the red sign is covered, it means the Hold function is closed; now you could use the keys on the machine.
(Notice: the buttons on wire controller are not restricted by the Hold button; wire controller could be locked by hold button).
2. Ensure whether the iPod is power-on. By 1394 (6 core) connection wire, connect iPod to an adapter or a computer. (The computer must have a interface with 6-pin front lines, 4-pin 1394 interface could only for data transmission). Connecting 30 minutes later, check the iPod screen, whether it has any display, if yes, it is at charging state, please wait until the charging finishes, and then you try opening the iPod.
(Notice: if there’s no any display at charging state, I suggest you send the iPod, connection wire and the adapter to repair center).
3.  If the iPod has no response and just like dead state, connect the iPod to a charger, open the “Hold” switch and then close it. Ensure the “Hold” switch is far from the position of the earphone hole, meanwhile, press “Play/Pause” button and “Menu” button for about 6 seconds until Apple trademark appears.
4. Under some unusual circumstances, iPod needs discharging completely and then to reset. If the steps above could not handle the problem, cut off the power for about 24 hours, and then connect to power sup
