Using iPod 51
If you don’t see the lightning bolt or the plug, iPod may not be connected to a
high-power USB 2.0 port. Try another USB port on your PC.
If you can’t charge using a USB port on your PC, you can charge the battery
using the iPod USB Power Adapter.
To charge the battery using the iPod Power Adapter:
1 Connect the AC plug adapter to the power adapter (this may already be
assembled).
2 Connect the iPod Dock Connector to USB 2.0 Cable to the power adapter, and
plug the other end of the cable in to iPod.
3 Plug the power adapter in to a working electrical outlet.
Warning Make sure the power adapter is fully assembled before plugging it
in to an electrical outlet.
