 If that doesn’t work, you might need to restore iPod software. See “Updating and
Restoring iPod Software” on page 47.
Note: You can only use an iPod Dock Connector to FireWire Cable for charging and not
for downloading songs and other audio files to iPod nano.
If you see a folder with an exclamation point on the iPod nano display
 iPod nano might need to be reset (see page 43).
 If that doesn’t work, your iPod nano battery might need to be recharged. Connect
iPod nano to your computer and let the battery recharge. If you still see the folder,
reset iPod nano again.
 If that doesn’t work, you might need to update or restore iPod nano with the latest
software. Make sure you have installed the software from the iPod CD, or go to
www.apple.com/ipod to get the latest software. Then follow the instructions on
page 48 to update or restore the iPod software.
If you connect iPod nano to a USB port and it doesn’t work correctly
 A USB 2.0 port is recommended to connect iPod nano. USB 1.1 is significantly slower
than USB 2.0 and is not recommended. If your Windows PC doesn’t have a USB 2.0
port, you can purchase and install a Windows-certified USB 2.0 card and install it. For
more information, go to www.apple.com/ipod.
 To charge the battery, you must connect iPod nano to a high-power USB 2.0 or
FireWire port on your computer. Connecting iPod nano to a USB port on your
keyboard will not charge the battery. You can connect iPod nano to a FireWire port
using the optional iPod Dock Connector to FireWire Cable for charging the iPod nano
only. Transferring information to iPod nano using FireWire is not supported.
 If you’re connecting iPod nano to a portable or laptop computer using the iPod Dock
Connector to USB 2.0 Cable, connect the computer to a power outlet before
connecting iPod nano.
