To charge the battery, connect iPod nano to a high-power USB 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. Loading information onto iPod nano using FireWire is not supported.  Try the 5 Rs, one by one, until iPod nano responds. If you want to disconnect iPod nano, but you see the message "Do not disconnect"  If iPod nano is loading music, wait for it to complete.  Select iPod nano in the Source pane, and click the Eject (C) button.  If iPod nano disappears from the list of devices in the iTunes Source pane, but you still see the "Do not disconnect" message on the iPod nano screen, disconnect iPod nano.  If iPod nano doesn't disappear from the list of devices in the iTunes Source pane, drag the iPod nano icon from the desktop to the Trash (if you're using a Mac) or click the Safely Remove Hardware icon in the system tray and select iPod nano (if you're using a Windows PC). If you still see the "Do not disconnect" message, restart your computer and eject iPod nano again. If iPod nano isn't playing music  Make sure the Hold switch is not set to HOLD.  Make sure the headphone connector is pushed in all the way.  Make sure the volume is adjusted properly. If you see a lock to the right of the volume bar, a volume limit has been set. You can change or remove it by using Settings > Volume Limit. See "Setting the Maximum Volume Limit" on page 26.  iPod nano might be paused. Try pressing the Play/Pause button.  Make sure you are using iTunes 7 or later (go to www.apple.com/ipod/start). Songs purchased from the iTunes Store using earlier versions of iTunes won't play on iPod nano until you upgrade iTunes.  If you're using the iPod nano Dock, make sure the iPod nano is seated firmly in the Dock and make sure all cables are connected properly.  If you are using the Dock line out port, make sure your external speakers or stereo are turned on and working properly. If you connect iPod nano to your computer and nothing happens  Make sure you have installed the latest iTunes software from www.apple.com/ipod/start.  Try connecting to a different USB port on your computer. Note: A USB 2.0 port is recommended to connect iPod nano. USB 1.1 is significantly slower than USB 2.0. If you have a Windows PC that doesn't have a USB 2.0 port, in some cases you can purchase a USB 2.0 card. For more information, go to www.apple.com/ipodstore. 46 Chapter 5 Tips and Troubleshooting
