Does the iPod Hi-Fi charge the iPod while running from batteries?
If you are using the iPod Hi-Fi with batteries (and not plugged into an electrical outlet) and you connect an iPod with a dock connector, the batteries in your iPod Hi-Fi provide a minimum charge to iPod. If the iPod is on, it charges for 30 minutes. If the iPod is asleep, it charges for 15 minutes. If you disconnect the iPod and reattach it, the charge cycle starts again. The best way to charge an iPod connected to the dock connector port is by connecting the iPod Hi-Fi to AC power. Note: You cannot disable the iPod Hi-Fi from charging an iPod connected to the dock connector (you can connect iPod to the audio input port and iPod Hi-Fi will not charge iPod, but you will not have access to some functions of the remote).
