Charging the iPod
You can charge your iPhone/iPod by connecting it to the USB port.
Standby charging
If the unit enters power standby mode while the iPod/iPhone is charging, the unit will switch to standby charging mode, and the iPod/iPhone will continue to be charged. When in standby charging mode, the power display light turns orange.
When the iPhone/iPod is fully charged, the unit automatically stops supplying power for charging and enters normal power standby mode, and the power display light turns red.
When the “Network Control” setting is “On”, the power indicator lights orange when charging is complete.
