Check Power ¶
Be sure that your dock is connected to a wall outlet or your computer so that it will charge your device.
Error Message "Charging is not supported with this accessory" ¶
This problem may be caused by a poor connection between the dock and your Apple device and can be resolved by disconnecting the iPhone/iPod and:
- Waiting a minute before reconnecting it to the JBL dock
- Cleaning the connectors on both the JBL dock and the Apple device
- Cycling the power of both the dock and Apple device

Check That Your iPhone/iPod Indicates that a Connection has been Made ¶

Volume at Zero ¶
Be sure that the volume is not turned off. Raise the volume on both your device and the JBL speaker.
Connected by Auxiliary Cord ¶

If the auxiliary cord fits loosely:
*disconnect then reconnect the auxiliary cord
*otherwise, see: Disassembling the Circuit Board
