- Will Not Turn On
Apple device's charge indicator does not appear when connected.
Be sure that your dock is connected to a wall outlet or your computer so that it will charge your device.
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
Power is on but the music will not play out of the JBL speaker.
If your Apple device does not indicate that it is connected disconnect and reconnect it to the JBL dock.
Be sure that the volume is not turned off. Raise the volume on both your device and the JBL speaker.
If using an auxiliary cord instead of the dock, be sure that the connection between the JBL speaker and your device is not loose.
If the auxiliary cord fits loosely:
*disconnect then reconnect the auxiliary cord
*otherwise, see: Disassembling the Circuit Board
Static, buzzing, and/or humming noises are playing through the JBL speaker while playing music.
Be sure that the input cord is not loose.
Distortion may occur when the volume level is too high for some devices. Lower the volume.
Change the EQ setting to flat or turn it off.
If the distortion only occurs on some songs, those songs may have been recorded or downloaded improperly. Re-download those songs from another source.
