When using near a device that emits radio waves such as a mobile phone, move your Walkman away from the device.

The content such as music on your Walkman may be corrupted.

Connect your Walkman to a computer, use Windows Explorer to delete the content in which noise has occurred from the Walkman. After you have deleted the corrupted content, transfer the content again from the computer to the Walkman. Do not perform any other tasks on the computer when transferring content to the Walkman. Doing so may cause the content to be corrupted.

If the plug is dirty, wipe it clean with a soft dry cloth.
