This unit does not support a USB mobile battery and USB power adapter. To supply power to this unit with USB bus power, use a USB port of a computer.

Furthermore, the unit may not be able to operate on USB bus power due to the power supply capacity of the computer being insufficient.
Check the following items.

• The USB power supply capacity of a USB port of the computer is low. 　-> Connect to a USB port that provides sufficient power. Furthermore, if the computer is running on its battery, supply power from the AC adapter.
• Other USB devices are connected to other USB ports of the computer. 　-> Disconnect the other USB devices to secure power for the USB port.
• Headphones with an impedance of less than 32 Ω are connected. 　-> Connect stereo headphones with an impedance of 32 Ω or higher.
• Headphones are connected to both the stereo phone jack and the stereo mini-phone jack. 　-> Connect headphones to either just the stereo phone jack or just the stereo mini-phone jack.
• The computer is connected with a USB cable other than the included cable. 　-> Connect using the included USB cable.
• A USB hub is being used. 　-> Connect directly without using a USB hub.

The master volume and headphones volume knobs on the computer screen cannot be operated from the controller.

If you run a laptop powered by the battery in it, a power saving mode may be automatically activated to cut the clock signal inside the CPU. This may affect the controller and make it unstable. In such a case, connect the laptop to an AC adaptor.
