Problems when using the UA-20

Operating system becomes unstable

•Operation becomes unstable when the computer is started up with the UA-20 already connected

Please start up your computer with the UA-20 disconnected, and then connect the UA-20. On a computer that uses a USB keyboard, starting up the computer with the UA-20 already connected may cause operation to become unstable. In this case, start up the computer with the UA-20 disconnected, and then connect the UA-20.

No sound

•Are you running multiple applications?

If multiple applications are running simultaneously, an error message may appear. If this occurs, click [OK] and exit the other applications.

Even if an application window is closed, it is still running if it appears in the taskbar. Be sure to exit unneeded applications displayed in the taskbar.

•Was the driver installed correctly?

•Did you reconnect the USB cable?

Exit all applications that are using the UA-20, and exit all applications that are using the UA-20, and re-connect the UA-20.

•Have you selected “Game compatible device” or “Voice modem” as the output for the audio track?

If game compatible device or voice modem (the actual name will depend on the computer you are using) is selected for the audio track of your software, the audio track may not play back. Do not select these devices as the port.
