Operating system becomes unstable

Please start up your computer with the UA-700 disconnected, and then connect the UA-700. On a
computer that uses a USB keyboard, starting up the computer with the UA-700 already connected may
cause operation to become unstable. In this case, start up the computer with the UA-700 disconnected,
and then connect the UA-700.

Can't hear sound from the computer

• Is the Sampling frequency select switch set to "96 kHz REC"?
If the sampling frequency is 96 kHz, the Sampling frequency select switch must be set differently,
depending on whether you are recording or playing back. When playing back at 96 kHz, set the front
panel Sampling frequency select switch to 96 kHz PLAY.
