Limitations and cautions
---------------------------------------------------------

1. On some computers, the driver does not load correctly if the SC-8850 is 
   already connected when Windows is started up. As a result, it will not be 
   possible to use the SC-8850 via USB. If this occurs, wait until after Windows
   has started to turn on the power of the SC-8850 (or to connect it).

2. If the computer enters stand by (suspend) mode while the SC-8850 is in use, 
   your system may not perform correctly after the computer resumes.
   If the computer enters stand by, wait until the computer resumes, then exit 
   all applications that use the SC-8850, and turn the power of the SC-8850 
   off, then on again.

3. If the USB cable is disconnected and reconnected while the SC-8850 is in 
   use, or if the power of the SC-8850 is turned off, then on again, it may 
   stop operating correctly.
   If this occurs, exit all applications that use the SC-8850, and turn the 
   power of the SC-8850 off, then on again.


Troubleshooting
---------------------------------------------------------

1. Cannot install/use the driver

   1.1) In step 5 of "Installing the driver," did the display indicate 
        "Unknown Device"?

        If the display indicated "Unknown Device" in step 5 of "Installing 
        the driver," use the following procedure to re-install the driver.

        (1) In the "Control Panel," double-click "System."

        (2) From the list in the "Device Manager" tab, double-click "Universal 
            serial bus controller" to open it, and find "USB Composite Device."

        (3) Click "USB Composite Device" to select it, and click "Properties."

        (4) Click "Driver," and then click "Update driver." The "Update 
            Device Driver Wizard" dialog box will appear, and the display will 
            indicate "USB Composite Device."
            Perform the installation again from step 5 of "Installing 
            the driver."

   1.2) Was the "USB Composite Device" driver installed?

        If you fail to perform the installation as directed in "Installing 
        the driver," the "USB Composite Device" driver will be installed, 
        and the SC-8850 will not operate. Use the following procedure to 
        re-install the driver.

        (1) In the "Control Panel," double-click "System."

        (2) Click the "Device Manager" tab, and from the list, double-click 
            "Sound, video, and game controllers" to open it, then look for 
            "USB Composite Device."

        (3) If "USB Composite Device" does not exist, proceed to step (4).
            If you find "USB Composite Device," click to select it, then 
            click "Remove." A dialog box will ask you to confirm, so click
            "OK."
            After switching the SC-8850's power off, then on again, perform the 
            installation again from step 5 of "Installing the driver."

        (4) From the list under the "Device Manager" tab, double-click 
            "Universal serial bus controller" to open it, and find "USB 
            Composite Device."

        (5) If "USB Composite Device" does not exist, proceed to step (6).
            If you find "USB Composite Device," click to select it, then 
            click "Remove." A dialog box will ask you to confirm, so click
            "OK."
            After switching the SC-8850's power off, then on again, perform the 
            installation again from step 5 of "Installing the driver."

        (6) From the list under the "Device Manager" tab, double-click 
            "Other devices" to open it, and find "USB Composite Device."
            Click "USB Composite Device" to select it, and click "Remove."
            In response to the request for confirmation, click "OK."
            Switch the SC-8850's power off, then on again, and perform the 
            installation again from step 5, "Installing the driver."


2. Cannot select the SC-8850 device

   2.1) Did your computer enter stand by (suspend) mode while the SC-8850 was 
        being used?

        If your computer enters stand by (suspend) mode while the SC-8850 is 
        being used, the SC-8850 may not operate correctly after the computer 
        resumes.
        If your computer enters stand by mode, wait until it resumes. Then, 
        exit all applications that are using the SC-8850, and turn the power 
        of the SC-8850 off, then on again.

   2.2) Was the USB cable disconnected and reconnected while the SC-8850 was 
        being used, or was the power of the SC-8850 turned off, then on again?

        If the USB cable is disconnected and reconnected while the SC-8850 is 
        in use, or if the power of the SC-8850 is turned off, then on again, 
        it may no longer operate correctly.
        If this occurs, exit all applications that are using the SC-8850, and 
        turn the power of the SC-8850 off, then on again.

   2.3) On some computers, if the SC-8850 is connected while Windows starts up, 
        the driver will not be loaded correctly, and it will not be possible to 
        use the SC-8850 via USB.

        If this occurs, start up Windows before you turn on the power of the 
        SC-8850 or connect it.

3. Cannot play back/record

   3.1) Could you have entered stand by (suspend) mode during playback or 
        recording?

        If you entered stand by (suspend) mode during playback or recording, 
        it will no longer be possible to play back or record from the sound 
        generator.
        Exit all currently playing or recording applications, and switch 
        the power of the sound generator off, then back on again.

   3.2) During playback or recording, did you turn the power of the sound 
        generator on/off, or disconnect and reconnect the USB cable?

        If you turn the power of the sound generator on/off or disconnect and 
        reconnect the USB cable during playback or recording, the sound 
        generator will no longer be able to play back or record.
        Stop playback or recording, and then start playback or recording 
        once again.
        If you are still unable to play back or record, quit all programs 
        that are using the sound generator, then turn the sound generator off 
        and then on again.

4. Part of the playback is wrong: e.g., notes are broken off prematurely, or 
   some notes are lost.

    Such problems may be solved if you uncheck the "Light Load" check box.

  * Note!
    Modified settings will take effect after you turn the power of the sound 
    generator on/off.
    Unless you experience problems, use the checked (initial) setting.
