Unplug the USB cable, then reinsert it.
When connecting the Sound Repeater to the PC, if the Step 5 screen for the

Check PC settings with the following procedure:
Step 1. Select "My Computer" – "Control Panel" – "System."
Step 2. Click "Device Manager" in "Hardware."
Step 3. Check to be sure that there is no "!" or "X" symbol in "USB Controller"
and "USB Root Hub." When "!" or "X" symbols are displayed, perform
settings so that USB can be used. For the setting procedure, refer to the
PC instruction manual.
When the driver cannot be correctly installed, the Sound Repeater may be

Step 2. Click "Device Manager" in "Hardware."
Step 3. Click "Display" to select "Device (classified by type) (E)."
Step 4. Ensure there is no "Other Device."
Step 5. When there is "Other Device," click that tab. If there is "Unknown File"
under the tab, select and delete it.
Step 6. Remove the USB cable and after reinserting it, reinstall the driver.
Step 6. Select the source to copy.
Pull down the "Copy files from:" menu to select "\Driver" in the CD drive.
