Windows XP
When installing the Desktop 9850, the operating system automatically assigns a drive for the Desktop 9850. This drive appears as a 'removable disk' in the Windows Explorer. Sometimes, the drive letter assignment for the Desktop 9850 conflicts with an existing drive letter mapping; this is why the Desktop 9850 cannot be seen in the Windows Explorer. Additionally, the software program displays the Desktop 9850 status as (disconnected).
Solution: Mount all network drives starting with drive letters Z, Y, X (in reverse alphabetical order).
PC sound system is not functioning
The Desktop 9850 is used as a USB sound device: Open the Sounds and Multimedia Properties dialog box in the Control Panel. Make sure your PC’s sound system is in the Preferred device selection. Activate the Use only preferred devices option.
