Wrong file

Connection to the PC is not possible
USB driver has not been installed properly
Solution: Check whether the USB drivers have been installed correctly. If you did not complete the
installation of the USB driver or canceled the 'Unknown device detected' process the first time you
connected the DPM to your PC. Proceed as follows:
1. Connect the DPM to your PC.
2. Go to the Start menu, Settings, Control Panel, System, Device Manager.
3. Look for an unknown USB device in the list.
4. Select the Unknown Device and click Remove.
5. Click OK and close the Control Panel window.
6. Disconnect the DPM and reconnect it again.
7. The Add New Hardware Wizard is started. Click Next.
8. Follow the instructions which appear on the screen. When the wizard detects the driver (USB Mass
Storage Device), click Next to copy the driver to your PC.
9. On the last wizard page, click Finish to complete the installation.
Windows XP
When installing the DPM, the operating system automatically assigns a drive for the DPM. This drive
appears as a 'removable disk' in the Windows Explorer. Sometimes, the drive letter assignment for the
DPM conflicts with an existing drive letter mapping; this is why the DPM cannot be seen in the Windows
Explorer. Additionally, SpeechExec Dictate displays the DPM status as DPM (disconnected).
Solution: Mount all network drives starting with drive letters Z, Y, X (in reverse alphabetical order).
