Problems and Possible Solutions 8 - 13

I have used Update Driver in Device
Manager (Unknown device > Other
Devices) to try and install the Airplane
Mode driver. Windows encountered a
problem in attempting to update the driver,
and a yellow exclamation mark appears
in Device Manager against the Unknown
device.

It is very important that the drivers are installed in the order indicated in Chapter
4 (which is the numbered installation order on the Device Drivers & Utilities +
User’s Manual disc). This issue can occur when drivers are manually installed,
and not in the correct order.

If you have attempted to Update Driver from the Device Manager control panel
and have encountered problems, then use the method below to correct this:

To correct this problem:

Go to the Programs and Features (Programs) control panel in
Windows.

Select any installed Airplane Mode driver item (e.g. Insyde Airplane
Mode HID Mini-Driver), and click Uninstall/Change to uninstall the
current driver.

Restart the computer.

10. Insert the Device Drivers & Utilities + User’s Manual disc and click

Install Drivers (button).

11. Double-click the Airplane AP item in the menu.
12. Follow the instructions to install the correct driver (you will need to

restart the computer as part of the installation process).
