T1. What should I do if the Bluetooth icon doesn’t appear?
• Make sure you have installed the Bluetooth driver if using Windows XP or Windows
7 system. And restart the computer after installing the driver.

disable all existing Bluetooth devices in Device Manager, then insert the adapter
and try again. To go to Device Manager: Right-click My Computer, select Manager,
go to Device Manager and disable all existing Bluetooth devices.
T2. Why the adapter is not working with my Bluetooth device?
