1. Exit the application that uses the sound device (for example, Windows Media Player).
2. Open Control Panel and click Hardware and Sound ➙ Sound ➙ Playback.

• Problem: PIM items sent from the Windows 7 operating systems cannot be received correctly into the
address book of any other Bluetooth-enabled device.
Solution: The Windows 7 operating system sends PIM items in XML format, but most Bluetooth-enabled
devices handle PIM items in vCard format. If another Bluetooth-enabled device can receive a le through
Bluetooth, a PIM item sent from the Windows 7 might be saved as a le with the extension .contact.
