Bluetoothproblems
For Windows 7 and Windows Vista
• Problem: Sound does not come from the Bluetooth headset/headphone but comes from the local
speaker even though the headset/headphone is connected using Headset profile or AV profile.
Solution: Do the following:
1. Exit the application that uses the sound device (for example, Windows Media Player).
2. Open the Control Panel by clicking Start ➙ Control Panel.
3. Click Hardware and Sound ➙ Sound.
4. Select the Playback tab.
5. If you are using Headset profile, select Bluetooth Hands-free Audio and click the Set Default
button. If you are using AV profile, select Stereo Audio and click the Set Default button.
6. Click OK to close the Sound window.
• Problem: PIM (Personal Information Manager) items sent from Windows 7 and Windows Vista cannot be
received correctly into the address book of any other Bluetooth-enabled device.
Solution: Windows 7 and Windows Vista send PIM items in XML format, but most Bluetooth-enabled
devices handle PIM items in vCard format. If another Bluetooth-enabled device can receive a file
through Bluetooth, a PIM item sent from Windows 7 and Windows Vista might be saved as a file with
the extension .contact.
For Windows XP

Places, but you cannot find anything.
