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.

PIM items sent from the Windows 7 operating system cannot be received correctly
Symptom: Personal Information Manager (PIM) items sent from the Windows 7 operating system cannot be
received correctly into the address book of any other Bluetooth-enabled device.
