Why I cannot use my bluetooth headset with a Bluetooth mobile phone?
A7 : For devices to communicate with Bluetooth wireless technology, you will need to make sure that both devices have the Bluetooth functionality turned on. Even though the basic design of Bluetooth provides for an extremely low power consumption, the functionality can be switched off to save even more power, or to disable radio functionality in special situations such as during airplane take off. In most devices, the Bluetooth functionality is switched on by software. This is typically done from a menu choice, “Turn Bluetooth radio on”.
