Bluetooth is one of the common accessories that anyone has for their cell phone, it's simply a technology that allows the user to connect his phone to another phone or a PC or laptop for content sharing or he can receive the call that is on his/her mobile phone on a Bluetooth enabled headset.
The beauty of the Bluetooth headsets are that they don't consume the power from the mobile phone as they have own source of power.
To connect a Bluetooth headset to your phone, you should first have a Bluetooth compatible mobile phone.
Then unpack the headset and charge the same.
Turn on the Bluetooth feature in your mobile phone.
Turn on the Bluetooth headset and follow the instruction manual that has come with the headset for any special instructions.
In your cell phone select the settings menu and select Bluetooth.
The Bluetooth dongle that is how commonly the Bluetooth headset is commonly referred will be trying to find a transmitter/receiver and once we switch on the Bluetooth on our mobile phone that will be detected by the dongle.
Similarly the phone will also detect the Bluetooth dongle as another capable Bluetooth device.
Then when you select that dongle as a device it simply tries to pair both the devices.
There will be a pairing pop up dialog box that will be on the cell phone asking for the paring code.
Most commonly 00000 is used as the pairing code.
Once you enter the same and press ok, you will get a message saying pairing successfully completed.
After this you can receive calls on the Bluetooth headset.
