Before you begin, make sure that your Bluetooth enabled headset is not

to learn how to search for or add new Bluetooth devices.
To pair and connect a headset:
1.  Press MENU/SELECT on the handset in idle mode.
2.  Press  CID or  DIR to highlight Bluetooth, then press MENU/SELECT.
3.  Press  CID or  DIR to highlight Add BT headset, then press MENU/SELECT. 
The handset displays Search headset....
4.  Set your headset to discoverable mode (refer to the user’s manual of your 
headset). When the screen displays the found devices, press  CID or  DIR to 
highlight your headset, if necessary, then press MENU/SELECT.
If you have trouble pairing your headset, it may not be compatible  
with your DL72130/DL72210/DL72240/DL72250/DL72310/DL72340/DL72350/
DL72510/DL72570/DL72580. Check the Bluetooth compatibility list at
