Instructions
Turn on your Sony PS3 and the Jabra Bluetooth headset. Locate the voice button on the headset and hold it in until the headset light becomes either green or blue. This means it is in "discovery" mode.
Select "Accessory Settings" from the PS3 menu, then "Manage Bluetooth Devices" and then "Start Scanning," in order to allow the PS3 to scan for the Jabra headset.
Select "Jabra" from the list that appears. Enter in the passkey for the Jabra headset. This is either "0000" or "1234." Select "OK" to sync the two devices.
Press the "O" button to go back to the previous menu. Select "Input Device" until it reads "Jabra." Your Jabra headset is now synced to your PS3.
