An Emerson Bluetooth headset can be reset by syncing it with a phone or other device. If the Bluetooth is already synced to a device, it is possible to add a new device by switching the Bluetooth off and setting it to visibility mode, allowing the device to find it.
Set an Emerson Bluetooth to visibility mode by pressing the "Answer" button on the front of the headset. Hold the button for five to ten seconds, until the indicator light flashes red and green. Place the Bluetooth near a device and use the device to search for a new Bluetooth headset. If prompted to enter a password, type "0000" which is the default password for all Emerson Bluetooth headsets.
