How do I delete the pairing settings from my Nokia Bluetooth Headset BH-608?

To clear all the settings from your Nokia Bluetooth Headset BH-608, switch off the headset, and press and hold the power key and the answer/end key at the same time for about 8 seconds.

The headset beeps twice, and the red and green indicator lights change. After the settings are cleared, the headset enters pairing mode.
