(PRESENCE UC DISCONTINUED). Voice prompts are the commands from the headset that let you know certain information (ie: "phone 1 connected" or "3 hours of battery left", etc). Voice prompts are enabled as the default factory setting. If you want to turn the voice prompts off please follow these steps: 1. Turn the Presence on but make sure it's not actively paired to anything (ie: have the cell phone Bluetooth turned off). 2. Press and hold both volume buttons until you hear 4 chimes and now voice prompts are disabled. NOTE: To turn voice prompts back on repeat steps 1 and 2.
