I got the H500 given to me but not manual to show me how to make it work w/my cell phone
Starting with your headset turned off, press and hold the call button for more than 6 seconds, until the indicator light is steadily lit (you'll notice that the light will flash as if the headset was being turned on, but don't release the button at this step). You headset is now in pairing mode. Now, make your phone's bluetooth application search for new devices. After a while, the H500 will appear on the phone screen. If a pairing code (or PIN, or passkey) is requested, enter '0000' (four zeros). You just have to pair any two blueotooth enabled devices once. All subsequent connections between them should be achieved by bringing them both within range, with their bluetooth radios turned on. If they fail to do so, a simple press on the headset's call button should suffice to established the link.
Hope it works for you.
