Pairing Bluetooth crap SUCKS! !

I have a few bluetooth headsets, and today I was trying to pair my Plantronics Voyager 520. I read 5 or 6 instructions on how to do it and they all said "Turn the device on and place it in discovery mode". So, I turn it on and try all sorts of combinations of hold for seconds and double clicks and crap and nothing makes it "blink blue and red" to indicate discovery mode. I think maybe it is something in the phone, and cant see anything that i can do differently. I finally stumble on how to "re-connect" the headset, it says:

turn the headset off then
"hold and KEEP HOLDING"
the button until it blinks blue and red.

It takes about 7 seconds but it works, just remember you have to start from the headset off to put it back into discover mode. hope this helps someone ;)
