im trying to find out how to pair my bluetooth to another phone but the thing is that the bluetooth i have is a plantronics 520 and in order to know that its is trying to pair with a phone is as if its blinking red or blue, but the thing is its not doing that and i dont know how to make it pair again, all i could do is turn it off and on again but still no luck, i already know the password and that 0000 but i need to figure out how to reset it or make it connect to another phone?
