i have a Mobile iphone model LG L70 and also an old Plantronics headset Model 05-12RIE. I am trying to pair my iPhone with this headset, but my iphone does not seem to discover it. I switched on the bluetooth Plantronics, the lights went from red and then when I pressed again, it turned blue. then on the iPhone I switched to the Blue tooth and switched it on, and tried to search for this bluetooth, but it could not find it. Maybe I am doing it all wrong or the steps, and hope the experts can please point me in the right direction, especially if there is a video on how to do it. Thank u.
