I just recieved my new Blue Tooth adapter and headset and get intermittent unacceptable static when screen is on with 600. Of course it is on when making call, is it this unique phone or a general problem? Most reviews are positive with this headset combo. Is ti the phone or the headset? I hate to send headset back if it is a problem with this phone. Chicken or egg issue. Both company's are willing to try to make things right.
