Prizm IV started using in 2007. Very experienced with this machine. Never had any function problems until now. When I turn on machine it signals/jumps up &down indicating hits on objects without me ever moving detector. This sign keeps jumping all over digital display making it impossible to detect at all. Any ideas or does it need factory repairs? Thanks.
