Im not familiar with that unit, but I am confused. They are not simple or cheap devices, so surely the manufacturer should be first port of call here. I have seen them, but never even looked inside. Some research does not bring back any information on that model at all? What exactly is it, and what are you trying to do. The multiple frequencies is somewhat odd too?
