Remote Trainer

using remote trainer to train your dog?
So far, I'm having success in training my dog w / this new system. Has a negative tone noise only a dog can hear people say that dogs are not good behavior and a positive influence field to train your dog w / response positive influence this is the pitch positive influence, that only a dog can hear. Anyone out there have any experience with this system? I have curiosity and so far I've only had the system in a week, but have a positive experience.
I do it manually. My negative sound is "no" and my positive sound is "good dog ", which seems to work for me and millions of dog owners around the world. I worry about how to teach a dog" negative tone. " : (
