The manual control training collar I have, which is similar to the perimeter
fence ones. Its triggered from a handheld unit that's on 11m, one of the rc
frequencies and uses similar pulse width and frequency coding from the
sounds of it. so if the fence ones are similar it should take not only the
right frequency but also the proper tone/pulse combination to trigger the
collar... and unless you work 11m then it shouldn't be a problem unless
there is something wrong with it.
