While transmitting on 80 meters after a while it starts audible warning, very loud. I called the company tech support line and they did not have any solution. As an experiment I plugged the detector into a two wire extension cord and wrapped the extension around a #31 mix snap-on, then tested and it did not go off. The tech support said not to use an extension cable with the detector.

with are for vessel entry.
