The smaller concentric knob on the Nav side of the KX-165 has a PULL RAD label on it. When this knob is pulled, a radial mode for the KX-165 is enabled where the right hand window of the NAV display indicates the bearing FROM a station. In addition, a digital warning flag is activated when weak signals are present. Also, when an ILS frequency is selected, the digital flag is displayed in the radial window.
