2 Operating
Operating the direction finder is deliberately very simple with its clearly arranged layout. Except the upper page
rotary switch and the ON/OFF pushbutton, the function of the operating elements always depends on the active
page. All relevant adjustments can be controlled on the display. Figure 1 shows the general layout of the Display
Control Unit’s surface.
