The radar, video plotter, sounder and chart systems are operated with the control unit. Ten
keys are labeled and they provide the function shown on their labels. The five soft keys
provide various functions according to current operating mode. The ENTER knob mainly
functions to register selections on the menu and adjust the EBL, VRM and gain. The
Trackball’s main function is to move the cursor across the screen. When you correctly
execute an operation, the unit generates a beep. Invalid operation causes the unit to emit
three beeps.
