Press Menu, scroll to select Waterfall, and press E. You can choose from Start Waterfall (using current settings), Start Preset Waterfall (predefined bands), or Start Custom Waterfall (user-defined bands).

The FFT Display shows a real-time graph of signal strength and background noise. The horizontal axis represents frequencies, and the vertical axis represents signal strength. A marker indicates the currently tuned frequency.

Press Function, then press the '9' key (labeled '9 DISP'). Select your preferred allocation (e.g., FFT: 50% / WF: 50%) and press E to confirm.

Press the Function key and then press the '0' key (marked 0 LVL). Turn the knob to adjust the gain level between 0 and 15, or select Auto.

At span sizes above 2.88 MHz, the scanner cannot receive a transmission unless the Hold soft key is pressed first.
