The RF specs range is listed and shown as .01 GHz to 10GHz in both the RF Browser and the RF Spectrum Analyzer and the specs on the website for this model and clearly shown in the user manual on page 27. Yet selecting the RF setting by pressing S2 in the browser shows the frequency settings ranges as 50-65 MHz to 2.4-2.5 GHz. It does not go above 2.5 GHz. What gives on this? Is the unit defective?
