You can use the BC75XLT to monitor police and fire departments (including rescue and paramedics), NOAA weather transmissions, business/industrial radio, utilities, marine and amateur (ham radio) bands, and air band transmissions. Of course, scanning the 32,000 available frequencies can be time-consuming and frustrating, which is why Uniden added such functions as Close Call capture technology, which instantly tunes to signals from nearby transmitters to help you detect and identify local signals, and a comprehensive memory that holds up to 300 programmed channels. Receives conventional channels on the following frequencies: (25-54 MHz) (108 - 174 MHz) (406 - 512 MHz) To program the unit: Push Hold. This should bring up the first available channel, it should show B:1 Channel 1 and 000.000. To program your frequency in you will push in the Orange Function key and then let go. Immediately push in the E button and let go. You will then see a black box with PGM in it in the top right corner of screen, this means you are in program mode. Type in your frequency including the decimal point, when finished push in the E key and let go. This will enter in the frequency. To enter in another frequency turn the knob at the top right one click to the right and this will bring you to the next available channel. Follow step 5 and on. When finished entering in all of your frequencies you may hit scan. The scanner will now begin scanning your frequencies.
