Like Dragonball said, look at the scanner screen. If you see S0 then astericks all the way across the screen, you have deselected items attached to your quick keys. If you press the numbers 1-0, thats 1 thru 0, the numbers and you scanning should reappear. So if you want to scan alittle buy not a whole lot, temporarily asterick all numbers, then select only the numbers you want. The numbers assignments are a lengthy read. There are system keys, group keys, quick keys, and number tags. Each restricts something in your scanner to bring things that you are interested in to the forefront. Another trick, once you are scanning, is press hold on a frequency of interest. Then press hold again FOR ABOUT 2 SECONDS, you hear a double beep. Now you will scan only that system,
