I just got my scanner today and have the frequencies programmed that I want to use. So far I am only using 2 banks but anticipate using up to 3. On the screen it says BANK 2 at the top. The bottom line reflects 1 2 (which is flashing) 3 4 5 6 8 9 0. What does this bottom line mean? I feel like the fact that it says BANK 2 at the top means that it is only scanning bank 2. At most I will want it to scan banks 1, 2 and 3. Can someone put this in simple terms for me how to ensure that I am actually scanning all three of these banks? The instruction book is not all that helpful with this. Thank you!
