These scanners are both a blessing and a curse. They do lots of things and there are a couple of different ways to accomplish the same result. To get the most from your scanner requires remembering lots of things, which is the curse part.
It's definitely a learning curve, but one that can be mastered with time, practice and patience.
As mentioned above, number tags are "optional" shortcuts. Programming number tags is not essential to making a scanner do its thing. (Out of the nearly 175 systems I have programmed in my scanner, I only have number tags set up on one system the rest are blank).
