What I've done is set up a special favorites group (69 for me). In this favorite group there are 9 conventional random freqs with each of the 9 frequencies setup with one of the nine alert tones. So I press 69, enter, hold. Now I rotate the top knob and able to hear each if the 9 alert tones. This comes in handy.
Favorite group 69 contains all the 9 alert tones, all the LED alert lights (constant, fast flash, slow flash). Also in this group, I list my different batteries used in the scanner and approx run times vs battery voltage. Also in this group, I list all the 7 weather NOAA channels and where the broadcast stations are.
So favorite group 69 is strictly an information group. It is NEVER scanned.
This can, of course, be done with the X96 and X36 scanners.
