I can only speak to the EZScan methods. Whether Channels or TGs, use standard Windows methods to "highlight" those Channels or TGs that you want to assign BacklightLED info. Left Click in the "highlighted " area in the BKLT/LED column. You should get a pop-up window (Backlight/LED Configuration).
There are too many options available here to go into detail. A basically unlimited range of combinations of solid/flashing multi color and multi dwell (duration) options to suit one's personal taste. Experiment with the settings, DON"T FORGET TO HIT "SET", send to the scanner, and critique your choices.
Repeat until you like the results. I wouldn't be surprised if a Morse Code wizard could come up with a color/flash combo that identified the particular Channel/TG (three or four letter code).
