I really dont understand how the scan list work.
The radio can have up to 1852 scanable objects (if they are all conventional frequencies). Any of those objects may be placed in any (or all) of the 22 scan lists that are available in the scanner.
Think of a scan list as a group of objects (Conventional Frequencies, talkgroups, etc) that are similar in nature. You could use scan list 1 as Police, scan list 2 as Fire, and so on. You can then take all police talkgroups and conventional frequencies in the scanner and add them to scan list 1, and all fire frequencies and talkgroups and add them to scan list 2. It doesn't matter what type or system they are a part of.
You could also group them by city or area, and you could even create a "scan all" scan list by adding all of the objects into a single scan list in addition to the ones listed above.
On my scanner, I have the 8CALL and 8TAC frequencies as members of almost all of my scan lists. I only had to enter them in the scanner once, but they were added to multiple scan lists, so if any of those are enabled, I get those frequencies.
Once you have the scan lists set up, the operation of the scanner is similar to the older banked scanners where you turn a scan list on by pressing the corresponding number, or for scan lists 11-20, pressing the FUNC key and then the number if the ones place.
