SCAN LISTS

When you program trunked frequencies into a bank (see “Storing Trunked Frequencies” on Page 41), your scanner sets up 5 scan lists into which you can store your favorite IDs. Each list can contain up to 10 IDs, so you can store a total of 50 IDs for each trunk tracking bank (250 IDs if you use all banks as trunking banks!). Scan lists help you organize trunking system users into categories. For example, you might use List 1 for police IDs, List 2 for fire department IDs, List 3 for emergency medical service IDs, and so on. Once IDs are stored in lists, you can scan them like you scan conventional channels. You can program IDs into scan lists manual- ly, during a search, or automatically.

Manually Storing IDs into Scan Lists

1.Select the trunking bank you want (see “Scanning a Trunked Bank” on Page 43).

2.After the scanner begins trunk tracking, press MAN. A number showing the current scan list appears steadily at the top of the display, and bars which show activity in other banks appear.

3.Press MAN then repeatedly press s or t to select the ID scan list location (shown at the top of the display) where you want to store an ID. Then, press PROG to select the ID you want to store.
