41 SCAN LISTS When you program trunked frequencies into a bank (see “Programming Trunked Frequencies” on Page 34), 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 (500 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 manually, 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 36). 2. After the scanner begins trunk tracking, press MAN- UAL . A bar appears at the top of the display, showing the current scan list. 3. Repeatedly press s or t to select the scan list loca- tion (shown at the top of the display) you want to program. 20-520.fm Page 41 Wednesday, August 4, 1999 3:06 PM
42 4. Enter the Type II ID you want to store, then press E. Or, to enter a Type I ID: a. Use the number keys to enter the block number and the fleet number, then press •. b. Enter the subfleet number, then press E. Note: To clear a mistake while entering an ID, press • twice, then start over at Step 1. 5. Repeatedly press MANUAL or s to select the next scan list location you want to program. Then repeat Step 4 to enter another ID. Storing IDs Into Scan Lists While Search- ing Follow these steps to select a scan list location and store an ID during a search. 1. When your scanner stops on an ID you want to store, press PRI. The currently selected scan list memory location flashes. 2. Press E to store the ID in the selected scan list memory location. Or, repeatedly press s or t to select the scan list memory location you want, then press E. 3. Press SRCH to resume searching. Automatically Storing an ID in a Scan List Location Follow these steps to store an ID in the first empty scan list location during a search. 1. When your scanner stops on an ID you want to store, press E. The scanner stores the ID in the dis- played scan list location. 20-520.fm Page 42 Wednesday, August 4, 1999 3:06 PM
43 2. Press SRCH to resume searching. Deleting a Stored ID 1. Repeatedly press s or t to select the scan list loca- tion (shown at the top of the display) you want to delete. 2. Press 0 then E. SCANNING THE SCAN LISTS Press SCAN to begin scanning the lists you have pro- grammed. Note: If you havent programmed any IDs, SCAN scrolls on the display but your scanner does not stop on an ac- tive conversation. To remove a scan list from active scanning, use the number keys to enter the scan list’s number. The scan 20-520.fm Page 43 Wednesday, August 4, 1999 3:06 PM
44 list indicator turns off, and the IDs in that list are not scanned. Note: One scan list must always be active. If you try to re- move all the scan lists, the first scan list will stay active. To restore a scan list to active scanning, use the number keys to enter its number again. Press SRCH to return to the scanner’s previous function. To alternate the display between the channel activity in- dicators and the scan list indicators, press PRI. SCANNING TYPE I AND HYBRID TRUNKED SYSTEMS Your PRO-90 is set to scan Type II user IDs by default. When you scan trunked frequencies, each Type II user ID you see appears as an even number without a dash (such as 2160). Your PRO-90 can also scan Type I trunked systems. Each Type I ID appears as a three- or four-digit number, followed by a hyphen, followed by a one- or two-digit number (such as 200-14). If you notice a mix of odd- and even-user IDs (such as 6477, 2160, 6481, 6144, and 1167), then you are probably monitor- ing either a Type I or hybrid (a combination of Type I and Type 2 user IDs) system (see “Types of Trunked Sys- tems” on Page 32). You might also notice that you are missing responses when you hold on an active ID. Unlike Type II systems, Type I and hybrid systems require a fleet map that sets specific fleet-subfleet parameters. It is easy to select a fleet map to scan; what is not always easy is selecting or programming a map that is being used in your particular area. When a Type I system is designed, the address informa- tion for all its user IDs is divided into 8 equal-size blocks, numbered 0–7, and each block is assigned a size code. 20-520.fm Page 44 Wednesday, August 4, 1999 3:06 PM
45 When you set up your scanner to track a Type I system, you must choose a size code for each block. When you have chosen a size code for all 8 blocks, you will have duplicated the fleet map for the system you are tracking. If you have chosen correctly, you will be able to track transmissions in that system. Each size code defines the number of fleets, subfleets, and IDs each block has. For example, you can see in the following table that a size code of S-4 has one fleet, which is divided into 16 separate subfleets, and it has a total of 512 individual IDs. Each ID in the block is unique. The left-most digit is the block number in the ID. The next two digits identify which fleet is active, and the last digit(s) (after the hyphen) identifies the subfleet. The size codes selected by a Type I system designer de- pend on the specific needs of the systems users. Some organizations might want many subfleets with only a few radios each, while another organization might want only a few subfleets, with many radios each.

46 systems, you must select or program a fleet map with the same size code assignments as the trunked system. If you do this accurately, you will track all the fleet and subfleet combinations used by the system. In other words, you will hear complete communications while monitoring a trunked system. Note: Preset fleet maps might be available at www.trunkscanner.com. If you do not already know the size codes used, you will have to guess them. But since you do not have to figure out all the blocks at once, this is not as hard as it seems. Select a size code for a block, then press SRCH. Now lis- ten to the communications. If you decide you are receiv- ing most of the replies to the conversations with IDs assigned to the block you just programmed, then you have probably selected the right size code and can work on the next block of the map. There are 16 preset fleet maps to choose from, and it is best to start with these when setting up a Type I or hy- brid trunk tracking bank. If none of the following preset fleet maps allow you to follow complete conversations, then you probably need to program your own fleet map (see “Programming a Fleet Map” on Page 49).

49 2. Press DATA. 3. Repeatedly press s or t to select E1, then press DATA again. 4. Repeatedly press s or t to select the name of the map you want (such as P7), then press E. The scanner then searches for transmissions using the preset map you chose. Note: When the scanner searches for transmissions, you see Type I fleet and subfleet IDs such as 100-12, 100-9, 000-12, or 400-8. How do you know if the preset map you selected is cor- rect? Listen to see if you are following complete conver- sations. If not, try another preset map. Programming a Fleet Map 1. Select the bank where you want to program the fleet map by pressing a number key. 2. Press DATA. 3. Repeatedly press s or t until E1 appears, then press DATA. 4. Repeatedly press s or t until USr appears. 5. Press DATA. 20-520.fm Page 49 Wednesday, August 4, 1999 3:06 PM
506. Repeatedly press s or t to select the size code for the first block, then press E. The next available block appears. 7. Repeat Step 6 until you have selected a size code for each block you want to work with. 8. Press SRCH. The scanner exits the trunking pro- gramming mode, tunes the data channel, then begins to search using the map you programmed. Note: If you select size code S-12, S-13, or S-14, these re- strictions apply: • S-12 can only be assigned to Blocks 0, 2, 4, or 6. • S-13 can only be assigned to Blocks 0 and 4. • S-14 can only be assigned to Block 0. Since these size codes require multiple blocks, you will be prompted for the next available block when program- ming a fleet map. For example, if you assign Block 0 as an S-12, the scanner prompts you for b2, the next block available, instead of b1. And if you assign Block 0 as an S-14, you would not see another prompt because it uses all available blocks. Programming a Hybrid System A hybrid system is simply a Type I system with some of its blocks designated as Type II blocks. To program a hybrid system, follow the steps listed in “Programming a Fleet Map” on Page 49. However, if you want a block to be Type II, select size code S-0 in Step 6. 20-520.fm Page 50 Wednesday, August 4, 1999 3:06 PM
