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...

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.

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....

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...

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...

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,...

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-...

the first block, then press 
E.­ The next available
block appears.

for each block you want to work with.
8. Press 
SRCH. The scanner exits the trunking pro-
gramming mode, tunes the data channel, then
