Uniden BC245XLT manual Fleet Map Size Codes

If you don’t already know the size codes used, you’ll have to guess at them. But since you don’t have to figure out all the blocks at once, this isn’t as hard as it seems. Select a

size code for a block, and then press . Now listen to the communications. If you decide you are receiving most of the replies to the conversations with IDs assigned to the block you just programmed, then you’ve probably selected the right size code and can work on the next block of the map.

Finally, for most public safety systems there are some size codes which are more common. S-3 and S-4 are probably the most common, followed by S-10, S-11, and S-12.
