This section provides you with background on how 
scanning works. You don’t really need to know all of this 
to use your scanner, but some background knowledge 
will help you get the most from your SC230. 

Your scanner’s memory is organized in an architecture 
called Dynamic Allocated Channel memory. This type of 
memory is organized differently and more efficiently than 
the bank/channel architecture used by traditional scanners. 
Dynamic Allocated design matches how radio systems 
actually work much more closely, making it easier to 
program and use your scanner and determine how much 
memory you have used and how much you have left.

Instead of being organized into separate banks and 
channels, your scanner’s memory is contained in a pool. 
You simply use as much memory as you need in the pool to 
store as many frequencies and alpha tags as you need. 
No memory space is wasted, and you can tell at a glance 
how much memory you have used and how much 
remains.

Unlike standard AM or FM radio stations, most two-way 
communications do not transmit continuously. Your 
SC230 scans programmed channels until it finds an 
active frequency, then stops on that frequency and 
remains on that channel as long as the transmission 
continues. When the transmission ends, the scanning 
cycle resumes until the scanner receives another 
transmission. 

The SC230 can search each of its 22 bands and up to 10 
banks together to find active frequencies. This is 
different from scanning because you are searching for 
frequencies that have not been programmed into the 
scanner. When you select frequency bands to search, the 
scanner searches for any active frequency within the
