Understanding Scanning UThnisdseercstiotan nprdoivnidgesSycouanwinthinbagckground 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 BC92XLT. What is Scanning? Unlike standard AM or FM radio stations, most twoway communications do not transmit continuously. Your BC92XLT 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. What is Searching? The BC92XLT can search for 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 lower and upper limits you specify. When the scanner finds an active frequency, it stops on that frequency as long as the transmission lasts. If you think the frequency is interesting, you can program it into one of the banks. If not, you can continue to search. Conventional Scanning Conventional scanning is a relatively simple concept. Each group of users in a conventional system is assigned a single frequency (for simplex systems) or two frequencies (for repeater systems). Any time one of them transmits, their transmission always goes out on the same frequency. Up until the late 1980's Understanding Scanning 14

1. Turn Squelch fully counterclockwise.	33
2. Press and hold for about 2 seconds to turn the scanner on, then turn Volume clockwise until you hear a hissing sound.	33
3. If the scanner is scanning, press Hold to stop scanning, then turn Squelch clockwise until the hissing stops.	33
Storing Known Frequencies Into Channels	33
1. Press Hold. Then enter the channel number where you want to store a frequency, then press Func and Pgm. The channel number appears.	33
2. Use the number keys and to enter the frequency (including the decimal point) you want to store.	33
3. Press E to store the frequency into the channel.	33
4. To program the next channel in sequence, press E then repeat Steps 2 and 3.	34
Searching For and Temporarily Storing Active Frequencies	34
1. Press Func and Pgm during service search or service search hold mode. The frequency and the lowest blank channel alternately appear.	35
2. Press E to store the frequency into the blank channel. If you want to select another channel, press Func + or Func + before you press E. You can also use the 0-9 key to select the bank.	35
