7The FCC Wants You To KnowThe FCC Wants You To KnowThis scanner has been tested and found to comply with the limits for a scanning receiver, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This scanner generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.However, there is no guarantee that interference will not occur in a particular installation. If this scanner does cause harmful interference to radio ortelevision reception, which can be determined by turning the scanner on and off, you are encouraged to try to correct the interference by one or more of the following measures:• Reorient or relocate the receiving antenna• Increase the separation between the scanner and the receiverThis device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1) This device may not cause harmful interference, and 2) this device must accept any interference received, including interference that may cause undesired operation.Scanning LegallyYour scanner covers frequencies used by many different groups, including police and fire departments, ambulance services, government agencies, private companies, amateur radio services, military operations, pager services, and wireline (telephone and telegraph) service providers. It is legal to listen to almost every transmission your scanner can receive. The FCC Wants You To KnowBC72 Paper OM.fm Page 7 Monday, October 25, 2004 3:11 PM
8The FCC Wants You To KnowHowever, there are some transmissions that you should never intentionally listen to. These include: • Telephone conversations (cellular, cordless, or other private means of telephone signal transmission) • Pager transmissions • Any scrambled or encrypted transmissions According to the Electronic Communications Privacy Act (ECPA), you are subject to fines and possible imprisonment for intentionally listening to, using, or divulging the contents of such a conversation unless you have the consent of a party to the conversation (unless such activity is otherwise illegal). This scanner has been designed to prevent the reception of cellular telephone transmissions and the decoding of scrambled transmissions. This is done to comply with the legal requirement that scanners be manufactured so they are not easy to modify to pick up these transmissions. Do not open your scanner’s case to make any modifications that could allow it to pick up transmissions that are illegal to monitor. Modifying or tampering with your scanner’s internal components or using it in a way other than as described in this manual could invalidate your warranty and void your FCC authorization to operate it.In some areas, mobile use of this scanner is unlawful or requires a permit. Check the laws in your area. It is also illegal in many areas (and a bad idea everywhere) to interfere with the duties of public safety officials by traveling to the scene of anincident without authorization.

13Feature HighlightsTo get the most from this manual, review the contents to become familiar with the basic functions available. If you are new to scanning, be sure to read “Understanding Scanning” on Page 14 for a quick background on the technology behind the hobby. The first thing you’ll need to do is install batteries in the scanner. Then you need to connect the included antenna to the scanner. See “Using Internal Batteries” on Page 19 and “Connecting the Antenna” on Page 23 if you need any help doing this.BC72 Paper OM.fm Page 13 Monday, October 25, 2004 3:11 PM
14Understanding ScanningUnderstanding ScanningThis 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 BC72XLT.What is Scanning?Unlike standard AM or FM radio stations, most two-way communications do not transmit continuously. Your BC72XLT 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 BC72XLT 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 ScanningConventional 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 ScanningBC72 Paper OM.fm Page 14 Monday, October 25, 2004 3:11 PM
15Understanding Scanningthis was the primary way that radio systems operated. Even today, there are many 2-way radio users who operate using a conventional system: •Aircraft • Amateur radio • FRS/GMRS users • Broadcast AM/FM/TV stations • Many business radio users When you want to store a conventional system, all you need to know is the frequencies they operate on. When you are scanning a conventional system, the scanner stops very briefly on each channel to see if there is activity. If there isn’t, the scanner quickly moves to the next channel. If there is, then the scanner pauses on the transmission until it is over. Simplex OperationSimplex systems use a single frequency for both transmit and receive. Most radios using this type of operation are limited to line-of-sight operation. This type of radio is frequently used at construction job sites, and with inexpensive consumer radios such as GMRS/FRS radios. The range is typically 1-8 miles, depending upon the terrain and many other factors. Repeater OperationRepeater systems use two frequencies: one transmits from the radio to a central repeater; the other transmits from the repeater to other radios in the system. With a repeater-based system, the repeater is located on top of a tall building or on a radio tower that provides great visibility to the area of operation. When a user transmits (on an input frequency), the signal is picked up by the repeater and retransmitted (on an output frequency). The user’s radios always BC72 Paper OM.fm Page 15 Monday, October 25, 2004 3:11 PM
16Understanding Scanninglisten for activity on the output frequency and transmit on the input frequency. Since the repeater is located very high, there is a very large line of sight. Typical repeater systems provide coverage out to about a 25-mile radius from the repeater location. Where To Obtain More InformationBy itself, this manual really only provides part of what you need to know to have fun scanning – how to program and use the scanner. The included conventional frequency guide will give you a good head start on the other part of what you need to know – what frequencies have interesting content. Information On The InternetThe Internet is a great source for current frequencies and information about scanning. Many web sites have lists of frequencies for your area. You can use a search engine to find and use them. Make a list of the agencies you want to listen to, then look up the frequencies and systems used by those agencies. Here are a few useful sites:•http://www.scannermaster.com * - frequency resources and home of Police Call.You can also call them at 1 800 SCANNER (hours are from 9:00 a.m. to 5:30 p.m. Eastern Time Monday through Friday).•http://www.radioreference.com * - the Internet's premier source for user-supported radio system information.•http://www.bearcat1.com - frequency information from National Communications.BC72 Paper OM.fm Page 16 Monday, October 25, 2004 3:11 PM

26About Your ScannerAbout Your ScannerWe use a few simple terms in this manual to explain the features of the scanner. Familiarize yourself with these terms and the scanner's features, and you can put the scanner to work for you right away. Simply determine the type of communications you want to receive, then set the scanner to scan those communications.A frequency, expressed in kHz or MHz, is the tuning location of a station. To find active frequencies, you use the search function or refer to a frequency reference.Besides searching within a selected frequency range, you can also search your scanner's service banks. Service banks are preset groups of frequencies categorized by the type of services that use those frequencies. For example, many amateur radio frequencies are located in the HAM service bank.When you search and find a desired frequency, you can store it into a programmable memory location called a channel. Channels are grouped into channel-storage banks. The scanner has 10 channel-storage banks and each bank has 10 channels. You can scan the channel-storage banks to see if there is activity on the frequencies stored there.About Your ScannerBC72 Paper OM.fm Page 26 Monday, October 25, 2004 3:11 PM

32About Your ScannerUnderstanding BanksService BanksThe scanner is preprogrammed with all the frequencies allocated to the weather, ham, marine, aircraft, police, and fire services.Channel-Storage BanksTo make it easier to identify and select the channels you want to listen to, the 100 channels are divided into 10 channel-storage banks. Each bank has 10 channels. Use each channel-storage bank to group frequencies, such as those for the police department, fire department, ambulance services, or aircraft.For example, the police department might use four frequencies in your town while the fire department uses an additional four. You could program the four police frequencies starting with Channel 1 (the first channel in bank 1), and program the fire department frequencies starting with Channel 11 (the first channel in bank 2).BC72 Paper OM.fm Page 32 Monday, October 25, 2004 3:11 PM

37Special FeaturesSpecial FeaturesClose CallTM RF Capture TechnologyYour scanner's Close Call feature lets you set the scanner so it detects then displays the frequency of a nearby strong radio transmission. Close Call RF capture works great for finding frequencies at venues such as malls and sporting events. You can set the scanner so Close Call detection works "in the background" while you are scanning other frequencies, turn off normal scanning while Close Call is working, or turn off the Close Call feature and use the scanner normally. You can set the scanner so it alerts you when the Close Call feature detects a frequency. You can also set the frequency band where you want the scanner to look for transmissions.Unlike searching, which requires the scanner to tune to a frequency to check for a transmission, Close Call RF capture directly detects the presence of a strong, nearby signal and instantly tunes to the source’s frequency.Notes: • Close Call RF capture works well for locating the source of strong local transmissions such as mobile and handheld two-way radios in areas with no other strong transmission sources. However, if you are in an area with many transmission sources (such as pager radiotransmitters, multi-use radio towers, traffic control devices, etc.), Close Call RF capture might not find the transmission you are searching for, or it might find a transmission other than the one you are searching for.• Close Call RF capture cannot detect satellite dishes or any transmitter with a frequency above or below the frequency ranges listed under “Setting the Close Call Options” on Page 38.Special FeaturesBC72 Paper OM.fm Page 37 Monday, October 25, 2004 3:11 PM
38Special Features• Close Call works better with some types of transmissions than others.
