11 Feature Highlights Feature HighlightsClose CallTM RF Capture Technology - you can set the scanner so it detects and provides information about nearby radio transmissions. See “Close Call TM RF Capture Technology” on Page 37 for more information. Pager Screen - lets you set the scanner so it does not detect pager frequencies during Close Call search. Chain Search - lets you enter personal search bands in 10 locations and search all locations in a chain of frequency bands. Triple-Conversion Circuitry - virtually eliminates any interference from IF (intermediate frequency) images, so you hear only the selected frequency. Channel-Storage Banks - the scanner has 10 banks. You can store up to 20 frequencies into each bank (for a total of 200 frequencies), so you can more easily identify calls. Two-Second Scan Delay - delays scanning for about 2 seconds before moving to another channel, so you can hear more replies that are made on the same channel. Lock-Out Function - lets you set your scanner to skip over specified channels or frequencies when scanning or searching. Priority Channels - lets you program one channel in each bank (10 in all) and then have the scanner check that channel every 2 seconds while it scans the bank, so you do not miss transmissions on those channels. Six Service Banks - frequencies are preset in separate police, Fire/emergency, aircraft, ham, marine, and weather banks, to make it easy to locate specific types of calls.

12 Feature Highlights Key Lock - lets you lock the scanners keys to help prevent accidental changes to the scanners programming. Direct Access - lets you directly access any channel. Display Backlight - makes the scanner easy to read in low-light situations. Flexible Antenna with BNC Connector - provides adequate reception in strong signal areas and is designed to help prevent antenna breakage. Or, you can connect an external antenna for better reception. Memory Backup - keeps the frequencies stored in memory for an extended time if the scanner loses power. Two Power Options - let you power the scanner using internal batteries or external AC power using the included AC adapter. Key Confirmation Tones - the scanner sounds a tone when you perform an operation correctly, and an error tone if you make an error. Battery Low Alert - warns you when battery power gets low. About This Manual The screen displays used in this manual are representations of what might appear when you use your scanner. Since what you see depends on the frequencies for your area and the settings you select, you might notice some differences between what is in this manual and what appears on your scanner.

13 Feature Highlights To 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. BC92XLT Paper OM.fm Page 13 Tuesday, August 24, 2004 3:56 PM
14 Understanding Scanning Understanding 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 BC92XLT. What is Scanning? Unlike standard AM or FM radio stations, most two- way 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 BC92XLT Paper OM.fm Page 14 Tuesday, August 24, 2004 3:56 PM
15 Understanding Scanning this 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 Operation Simplex 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 Operation Repeater 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 BC92XLT Paper OM.fm Page 15 Tuesday, August 24, 2004 3:56 PM
16 Understanding Scanning listen 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 Information By 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 Internet The 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 Internets premier source for user-supported radio system information. •http://www.bearcat1.com - frequency information from National Communications.

19 Setting Up Your Scanner These guidelines will help you install and use your new scanner: • If your scanner receives interference or electrical noise, move the scanner or its antenna away from the source. You might also try changing the height or angle of the telescoping antenna. • To improve the scanner’s reception, use an optional external antenna designed for multi- band coverage. (You can purchase this type of antenna at a local electronics store). If the optional antenna has no cable, use 50-70 ohm coaxial cable for lead-in. A mating plug might be necessary for the optional antennas. • Use an optional mono earphone or mono headset with proper impedance for private listening. Read the precautions on the inside front cover of this Owners Manual. • Do not use the scanner in high-moisture environments such as the kitchen or bathroom. • Avoid placing the scanner in direct sunlight or near heating elements or vents. Using Internal Batteries You can power your scanner using two alkaline or rechargeable AA batteries (not supplied). Using Non-Rechargeable Batteries 1. Make sure the power is turned off. 2. Slide the battery compartment cover. 3. Before you install alkaline or any other non- rechargeable batteries, use a pointed object such as a ballpoint pen to set REG. ALK. BATT./ NI-MH BATT. inside the compartment to REG. ALK. BATT.. Setting Up Your Scanner BC92XLT Paper OM.fm Page 19 Tuesday, August 24, 2004 3:56 PM
20 Setting Up Your Scanner WARNING! Set REG. ALK. BATT./NI-MH BATT. to NI-MH BATT. only if you are using rechargeable batteries. Never attempt to recharge non-rechargeable batteries. Non-rechargeable batteries can get hot or burst if you try to recharge them. 4. Install two batteries in the compartment as indicated by the polarity symbols (+ and -) marked inside.
