7 Setup Connecting an Antenna You must install an antenna before you can operate the scanner. You have been provided a standard telescopic antenna that works well with this scanner, but you may want to purchases another type to increase the range. To connect the telescopic antenna, simply connect it to the BNC type ANT. connector on the rear of the scanner. You can purchase a variety of scanner antennas for both mobile and base station available at a local electronics store. Choose the one that best meets your needs. When deciding on a mobile or base station antenna and its location, consider these points. • The antenna should be as high as possible on a vehicle or a house. • The antenna and its cable should be as far as possible from sources of electrical noise (ignition systems, gauges, and so on). • The antenna should be vertical for the best performance. Mounting an Antenna Once you choose an antenna, follow the mounting instructions supplied with the antenna. Then route the antenna cable to the scanner. The antenna connector on your scanner makes it easy to use the scanner with a variety of antennas, such as an external mobile antenna or an outdoor base station antenna. Always use 50 ohm coaxial cable, such as RG-58 or RG-8, to connect an outdoor antenna. For lengths over 50 feet, use RG-8 low-loss dielectric coaxial cable. If your antenna’s cable does not have a BNC connector, you will also need a BNC adapter (available at a local electronics store). Follow the Installation instructions supplied with the antenna, route the antenna cable to the scanner, then connect it to the ANT.jack. Warning: Use extreme caution when you install or remove an outdoor antenna. If the antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches a power line, contact with the antenna, mast, cable, or guy wires can cause electrocution and death. Call the power company to remove the antenna. DO NOT attempt to do it yourself. Optional Antenna If you have chosen an optional mobile antenna, connect the antenna plug into the ANT connector on the rear of the scanner. (For more information on antenna installation, please refer to the instruction guide that came with your antenna.) BC780XLT1.qxd 10/08/2000 5:02 PM Page 7 8 Typical Mounting Methods The BC780XLT can be conveniently mounted on a table, bulkhead, overhead, or any other desired location (refer to figure below for typical mounting methods). Caution: Make sure there are no hidden electrical wires or other items behind the desired location before proceeding. Check that free access for mounting and cabling is available. Mounting the Scanner in Your Vehicle Before you mount the scanner, make sure you have all the necessary materials. Then confirm that the scanner fits your vehicle’s mounting area. This unit requires a mounting area of 2-3/8 inch high by 6-15/16 inch wide by 6 -9/16 inch deep (61 x 176.5 x 167 mm). Caution: Be sure to avoid obstructions behind the mounting surface. Follow these steps to mount the scanner in your vehicle. 1. Choose a mounting location, then use the supplied mounting bracket as a template to mark the positions for the mounting screw holes. 2. In the marked positions, drill holes slightly smaller than the supplied screws. 3. Attach the mounting bracket to the mounting location using the supplied screws and lock washers. 4. Attach the scanner to the mounting bracket using the supplied mounting knobs. 5. Connect the antenna’s cable to theANT. connector on the back of the scanner. Note: If the antenna cable’s connector does not fit in the ANT. connector, you might also need a Motorola-to-BNC antenna plug adapter (available at a local electronics store). • Table top mount• Bulkhead mount• Overhead mount BC780XLT1.qxd 10/08/2000 5:02 PM Page 8 9 Applying Power for Vehicle Installation You can power your scanner using either the supplied DC power cord or your vehicle’s cigarette lighter socket using DC cigarette lighter power cord. Caution: You must use a power source that supplies 13.8 V DC and delivers at least 700 mA. Your standard 12V car battery should be sufficient. The cord connector’s center tip must be set to positive and its plug must fit the scanner’s DC 13.8 V jack. The supplied DC power cord meets these specifications. Using a power cord that does not meet these specifications could damage the scanner or the adapter. • Always connect the adapter or DC power cord to the scanner before you connect it to the power source. When you finish, disconnect the adapter or DC power cord from the power source before you disconnect it from the scanner. • For added safety and to protect your scanner, disconnect the cable from your vehicle battery’s negative (-) terminal before you begin. Follow these steps to connect the supplied DC power cord. 1. Connect the power cord’s black wire to a chassis ground, such as a metal screw attached to a metal part of the vehicle’s frame. Be sure that the screw is not insulated from the frame by a plastic part. 2. Connect the power cord’s red wire (with in-line fuse) to a source of voltage that turns on and off with the ignition switch, such as a spare accessory terminal in your vehicle’s fuse box. 3. Insert the power cord’s barrel plug into the DC 13.8 V jack on the back of the scanner. 4. Reconnect the cable to the vehicle battery’s negative (-) terminal. To power the scanner from a vehicle’s 12 V power source (such as a cigarette-lighter socket), use the supplied cigarette-lighter adapter cord. To connect the supplied DC cigarette-lighter power cord, insert its barrel plug into the DC 13.8 Vjack on the back of the scanner, then plug the power cord into your vehicle’s cigarette lighter socket. Note: If you use a cigarette-lighter power cord and your vehicle’s engine is running, you might hear electrical noise from the engine while scanning. This is normal.

Programming Tips • Do not program a weather frequency into one of the channels, since weather channels transmit continuously. Use the Weather Search feature to select the weather information band. • Group similar services into a bank. For example, program police frequencies in channels 1 through 10 and fire/emergency into channels 51 through 60, and so on. • Put the frequency that you listen to the most or the most important frequency into a Priority channel. • To quickly program a series of channels, start with the lowest number channel. For example, when you are programming five new frequencies into Channels 4 through 8, start with Channel 4. After you finish programming a channel, press MANor HOLD/s to go to the next higher channel. • Write down your programmed channels and frequencies and put in a convenient place in case of accidental reprogramming. • If you want to download frequencies using the SmartScan feature, go to page 59 in this manual. • Frequencies are rounded off according to the step of each channel. • When you are overwriting a tagged channel with a new frequency, the previous alpha tag will be deleted. You must re-enter the alpha tag. • When programming frequencies, a 2 second delay is set automatically but can be changed in the Channel Data menu. Deleting a Stored Frequency To delete a stored frequency: a. Select a channel. b. Press 0. c. Then press E. Note: Channels with no frequencies are automatically locked out.

These systems are described here. vMOTOROLA - Including Type I, Type II, Hybrid, SMARTNET, and Privacy Plus. Motorola systems are widely used by public safety and business users. Most are on the 800 MHz band, and recent systems are appearing on other bands. vEDACS - Including "Wideband" 9600 baud, and "Narrowband" 4800 baud systems. "Wideband" systems are mostly on the 800 MHz band, and are used by public safety, utilities, and business users. Some systems are used on the VHF and UHF bands. "Narrowband" systems are used in the 935-940 MHz band, many by utilities. (See page 49) vLTR - These systems are mostly for business users, and found on the UHF, 800 and 900 MHz bands. (See page 52) For details on the operation and programming for all of these systems, see pages 36-58. When tracking these types of systems, remember these important points: • Your scanner defaults to monitor Motorola…

49 EDACS ® Reception EDACS ® Tracking TrunkTracker III now allows tracking of EDACS ® trunked systems. Until now these widely used systems have been almost impossible to monitor with a conventional scanner. With your TrunkTracker III listening to EDACS(s) is remarkably easy, and perhaps even easier than conventional scanning. EDACS systems use 'Transmission Trunking', which means that each transmission is assigned a new frequency. As the conversation moves through the system's frequencies, your TrunkTracker II automatically follows it. This chart shows a 30 second sample of EDACS transmissions. Eight different talkgroups are using the system as their transmissions switch between the thirteen system frequencies. Notice how the dotted line shows talkgroup 02-023 moving from channel to channel. Your BC780XLT can clearly and automatically follow this talkgroup, or any other, as you select. EDACS systems are organized in a logical way that keeps related talkgroups together. Your scanner is designed to take maximum advantage of this organization to make your scanning easy. It lets you zero in on just the part of the system you want to hear, whether it is an individual channel or an entire department or city. Programming EDACS System Frequencies When you program EDACS frequencies, it is critical that you store each one in the CORRECT LOCATION. By the nature of EDACS systems this is necessary for tracking. This often is not the frequency order, so you must be sure you have the right sequence. Sources for this information includewww.trunktracker.comand www.bc780xlt.com. BC780XLT1.qxd 10/08/2000 5:02 PM Page 49 50 An EDACS ® Trunked system This chart shows how talkgroups are organized within an EDACS system at the AGENCY level. The individual talkgroups cannot be shown at this scale because there are over 2000. However the chart can show the 16 Agencies in this example. The system is logical and easy to understand. EDACS systems are typically arranged in an outline structure. The system users are given blocks of talkgroups. Sizes vary but most large cities and other agencies have blocks of 128 channels. Smaller cities have only 64 or 32 channels. In this example, the County Sheriff is agency 01. The city of Sullivan is Agency 03. Adams Hill and Matthew Junction share Agency 08. Your scanner shows EDACS talkgroups in AFS (Agency-Fleet-Subfleet) format. This helps you see, at a glance, who you are monitoring. And with the partial-entry feature you can easily include nearby, related channels in the same Fleet or Agency. You can just as easily exclude entire unwanted Fleets and Agencies. When in Search mode, with the system frequencies programmed, and your scanner locked to the control channel, you can select a desired city by keying in the AGENCY part of the AFS talkgroup. For example, you can select the entire city of Sullivan with 4 key presses zero, three, , SRCH. When you hear an interesting talkgroup, capture it to your scan list by pressing Eduring the transmission. Or HOLD on it by pressing the HOLDkey. If you want to monitor the Sullivan Police Dispatch channel (which is talk group 03-062), press zero, three, , zero, six, two, HOLD. Your scanner can also work in DECIMAL format. This talkgroup in decimal format is 434. But decimal format does not give you any information about the system hierarchy. For example Sullivan, in decimal, uses channels from 384 to 511. This is not as easy to remember as Agency 03. But decimal is useful if you need to work from decimal talkgroup lists. BC780XLT1.qxd 10/08/2000 5:02 PM Page 50 51 Special EDACS ® Features AFS Partial Entry Feature AFS is Uniden's method of encoding EDACS talkgroups. AFS stands for 'Agency-Fleet-Subfleet'. AFS talkgroups are used in all EDACS reception -- in ID SEARCH, ID LOCKOUT and ID SCAN scanlists. The powerful AFS Partial Entry feature designed into the BC780XLT lets you use either a complete talkgroup code, or just the most significant part. This feature lets you expand or narrow searching and scanning to one of 4 levels. By entering only the desired part of an AFS talkgroup, you can select 2048 talkgroups, 128 talkgroups, 8 talkgroups, or a single talkgroup. For example, you could program every talkgroup in a police department with just 4 key presses. You can use the AFS Partial Entry feature anywhere that you need to specify EDACS talkgroup. Your BC780XLT can also enter or display EDACS talkgroups in decimal format (0-2047). Press MENU - TRUNK DATA, and for banks selected as EDACS banks, select Item 8, EDACS ID FORM and change it to Decimal. You can use this feature to translate decimal talkgroups lists to the much more powerful AFS format. Examples of how you might use AFS are shown above in the description of an EDACS trunked system, and elsewhere in this manual. It is very easy to use. Be sure to become familiar with AFS Partial Entry, and your scanning will become far more flexible and efficient. Emergency Call Alert Your BC780 alerts you when an EDACS Emergency transmission occurs. EDACS systems often provide users with an 'Emergency' button on their radios. Users in trouble can alert the dispatcher and other units and get priority access to the radio system. When a user activates Emergency mode your scanner will flash EMERGENCY during the entire transmission. At the beginning of each transmission it will sound a distinctive emergency alert tone three times. Patch Tracking The BC780 can follow EDACS patched talkgroups. EDACS systems sometimes bring several talkgroups together in a 'Patch'. A patch might be used by a police agency at night to provide a single channel with a single dispatcher for a wide area. A patch is created when a single, temporary talkgroup substitutes for the original talkgroups. While the patch is running, which may be for hours or days, the original talkgroups cease to be used. If you were monitoring one of these talkgroups, you might think there was no traffic, but in fact the talkgroup was operating …
