Feature Highlights Feature Highlights General Close CallTM RF Capture Technology - you can set the scanner so it detects and provides information about nearby radio transmissions. See “Using the Close Call Feature” on Page 83 for more information. Dynamically Allocated Channel Memory - your scanner’s memory is organized so that it more closely matches how radio systems actually work, making it easier to program and use your scanner and determine how much memory you have used and how much you have left.
Dropout Delay – You can set whether the scanner pauses at the end of a transmission to wait for a reply. You can set the delay time for each system you scan, and while searching and using the Close Call feature. Attenuator – You can set the scanner’s attenuator to reduce the input strength of strong signals by about 18 dB received by the scanner. Repeater Reverse – You can set the scanner so it switches to the input frequency on a conventional repeater system or trunked system.
21 Bands – Includes 21 bands, with Aircraft and 800 MHz. Note: The scanner’s frequency coverage is not continuous and does not include the cellular telephone band. Trunk Tracking Trunk Tracker™ Operation – Follows conversations on analog Motorola, EDACS, EDACS SCAT, and LTR trunked radio systems. The scanner can scan both conventional and trunked systems at the same time.
Quick Search – Lets you search from the currently-tuned frequency if you are searching a conventional system, or from the currently-tuned trunk ID if you are searching a trunked system. Auto Store Frequency AutoStore – Automatically stores all active frequencies within a system you select. Talk Group ID AutoStore – Automatically stores all new talk group ID’s into a system you select.
PC Control – You can transfer programming data to and from your scanner and your personal computer, and control the scanner using a computer. This helps you find frequencies listed on the Internet and load them into the scanner. Clone Mode – You can clone all programmed data, including the contents of the scanner’s memory, menu settings, and other parameters from one BC246T scanner to another BC246T scanner.
are new to scanning or trunk tracking, be sure to read “Understanding Scanning” on Page 17 for a quick background on the technology. 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 “Setting Up Your Scanner” on Page 28 if you need any help doing this. Entering Text To enter a letter, turn the scroll control until the character you want appears, To enter a number, press a number key. To enter a decimal point, press .
Understanding Scanning This section provides you with background on how Understanding Scanning 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 BC246T. Understanding the Scanner’s Memory 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.
continues. When the transmission ends, the scanning cycle resumes until the scanner receives another transmission. What is Searching? The BC246T can search each of its 21 bands and up to 10 bands 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 lower and upper limits you specify.
might hear multiple communications at the same time. The stations might even interfere with each other to the point where it is impossible to clearly receive any of the stations. A scanner equipped with CTCSS and DCS (like your scanner) can code each received frequency with a specific CTCSS or DCS frequency. Then, when you receive multiple signals, you only hear the transmission with the CTCSS or DCS tone you programmed.

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.
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.
• The frequencies for many of the 800 MHz public safety systems are listed in the National Public Safety Trunked System Frequency Guide included with your BC246T scanner. Conventional scanning is a simple concept. You enter a frequency used by someone you want to monitor into your scanner’s memory. For example, the police in your area might transmit on 460.500 MHz, the fire department on 154.445 MHz, the highway department on 37.900 MHz, etc.
each time a user transmits. So, while on a conventional system queries, replies, and follow-ups are all on a single frequency, they could each be on completely different frequencies on a trunked system. This semi-random frequency assignment made monitoring such a system impossible prior to Uniden’s invention of the Trunktracking scanner. Not only does your BC246T scan channels like a conventional scanner, it actually follows the users of a trunked radio system.
can begin speaking. This all typically takes place in about a second...the person transmitting hears a beep from their radio when the channel is assigned and then it is OK to start talking. The systems in use are: Motorola Type I – the radios send the radio ID, the fleet and subfleet talk group ID to the control channel each time they transmit. To program a Type I system, you need to know the system’s fleet map. The most common fleet maps are included in “Preset Fleet Maps” on Page 105.
talk group will switch to the correct channel. To program an EDACS system in your scanner, you will need to know both the frequencies used by the system and the LCN for each frequency. Agency-Fleet-Subfleet – talk group ID’s for EDACS systems are assigned in a way that makes it easy to see at a glance the affiliation of the user. Each radio is assigned a 2-digit agency identifier from 00 – 15. For example, 01 might be used by the police, 02 by ambulance service, 03 by the fire department, and so on.
Users on an LTR system are assigned to specific talk groups, which are identified by the radio as six digit numbers. These numbers are in the form AHHUUU, where: A = Area code (0 or 1) H = Home repeater (01 through 20) U = User ID (000 through 254) When the scanner receives a transmission on a channel set to the LTR mode, it first decodes the LTR data included with the transmission. In the ID search mode, the scanner stops on the transmission and displays the talk group ID on the display.

Setting Up Your Scanner These guidelines will help you install and set up your new scanner: • If your scanner receives interference or electrical noise, move the scanner or its antenna away from the source. • 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.
Before installing batteries, set the switch in the battery compartment to match the type of batteries you will use. Select ALKALINE for non-rechargeable battery types and RECHARGEABLE for rechargeable battery types. See also “Using Rechargeable Batteries” on Page 31 when you use rechargeable batteries. 1. Remove the battery cover and set the battery switch. 2. Install 2 AA batteries, matching the polarity symbols (+ -).
3. Replace the cover. When flashes and the scanner beeps every 15 seconds, replace both batteries. Using Rechargeable Batteries You can also use two rechargeable batteries to power your scanner. Before you use rechargeable batteries, you must charge them. The scanner has a built-in circuit that lets you recharge batteries while they are in the scanner.
Before you use rechargeable batteries for the first time, charge them for 14 hours to bring them to a full charge. Discharged batteries take about 14 hours to fully recharge. Using AC Power You can power the scanner using the supplied 6V, 500 mA AC adapter. To use the scanner on AC power, plug the AC adapter into a standard AC outlet.
Connecting an Earphone/Headphone For private listening, you can plug a 1/8-inch (3.5 mm) mini-plug earphone or headphones (not supplied) into the headphone jack on top of your scanner. This automatically disconnects the internal speaker. Connecting an Extension Speaker In a noisy area, an optional amplified extension speaker, positioned in the right place, might provide more comfortable listening. Plug the speaker cable's 1/8-inch (3.5-mm) mini-plug into your scanner's jack.

Using Weather Alert (SAME) Using Weather Alert (SAME) Your scanner has been primarily designed to be a radio scanner. While it incorporates weather alert as one of its features, we strongly recommend that you not use the scanner as your sole means for receiving emergency alerts. Your local electronics retailer carries several weather radios specifically designed for this function.
Menu WX Operation E Weather Alert This setting determines which types of signals will trigger an alert. Select your setting, then press E. Alert Only - the scanner alerts when it detects the 1050 Hz tone that accompanies all weather alerts. ALL FIPS - the scanner alerts and displays information about the weather alert when it receives any FIPS code (see “Programming a SAME Group” on Page 92).
For example, Tarrant County in Texas is assigned to FIPS code 048439. 0 indicates the entire county 48 indicates the state of Texas 439 indicates Tarrant County To get the FIPS code for your county, visit the National Weather Service web site at http://www.nws.noaa.gov and search for “FIPS Listing”. Menu PrograM SAME WX Operation E E SELECT SAME select the SAME group to edit E Edit Name - enter the name you want to assign to the SAME group you selected.
Care and Maintenance Care and Maintenance • Turn the scanner off before disconnecting the power. General Use • Always write down the programmed frequencies in the event of memory loss. • If memory is lost, simply reprogram each channel. • Always press each button firmly until you hear the entry tone for that key entry. Location • Do not use the scanner in high-moisture environments such as the kitchen or bathroom. • Avoid placing the unit in direct sunlight or near heating elements or vents.
Repairs Do not attempt any repair. The scanner contains no user serviceable parts. Contact the Uniden Customer Service Center or take it to a qualified repair technician.

User Defined Fleet Maps Type I Programming Information When a Type I system is designed, the address information for all the ID’s is divided into 8 equal sized blocks, numbered 0–7. When you program your scanner to track a Type I system, you must select a size code for each of these blocks. When you have assigned a size code to all 8 blocks, you’ll have defined the fleet map for the system you are tracking. Each size code determines the number of fleets, subfleets, and ID’s each block will have.
of the replies to the conversations with ID’s assigned to the block you just programmed, then you’ve probably selected the right size code and can work on the next block of the map. Finally, for most public safety systems there are some size codes which are more common. S-3 and S-4 are probably the most common, followed by S-10, S-11, and S-12. Size Code Restrictions If you select size code S-12, S-13, or S-14, there are some restrictions as to which blocks can be used for these codes.
Collecting Information Getting your scanner programmed and scanning takes a few steps. This help guides you through these steps that will make it easier for you to start scanning. 1. Collect information about the system(s) you want to monitor. Do you want to listen to your local police and fire departments? How about the highway patrol, ambulance service, and aircraft? You might even want to listen to your local utility company as they track down a break in electrical service in your area.
Planning out help locally for the systems you want to scan by visiting the forums section of http://www.radioreference.com/forums. • Before you start to program your scanner, decide how you want to organize the frequencies you want to scan. For example, some areas are best organized by geographic location (east, north, south, west, central, etc), while others are best organized by agency (police, sheriff, ambulance, fire, etc.).
