  • Page 9: Introduction

    Introduction Introduction Your BC246T scanner is a state-of-the-art scanner radio with TrunkTracking™ and automatic scanning capabili- ties. You can store frequencies such as police, fire/emergency, marine, air, amateur, and other communications into the scanner. You can carry it with you wherever you go, use it at home as a base unit, or install it in your vehicle as a mobile unit.

  • Page 16: Entering Text

    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.

  • Page 17: Understanding Scanning

    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.

  • Page 18: What Is Searching

    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.
  • Page 19 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.

  • Page 21: Repeater Operation

    Typical repeater systems provide coverage out to about a 25-mile radius from the repeater location. What is Trunk Tracking? Your BC246T is designed to track the following types of trunking systems. • Motorola Type I, Type II, Type IIi, hybrid, SMARTNET,...

  • Page 22: Trunked Scanning

    • 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.

  • Page 23: Types Of Trunking Systems

    Uniden’s invention of the Trunktracking scanner. Not only does your BC246T scan channels like a conven- tional scanner, it actually follows the users of a trunked radio system. Once you know a talk group’s ID, you won’t miss any of the action.

  • Page 24: Edacs Trunking

    Also, talk groups are assigned in an Agency-Fleet- Subfleet (AFS) hierarchy. Also, there is one variation of EDACS called SCAT that your BC246T can monitor. Logical Channel Numbers – each frequency used by the system is assigned an LCN. This information is pro- grammed into each user radio.

  • Page 25: Ltr Trunking

    Autonomous Trunking) systems operate on a single channel and alternate control data with analog voice traf- fic. While your BC246T cannot track ID’s in this system, it can eliminate the control data so that all you hear is the voice transmissions when you monitor this type of system.

  • Page 26: Where To Get More Information

    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...

  • Page 29: Using Internal Batteries

    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.
  • Page 30 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.

  • Page 31: Using Rechargeable Batteries

    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.

  • Page 32: Using Ac Power

    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.

  • Page 33: Connecting An Earphone/Headphone

    Connecting an Earphone/Headphone For private listening, you can plug a mini-plug earphone or headphones (not supplied) into the headphone jack on top of your scanner. This automati- cally 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 comfort- able listening.
