    							CTCSS Operation
    Your scanner is equipped with a Continuous Tone Control Squelch System (CTCSS) which allows
    squelch to open only when the tone you have programmed with a specific frequency is received
    along with a transmission. When using CTCSS, consider the following:
    You do not have to use CTCSS tones while scanning.
    You cannot enter CTCSS tones in the AM Air Band.

    							Searching for CTCSS Tones
    You can use the CTCSS Tone Search Mode to determine if the frequencies in your area are
    broadcast with associated tones. You may find frequencies which do not have a tone associated
    with them. This may be because CTCSS tones are not being transmitted or because digital
    encoded tones, sometimes called DCS, are used and your scanner does not recognize these.
    Using CTCSS Tone Search While Scanning
    1. Presss.
    2. To determine if a stored frequency has an
    associated CTCSS tone, press
    m
    when your scanner stops on a channel.
    3. Press and hold
    Kuntil you hear two
    short beeps.
    CTCSSdisplays and begins flashing, and
    the scanner starts searching for an
    associated CTCSS tone. All 38 tones are
    checked if the transmission is long
    enough. If there is a break before a tone
    is identified, then your scanner starts
    searching where it left off when the
    transmission begins again.
    If a CTCSS tone is found, the tone begins
    flashing in the display.
    4. Press
    eto program the tone with the
    frequency stored in the channel.
    5. Repeat Steps 1 – 4 to search for tones

    							Trunk Tracking
    YourBC895XLTis designed to track Motorola Type I, Type II, Type IIi, Hybrid,SMARTNET™, and
    PRIVACY PLUS™ analog trunking systems*, which are extensively used in 800 MHz communication
    systems. When tracking these types of systems, you may want to remember these important points:
    Your scanner defaults to monitor Type II systems; however, you can change this if the
    system in your area is different. (The types of systems are discussed below.)
    Your scanner cannot track an 800 MHz trunked system and scan frequencies in
    conventional mode at the same time.
    The frequencies for many of the 800 MHz public safety systems are listed in the
    TrunkTracker™: National Public Safety Trunked System Frequency Guideincluded with
    your
    BC895XLTscanner.
    *Motorola,SMARTNET, andPRIVACY PLUSare trademarks of Motorola Inc.
    Types of Trunking Systems
    Trunking systems divide a few frequencies among many different users, but the way that each
    system does this is slightly different. There are really two basic types which are important when
    using your
    TrunkTracker™scanner. These are usually referred to as Type I and Type II systems.
    One important distinction between these two systems is the amount of data transmitted by each
    radio when its push-to-talk button (PTT) is pressed. Every radio in a trunked system is assigned a
    unique ID so the central site computer can identify it when it’s used. Both Type I and Type II
    systems place radios (or radio users) into groups, called talk groups, and these talk groups are also
    assigned unique IDs. Some radios have access to only one talk group, while others have access to
    many talk groups. Which talk group(s) each radio can access is called the radio’s affiliation(s).
    In a Type II system, when someone uses their radio, only the radio ID is transmitted when PTT is
    pressed, whereas in a Type I system the radio ID and its current affiliation are both transmitted
    when PTT is pressed.
    Why the difference? Type II systems are slightly more advanced because the central computer
    maintains a database which is used to determine each radio’s affiliation(s). Changes to a Type II
    system are easier than Type I because the system manager only need update the database instead
    of reprogramming individual radios.
    Another difference between the systems is that Type I systems are arranged in a Fleet-Subfleet
    hierarchy. For example, it’s possible for a city using a Type I system to designate 4 Fleets, each
    with 8 Subfleets. Their fleets might be the Police Department, the Fire Department, Utilities, and
    Administration. The Police may decide to further divide their fleet into subfleets such as Dispatch,
    Tactical Operations, Detectives, North, South, East and West Side Patrols, and Supervisors. All the
    available police radios would then be assigned to one of the police subfleets. Determining the exact
    Fleet-Subfleet hierarchy for a particular area is referred to as Fleet Map Programming.
    The disadvantage of a Type I system is that when PTT is pressed, the brief burst of data must
    contain the radio’s ID and its Fleet and Subfleet. This is three times the amount of data a Type II
    system radio sends, and as a result Type I systems usually accommodate fewer users than Type II
    systems.
    Even though there are many Type II systems, Type I systems are still in use. There are also Hybrid
    systems which are a combination of both Type I and Type II. Your scanner defaults to monitor
    Type II systems, but it’s possible to select a Preprogrammed Fleet Map or create a Custom Fleet
    Map for your area.

    							Setting the Squelch
    Since Squelch is automatically adjusted in trunking mode, it isn’t necessary to manually adjust the
    squelch control while trunk tracking. However, the squelch setting you select before you begin trunk
    tracking can affect how fast your scanner acquires the data channel, and, in some instances, the
    squelch setting can prevent your scanner from acquiring the data channel at all.
    Set
    SQUELCHin this position before
    selecting a trunking bank.
    Note:You can change this recommended
    setting, if necessary, to provide better
    performance in your area.
    Programming Trunking Frequencies
    Before you start programming your scanner to track a trunked system, consider the following:
    You can only program one trunking system in each bank of your scanner.
    Trunking frequencies must be entered while in the Trunking Programming mode.
    If you’re in the Trunking Programming mode, you cannot select channels in other banks.
    For example, if you are programming Bank D, you can only select channels 91-120 with the
    Rotary Tuner or using the
    horikeys.
    The first step in tracking a trunked system is storing the frequencies in one of the 10 available banks
    in your scanner.
    1. Press and hold
    t.
    You will hear two beeps, andBANKand
    TRUNKwill begin to flash in the display.
    2. Choose the bank you want to trunk track.
    For example, press
    B.
    3. Use the keypad to enter a frequency for
    the trunked system.
    For example, enter856.2625, or enter a
    frequency of the system you’re going to
    track.
    Then press
    e.
    Note:To clear a mistake while entering a frequency, press.twice, and start over.
