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. If you have more questions about CTCSS, seeWhat is CTCSSon page 5. Programming a Channel with a CTCSS Tone 1. Select a channel you want to program. 2. Enter a frequency. a. Use your keypad to enter the frequency you want. b. Then press e. 3. Press K, and then presse. IfCTCSSMode is already selected, then only press e. 4. Enter a tone. a.

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 associated with other stored frequencies. SCAN MANUAL PRI TRUNK DATA L/O DELAY CTCSS 12 4 75 8 03 6 9 E 34
If you want to program tones for several stored frequencies, follow these steps: After you program a CTCSS tone with a stored frequency, the CTCSS Tone Search Mode is canceled. The CTCSSindicator remains on but does not flash. To activate the CTCSS Tone Search Mode again, press and hold Kuntil you hear two short beeps. If you decide to cancel the CTCSS Tone Search Mode while scanning, press and hold Kuntil you hear two short beeps and theCTCSSindicator turns off. You can select the CTCSS Search Mode before pressings. Simply, press and hold Kuntil theCTCSSindicator begins flashing, and then presss. When your scanner stops, the CTCSS Tone Search begins immediately. If a tone is found before the transmission ends, press eto program the tone with the frequency stored in the channel.

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. 38
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. SQUELCH VOLUME SCAN MANUAL PRI TRUNK DATA L/O DELAY CTCSS 12 4 75 8 03 6 9 E 39
If you enter a non-800 MHz trunked repeater output frequency, an error message displays for two seconds and then the scanner resets. 4. Press eithermorhto select the next channel in the bank. 5. Repeat steps 3 and 4 until all frequencies have been entered. 6. Press Sto begin searching the bank you’ve programmed. Note:You will see the frequencies quickly displaying as your scanner looks for the data channel which controls the system. Searching a Trunked Bank Before you Search a Trunked Bank with your scanner, consider the following: You can only trunk track one bank at a time. Usetto toggle between the conventional and the trunk tracking modes. Pressdwhile in the Trunk Tracking mode to review which bank is currently in use. The appropriate bank icon will flash at the top of the display for 5 seconds. If you have programmed frequencies for a trunked system in one or more of the 10 available banks and you are in conventional mode, follow these steps to begin trunk searching: 1. Press t. The bank indicators begin to flash. 2. Use the alpha keys to select the trunked bank you want. For example press B. Note:You will see the frequencies quickly displaying as your scanner looks for the data channel which controls the system. 40
