  • Page 24: Restore A Locked Out Channel

    Restore a Locked Out Channel Press Select a locked out channel. a. Enter the channel number. b. Then press again. Press to unlock the channel. Restore All Locked-Out Channels You can restore all locked-out channels in a bank only when a bank is selected for scan. If you have deselected a bank and you want to restore all of its locked-out channels using the steps below, you must press the number of the bank on your keypad.
  • Page 25: Priority Scan

    Press and hold for about two seconds. You will hear two beeps when all the channels have been restored.

  • Page 35: Trunk Tracking

    Trunk Tracking Your BC 235XLT Type II, Type IIi, Hybrid, analog trunking systems 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.
  • Page 36 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...
  • Page 37: Setting The Squelch

    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.
  • Page 38 The first step in tracking a trunked system is storing the frequencies in one of the 10 available banks in your scanner. Press and hold You will hear two beeps, and BANK and TRUNK will begin to flash in the display. Choose the bank you want to trunk track.
  • Page 39: Searching A Trunked Bank

    Press either to select the next channel in the bank. Repeat steps 3 and 4 until all frequencies have been entered. Press to 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.

  • Page 42: Id Lockout

    ID Lockout Like conventional scanning, it’s possible to lockout unwanted traffic. This is particularly important in trunked systems because in many areas water meters, door alarms, traffic signals, and other mechanical devices are assigned IDs just like other users. Also some departments scramble or encrypt their communications, and you may want to lock out these unintelligible broadcasts.
  • Page 43: Restore All Ids

    Restore all IDs To unlock all locked out IDs at once, follow these steps: Press and hold until you hear two short beeps. Press to unlock all the IDs at once. Note: If you unlock all the IDs, then the Scan List Memory mode displays.
  • Page 44: Channel Activity Indicators

    Hold Mode Press This is where the trunk tracking effect is really noticeable. You can hold a specific talk group, such as fire department on-scene operations, no matter which frequency the group uses. ID Monitor Mode If you press and hold beeps, you will select the ID Monitor mode.
  • Page 45 The indicator which remains on, even if when there is no traffic, represents the frequency being used as the data channel. If an indicator turns on and you don’t hear a conversation, then the channel is probably being used for a telephone interconnect call or a private call.
  • Page 46: Scan Lists

    Scan Lists Each bank of your bank or it can be a conventional scanning bank. When you designate a bank as a trunking bank, your scanner sets up 5 Scan Lists, which are simply lists used to store your favorite IDs. Each list can contain up to 10 IDs, so you can store a total of 50 IDs for each trunk tracking bank (500 if you use all banks as trunking banks!).
  • Page 47 Enter the Type II ID you want to store, and press —or— To enter a Type I ID: a. Enter the fleet number. b. Press c. Enter the subfleet number, and press Note: To clear a mistake while entering an ID, press twice, and start over.
  • Page 48 To restore a Scan List to active scanning, press its number again. Press to return to Trunk Tracking Search mode. To alternate your display between the trunking repeater indicators and the Scan List indicators, press Programming Scan Lists During Search To select a Scan List location and store an ID during Search mode, follow these steps: When your scanner...
  • Page 49: Deleting A Stored Id

    To let your scanner automatically store an ID in an available Scan List location, follow these steps: Press when your scanner stops on an ID you want to store. Press to return to Trunk Tracking Search mode. Deleting a Stored ID To delete a stored ID: a.
  • Page 50: Fleet Map Programming

    Fleet Map Programming If you have programmed a trunk tracking bank and select , you will see user IDs display on your screen. Since BC 235XLT will appear as numbers. However, if you notice a mix of odd and even user IDs, for example 6477, 2560, 6481, 6144, 1167, etc., then you are probably monitoring either a Type I or Hybrid system.
  • Page 51: Selecting A Preset Fleet Map

    If you are in Trunking Scan mode: Press to return to conventional mode if you have been monitoring a trunking bank. Press and hold until you hear two short beeps. You’ll hear two short beeps and BANK and TRUNK will begin to flash in the display.
  • Page 52: Programming A Fleet Map

    Press The scanner exits the Trunking Programming mode, acquires the data channel, and begins searching using the preset map you chose. Note: You will now begin to see Type I Fleet-Subfleet IDs. For example, 100-12, 100-9, 000-12, 400-8, etc. See User Defined Fleet Maps in the Appendix for more information about Type I IDs.
  • Page 53: Programming A Hybrid System

    Press the size code for the first block. Press The next available block displays. Repeat Steps 7 and 8 until you have selected a size code for each block. For specifics about each size code, see Fleet Map Size Codes in the Appendix.
  • Page 54: Care And Maintenance

    Care and Maintenance General Use Turn the scanner off before disconnecting the power or replacing the batteries. Always write down the programmed frequencies in the event of memory loss. If memory is lost, simply reprogram each channel. The display shows there has been a memory loss.
  • Page 55: Repairs

    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. Birdies All radios can receive “birdies” (undesired signals). If your scanner stops during Scan mode and no sound is heard, it may be receiving a birdie.

    User Defined Fleet Maps Type I Programming Information When a Type I system is designed, the address information for all the IDs 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.
  • Page 62 If you don’t already know the size codes used, you’ll have to guess at them. But since you don’t have to figure out all the blocks at once, this isn’t as hard as it seems. Select a size code for a block, and then press communications.
  • Page 63 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. S-12 can only be assigned to Blocks 0, 2, 4, or 6. S-13 can only be assigned to Blocks 0 and 4. S-14 can only be assigned to Block 0.
