[. . . ] w w 300-Channel Trunk Tracking Scanner BC 245XLT TM Operating Guide UDZZ01818ZZ Precautions Before you use this scanner, please read and observe the following: EARPHONE WARNING!Be sure to use only the recommended optional monaural earphone (EP009). Use of an incorrect earphone or stereo headset may be potentially hazardous to your hearing. The output of the phone jack is monaural, but you will hear it in both headphones of a stereo headset. [. . . ] Note: If you lockout an ID in Search mode, it is also locked out in Scan List mode. Conversely, if you lockout an ID while in Scan List mode, it is locked out in Search mode. For information about Scan Lists see page 48. Restore a Single ID To unlock a single ID, follow these steps: 1. Press . 2. 3. The ID is unlocked and the next locked ID displays. 44 Restore all IDs To unlock all locked out IDs at once, follow these steps: 1. Press to unlock all the IDs at once. 2. Note: If you unlock all the IDs, then the Scan List Memory mode displays. Press to scan the IDs stored in your Scan Lists or press to return to the Search mode. Press to return to the Search mode. Searching Tips ID Delay Mode n Use the key to select the Delay mode if it's not active. Other groups may use the system, but your scanner will only look for the ID in the display. Note: If you consistently miss responses while in ID Delay mode, you may need to change the default system type or change the fleet map you're using if you're trying to track a Motorola Type I system. For Motorola Type II or EDACS, if you're missing pieces of conversations, you've likely left out one or more of the frequencies used by the system. 45 Hold Mode n Press to hold on a particular ID in the display. You can hold a specific talk group, such as fire department on-scene operations, no matter which frequency the group uses. n Press to continue searching the entire trunked system. ID Monitor Mode n If you press and hold for 2 seconds, until you hear two short beeps, you will select the ID Monitor mode. SEARCH begins flashing in the display, and all active talk group IDs begin to display in succession. You won't hear conversations in this mode, but this is an excellent way to determine which talk groups are the most active. Note: Locked out IDs display during ID Monitor mode with the L/0 icon turned on. n Press to continue searching the entire trunked system. Channel Activity Indicators The BC 245XLT has 20 Channel Activity Indicators to visually display a trunked system's activity when you select delay, hold, scan etc. You'll always know which frequencies are in use and how much communication traffic is occurring. 46 Each frequency you program in a trunking bank corresponds to an activity indicator at the top of your scanner's display. The way in which the Activity Indicators display provide you with information about the system you're tracking. n 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. The Scanner does not show activity bars for private or phone interconnect calls for EDACS® systems. The indicator which flashes when an ID displays represents the frequency being used by the talk group. If you're holding on an ID which isn't active, the activity indicators will turn on and off as other groups use the system. n Note: n n Note: If more than 20 channels are stored in a bank, then the indicators represent multiple channels. For example, if 28 channels are programmed, the first 8 activity indicators each represent two channels. n The display may change from showing channel activity indicators to Scan List memory positions. 47 Scan Lists Each bank of your BC 245XLT can be a trunk tracking bank or it can be a conventional scanning bank. When you designate a bank as a trunking bank, your scanner sets up 10 Scan Lists, which are simply lists used to store your favorite IDs. [. . . ] The FLEETS and SUBFLEETS cannot be shown at this scale because there are 2048 possibilities. Sizes vary but most large cities and other agencies have blocks of 128 channels. Your scanner shows EDACS talk groups in AFS (Agency-Fleet-Subfleet) format. And with the XPAND feature (see page 50) you can easily include nearby, related channels in the same Fleet or Agency. Assuming that you have the system frequencies programmed, and your scanner is locked to the control channel, you can select a desired city by simply searching on the AGENCY part of the AFS talk group number.
