1 Impor tant Notice • This scanning radio has been manuf actured so that it will not tune radio frequencies assigned by the FCC f or cellular telephone usage.
2 T erminology What is Scanning? Unlike standard AM or FM r adio stations, most two-w ay comm unications do not transmit continuously . The BC780XL T scans the channels you program until it finds an activ e frequency . Scanning stops on an active frequency and remains on that channel as long as the transmission continues .
3 T runkT rac k™ changes this! Not only does your ne w BC780XL T scan channels like a conv entional scanner , it actually follows the users of a trunk ed radio system.
4 Feature Highlights • T runk T racking – Follo ws VHF High Band, UHF , 800/900MHz tr unked pub lic safety and public service systems just as if conv entional two-wa y communications were used. • Multi-T rack – T rack more than one trunking system at a time.
5 Where to Obtain More Inf ormation Bef ore using your scanner , you must progr am frequencies into av ailable channels . The Betty Bearcat F requency Guide lists typical frequencies used around the U .S.A. and Canada that you ma y program into your ne w scanner .

36 T runked Systems Y our BC780XL T is designed to track three major types of trunked r adio systems. These systems are described here. v MO T OROLA - Including T ype I, T ype II, Hybrid, SMARTNET , and Pr ivacy Plus . Motorola systems are widely used by pub lic saf ety and business users.
37 Pr ogramming and Receiving T runked Systems Programming T runking Frequencies The first step in trac king a trunked system is storing the frequencies in one of the 10 av ailable banks in y our scanner . Remember that y ou can only store one trunking system in each bank.
38 + Important! 7. Press TRUNK f or 2 seconds. A tone sounds, and E , M , or L icon appears on the displa y according to the system selected. Note : • T o clear a mistak e while entering the frequency , press (decimal ke y) repeatedly until the displa y is cleared.
39 Setting the Squelch F or trunked reception, a good setting for the SQUELCH control is in the center of the range with the red marker pointing up . See the illustration. If set too high (CCW) in some cases it could pre vent y our scanner from locking to the control channel reliab ly .
40 T alkgroups displa y differently in Motorola, ED ACS and L TR systems. Y ou should read the appropriate par ts of this guide to understand the formats. The bottom line of the displa y indicates the Bank and the type of trunked system you are monitoring.
41 Restoring Locked-out IDs T o unlock a single ID , follo w these steps: 1. Press MENU . 2. Select TRUNK D A T A - BANK NO . - L/O ID REVIEW using s , t or VFO and pressing E , SELECT or VFO . 3. Select the locked out ID y ou want to unloc k using s or t .
42 Scan Lists Each bank of your BC780XL T can be a tr unk tracking bank and it can be a con v entional 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 y our fa v orite IDs.
T o enter an ED ACS ® ID: a. Enter ID you w ant to store. Use the f or the “dash”. b . Press E . Hint : Remember that Uniden's AFS f or mat allows y ou to enter full or par tial EDA CS IDs for powerful fle xibility in all modes. Be sure to read the section "EDA CS Reception" on page 49 to learn how this works.
ID Scan Mode 1. Press SCAN to begin scanning the lists you hav e programmed. If you ha ven't prog rammed any IDs , ERROR appears f or a fe w seconds. 2. T o remov e a Scan List from active scanning, press the number of the Scan List on y our ke ypad.
45 Setting Priority in T runking Mode Y ou can set prior ity in your trunking lists, just as y ou do in your con ventional ones . Y ou can set the prior ity by pressing and holding PRI f or 2 seconds. After you’ve set up y our Scan List, press PRI to activate it.
46 I-Call (Motorola/ED A CS) I-Calls are direct unit-to-unit transmissions that are not heard b y other system users. Y our BC780XL T can receive these tr ansmissions.
47 I-CALLS IN SCAN AND MANU AL MODE Y ou can store I-Call IDs in scanlists, just like talkg roup IDs, f or use by ID Scan and Man ual modes. T o program a specific I-Call Unit ID into a scanlist: ED A CS or Motorola T ype 1 Enter f ollowed b y the Unit ID digits, then E .
48 TR UNK SEARCH : This mode works similarly to TR UNK SCAN. If the scanner finds any (non-lock ed-out) ID when it checks the control channel, y ou will hear it. Y ou will then hear any replies that f ollow within tw o seconds (or whatev er dela y you ma y hav e set).
49 E DAC S ® Reception E DAC S ® T racking T runkT rac ker III no w allows trac king of ED ACS ® trunked systems. Until now these widely used systems hav e been almost impossible to monitor with a con v entional scanner .
50 An ED ACS ® T runked system This char t shows how talkg roups are organized within an ED A CS system at the AGENCY le vel. The individual talkgroups cannot be shown at this scale because there are ov er 2000. Howe ver the char t can show the 16 Agencies in this e xample.
51 Special ED ACS ® Features AFS P artial Entr y Feature AFS is Uniden's method of encoding ED A CS talkgroups . AFS stands for 'Agency-Fleet-Subfleet'. AFS talkgroups are used in all ED A CS reception -- in ID SEARCH, ID LOCK OUT and ID SCAN scanlists.
52 LT R ® Reception LT R ® T racking LT R ® (Logic T runked Radio) systems are trunking systems used primar ily by b usiness or private communications service providers, such as taxicabs , delivery trucks, and repair ser vices. These systems encode all trunking information as digital subaudible data that accompanies each transmission.
53 Motor ola Reception Motorola T racking There are really two types of Motorola trunking systems. These are usually referred to as T ype I and T ype II systems. T ype I only occurs on some 800 MHz systems. All VHF , UHF and 900 MHz trunking systems use T ype II.
54 Fleet Map Programming If you ha ve prog rammed a trunk tracking bank f or Motorola type and press TRUNK to star t Multi-T rac k, you will see user IDs displa y on your screen. Since the BC780XL T defaults to T ype II systems, all the IDs will appear as n umbers.
