Uniden Receiver BC245XLT Operating Instructions

							If you experience difficulty while inTrunkTracker™mode,
try the following steps.
Problem Suggestion
Scanner won’t track the trunked
system.1. May not be a system which can be tracked by
your scanner.
2. Missing the data frequency.
3. Change to a Type 1 Scanner setup.
Review Fleet Map Programming on page 56.
Scanner won’t stop during Scan
List mode.1. No IDs have been programmed.
2. The IDs you have stored are not active.
Scanner will not acquire data
channel.1. Adjust the squelch for trunking mode.
See page 39.
2. Missing the frequency used for the data
channel. Check your frequency list.
Missing replies to conversations. 1. Change to a Type 1 Scanner setup.
Review Fleet Map Programming on page 56.
2. Try another Preset Fleet Map or Program
your own Fleet Map.
3. Check to see that all of the systems
frequencies have been entered.
Channel Activity Indicators are
flashing but no sound is heard.1. May be a private or telephone
interconnect call, which are intentionally
blocked by your scanner.
2. The ID in your display is not active.
Scanner not tracking an EDACS
system properly.1. Logical channel numbers ( frequencies)
for the system are not programmed in the correct
order. Check frequency resources and reprogram.
2. Not all frequencies for the system are
programmed. Check frequency resources.
If you still cannot get satisfactory results while using your
scanner or if you want additional information, please call or
write the Uniden Parts and Service Division. The address
and phone number are listed in the Warranty at the end of

							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. When you have assigned a size code to all
8 blocks, you’ll have defined the Fleet Map for the system
you’re tracking. Each size code determines the number of
Fleets, Subfleets, and IDs each block will have. For
example, a size code of S-4 has one Fleet, which is divided
into 16 separate Subfleets, and it has a total of 512
individual IDs.
When a block is assigned a size code, the Fleet or Fleets
created within the block are assigned a Type I ID. The way
these IDs display on your scanner depend on the block
number and the block’s size code. When a Type I ID
displays, the leftmost digit represents the block which
contains the ID. The next two digits identify which Fleet is
active, and the last digit(s) identifies the Subfleet.
The details concerning how the size codes are selected by
a Type I System designer are highly dependent on the
specific needs of the system’s users. Some organizations
may want many subfleets with only a few radios each,
while another organization may want only a few subfleets
with many radios each. Your task is to program your fleet
map with the same size code assignments as the trunked
system. If you do this accurately, you’ll track all the
Fleet-Subfleet combinations used by the system. In other
words, you’ll hear complete communications while
monitoring a trunked system.

							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 . Now listen to the
communications. If you decide you are receiving most of
the replies to the conversations with IDs assigned to the
block you just programmed, then you’ve probably selected
the right size code and can work on the next block of the
map.
Finally, for most public safety systems there are some size
codes which are more common. S-3 and S-4 are probably
the most common, followed by S-10, S-11, and S-12.

							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.
nS-12 can only be assigned to Blocks 0, 2, 4, or 6.
nS-13 can only be assigned to Blocks 0 and 4.
nS-14 can only be assigned to Block 0.
Since these size codes require multiple blocks, you will be
prompted for the next available block when programming a
Fleet Map. For example, if you assign Block 0 as an S-12,
you will be prompted for b2, the next block available, instead
of b1. And if you assign Block 0 as an S-14, you would not
see another prompt because it uses all available blocks.

							An EDACS Trunked System
84
This chart shows how talk groups may
organized within an EDACS system at the
AGENCY level. The FLEETS and
SUBFLEETS cannot be shown at this scale
because there are 2048 possibilities.
The system is logical and easy
to understand.
System users are given blocks of talk
groups. Sizes vary but most large cities and
other agencies have blocks of 128
channels. Smaller cities have only 64
or 32 channels.
In this example, the County Sheriff is
Agency 01. The city of Sullivan is Agency
03. Adams Hill and Matthew Junction share
Agency 08.
Your scanner shows EDACS talk groups in
AFS (Agency-Fleet-Subfleet) format. This
helps you see, at a glance, who you are
monitoring. 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. For example, you can select the
entire city of Sullivan with 4 key presses -
zero, three, dot, SRCH.
If you hear an interesting talk group, capture
it to your scan list by pressing E during
the transmission.
If you want to monitor the Sullivan Police
Dispatch channel (which is talk group
03-062), you key in zero, three, dot, zero, six,
two, SRCH.
Your scanner can switch between AFS and
DECIMAL display. This channel, in decimal
format, is 434. But decimal format does not
give you any information about the system
hierarchy. For example Sullivan, in decimal,
uses channels from 384 to 511. This is not
as easy to remember as Agency 03. But it
will help you if you need to use decimal
talk group lists.
