Important Notice
This scanning radio has been manufactured so
that it will not tune to the radio frequencies
assigned by the FCC for cellular telephone usage.
The Electronic Communications Privacy Act of
1986, as amended, makes it a federal crime to
intentionally intercept cellular or cordless
telephone transmissions or to market this radio
when altered to receive them.
The installation, possession, or use of this
scanning radio in a motor vehicle may be
prohibited, regulated, or require a permit in certain
states, cities, and/or local jurisdictions. Your local
law enforcement officials should be able to provide
you with information regarding the laws in your
community.
Changes or modifications to this product not
expressly approved by Uniden, or operation of this
product in any way other than as detailed by this
Operating Guide, could void your authority to
operate this product.
The screen displays used in this manual are
representations of what might appear when you
use your scanner.

Terminology
What is Scanning?
Unlike standard AM or FM radio stations, most two-way
communications do not transmit continuously. The
BC 235XLT scans programmed channels until it finds an
active frequency.
Scanning stops on an active frequency and remains on
that channel as long as the transmission continues. When
the transmission ends, the scanning cycle resumes until
another transmission is received.
What is Searching?
The BC 235XLT can search each of its 12 bands to find
active frequencies. This is different from scanning because
you are searching for frequencies that have not been
programmed into your scanner. You can choose between
two speeds while searching. Turbo Search, a new feature
for Uniden scanners, can search the VHF FM bands at up to
300 channels per second.
What is Trunk Tracking?
Conventional scanning is a simple concept. You enter a
radio frequency in your scanner’s memory which is used
by someone you want to monitor. For example, the police
in your area may broadcast on 460.500 MHz , the fire
department on 154.445 MHz, the highway department on
37.900 MHz, etc. So when your scanner stops on a
frequency, you usually know who it is, and more
importantly, you can stop on a channel and listen to an
entire conversation. This type of scanning is easy and fun.
As the demand for public communications has increased,
many public radio users don’t have enough frequencies to
meet their needs, and this has created a serious problem.
Trunking radio systems solve this problem.
5
In a trunked radio system, which contains up to 29 different
frequencies, radio users are divided into groups, often
called talk groups, and these talk groups are assigned
specific IDs. When someone in a talk group uses their
radio, a brief bust of data is broadcast before each
transmission. The trunking system computer uses this data
to temporarily assign each radio in a talk group to an
available frequency. If the group using a frequency stops
broadcasting or pauses between replies for a few seconds,
they are removed from the frequency so another talk group
can use it.
Sharing of the available public service frequencies, or
trunking, allows cities, counties, or other agencies to
accommodate hundreds of users with relatively few
frequencies. On the other hand, following a conversation
on a trunked system is difficult, if not impossible, because
when there’s a short break during the conversation you’re
monitoring, it’s possible that the talk group will be assigned
to a completely different frequency in the trunked system.
This type of scanning is difficult and frustrating.
TrunkTracker™ changes this! Not only does your new
BC 235XLT scan channels like a conventional scanner, it
actually follows the users of a trunked radio system. Once
you know a talk group’s ID, you won’t miss any of the
action.
If you’re a new scanner enthusiast, you may want to read
the first part of this manual and use your scanner in
conventional mode before you begin trunk tracking.
Understanding scanning fundamentals and its terminology
will make trunk tracking much easier. But if you’re already
a sophisticated scanner operator, you may want to go to
Trunk Tracking on page 35 now.

Feature Highlights
Trunk Tracking – Follow 800 MHz trunked public
safety and public service systems just as if
conventional two-way communications were used.
300 Channels – Program one frequency into each
channel. You must have at least one channel
programmed to use the Scan mode.
12 Bands, 10 Banks – Includes 12 bands, with
Aircraft and 800 MHz. 10 banks with 30 channels
each are useful for storing similar frequencies to
maintain faster scanning cycles or storing all the
frequencies of a trunked system.
29 MHz-956 MHz – Indicates the range of
frequencies that can be searched within the bands
of your scanner.
Note: The frequency coverage is not continuous
and excludes the cellular band.
10 Priority Channels – You can assign one
priority channel in each bank. Assigning a priority
channel allows you to keep track of activity on your
most important channel(s) while monitoring other
channels for transmissions.
Preprogrammed Service (SVC) Search – Allows
you to toggle through preprogrammed police,
fire/emergency, aircraft, marine, and weather
frequencies.
Unique Data Skip – Allows your scanner to skip
unwanted data transmissions and reduces birdies.
Memory Backup – If the battery completely
discharges or if power is disconnected, the
frequencies programmed in your scanner are
retained in memory.
Manual Channel Access – Go directly to any
channel.
LCD Back Light – An LCD light remains on for 15
seconds when K is pressed.
Battery Save – In manual mode, your scanner
automatically reduces its power requirements to
extend the battery’s charge.

Programming Tips
Do not program a weather frequency into one of
the channels, since weather channels transmit
continuously.
Use C to select the weather information band.
Group similar frequencies into adjacent channels.
For example, program police frequencies in
channels 1 through 10 and fire/emergency into
channels 11 through 20, and so on.
Put the frequency that you listen to the most or the
most important frequency into a Priority channel.
To quickly program a series of channels, start with
the lowest number channel.
For example, when you are programming five new
frequencies into Channels 4 through 8, start with
Channel 4. After you finish programming a
channel, press M or ) to go to the next higher
channel.
Record channels and frequencies in some
convenient place in case the scanner memory is
lost.

Trunk Tracking
Your BC 235XLT is 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
Guide included with your BC 235XLT scanner.
If you have internet access, you can visit
www.trunktracker.com for current news and
information about Trunk Tracking Scanning.
* Motorola,
SMARTNET, and PRIVACY PLUS are
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).
35
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 bust 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.
36
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 SQUELCH in 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 4, you
can only select channels 91-120 with the( or)
keys.
37
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, and BANK and
TRUNK will begin to
flash in the display.
2.
Choose the bank you
want to trunk track.
For example, press
2.

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.
Use T to toggle between the conventional and
the trunk tracking modes.
Press D while 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.
39
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 keypad to
select the trunked
bank you want. For
example press 2.

group ID’s, which
represent different
service groups, begin
to display.
3.
Press T again to
return to conventional
scanning mode.
While searching, you won’t know exactly who the ID’s are
assigned to until you listen awhile or until ID lists are
available in frequency guides or on internet sites. However,
it usually only takes a few minutes to figure out police, fire,
and emergency medical personnel. Other IDs may take
some time, but determining who each ID represents is half
the fun of TrunkTracker™.
40
ID Hold Mode
During Search mode, you can hold on an ID without
entering it into memory.
1.
Press H while in

41
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.
To lockout an ID,
press O when the ID
displays.
The ID is locked out,
and the next active ID
displays. You can
lockout up to 100 IDs.
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 46.
Restore a Single ID
To unlock a single ID, follow these steps:
1.
Press and hold O
until you hear two
short beeps.
2.
Use( or) to select
the ID you want to
unlock.
3.
Press O.
The ID is unlocked
and the next locked
ID displays.
4.
Press R to return to
the Search mode.
42
Restore all IDs
To unlock all locked out IDs at once, follow these steps:
1.
Press and hold O

Searching Tips
ID Delay Mode
Use the Y key to select the Delay mode if it’s not
active. This mode holds an ID for 5 seconds while
you wait for a reply. 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.
43
Hold Mode
Press H to hold on a particular ID in the display.
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 R until you hear two short
beeps, you will select the ID Monitor mode. SRCH
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.
Channel Activity Indicators
The BC 235XLT 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.
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.
44
■
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. These
calls are not
monitored by your
scanner.
■
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.
Note: If more than 20 channels are stored in a
bank, then the indicators represent multiple
channels. For example, if 29 channels are
programmed, the first 9 activity indicators each
represent two channels.

Scan Lists
Each bank of your BC 235XLT 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
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!).
Scan Lists help you organize the trunking system users
into categories. For example, you might use List 1 for
police IDs, List 2 for fire department IDs, List 3 for
emergency medical service IDs, etc. Once IDs are stored
in lists, you can scan them like you scan conventional
frequencies. You can program your scan lists either
manually or during trunking search mode.

Fleet Map Programming
If you have programmed a trunk tracking bank and select
R, you will see user IDs display on your screen. Since
the BC 235XLT defaults to Type II systems, all the IDs
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. See Types of Trunking Systems
on page 35.
You may also notice that you’re missing responses when
you hold on an active ID. Unlike Type II systems, Type I/IIi
systems require a Fleet Map that sets specific
Fleet-Subfleet parameters. It’s easy to select a Fleet Map
for your scanner; what isn’t always easy is selecting or
programming a map that matches your particular area.
There are 16 preset Fleet Maps listed in the appendix that
you can choose, and these are usually a good place to
start when setting up a Type I/IIi trunk tracking bank. If you
choose a preset map and still have difficulty following
complete conversations, then you’ll have to program your
own Fleet Map.
Selecting Trunking Programming Mode
To change the system type which your scanner monitors,
you must be in the Trunking Programming mode. To select
this mode, follow these steps:

Programming a Hybrid System
A Hybrid system is simply a Type I system with some
blocks designated as Type II blocks. To program a Hybrid
system, follow the steps listed in Programming a Fleet Map
in the previous section. However, if you want a block to be
Type II, select Size Code S-0.
When you begin searching a trunking bank with a Hybrid
Fleet Map, you will see both types of system IDs. That is,
Type II IDs usually appear as an even number without a
dash; Type I IDs appear as a three or four digit number,
followed by a hyphen, followed by a one or two digit
number. See page 61 for more information.
53
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 000.000 in all channels when
there has been a memory loss.
Always press each button firmly until you hear the
entry tone for that key entry.
Location
Do not use the scanner in high-moisture
environments such as the kitchen or bathroom.
Avoid placing the unit in direct sunlight or near
heating elements or vents.
If the scanner receives strong interference or
electrical noise, move it or its antenna away from
the source of the noise. If possible, a higher
elevation, may provide better reception. Also try
changing the height or angle of the antenna.
Cleaning
Disconnect the power to the unit before cleaning.
Clean the outside of the scanner with a mild
detergent. To prevent scratches, do not use
abrasive cleaners or solvents. Be careful not to rub
the LCD window.
Do not use excessive amounts of water.
54
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. Birdies
are internally generated signals inherent in the
electronics of the receiver.
Press O to lockout the channel, and then press
S to resume scanning.
55

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.
4 05-12
Block
(1 digit)
Subfleet
(1 or 2 digits)
Which Fleet
within the Block
(2 digits)
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.
61
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 R. 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.
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.
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.
63
Precautions
Before you use this scanner, please read and observe
the following:
EARPHONE WARNING!
