Terminology
What is Scanning?
Unlike standard AM or FM radio stations, most two-way
communications do not transmit continuously. The BC250D
scans the channels you program 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 BC250D can search each of its 17 bands to find active
frequencies. This is different from scanning because you are
searching for frequencies that have not been programmed
into your scanner. The scanner automatically chooses
between two speeds while searching.
Turbo Search, can search the VHF FM bands at up to 300
steps 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.
In a trunked radio system, which contains up to 28 different
frequencies, radio users are divided into groups, often called
talkgroups, and these talkgroups are assigned specific IDs.
When someone in a talkgroup uses their radio, a brief burst
of data is broadcasted before each transmission. The trunking
system computer uses this data to temporarily assign each
radio in a talkgroup to an available frequency. If the group
using a frequency stops broadcasting or pauses between
BC250D 9/20/2 2:51 PM Page 7
![](/img.php?id=280065&img=bgb.png)
replies for a few seconds, they are removed from the
frequency so another talkgroup 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. Following a conversation on a trunked system
using a scanner is difficult, if not impossible. Because when
there's a short break during the conversation you're
monitoring, it’s possible that the talkgroup will be assigned
to a completely different frequency in the trunked system. This
type of scanning is difficult and frustrating.
TrunkTrack changes this! Not only does your new BC250D
scan channels like a conventional scanner, it actually follows
the users of a trunked radio system. Once you know
a talkgroups 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. A glossary of other commonly used
terms is provided in the back. (Refer to the "Glossary of
Terms" section.) But if you're already an experienced scanner
operator, you may want to skip to Trunked System on page
50.
What is APCO Project 25 Digital
Communications?
APCO Project 25 is a modulation process where Voice
communications are converted into digital communications.
This conversion is similar to the technology used with digital
mobile phones. There are several types of project 25 systems
available!
- Conventional – One frequency with digital voice.
- Trunked with analog control channel and digital voice –
many frequencies shared by many departments and the
control channel is analog with digital voice. Control channel
operates at 3600 Band.

Feature Highlights
•Trunk Tracking – Follow UHF High Band UHF
800/900MHz trunked public safety and public service
systems just as if conventional two-way communications
were used.
•Digital Capable – With the APCO 25 Digital card (BCi25D)
installed, you can monitor project 25 systems.
•Multi-Track – Track more than one trunking system at a
time. Scan conventional and trunked systems at the same
time.
•1000 Channels – Program one frequency into each
channel. You must have at least one channel programmed
to use the Scan mode.
•17 Bands, 10 Banks – Includes 17 bands, with Aircraft and
800 MHz.10 banks with 100 channels each are useful for
storing similar frequencies to maintain faster scanning
cycles or for storing all the frequencies of a trunked system.
•25 MHz-1300 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, 512-806MHz.
•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. You can also assign trunking priority
talkgroups.
•Priority Plus Scan – You can keep only priority channels
you assigned in the selected bank.
•Preprogrammed Service (SVC) Search – Allows you to
toggle through preprogrammed public safety, news media,
TV broadcast audio, Ham, CB, FRS, special low power,

Listening Safely
To protect your hearing, follow these guidelines when you use
an earphone or headphones.
•Do not use the earphone to listen to the WX alert siren
test. The volume is not adjustable and damage to your
hearing could occur.
•Do not listen at extremely high volume levels. Extended
high volume listening can lead to permanent hearing loss.
•Set the VOLUME to the lowest setting before you begin lis-
tening. After you begin listening, adjust the VOLUME to a
comfortable level.
•Once you set the VOLUME, do not increase it. Over time,
your ears adapt to the volume level, so a volume level that
does not cause discomfort might still damage your hearing.
Connecting the REMOTE Cable
You can transfer the programmed data to and from another
BC250D or BC785D scanner using an remote cable. See
"Clone Mode" on page 79. You can also upload or download
the programmed data to or from a PC using third party
software. See "PC control MODE" on page 78.

Basic Operation
Note: See the Controls and Indicators on page 2 while
reading this guide.
Turn the Scanner On
Turn the VOLUME inside control clockwise out of the detent
position. The scanner automatically starts scanning. Since
there are no frequencies programmed in your scanner initially,
you may not receive any signals. Once you set the squelch
and program some frequencies, you will be hearing
conversations regularly.
Setting the Squelch
To set the squelch, you must be in the hold mode, and you
should not be receiving a signal on your scanner.
1. Press HOLD/MAN until you do not hear a signal.
2. Make sure that the VOLUME is set to a comfortable
listening level.
3. Think of the Squelch
Control as a gate.
Turn SQUELCH
outside control fully
counter-clockwise. This
raises the "Squelch
Gate" so high that only
very strong signals can
get through.
4. Turn SQUELCH fully

Next you must program some frequencies (Page 26). It is
recommended that you read the next part "Understanding the
Menu System" because it will assist you in accessing and
understanding many of the features. Later in a section called
"Additional Features", you will find explanations on how to
disable the keypad acknowledgement tones, how to mute the
audio, how to change the appearance of the display and other
general features.
Understanding the Menu System
It is very important for you to understand the Menu screen.
To navigate through the Menu screen is really quite simple.
Many of the features of this scanner, can only be accessed by
the menu screens. There are several ways to get through the
screens. First of all, press MENU/BACK to get started.
Any time you want to exit this mode or simply quit from where
you are, repeatedly press MENU/BACK until the scanner
returns to the original state. Anytime you are in the Menu
mode, the audio will be muted.
To assist you in understanding the Menu screen, flow charts
are provided towards the back of the manual so you can
follow along. Two things to remember are rotate the through
the menu and execute the command. For simplicity, we have
chosen to rotate the VFO key up or down in order to scroll
through the menu and the Ekey for entering or executing a
command. Once you have pressed the Ekey and executed
the final choice (for instance, ON or OFF), the display backs
up to the previous level of options.
Also direct entry of the numbers in the flow chart will get you
through the screens, but the other screen options are not
visible. This method should be used only after you have gone
through the manual at least once. A tearout shortcut card (see
page 4) is provided to assist you in the direct entry method for
commonly used features.
Next page is the first level of the Menu screen. These levels
are then expanded from 100 to 102 page of the manual. You
will find a description section to explain the meanings of these
functions on the next pages. Then, you will be walked through
all the steps of programming, scanning, searching, and
trunktracking.
☞Hint: You can check the options you programmed on the
display when you press and hold MENU/BACK for
2 seconds in the following modes.
•Scan mode/Scan hold mode (as well as Trank
mode).
•Chain Search mode/Chain Search hold mode
•ID Search mode/ID Search hold mode

you want to program. You can program range 1
through 10, one at a time. For each of the ranges,
the following options can be modified.
1:CHAIN SEARCH
When you turn chain search setting to ON,
you can use chain search.
2:SEARCH RANGE
1:RANGE
Enter the upper and lower frequency
limits of the SEARCH range.
2:STEPS
You can assign a variety of step sizes
to the search range.
Note: The default step is usually
acceptable and is listed on
page 1.
3:MODE
You can change the default receive
mode with this menu item.
4:ALPHA TAG
You can enter an alpha tag for any or
all of the search ranges.
5:TRUNK
During chain search mode, when the
scanner finds any active frequency,
trunking system will be active. 4
frequency plans apply to the Control
Channel Only feature (For details on
page 73).
3:DELAY
Set the delay for the search ranges to ON or
OFF. This applies to each range for chain
search mode, and each service group for
service search mode (See SCAN OPTION-
CONVENTIONAL-DELAY for details).
4:ATTENUATOR
Set attenuation for all search ranges.
(See SCAN OPTION-CONVENTIONAL-
ATTENUATOR for details).
5:TONE DATA
The default mode is OFF. This means that
you will receive all transmissions on any
frequencies that are active within your search
range(s). By selecting CTCSS or DCS you
can set the radio to receive only a particular
subaudible tone to be received during your
18
BC250D 9/20/2 2:52 PM Page 18
![](/img.php?id=280065&img=bg16.png)
search. You can also lockout a particular
CTCSS or DCS tone.
You may wish to do this if you want to search
a range but not hear transmissions
on any frequency that has a particular
subaudible tone.
Note: Through the System Menu you can set
the radio to operate in Tone Search
mode during Search as well. In this
mode, the radio will automatically
determine the active subaudible tone
on any frequency received during the
search.
6:AUTO STORE
You can automatically store active
frequencies found during a search into the
memory.
You can select which bank you want to
program the found frequencies. Note that the
audio will be muted during Auto Store.
2:SCAN OPTION
1:CONVENTIONAL
Choose the channel number. The following options
are available for the selected channel only. Repeat
using a different channel number, if necessary.
1:FREQUENCY.
Allows you to edit or enter a frequency in
each channel you select.
Also you can set an alphanumeric text tag for
each programmed frequency.
2:DELAY
The delay for all programmed channels is
2 seconds. At the end of any transmission the
scanner will remain on the frequency for
2 seconds before resuming scanning.
This will allow you to catch most replies.
3:TONE DATA
You can set a CTCSS (analog) or DCS
(digital) sub-audible tone for a frequency.
To do so you must have the SQ Mode in the
System Menu set to Tone SQ. You can also
program a subaudible tone easily by pressing
the Ekey in scan hold mode after
programming a frequency. This will bring up
the Tone Data menu without your having to
navigate the Menu. By doing this you will
19
BC250D 9/20/2 2:52 PM Page 19
![](/img.php?id=280065&img=bg17.png)
receive all transmissions on the frequency,
regardless of the subaudible tone, except the
one which you have locked.
Any transmissions with that tone will not be
received.
4:BEEP ALERT
You can set a Beep Alert on a per-channel
basis to alert you when specific frequencies
are active. For example, you may wish to be
alerted anytime a mutual aid fire frequency
is active. With beep alert, you will hear three
beeps at the start of each transmission that
you have flagged as such. You will also
notice that as you scroll pass the flagged
channel(s), you will hear three beeps.
5:ATTENUATOR
The BC250D comes with an RF Attenuation
feature. If you are near an unusually strong
signal source, the signal may overload the
scanner. The scanner may stop repeatedly
on that signal and miss other transmissions.
The RF Attenuation feature works in all
modes and attenuates (reduces) the incoming
signal strength to prevent stronger signals
from overloading the scanner.
6:STEPS
Your BC250D is programmed with default
step sizes for each frequency range (see
page 1). Steps are important if you are
interested in using the VFO to tune off-
frequency from a frequency programmed into
memory or if you wish to program a frequency
that the default step size will not accept.
For example, in VHF Hi-band mode, the
default step size between 148 and 162 MHz
is 5 KHz. However, the FCC has recently
instituted 7.5 KHz channel intervals. If you
wish to enter 155.4075 into the scanner
without changing the default step, the scanner
will change the programmed frequency to
155.4100. Use the menu to change the
default step size to 7.5 KHz and then you will
be able to enter 155.4075.
7:MODE
Default receive modes are also programmed
into memory. AM for aircraft and CB bands,
for example. All frequencies (other than TV
broadcast audio) above 400 MHz are
20
BC250D 9/20/2 2:52 PM Page 20
![](/img.php?id=280065&img=bg18.png)
received in NFM mode which helps prevent
adjacent channel interference.
You can change the default settings on a
per-channel basis with this Menu item.
2:TRUNK
Choose the Trunk bank. The following options are
available for the selected trunk bank only. Repeat
using a different trunk bank, if necessary.
1:TRUNK TYPE
You will need to assign the correct trunking
type for the bank you are about to program.
If you want to listen to a Motorola Type I
system, you will need to use this menu option
to assign the same. If you do not know the
type of trunking system you are about to
monitor, refer to the guide included with the
scanner or check out
www.trunktracker.com.
Note: Some trunking systems require that you
know the channel order. In these cases
you will also need to start programming
the trunked system at the start of the
bank. The scanner defaults to the most
common type of trunking system,
Motorola Type II 800.
2:TRUNK CHANNEL
1:FREQUENCY
To use Trunk tracking, you need to
program a frequency for at least one
channel.
Also you can enter an alpha tag for
each channel in this menu.
2:STEPS
You can assign a variety of step sizes
to the channel.
3: MODE
You can change the receive mode in
this menu.
3:TALK GROUP SET
You can program IDs into the Scan List
memory either during Trunk Scan or Search
without going into the Menu. However, you
can also use the Menu to program IDs.
This is particularly helpful when you are not
near the trunked system you wish to later
monitor. You can set it up and have it ready
to go at some later time.
21
BC250D 9/20/2 2:52 PM Page 21
![](/img.php?id=280065&img=bg19.png)
After you have selected the Scan List location
(1-10), you can then do the following:
1. Program ID number
2. Set an alpha tag
3. Assign a Beep Alert to the ID. Whenever
that ID is active, you will hear three beeps
at the start of the transmission.
4:DELAY
You can set a Delay for a trunk system on a
bank by bank basis. The delay time is 5
seconds, and this setting can not be changed.
5:ID LIST TAG
Assign an alphanumeric tag to any or all of
the 10 Scan Lists for the system. During ID
Scan Mode, you will see the ID List Tag (on
the bottom text line) along with any alpha tag
you may have set for an ID. In Search mode,
you will see any Bank Tag you have set.
6:L/O ID REVIEW
Use this menu item to review the IDs that you
have locked out during Search and Scan.
Rotate the VFO up or down to view the IDs
that have been locked out. To leave the
lockout IDs unchanged, press MENU/BACK
to back out of the menu. To unlock an ID,
press the L/O key. To unlock all the IDs that
have been locked out, press and hold L/O
key for about 2 seconds.
7: ACTIVITY ID
Set ACTIVITY ID to ON, when your scanner
finds any other active ID during your scanner
receives any transmissions on the ID, the
active ID appears every 0.5 seconds.
8:I-CALL (MOTOROLA/EDACS)
Most communications within a trunked system
are group calls where one unit (such as a
dispatcher) communicates with all the units
within his/her group (all the patrol vehicles on
the east side of town, for example). The units
within this group comprise what is typically
known as a talkgroup. There are some
communications which are direct unit-to-unit
conversations where one individual converses
with another individual. The call is initiated by
a radio and is directed to another single radio.
Within the system, no one outside of these
two users hears the conversation.
Your BC250D defaults to I-CALL OFF mode.
22
BC250D 9/20/2 2:52 PM Page 22
![](/img.php?id=280065&img=bg1a.png)
You can hear these conversations
by using this Menu item to turn the I-CALL
function to ON. In Search mode, with
I-CALL ON, you will hear both talkgroup calls
and I-CALLs. You can also set I-CALLs to
I-CALL ONLY during which you will monitor
only I-CALLs in Search mode. You can also
program I-CALL IDs into Scan List memory.
OR
8:ID SCAN LIST (LTR)
When scanning an LTR system you can only
turn Scan Lists OFF and ON when an LTR
talk group that you have entered into memory
is active. To provide you with another method
to turn Scan Lists on and off, you can use this
Menu item which only appears when you
have selected LTR in Trunk Type.
9:EMERGENCY ALT (EDACS)
In EDACS trunked systems, you can set an
alert for an EDASC transmission received.
Set EMERGENCY ALERT to ON, and
EMERGENCY flashes on the display and you
will hear beep alerts when you receive an
EDASC emergency transmission.
9:STATUS BIT
OR
9:STATUS BIT (MOTOROLA)
On Type 2 trunking systems there is a
method by which specialized types of
communications utilize unique talkgroup
numbers. An emergency call will occur on
a unique talkgroup from its primary
assignment, for example. Because the
BC250D defaults to Status-Bit On mode, you
never need to worry about missing these
transmissions. If you've programmed
talkgroup 33264 into Scan List memory, for
example, and there is an emergency call
within the group, you will hear it on 33264.
0:EDACS ID FORM (EDACS)
You can change to display the talkgroups in
decimal mode, but this mode does not
provide you with the flexibility that you get
with AFS. The BC250D defaults to show the
talkgroup number in AFS mode (Agency-
Fleet-Subfleet). For details on AFS see pages
23
BC250D 9/20/2 2:52 PM Page 23
![](/img.php?id=280065&img=bg1b.png)
65~67. OR
0:END CODE (MOTOROLA)
When this function is disabled, the radio looks
for squelch before returning to the control
channel instead of waiting for the disconnect
tone. Only in rare instances
will you need to adjust the default settings.
The condition to return to control channels
depends on whether signal is present
or not.
:CNTRL CH ONLY
(TYPE 1/TYPE 2 800, 900)
With this mode you will be able to track
Motorola Type I and II 800 and 900 MHz
trunked systems by simply entering the
control channel which manages the trunked
system. You will not have to program the
voice channels. There are 4 channel plans
which you can select from.
3:SYSTEM OPTION
1:DIMMER
Allows you to change the brightness of the display.
Also you can change the lighting length of time.
2:SCREEN MASK
Screen Mask allows you to limit what appears on the
display to the alpha tags that you have set for a
channel along with a few function icons. Screen Mask
removes the frequency, receiving mode tone data
and signal strength bars. This mode is particularly
useful in public safety vehicles where "information
overload" is already a problem. Screen Mask does
not work in Search mode.
3:KEY BEEP
Use this function to turn OFF the keypad
acknowledgement beep. The default setting is ON.
4:ENTER LOCK
Use Enter Lock to prevent accidental re-programming
of channels, tone (CTCSS/DCS) and talkgroups
entered into memory. The default setting is OFF.
5:PC CONTROL
Use this function to set the transfer speed (baud rate)
at which your personal computer (PC) communicates
with the scanner when downloading information into
your scanner using the Uniden national database or
third party software. See page 78 for details.

25
6:CLONE
You can clone all the programming, including
frequencies, talkgroups and alpha tags as well as
bank settings and other parameters from one
BC250D to another.
7:DATA SKIP
A scanner will normally stop on any transmission it
receives. This means the BC250D will occasionally
stop on data signals and unmodulated transmissions.
You can automatically skip many of these types of
transmissions during search.
8:SQ MODE
The SQ Mode allows you to set at your option,
whether the scanner will stop on all active
transmissions on a particular frequency or it will only
respond to transmissions with a pre-set subaudible
tone. This applies to both conventional search and
scan modes. The options are as follows:
1. CSQ - The default setting is CSQ (carrier
squelch). In this mode the scanner will stop on
any transmission on a programmed frequency
(Squelch mode does not apply to trunking).
2. TONE SQ - In Tone Squelch mode, if you have
set a subaudible tone (CTCSS or DCS) for a
frequency, the scanner will only stop on that
frequency if the transmission includes the
prescribed tone.
3. TONE SEARCH - In this mode, as soon as the
scanner stops on any (non-trunked) channel, the
scanner will begin to search for any subaudible
tone that is being used on a transmitted
frequency. The scanner will check each CTCSS
tone sequentially and it will find DCS tones
instantly.
9:BANK TAG
Allows you to set an alphanumeric text tag for
individual banks in the scanner (1-10).(The "0" key
represents Bank number 10.) For example, you may
wish to set the Bank one text tag as Law
Enforcement, the second bank as Fire, etc.
10:BATTERY SAVE
When you set BATTERY SAVE to on in this menu,
BATTERY SAVE is active in Scan hold mode(except
priority scan mode).
:APCO Card
When you set optional card (Bci25D) and
select ENABLE in this mode, you can
activate Digital Communications. See page
76 for details.

Programming Tips
•Do not program a weather frequency into one of the
channels, since weather channels transmit continuously.
Use the Weather Search feature to select the weather
information band.
•Group similar services into a bank. For example, program
police frequencies in channels 1 through 10 and
fire/emergency into channels 51 through 60, 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, rotate the VFO
up to go to the next higher channel.
•Write down your programmed channels and frequencies
BC250D 9/20/2 2:52 PM Page 29
![](/img.php?id=280065&img=bg21.png)
and put them in a convenient place in case of accidental
reprogramming.
•Frequencies are rounded off according to the step of each
channel.
•When you are overwriting a tagged channel with a new
frequency, the previous alpha tag will be deleted. You must
re-enter the alpha tag.
•When programming frequencies, a 2 second delay is set
automatically and can not be changed.
Deleting a Stored Frequency

You can deselect banks from active scanning by pressing
their number on your keypad. The indicator for each
deselected bank turns off, and the bank’s channels are not
scanned.
Note: One bank must always be active. You cannot
deactivate all ten banks at the same time. If you try to
turn off all the banks, the first bank is automatically
selected.
To restore a bank to active scanning, press the banks
number on your keypad.
The banks indicator will display again.
3. During normal scanning the
scanner skips
unprogrammed or locked

Digital and Trunked
Systems
Your BC250D is designed to digital communication system
(using optional BCi25D) and track three major types of
trunked radio systems. These systems are described here.
❖APCO Project 25 Systems - Digital systems which support
the APCO Project 25 protocol developed by the
Telecommunications Industry Association (TIA) and
Electronic Industries Alliance (EIA). Systems can
operate in conventional, trunked and mixed-modes
(analog and digital) in any frequency band including
UHF, VHF and 800 MHz.
❖MOTOROLA - Including Type I, Type II, Hybrid,
SMARTNET, and Privacy Plus.
Motorola systems are widely used by public safety and
business users. Most are on the 800 MHz band, and
recent systems are appearing on other bands. (See

"Narrowband" 4800 baud systems.
"Wideband" systems are mostly on the 800 MHz band,
and are used by public safety, utilities, and business
users. Some systems are used on the VHF and UHF
bands.
"Narrowband" systems are used in the 935-940 MHz
band, many by utilities.
(See page 64)
❖EDACS SCAT - These systems are mainly used in the
Midwestern United States and are one-channel
trunking sites using the EDACS format.
❖LTR - These systems are mostly for business users, and
found on the UHF, 800 and 900 MHz bands. (See
page 68)
For details on the operation and programming for all of these
systems, see pages 48-77.
When tracking these types of systems, remember these
important points:
•Your scanner defaults to monitor Motorola Type II systems;
however, you can change this if the system in your area is
different. (The types of systems are discussed below.)
•The frequencies for many of the trunked public safety
systems are listed in the TrunkTracker National Public

Digital and Trunked
Systems
Selecting or Changing Trunking System Type
Before using the Trunk Tracking system, you must select the
trunk type.
1. Press MENU/BACK.
2. Select SCAN OPTION-TRUNK by
rotating the VFO and pressing E.
3. Select the bank number using the

Programming Trunking Frequencies
After you finish to selecting a trunked type you want to track,
store the frequencies in one of the 10 available banks in your
scanner. Remember that you can only store one trunking
system in each bank.
Important: If you are programming an EDACS or LTR
trunked system, you must enter the frequencies
in a specific order. Check the frequency guide
included with the scanner for the frequencies in
your area. For additional frequencies, check the

Setting the Squelch
For 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 it is set too high (CCW) in some cases it
could prevent your scanner from locking to the Control
Channel reliably. If it is set too low (CW) it will slightly delay
finding the Control Channel. The best setting is the same as
for conventional reception, and is not critical.

different ways. You will find that Search, Hold, Lockout and
Scan, Delay are all similar to conventional scanning.
❖TRUNKED SEARCH lets you hear all system talkgroup
activity (unit-to-unit I-Calls may be received as well).
This is the best way to get started.
❖ID SEARCH HOLD works with Search mode to let you
quickly freeze reception on an interesting transmission.
Or you can manually specify a talkgroup with DIRECT
ENTRY in ID HOLD.
❖ID LOCKOUT works with Search and Scan to exclude
talkgroups that you don't want to hear.
❖ID SCAN lets you receive those talkgroups that you
store in Scan Lists.
❖ID SCAN HOLD lets you selectively listen to a
talkgroup in your Scan Lists.
❖ID DELAY works with each talkgroup to be delayed for
5 seconds when the communication ends.
When receiving EDACS systems, remember that Uniden's
AFS talkgroups give you powerful flexibility. In a few key
presses, you can specify a single talkgroup, a fleet, or an
entire agency in all the above modes. Read the section
"EDACS Reception" to understand how this works.
Note: To switch ID SCAN or ID SEARCH, press and hold
TRUNK in the trunked system.
Trunked Search
Once you have programmed all the frequencies for a trunked
system, SEARCH will let you immediately start hearing
transmissions. It is suggested you try SEARCH mode first.
1. Press SCAN, and select the bank(s) you wish to receive,
just as you select banks in conventional scanning.
2. Press TRUNK to enable trunked reception. The radio will
seek and acquire the trunked system control channel. The
scanner will now be in MONITOR mode. You will hear the
control channel and see active talkgroups on the display.
You will not hear the voice transmissions in MONITOR
mode.
☞Hint: MONITOR mode is an excellent way to observe
system activity and determine which talkgroups are
most active. Locked out IDs display during MONITOR
mode.
3. Press SEARCH to begin searching and receiving. You will
hear talkgroups and see them on the display.
52
BC250D 9/20/2 2:52 PM Page 52
![](/img.php?id=280065&img=bg38.png)
Talkgroups display differently in Motorola, EDACS and LTR
systems. You should read the appropriate parts of this guide
to understand the formats.
The display indicates the bank and the type of trunked system
you are monitoring. You can change this to display a bank tag
by using the System Option menu.
Regardless of the system, you won't know exactly who you
are receiving until you listen for a while, or refer to frequency
guides or internet sites such as www.bearcat1.com.
Of course, figuring out who each ID represents is half the fun
of TrunkTracking.
Later, when you learn more about a system, you will want to
store lists of talkgroups. Then you can scan specific agencies
and users, and use the many other features your radio
provides.
ID Search Hold and Direct Entry ID Hold Mode
Just like in Conventional Search, HOLD lets you pause ID
Search on an interesting transmission without storing the
talkgroup into memory.
If you hear an interesting ID during SEARCH mode, and want
to continue listening to it --
•Press HOLD/MAN to stop the search.
If you want to listen to a specific ID, while in HOLD --
•Use the keypad to enter the ID you want and press
SCAN, RSM or SEARCH (SEARCH key can not be
used for EDACS).
If you want to resume searching --
•Press RSM to return to Search
mode.
Note: ID Hold feature is also applied to
ID Scan mode.
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
encumber their communications, and you may want to lock
out these unintelligible broadcasts.
To Lockout an ID, press L/O when the ID you want to
lockout displays.

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 55.
EDACS BLOCKOUT is a powerful form of ID LOCKOUT
that can be used only with AFS and
EDACS systems. This feature lets you
lockout entire Agencies or Fleets, not just
individual talkgroups. Using ID
BLOCKOUT you can, for example,
prevent Search from stopping on any of hundreds of
talkgroups in the Utilities agency. You can do this with just a
few key presses. To use ID BLOCKOUT just enter the
Agency- part, or the Agency-Fleet part, of the talkgroup code
and press L/O. For example, to Blockout Agency 4 in Trunk
Search, press HOLD/MAN, 0, 4, (decimal key), and then
L/O. For other ways to use partial AFS entry, be sure to read
the section "EDACS Reception".
Review ID Lockout
You can check all IDs already locked out.
1. Press MENU/BACK.

Scan Lists
Each bank of your BC250D can be a trunk tracking bank and
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.
Each list can contain up to 10 IDs, so you can store a total of
100 IDs for each trunk tracking bank. (1000 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 and you can lockout any one
(and up to 9) of the 10 scan lists by pressing the
corresponding numeric key. When an ID is active, the scan list
number icon into which it is programmed will appear on the
display. You can program your scan lists either manually or
during trunking search mode.
REVERSE Key
Use the REVERSE key while trunking to toggle between
viewing the active banks and the active Scan Lists. To see
which is currently active, check the display for either Bank or
List.
Check the web site www.bearcat1.com/free.htm for a
complete list of talkgroups for your area that you can program
into your Scan Lists.

It’s very similar to conventional priority although there is no
"interrupt" during the transmissions. Priorities are checked in
between transmissions.
With Priority On, you can hold on an ID in your Scan List,
such as Scan List 6, memory position 7, and the scanner will
check all the priorities in all the active Scan Lists in between
any transmissions on the ID on which you’re holding. The
lowest numbered priority will be checked first. For example,
the priority ID in List 1 will be checked before the priority in
List 2, etc.
Note: This function does not work in LTR tracking.

0, HOLD/MAN
Set ACTIVITY ID to ON, when your scanner finds any other
active ID during a transmission is received, the active ID
appears every 0.5 seconds.
I-Call (Motorola/EDACS)
I-Calls are direct unit-to-unit transmissions that are not heard
by other system users. Your BC250D can receive these
transmissions. How you receive I-Calls depends on whether
you are in Search or Scan mode.

BC250D 9/20/2 2:52 PM Page 59

During I-Call reception the display will show the Unit ID
number of either the transmitting or receiving mobile unit, not
a talkgroup. Unit IDs will display differently according to the
type of trunked system, and will replace the n's shown here.
EDACS and MOTOROLA TYPE 1 innnnn
MOTOROLA TYPE 2 7nnnnn
Hint -- There are thousands of Unit IDs in typical systems,
but relatively few I-Calls at a given moment, so it is
normally best to let the scanner receive any I-Calls
without trying to specify particular units.
I-CALLS IN SEARCH MODE
In SEARCH mode, the scanner default is that I-Call reception
is OFF. This means that I-Calls will not be received until you
program them to be ON. You have three choices for
controlling I-Call reception. Through the Menu system, go to
SCAN OPTION - TRUNK - select bank number - I-
CALL, and make your selection. The menu choices are:
You can HOLD any I-Call IDs. Because you can only hold on
one ID, and there are two IDs involved in any I-Call
communication (the transmitting and the receiving units), you
might not hear the full conversation, but you probably will.
☞In SEARCH mode, when you hear an interesting I-Call,
you can enter the instant shortcut (decimal key)
then RSM to enter I-Call ONLY mode. This blocks all
talkgroup traffic and lets you hear just the I-Call.
To return to normal reception, you must use the Menu
system to select the ON or OFF option.
Note: When storing I-Call IDs, remember that the ID will be
for only one of the units – either the transmitting or
receiving unit. Unless you specifically want to receive a
certain ID, it might be better to use the special code in
the HINT below.
I-CALLS IN SCAN AND HOLD MODE
You can store I-Call IDs in Scan Lists, just like talkgroup IDs,
for use by ID Scan and Manual modes. To program a specific
I-Call Unit ID into a Scan Lists:

or 700000 in a Motorola Scan Lists or Digital.
Then, whenever you SCAN this entry, or select it in
HOLD mode, the scanner will receive any active I-
Calls, regardless of the Unit IDs.
Note: Motorola I-CALL tracking performance may vary
between systems.
Multi-Track
The BC250D allows you to track more than one system at a
time. Here are some highlights of this feature:
❖You can actually track up to 10 trunking systems at
one time.
❖You can trunk, scan, or search and scan conventional
frequencies at the same time.
❖You can program conventional frequencies in the same
bank as trunking systems.
After the scanner finishes checking a trunked system
for activity, it will conventionally scan the other
frequencies in the bank (remember, only trunking
frequencies are programmed in TRUNK mode).
To scan a mix of trunking and conventional banks, select the
banks you wish to be active with trunking Off, then press
TRUNK. The scanner will instantly begin scanning. If you
have not programmed a trunking bank with talkgroup ID’s, you
will receive NO ID (----) message for that bank.
You can switch to SEARCH mode and the scanner will search
for any active ID’s on the system.
Multi-Track Operational Details
When more than one trunk system is active (for example two
or more trunked systems or a trunked system and one or
more conventional frequencies), the radio jumps between
systems/frequencies as follows:
TRUNK SCAN: The scanner moves to a trunked system
and looks for IDs in your Scan List(s) for up to 1 second. If
it finds no activity on your programmed talkgroups, it
.
.
BC250D 9/20/2 2:52 PM Page 61
![](/img.php?id=280065&img=bg41.png)
moves on to conventional channels in the same bank or to
the next active bank.
If the scanner finds that a talkgroup in one of your active
Scan Lists is on the air, you will begin to hear that
communication and the scanner will of course display the
proper talkgroup number and any alpha tag. When the
communication ends, the scanner will wait for 5 seconds
for any further replies and, if none, the scanner will move
to the conventional channels in the same bank or to the
next bank.
The scanner will not look for any other IDs within the same
trunked system (as this would slow the scan process).
Note that if you press RSM while you are listening to one
ID, the scanner will check to see if another ID in your Scan
List is active. It will disregard the ID to which you were just
monitoring.
TRUNK SEARCH: This mode works similarly to TRUNK
SCAN. If the scanner finds any (non-locked-out) ID when
it checks the control channel, you will hear it. You will then
hear any replies that follow within 5 seconds. After that the
scanner will move on and not continuously search the
system for additional IDs (on busy systems you would never
leave the system if this were the case). Note that if you
press the RSM key while monitoring one ID, the radio will
check if any other IDs are active (it will disregard the ID you
just left), and if none are active, it will move on.
SCAN & SEARCH Icons
For the first time on a Uniden scanner, you will see both the
SCAN and the SEARCH icons active at the same time.
This indicates that the radio is scanning conventional banks
and Trunk searching trunking banks. When the radio is
trunking, only the SEARCH icon will be illuminated. Note
that to start a conventional search, you must place the radio
in conventional hold mode and then press the SEARCH
key.

EDACS®Reception
EDACS®Tracking
TrunkTracker III now allows tracking of EDACS®trunked
systems. Until now these widely used systems have been
almost impossible to monitor with a conventional scanner.
With your TrunkTracker III listening to EDACS(s) is
remarkably easy, and perhaps even easier than conventional
scanning.
EDACS systems use 'Transmission Trunking', which means
that each transmission is assigned a new frequency. As the
conversation moves through the system's frequencies, your
TrunkTracker III automatically follows it.
This chart shows a 30 second sample of EDACS
transmissions. Eight different talkgroups are using the system
as their transmissions switch between the thirteen system
frequencies.
Notice how the dotted line shows talkgroup 02-023 moving
from channel to channel. Your BC250D can clearly and
automatically follow this talkgroup, or any other, as you select.
EDACS systems are organized in a logical way that keeps
related talkgroups together. Your scanner is designed to take
maximum advantage of this organization to make your
scanning easy. It lets you zero in on just the part of the
system you want to hear, whether it is an individual channel
or an entire department or city.
Programming EDACS System Frequencies
When you program EDACS frequencies, it is critical that you
store each one in the CORRECT LOCATION. By the nature
of EDACS systems this is necessary for tracking. This often is

An EDACS®Trunked system
This chart shows how talkgroups are
organized within an EDACS system
at the AGENCY level. The individual
talkgroups cannot be shown at this
scale because there are over 2000.
However the chart can show the 16
Agencies in this example. The system is
logical and easy to understand. EDACS
systems are typically arranged in an
outline structure.
The system users are given blocks of
talkgroups. 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 talkgroups
in AFS (Agency-Fleet-Subfleet) format.
This helps you see, at a glance, who
you are monitoring. And with the partial-
entry feature you can easily include
nearby, related channels in the same
Fleet or Agency. You can just as easily
exclude entire unwanted Fleets and
Agencies.
When in Search mode, with the system frequencies
programmed, and your scanner locked to the control channel,
you can select a desired city by keying in the AGENCY part of
the AFS talkgroup. For example, you can select the entire city
of Sullivan with 4 key presses 0, 3, (decimal key),
SEARCH.
When you hear an interesting talkgroup, capture it to your
scan list by pressing Eduring the transmission.
Or HOLD on it by pressing the HOLD/MAN key.
If you want to monitor the Sullivan Police Dispatch channel
(which is talk group 03-062), press 0, 3, (decimal key),
0, 6, 2, RSM.
Your scanner can also work in DECIMAL format.
This talkgroup 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
decimal is useful if you need to work from decimal talkgroup
lists.
Special EDACS®Features
AFS Partial Entry Feature
AFS is Uniden's method of encoding EDACS talkgroups.
AFS stands for 'Agency-Fleet-Subfleet'.
AFS talkgroups are used in all EDACS reception -- in ID
SEARCH, ID LOCKOUT and ID SCAN Scan Lists. The powerful
AFS Partial Entry feature designed into the BC250D lets you
use either a complete talkgroup code, or just the most
significant part.
This feature lets you expand or
narrow searching and
scanning to one of 4 levels.
By entering only the desired part
of an AFS talkgroup,
you can select 2048 talkgroups,
128 talkgroups, 8 talkgroups, or a single talkgroup.
For example, you could program every talkgroup in a police
department with just 4 key presses. You can use the AFS
Partial Entry feature anywhere that you need to specify
EDACS talkgroup.
Your BC250D can also enter or display EDACS talkgroups in
decimal format (0-2047).
Select SCAN OPTION - TRUNK - select bank Number -
EDACS ID FORM by rotating the VFO and pressing E.
And change it to DECIMAL and press E. You can use this
feature to translate decimal talkgroups lists to the much more
powerful AFS format.
Examples of how you might use AFS are shown above in the
description of an EDACS trunked system, and elsewhere in
this manual. It is very easy to use. Be sure to become familiar
with AFS Partial Entry, and your scanning will become far
more flexible and efficient.
Emergency Call Alert
Your BC250D alerts you when an EDACS Emergency
transmission occurs.
EDACS systems often provide users with an 'Emergency'
mode on their radios. Users in trouble can alert the dispatcher
and other units and get priority access to the radio system.
When a user activates Emergency mode, EMERGENCY will
flash the display during the entire transmission. At the
BC250D 9/20/2 2:52 PM Page 65
![](/img.php?id=280065&img=bg45.png)
66
beginning of each transmission it will sound a distinctive
emergency alert tone three times.
Patch Tracking
The BC250D can follow EDACS patched talkgroups.
EDACS systems sometimes bring several talkgroups together
in a 'Patch'. A patch might be used by a police agency at night
to provide a single channel with a single dispatcher for a wide
area. A patch is created when a single, temporary talkgroup
substitutes for the original talkgroups. While the patch is
running, which may be for hours or days, the original
talkgroups cease to be used. If you were monitoring one of
these talkgroups, you might think there was no traffic, but in
fact the talkgroup was operating at the different temporary
number.
If a talkgroup in your Scan List is patched, your scanner will
continue to receive it under its new identity until the patch has
ended. When a patch is being received, the radio will display
PATCH ID, and will show the temporary common talkgroup
plus all the included talkgroups in a cycling display.
The BC250D is limited to following one patch.
The temporary talkgroups used for patches are usually found
in AFS code 15-xxx, and sometimes 00-xxx.

LTR®Reception
LTR®Tracking
LTR®(Logic Trunked Radio) systems are trunking systems
used primarily by business or private communications service
providers, such as taxicabs, delivery trucks, and repair
services. These systems encode all trunking information as
digital subaudible data that accompanies each transmission.
Users on an LTR system are assigned to specific talkgroups,
which are identified by the radio as six digit numbers.
These numbers are in the form AHHUUU, where:
A= Area code (0 or 1)
H= Home repeater (01 through 20)
U= User ID (000 through 254)
When the scanner receives a transmission on a channel set
to the LTR mode, it first decodes the LTR data included with
the transmission. In the ID Search mode, the scanner stops
on the transmission and displays the talkgroup ID on the
display. In the ID Scan mode, the scanner only stops on the
transmission if the LTR data matches a talkgroup ID that you
have stored in the bank’s talkgroup ID list and have not
locked out.
LTR systems are frequently programmed so that each radio
has a unique ID code.

Motorola Reception
Motorola Tracking
There are really two types of Motorola trunking systems.
These are usually referred to as Type I and Type II systems.
Type I only occurs on some 800 MHz systems. All VHF, UHF
and 900 MHz trunking systems use Type II.
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 talkgroups,
and these talkgroups are also assigned unique IDs. Some
radios have access to only one talkgroup, while others have
access to many talkgroups. The talkgroup(s) each radio can
access is called the radio’s affiliation(s).
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 needs to 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, its 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, which is discussed further in this
manual.
The disadvantage of a Type I system is that when PTT is
pressed, the brief burst 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
68
BC250D 9/20/2 2:52 PM Page 68
![](/img.php?id=280065&img=bg48.png)
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 its possible to select a
Preprogrammed Fleet Map or create a Custom Fleet Map for
your area.
For VHF and UHF Type II trunking systems, you will need to
know the base, spacing frequencies and offset channels.
See page 72 for details.
Fleet Map Programming
If you have programmed a trunk tracking bank for Motorola
type and press TRUNK to start Multi-Track, you will see user
IDs display on the display. Since the BC250D 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 systems.
You may also notice that you are missing responses when
you hold on an active ID. Unlike Type II, Type I/Hybrid
systems require a Fleet Map that sets specific Fleet-Subfleet
parameters. It is easy to select a Fleet Map for your scanner;
what is not 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/Hybrid 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 Preset Fleet Map
1. Select TYPE 1 for the Trunk Type.
(Refer to "Selecting or Changing
Trunking System Type" on page 50.)
2. Select the map you want to
program by rotating the VFO and
pressing E.
The scanner returns to the other programming items.
Note: You will now begin to see Type I Fleet-Subfleet IDs.

See "User Defined Fleet Maps in the Appendix" for
more information about Type I IDs.
How do you know if the preset map is correct? You will have
to listen to see if you're following complete conversations.
If not, you should try another preset map.
Programming a Fleet Map
You may want to read "User Defined Fleet Maps" in the
Appendix before programming a Fleet Map. It contains a
detailed explanation of Scanner Fleet Map Programming, as
well as a table listing the Fleet Map Size Codes.
1. Select TYPE 1 for the Trunk Type.
(Refer to "Selecting or Changing
Trunking System Type" on page 50.)
2. Select USER CUSTOM by rotating
the VFO and pressing E.
3. Select the size code for the first block
by rotating the VFO.
4. Press E.
The next available block displays.
5. Repeat step 3 and 4 until you have
selected a size code for each block.
For details about each size code,
see "Fleet Map Size Codes"
in the Appendix.
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.

Setting the Base, Spacing Frequencies and
Offset Channel for Motorola
VHF/UHF Trunked Systems
To properly track Motorola VHF and UHF trunked systems
you must enter what is known as the base, the spacing
frequencies and offset channels for each system.
To find these out, check the www.trunktracker.com or
www.bearcat1.com/free.htm and other web sites and
frequency resources.
To enter the Base, Spacing Frequencies and Offset Channel:
(You can set up to three sets of these, but almost all systems
only use one set)
1. Press MENU/BACK.
2. Select SCAN OPTION-TRUNK by rotating the VFO and
pressing E.
3. Select the bank number by rotating the VFO and pressing
E.
4. Select TRUNK TYPE-TYPE 2 UHF or TYPE 2
VHF by rotating the VFO and pressing E.
5. Select BASE CONFIG from 1 - 3 by
rotating the VFO and pressing E.
6. Enter a new Base Frequency with the
keypad.
7. Press E.
The display changes for entering the
Spacing Frequency.
8. Enter a new Spacing Frequency with
the keypad.
Note: You can only enter within a range of 5-100 kHz, and
5 or 7.5 or 12.5 kHz multiples.
9. Press E.
The display changes for entering the Offset Channel.
10. Enter a new Offset Channel with the
keypad.
Note: You can only input within a range
of 380-759.
11. Press E.
The display changes for entering the next Base
Frequency.
12. To exit from this mode, press MENU/BACK repeatedly.

Note: •If the system is not tracking properly, you may need
to try a new Base Frequency or Offset Channel or
you may be missing frequencies from the system.
•You can set up to three Base, Spacing and Offsets
for Motorola VHF/UHF trunked systems.
13. The Offset Channel for the first set should be CH380 (just
press MENU/BACK to confirm this as the default).
14. After you have pressed MENU/BACK to confirm CH380,
the display will change to allow you to set the second (of a
maximum of three) Base/Space/Offset combinations.
Since almost all systems only use one set, press
MENU/BACK to exit the programming mode and return to
scanning.
Toggling the Status Bit
On Type II trunking systems there is a method by which
specialized types of communications utilize unique talkgroup
numbers. An emergency call will occur on a unique talkgroup
from its primary assignment, for example. Because the
BC250D defaults to Status-Bit On mode, you never need to
worry about missing these transmissions. If you have
programmed talkgroup 33264 into Scan List memory, for
example, and there is an emergency call within the group, you
will hear it on 33264.
The only time you may wish to turn Status Bits Off is if you're
trying to figure out the proper Fleet Map of a Type I trunking
system. To turn Status Bits Off, enter into the Menu mode and
select SCAN OPTION - TRUNK - select bank number -
STATUS BIT. (This feature does not apply to EDACS and
LTR operation within the scanner.) Then rotate the VFO to
change the setting (ON to OFF) and press Eto program your
change.
Control Channel Only Mode
When this function is activated, trunking is performed using
Control Channel data only. Voice channel (also known as
"DATA channel") frequencies do not have to be programmed
into memory. When using this feature, the scanner will display
CC and channel activity indicator bars will not operate.
This feature only applies to Motorola 800 MHz and 900 MHz
systems.
To turn this function on, choose Motorola TYPE 2
800 MHz or 900 MHz or TYPE 1 in the Menu mode.
Then set to the desired control plan by selecting SCAN
OPTION - TRUNK - select bank number - CNTRL CH
72
BC250D 9/20/2 2:52 PM Page 72
![](/img.php?id=280065&img=bg4c.png)
73
ONLY.
You must choose one of 4 frequency plans before you begin
to Control Channel Trunk. Note that the default, Plan 1, is the
most common. Read the description of the Plans below for
details on which may apply for you.
PLAN 1: Use Plan 1 if the last three digits of ALL the
frequencies in use end in one of the following three digits:
125, 375, 625, or 875 (example: 856.1125, 860.7375,
859.6625, 855.8875).
PLAN 2: If the last three digits of frequencies are less than
869.0000 and end in one of the following three digits (125,
375, 625, or 875) AND if ANY other frequencies end in
(000, 250, 500, or 750) use Plan 2.
PLAN 3: If the last three digits of ALL the frequencies in
use end in one of the following three digits (000, 250, 500,
or 750) use Plan 3.
PLAN 4: If the last three digits of frequencies are less than
866.0000 and end in one of the following three digits (000,
250, 500, or 750) AND if ANY other frequencies end in
(125, 375, 625, or 875) use Plan 4.
Of course you will know the Control Channel frequency itself
so that will help you determine the proper plan. If you try one
plan and you receive errors (such as the scanner jumping to
channels that are obviously not part of the system), you
should try an alternate Plan.
Note: In chain search mode, Control Channel Trunk is
activated in the menu mode (See page 18).
Note: You can assign a Fleet Map to TYPE 1 or Hybrid
systems scanned in Control Channel Only mode by
going into the Menu. You can also program IDs, set a
delay, alpha tags and all the other parameters for
systems scanned in this mode. You can then either
search the system to find new IDs or you can
program IDs into memory and then scan them.
Note: The Control Channel Only feature is an extremely
powerful tool. You can use it to determine if systems
you are familiar with may have added new
frequencies or you can use it to discover new
systems by simply finding active control channels
(using Search) and then programming them for
Control Channel operation only.
Remember that this feature only applies to Motorola
800 and 900 MHz systems, that you do have to set
the Menu for the proper system type (800 MHz of
Type 1 or Type 2 or 900 MHz) and you do have to
BC250D 9/20/2 2:52 PM Page 73
![](/img.php?id=280065&img=bg4d.png)
program the Control Channel frequency into Memory
and press and hold the TRUNK key to identify the
frequency as trunked.
Disconnect Tone Detect Option (End Code)
When this function is disabled, the radio looks for squelch
before returning to the Control Channel instead of waiting for
the Disconnect Tone. Only in rare instances will you need to
adjust the default settings.
The condition to return to Control Channels depends on
whether the signal is present or not.
To set this function to on/off, select SCAN OPTION -
TRUNK - select bank number - END CODE
(MOTOROLA).
Select DETECT or IGNOR you want to set.
EDACS SCAT
With the EDACS SCAT feature turned “ON”, the data stream
transmissions will be eliminated allowing you to clearly
monitor the voice communications on EDACS SCAT systems.
To monitor EDACS SCAT systems you only need to turn this
feature EDCS SCT. “ON” with designated frequency. You
do not need to enter group ID’s.
Note: As EDACS SCAT is different from the other tracking
feature, and it is not a feature which the scanner
tracks any ID, you do not need to program TALK
GROUP ID in the menu mode.

Channel Step Selection
You can set channel steps, 5 kHz - 100 kHz or Auto, in
Conventional mode or Chain search mode. The default
receive mode should be the proper mode setting in almost
all cases. You may wish to set some VHF channels for NFM
mode, depending on any adjacent channel interference
problems. Note that WFM is typically only used for broadcast
frequencies, such as TV audio or FM radio.
See STEPS in "Menu Description" for details.
Mute On/Off
To manually turn On the Mute function, press and hold MUTE
for more than 1 second until MUTE ON is displayed.
You will not hear any audio. This feature does not function in
the WX alert mode, because the audio is already muted. To
turn it Off, press MUTE again.

You can also set the receiving mode, AM or FM etc., in
Conventional mode or Chain Search mode.
See MODE in "Menu Description" for details.
Frequency and Channel Tuning with the VFO
Control
The VFO knob can be used for changing frequencies or
changing memory channels (for Conventional channels or
talkgroup ID Scan Lists).
1. In Conventional mode, when the setting for VFO is
channel, rotate the VFO to move up (to step up through
channels) or down (to step down through channels). If you
are in Trunk Manual mode, you will step through Scan List
memory locations (whether the CHAN or the FREQ icon
is active).
2. In Chain Search mode, when the setting for VFO is
frequency, rotate the VFO to move up to step up through
frequencies sequentially or to down to step down through
frequencies. To change the step, you will need to go into the
Chain Search menu and adjust the step for the desired
memory location.

Care and Maintenance
General Use
•Turn the scanner Off before disconnecting the power.
•Always write down the programmed frequencies in the
event of memory loss.
•If memory is lost, simply reprogram each channel.
The display shows 000.0000 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, unless you have turned OFF the
KEY BEEP in the menu system.
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 sol-
vents. Be careful not to rub the LCD window.
•Do not use excessive amounts of water.
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 L/O to lockout the channel, and then press RSM
to resume scanning.

Glossary of Terms
Alpha tag - This term refers to an alphanumeric text tag that
you can enter to describe the individual frequencies that
you have programmed. Rather than having to associate a
specific frequency to the individuals that are using it, you
can enter the actual name of the group. This will eliminate
the need for memorizing the group’s frequency.
Attenuator - This scanner comes with a feature to attenuate
or reduce the signal strength. The built-in attenuator can be
turned on specific frequencies to prevent strong signals
from overloading the scanner input, possibly damaging the
scanner or missing other transmissions due to the repeated
stopping on the stronger signal.
Clone - This term identifies the ability to set up a duplicate
scanner. This function allows you to clone all the
programming information, including frequencies, talkgroups
and alpha tags as well as bank settings and other
parameters from one BC250D to another or BC785D.
Control Channel - This is the frequency within a trunking
system that runs the system. On Control Channels (some-
times called Data Channels) you will hear a buzz saw
sound. For the most part, it is the sound of the system’s
central computer directing talkgroups to particular voice
(working) frequencies within the system.
CTCSS - (Continuous Tone Controlled Squelch System)
refers to a system where the radio receivers are equipped
with tone responsive devices which allow audio signals to
appear at the audio output, select voice processing such as
scrambling or control repeater functions only when a carrier
modulated with a specific tone is received. This method
may be used to restrict access to the repeater or receiver,
or reduce interference where several stations with output
frequencies in close proximity of each other make it difficult
to hear the conversation you are interested in. With CTCSS
squelching, you can eliminate the possibility of hearing
unwanted conversations by selecting one of the 38 standard
subaudible tones. You will only hear those transmissions
that have been programmed on specific frequencies with
the specific subaudible tone that you have selected.
DCS - (Digital Controlled Squelch) refers to a system where
the radio receivers are equipped with data burst responsive
devices which allow audio signals to appear at the audio
output, select voice processing such as scrambling or
control repeater functions only when a carrier modulated
89
BC250D 9/20/2 2:52 PM Page 89

with specific data burst is received. This method may be
used to restrict access to the repeater or receiver, or reduce
interference where several stations with output frequencies
in close proximity of each other make it difficult to hear the
conversation you are interested in. With DCS squelching,
you can eliminate the possibility of hearing unwanted
conversations by selecting one of the 104 standard data
burst subaudible tones. You will only hear those
transmissions that have been programmed on specific
frequencies with the specific subaudible tone that you have
selected.
Enter Lock - This is the term used for locking the keypad.
This prevents accidental re-programming of channels and
talkgroups entered into memory. The default setting is OFF.
When ENTER LOCK is enabled, the following functions will
be disabled:
• Enter or modify the Memory Channel frequency
• Enter or modify the Tone information
• Enter or modify the Trunking ID. ( this can be modified
through the menu screen.)
FIPS codes - For the purpose of broadcasting weather
information, the NWS (National Weather Service) has
divided the United States into regions by state and county
(or parish, where applicable) then assigned a 6 digit FIPS
code to identify each county or parish. The first digit
represents the county subdivision, the next two represents
the state, and the last three digits represent the county or
parish. Your scanner can receive all SAME alert signals
broadcasted within about a 50-mile radius of where you
install it. So if you only want to hear the counties that are
nearest to your area, you can choose specifically the FIPS
code of areas that you want. This lets you avoid hearing
warnings that apply to an area within a 50-mile radius but
not necessarily in your county or parish.
I-Call - Most communications within a trunked system are
group calls where one unit (such as a dispatcher)
communicates with all the units within her group (all the
patrol vehicles on the east side of town, for example). The
units within this group comprise what is typically known as a
talkgroup. There are some communications which are direct
unit-to-unit conversations where one individual converses
with another individual. The call is initiated by a radio and is
directed to another single radio. Within the system, no one
outside of these two users hears the conversation. This call
is referred to as I-Call.
BC250D 9/20/2 2:52 PM Page 90
![](/img.php?id=280065&img=bg5e.png)
Key Beep - This is another term for the tone you hear as a
keypad acknowledgement beep. The default setting is on.
If you have turned the Key Beep off, you now have a silent
keypad. You will not hear a tone each time you press a key.
NWR S.A.M.E. Weather Alert - In 1994, the National
Oceanic and Atmospheric Administration (NOAA) began
broadcasting coded signals called FIPS (Federal
Information Processing System) codes along with the
standard weather broadcasts for stations in your area.
These codes identify an emergency and the specific
geographic area (such as your county) affected by the
emergency. The scanner was developed with SAME
(Specific Area Messaging Encoding) technology. This
allows you scanner to receive, interpret, and display the
information about the codes so you can determine if the
emergency might affect you area.Each FIPS code identifies
a specific geographic area (defined by the National Weather
Service) so your scanner sounds an alert only when a
weather emergency is declared in those locations. This
helps you more efficiently track the weather conditions in
and around your area.
PC Control - This term is associated with the ability to
program frequencies and other useful information via a
computer by means of the Uniden national database or third
party software. You can change the transfer speed on the
scanner needed to be compatible with your PC. (See page
XX)
Scan List - When you designate a bank to be a trunking
bank, your scanner sets up 10 Scan Lists, which are simply
list of your favorite IDs. Each list can contain up to 10 IDs,
so you can store a total of 100 IDs for each trunk bank.
These lists are designed to help you organize the trunking
system users into categories.
Screen Mask - Screen Mask reduces the amount of
information that appears on the display. Alpha tags that you
have set for a channel along with a few function icons will
appear only on the display. This mode is particularly useful
in public safety vehicles where that are already overloaded
with information. Screen Mask does not work in Search
mode.
Status Bit - This term refers to Motorola Type II systems.
There is a method by which special types of
communications utilize unique talk group numbers. For
example, if all emergency calls are set to occur on a
specific talk group number then you will not miss the
transmission even if you have not programmed all the talk
group numbers. With the Status Bit on and you have
91
BC250D 9/20/2 2:52 PM Page 91
![](/img.php?id=280065&img=bg5f.png)
programmed the unique number, then you don’t have to
worry what the rest of the groups numbers are. The topic of
interest will be picked up.
Talkgroup - A group of users within a trunked system that
communicates with one another.

User Defined Fleet Maps
Type I Programming Information
When a Type I system is designed, the address information
for all the IDs are divided into 8 equal sized blocks. 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 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 "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 depends on the block
number and the blocks size code. When a Type I ID displays,
the left most digit represents the block which contains the ID.
The next two or three 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 systems 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 SCAN. 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. SIZE CODE 3 and SIZE
CODE 4 are probably the most common, followed by SIZE
CODE 10, SIZE CODE 11, and SIZE CODE 12.
Fleet Map Size Codes
Size Code Restrictions
If you select SIZE CODE 12, 13, or 14, there are some
restrictions as to which blocks can be used for these codes.
•SIZE CODE 12 can only be assigned to Blocks 0, 2, 4,
or 6.
•SIZE CODE 13 can only be assigned to Blocks 0 and 4.
•SIZE CODE 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 SIZE
CODE 12, you will be prompted for Block 2, the next block
available, instead of Block 1. And if you assign Block 0 as
SIZE CODE 14, you would not see another prompt because
all available blocks have been used.
