Precautions
Precautions
Before you use this scanner, please read and observe the
following.
IMPORTANT!
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.
EARPHONE WARNING!
Be sure to use only a monaural earphone with this
scanner. You can also use an optional 32 Ω stereo
headset. Use of an incorrect earphone or stereo headset
might be potentially hazardous to your hearing.
The output of the phone jack is monaural, but you will
hear it in both headphones of a stereo headset.
Set the volume to a comfortable audio level coming from
the speaker before plugging in the monaural earphone or
a stereo headset of the proper impedance (32 Ω).
Otherwise, you might experience some discomfort or
possible hearing damage if the volume suddenly
becomes too loud because of the volume control or
squelch control setting. This might be particularly true of
the type of earphone that is placed in the ear canal.

The FCC Wants You to Know
The FCC Wants You to Know
This scanner has been tested and found to comply with
the limits for a scanning receiver, pursuant to Part 15 of
the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a
residential installation. This scanner generates, uses, and
can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause
harmful interference to radio communications.
However, there is no guarantee that interference will not
occur in a particular installation. If this scanner does
cause harmful interference to radio or television
reception, which can be determined by turning the
scanner on and off, you are encouraged to try to correct
the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the scanner and the
receiver
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1) This device may not cause harmful interference, and
2) this device must accept any interference received,
including interference that may cause undesired operation.
Scanning Legally
Your scanner covers frequencies used by many different
groups, including police and fire departments, ambulance
services, government agencies, private companies,
amateur radio services, military operations, pager services,
and wireline (telephone and telegraph) service providers.
It is legal to listen to almost every transmission your scanner
can receive. However, there are some transmissions that
you should never intentionally listen to. These include:
• Telephone conversations (cellular, cordless, or other
private means of telephone signal transmission)
• Pager transmissions
• Any scrambled or encrypted transmissions
The FCC Wants You to Know

The FCC Wants You to Know
According to the Electronic Communications Privacy Act
(ECPA), you are subject to fines and possible
imprisonment for intentionally listening to, using, or
divulging the contents of such a conversation unless you
have the consent of a party to the conversation (unless
such activity is otherwise illegal). This scanner has been
designed to prevent the reception of cellular telephone
transmissions and the decoding of scrambled
transmissions. This is done to comply with the legal
requirement that scanners be manufactured so they are
not easy to modify to pick up these transmissions. Do not
open your scanner’s case to make any modifications that
could allow it to pick up transmissions that are illegal to
monitor. Modifying or tampering with your scanner’s
internal components or using it in a way other than as
described in this manual could invalidate your warranty
and void your FCC authorization to operate it.
In some areas, mobile use of this scanner is unlawful or
requires a permit. Check the laws in your area. It is also
illegal in many areas (and a bad idea everywhere) to
interfere with the duties of public safety officials by
traveling to the scene of an incident without authorization.

Your scanner’s memory is organized in an architecture
called Dynamic Allocated Channel memory. This type of
memory is organized differently and more efficiently than
the bank/channel architecture used by traditional scanners.
Dynamic Allocated design matches how radio systems
actually work much more closely, making it easier to
program and use your scanner and determine how much
memory you have used and how much you have left.
Instead of being organized into separate banks and
channels, your scanner’s memory is contained in a pool.
You simply use as much memory as you need in the pool to
store as many frequencies, talk group ID’s, and alpha
tags as you need. No memory space is wasted, and you
can tell at a glance how much memory you have used
and how much remains.
With a traditional scanner, when you program it to track a
trunked system, you must first program the frequencies.
Since you can only program one trunking system per
bank in a traditional scanner, if there were (for example)
30 frequencies, the remaining 70 or so channels in the
bank are not used and therefore wasted. Also, since
some trunked systems might have hundreds of talk
groups, you would have had to enter those types of
systems into multiple banks in order to monitor and track
all the ID’s.
What is Scanning?
Unlike standard AM or FM radio stations, most two-way
communications do not transmit continuously. Your
BC246T scans programmed channels until it finds an
active frequency, then stops on that frequency and
remains on that channel as long as the transmission
continues. When the transmission ends, the scanning

Understanding Scanning
cycle resumes until the scanner receives another
transmission.
What is Searching?
The BC246T can search each of its 21 bands and up to
10 bands together to find active frequencies. This is
different from scanning because you are searching for
frequencies that have not been programmed into the
scanner. When you select frequency bands to search, the
scanner searches for any active frequency within the
lower and upper limits you specify. When the scanner
finds an active frequency, it stops on that frequency as
long as the transmission lasts. If you think the frequency
is interesting, you can program it into the scanner’s
memory. If not, you can continue to search.
What is CTCSS/DCS?
Your scanner can monitor systems using a Continuous
Tone Coded Squelch System (CTCSS) and Digital Coded
Squelch (DCS) system, which allow squelch to open only
when the tone you have programmed with a specific
frequency is received along with a transmission.
CTCSS and DCS are subaudible tone signaling systems
sometimes referred to as PL or DPL (Motorola’s trade-
marked terms for Private Line and Digital Private Line
respectively). CTCSS and DCS are used only for FM
signals and are usually associated with both amateur and
commercial two-way frequencies. These systems make
use of a special subaudible tone that accompanies a
transmitted signal.
CTCSS and DCS are used for many purposes. In many
cases, CTCSS and DCS are used to restrict access to a
commercial repeater, so that only those units, which
transmit the correct tone along with their signal can “talk”
to the repeater.
CTCSS and DCS are also used in areas that receive
interference where there are several stations with output
frequencies close to each other. When this occurs, you
might hear multiple communications on the same
BC246T Paper OM 062405.fm Page 19 Tuesday, June 28, 2005 10:12 AM
20
Understanding Scanning
frequency. The stations might even interfere with each
other to the point where it is impossible to clearly receive
any of the stations. A scanner equipped with CTCSS and
DCS (like your scanner) can code each received
frequency with a specific CTCSS or DCS frequency.
Then, when you receive multiple signals, you only hear
the transmission with the CTCSS or DCS tone you
programmed. If you do not receive the correct tone with a
signal, the scanner’s squelch remains closed and you
hear nothing.
You can search for the following CTCSS frequencies and
DCS codes.

Understanding Scanning
Conventional Scanning
Conventional scanning is a relatively simple concept.
Each group of users in a conventional system is assigned
a single frequency (for simplex systems) or two
frequencies (for repeater systems). Any time one of them
transmits, their transmission always goes out on the
same frequency. Up until the late 1980s, this was the
primary way that radio systems operated.
Even today, there are many 2-way radio users who
operate using a conventional system:
•Aircraft
• Amateur radio
• FRS/GMRS users
• Broadcast AM/FM/TV stations
• Many business radio users
When you want to store a conventional system, all you
need to know is the frequencies they operate on.
When you are scanning a conventional system, the
scanner stops very briefly on each channel to see if there
is activity. If there isn’t, the scanner quickly moves to the
next channel. If there is, then the scanner pauses on the
transmission until it is over.
Simplex Operation
Simplex systems use a single frequency for both transmit
and receive. Most radios using this type of operation are
limited to line-of-sight operation. This type of radio is
frequently used at construction job sites, and with
inexpensive consumer radios such as GMRS/FRS radios.
The range is typically 1-8 miles, depending upon the
terrain and many other factors.

Understanding Scanning
Repeater Operation
Repeater systems use two frequencies: one transmits from
the radio to a central repeater; the other transmits from the
repeater to other radios in the system. With a repeater-
based system, the repeater is located on top of a tall
building or on a radio tower that provides great visibility to
the area of operation. When a user transmits (on an input
frequency), the signal is picked up by the repeater and
retransmitted (on an output frequency). The user’s radios
always listen for activity on the output frequency and
transmit on the input frequency. Since the repeater is
located very high, there is a very large line of sight.
Typical repeater systems provide coverage out to about a
25-mile radius from the repeater location.
What is Trunk Tracking?
Your BC246T is designed to track the following types of
trunking systems.
• Motorola Type I, Type II, Type IIi hybrid, SMARTNET,
and PRIVACYPLUS analog trunking systems, which
are extensively used in 800 MHz communication
systems.
• LTR trunking systems
• EDACS SCAT trunking systems
• EDACS trunking systems
When tracking these types of systems, you might want to
remember these important points:
• Your scanner can track more than one trunking
system at a time and scan conventional and trunked
systems at the same time.
Conventional scanning is a simple concept. You enter a
frequency used by someone you want to monitor into
your scanner’s memory. For example, the police in your
area might transmit 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,
BC246T Paper OM 062405.fm Page 22 Tuesday, June 28, 2005 10:12 AM
23
Understanding Scanning
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.
However, as the demand for public communications has
increased, many public radio users do not have enough
frequencies to meet their needs, creating a serious
problem. Trunking radio systems help solve this problem.
Trunked Scanning
While conventional scanning worked great while there
were only a few groups wanting to use the frequencies,
with the advent of smaller, lower-cost radios more and
more agencies and businesses wanted to take advantage
of the utility of 2-way radio. As a result, the bands that
were used most became full, so new users were not able
to take advantage of the technology as quickly as they
wanted.
Trunking solved this frequency shortage by allowing
multiple groups to use the same set of frequencies in a
very efficient way. While each type of trunking system
operates a little differently (see the next few sections),
they all work on the same basic premise: even in a
system with a lot of users, only a few users are ever
transmitting at any one time.
Instead of being assigned a frequency, as with
conventional systems, each group is assigned a talk
group ID. A central computer controls the frequency each
group operates on...and this frequency selection is made
each time a user transmits. So, while on a conventional
system queries, replies, and follow-ups are all on a single
frequency, they could each be on completely different
frequencies on a trunked system. This semi-random
frequency assignment made monitoring such a system
impossible prior to Uniden’s invention of the
Trunktracking scanner.
Not only does your BC246T scan channels like a
conventional scanner, it actually follows the users of a
BC246T Paper OM 062405.fm Page 23 Tuesday, June 28, 2005 10:12 AM

Understanding Scanning
trunked radio system. Once you know a talk group’s ID,
you won’t miss any of the action.
If you are a new scanner enthusiast, you might 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 terminology
will make trunk tracking much easier. If you are already
an experienced scanner operator, you might want to go to
“Programming Motorola Systems” on Page 54, “Program-
ming EDACS Systems” on Page 58, or “Programming
LTR Systems” on Page 60 now.
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. This section describes some of the
technical data behind Motorola, EDACS, and LTR trunked
radio systems.
Motorola Trunking
While there are different types of Motorola trunking
systems, they all use the same basic trunking method.
The system consists of one control channel (or as many
as 4 per system), plus one or more voice channels
(typically 10, 20, or 28 total channels). When a user
presses Push To Talk (PTT) to transmit, their radio first
sends their talk group information to the control channel.
The computer then assigns that talk group to a specific
voice channel and transmits that data over the control
channel. All radios in that talk group switch over to the
assigned voice channel and the user can begin speaking.
This all typically takes place in about a second...the
person transmitting hears a beep from their radio when
the channel is assigned and then it is OK to start talking.
The systems in use are:
Motorola Type I – the radios send the radio ID, the fleet
and subfleet talk group ID to the control channel each
time they transmit. To program a Type I system, you need
to know the system’s fleet map. The most common fleet
BC246T Paper OM 062405.fm Page 24 Tuesday, June 28, 2005 10:12 AM
25
Understanding Scanning
maps are included in “Preset Fleet Maps” on Page 105.
You can also find fleet map resources on the web.
Motorola Type II – the radios only send the radio ID and
radio channel code to the control channel. The central
computer keeps a database of radio ID’s and which talk
group is assigned to which channel code for each radio,
so with this system the user’s radio sends only about 1/3
the data as a Type I system with each transmission.
Type II systems do not use Fleet-subfleet talk groups;
instead they use a 5-digit ID for each talk group.
Type IIi Hybrid — these systems support a mix of both
Type I and Type II users. Like Type I systems, you must
know the system’s fleet map to ensure proper tracking.
EDACS Trunking
EDACS trunking works in much the same way as
Motorola trunking with a couple of major differences.
In an EDACS system, each frequency used by the
system is assigned a Logical Channel Number (LCN) so
that less data needs to be transmitted by the control
channel. Also, talk groups are assigned in an Agency-
Fleet-Subfleet (AFS) hierarchy. Also, there is one
variation of EDACS called SCAT that your BC246T can
monitor.
Logical Channel Numbers – each frequency used by the
system is assigned an LCN. This information is
programmed into each user radio. When a user presses
PTT, their radio sends their AFS information to the control
channel. The computer then assigns that talk group to a
channel and sends the LCN so that all other radios in that
talk group will switch to the correct channel. To program
an EDACS system in your scanner, you will need to know
both the frequencies used by the system and the LCN for
each frequency.
Agency-Fleet-Subfleet – talk group ID’s for EDACS
systems are assigned in a way that makes it easy to see
at a glance the affiliation of the user. Each radio is
assigned a 2-digit agency identifier from 00 – 15.
BC246T Paper OM 062405.fm Page 25 Tuesday, June 28, 2005 10:12 AM
26
Understanding Scanning
For example, 01 might be used by the police, 02 by
ambulance service, 03 by the fire department, and so on.
Each agency is then subdivided up to 16 times to provide
fleet identification, and then 8 more times to identify
subfleets.
For example, the complete AFS for the Police
Department West District’s dispatch channel might be
01-062. 01 identifies the agency as the police
department, 06 identifies the fleet as the West district,
and 2 identifies the subfleet as the dispatch channel.
While these assignments are somewhat arbitrary and
vary from system to system, there are many resources on
the web for finding the assignments for most systems.
Because of the logical hierarchy of the AFS system, your
BC246T lets you assign wildcard ID’s that let you, for
example, use only one ID memory to identify all units in
either an agency or a fleet.
EDACS SCAT – EDACS SCAT (Single Channel
Autonomous Trunking) systems operate on a single
channel and alternate control data with analog voice
traffic. While your BC246T cannot track ID’s in this
system, it can eliminate the control data so that all you
hear is the voice transmissions when you monitor this
type of system.
LTR Trunking
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 control
information as digital subaudible data that accompanies
each transmission, so there is no separate control
channel. Users on an LTR system are assigned to
specific talk groups, which are identified by the radio as
six digit numbers.
These numbers are in the form AHHUUU, where:
A = Area code (0 or 1)
BC246T Paper OM 062405.fm Page 26 Tuesday, June 28, 2005 10:12 AM
27
Understanding Scanning
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 talk group ID on
the display. In the ID scan mode, the scanner only stops
on the transmission if the LTR data matches a talk group
ID that you have stored in the talk group ID list and have
not locked out. LTR systems are frequently programmed
so that each radio has a unique user ID.
I-Call (Motorola/EDACS)
I-calls are direct unit-to-unit transmissions that are not
heard by other system users. Your BC246T can receive
I-call transmissions. See “Setting I-Call (Motorola and
EDACS Systems Only)” on Page 68 for more
information about monitoring I-call transmissions.
Where To Get More Information
By itself, this manual really only provides part of what you
need to know to have fun scanning – how to program and
use the scanner.
The Internet is a great source for current frequencies and
information about scanning. Many web sites have lists of
frequencies for your area. You can use a search engine to
find and use them.
Make a list of the agencies you want to listen to, then look

Scanning Systems
To begin scanning programmed systems, press Scan.
The BC246T scans all unlocked systems in all activated
quick-key groups.
Notes:
• If no systems are programmed, or all systems are
locked out, an error message appears. Program a
system or select a system to scan.
• When scanning multiple systems, the BC246T scans
systems according to the assigned quick key.
Systems assigned to quick key 1 are scanned first,
then 2, 3, 4, etc. Systems not assigned to a quick key
are scanned last. Within a quick key, systems are
scanned in the order they were assigned.
• Within a system, channels are scanned according to
the assigned channel group, with the same priority as
described above for systems.
• The BC246T scans a system for the duration you set
using the System Hold Time option (see “Setting the
System Hold Time” on Page 64). For trunked
systems, the scanner moves to the next system after
the hold time expires, the current transmission ends,
and the channel delay expires. Conventional systems

Preprogrammed System Tips
All systems preprogrammed into the scanner are
assigned to quick key 9. To turn the preprogrammed
systems on or off, simply press 9 while scanning.
Notes:
• The systems preprogrammed into the scanner are
located primarily in major metropolitan areas. You
might not be able to receive one or more of these
preprogrammed systems.
• You might hear transmissions on frequencies assigned
to very distant stations. This will happen if a local
system also uses the same frequency.
You can scan preprogrammed systems more efficiently
by preventing the BC246T from scanning systems that
are not in your area. There are three ways to do this:
• Lock out the faraway systems (see “Locking/Unlock-
ing Systems” on Page 43).
• Reassign your local systems to another quick key
(see “Editing the System Quick Key” on Page 63).
• Delete the faraway systems (see “Deleting Systems”
on Page 71).
Important! You cannot restore preprogrammed
systems if you delete them.
Selecting Systems to Scan
To select systems to scan, press Scan then press the
number button corresponding to the quick key assigned
to the system or systems. To stop scanning the
system(s), press the number button again.
The SYS indicators on the display show the systems that
are currently selected.
To select or lock out a system that is not assigned to a
key, press and hold while you rotate the scroll

Programming Radio Systems
Programming Radio Systems
Your BC246T comes preprogrammed with the major
analog systems used in the 25 most populous counties in
the US. However, to get the most enjoyment from your
scanner (especially if you do not live near one of these
counties), you must customize the programming for your area.
To edit an existing system, use the menu to navigate to
the system setting you want to change. This section
assumes you are programming a new system.
Programming radio systems is completed in two major
steps. Don't skip either step!
1. Plan the system.
2. Program the system into your scanner according to
the plan you prepared in Step 1.
To make planning easier, planning worksheets are
included in the back of this manual for each system type.
Copy the worksheets (or download this manual from the
Uniden America Corporation website and print extra
sheets), then use them to plan out how you will program
the scanner.
Important! Before you start programming your
scanner, make sure the batteries are fresh or fully
charged. If the scanner loses power while you
program it, its memory might be corrupted which will
require you to reinitialize it (see “Initializing the Scan-
ner’s Memory” on Page 49). All information
programmed in the scanner, including
preprogrammed systems, might be lost.
General Notes
• You can store up to 200 systems.
• Trunking systems can have up to 200 channels each.
The number of conventional system channels you
can have is limited only by the amount of scanner
memory remaining.
• You can store up to 20 channel groups per system.
• Total channels are limited to about 2500.
• Channels that have text tags use more memory than
those that do not. If you use a text tag for every
channel, total channels are reduced from 2500 (1600
is typical).

Using the Close Call Feature
Using the Close Call Feature
Your scanner's Close CallTM feature lets you set the
scanner so it detects, displays the frequency of, and lets
you hear a nearby strong radio transmission. You can set
the scanner so the Close Call feature works "in the
background" while you are scanning other frequencies,
turn off normal scanning while the Close Call feature is
working, or turn off the Close Call feature and use the
scanner normally. You can set the scanner so it alerts you
when the Close Call feature finds a frequency. You can
also set the frequency band where you want the scanner
to look for transmissions.
To turn Close Call detection on or off, press then
. When the feature is on, appears on the display
and normal operation is briefly interrupted about every 2
seconds.
Notes:
• The Close Call feature works well for locating the
source of strong local transmissions such as mobile
and handheld two-way radios in areas with no other
strong transmission sources. Several factors affect
Close Call performance, however. Performance is
increased with higher transmit power, receive
antenna tuned to the target band, and a low
background RF level. Other than the antenna, you
have no control over these factors, but they explain
why performance might vary by both location and time.
• The Close Call feature cannot detect satellite dishes
or any transmitter with a frequency above or below
the frequency ranges listed under “Setting Close Call
Options” on Page 87.
• The Close Call feature works better with some types
of transmissions than others. It might not correctly
display frequency information for transmitters using a
highly directional antenna (such as an amateur radio
beam antenna) or if there are many transmitters
operating at the same time in the same area.

Using Weather Alert (SAME)
Using Weather Alert (SAME)
Your scanner has been primarily designed to be a radio
scanner. While it incorporates weather alert as one of its
features, we strongly recommend that you not use the
scanner as your sole means for receiving emergency
alerts. Your local electronics retailer carries several
weather radios specifically designed for this function.
Your scanner allows you to search for a local NOAA
weather broadcast and set it to alert when a SAME
weather alert is broadcast on a NOAA channel. You can
also program SAME codes into the scanner and set a
weather channel as a priority channel.
In the following sections, you can also access the weather
menu from Hold mode by holding then pressing Wx.
Searching For a Weather Broadcast

Weather Scan E
The scanner starts scanning the preprogrammed weather
frequencies, and stops on the first signal. If this station is
weak, rotate the scroll control to check for other weather
broadcasts in your area.
Note: NOAA broadcasts are continuous broadcasts.
You will only lose reception if you move out of a coverage
area. If the signal is lost, the scanner resumes searching
for a weather transmission.
Turning Weather Alert On/Off
In weather alert mode, your scanner functions as a
severe weather warning radio. This is especially useful
when your area is expecting severe weather conditions
late at night. When you set the scanner to weather alert
mode, it holds on the weather channel, but does not play
the channel’s audio. If it detects a weather alert, it sounds
a tone, displays information about the weather alert, and
turns on the audio so you can hear the weather broadcast.

Programming a SAME Group
You can edit any of the 5 SAME groups in your scanner.
Each group can have up to 8 FIPS codes.
SAME (Specific Area Messaging System) is a system
developed by the National Weather Service to reduce the
number of alerts received by consumers by allowing them
to hear alerts only for the county(ies) they are interested
in. Each alert contains information about the type and
severity of the alert, as well as the specific geographic
locations affected by the alert.
The geographic locations are designated using FIPS
codes. Each county or parish in the US and its territories
are assigned a FIPS code. In addition, certain special
regions and wildcard settings can be assigned.
FIPS codes are in the format nSSCCC:
n: A special subcounty designator. For an entire county,
use 0.

User Defined Fleet Maps
Type I Programming Information
When a Type I system is designed, the address
information for all the ID’s 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 are tracking. Each size code determines
the number of fleets, subfleets, and ID’s 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 ID’s.
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 ID’s display on your scanner depend on
the block number and the block’s size code. When a Type
I ID appears, the leftmost digit represents the block which
contains the ID.
The next 2-3 digits identify which fleet is active, and the
last digit(s) identifies the subfleet.
The details concerning how the size codes are selected
by a Type I System designer are highly dependent on the
specific needs of the system’s users. Some organizations
might want many subfleets with only a few radios each,
while another organization might want only a few sub-
fleets 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 ID’s assigned to
BC246T Paper OM 062405.fm Page 107 Tuesday, June 28, 2005 10:12 AM
108
Appendix
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 program-
ming a fleet map. For example, if you assign Block 0 as
an S-12, you will be prompted for b2, the next block avail-
able, 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.

Collecting Information
Getting your scanner programmed and scanning takes a
few steps. This helps guide you through these steps that
will make it easier for you to start scanning.
1. Collect information about the system(s) you want to
monitor.
Do you want to listen to your local police and fire
departments? How about the highway patrol,
ambulance service, and aircraft? You might even
want to listen to your local utility company as they
track down a break in electrical service in your area.
Make a list of the agencies you want to listen to,
then look up the frequencies and systems used by
those agencies. The Internet is a great source for
current frequencies and information about scan-
ning. Here are a few useful sites:
•http://www.scannermaster.com/ - frequency
resources and home of Police Call.
You can also call them at 1 800 SCANNER (hours
are from 10:00 a.m. to 5:00 p.m. Eastern Time
Monday through Friday.)
•http://www.radioreference.com/ - the Internet's
premier source for user-supported radio system
information.
•http://www.bearcat1.com/ - frequency information
from National Communications.
•http://svartifoss2.fcc.gov/reports/index.cfm -
conventional frequency information on file with the US
Government
Tips:
• Scanners are designed to monitor complex radio
systems. That means that programming your scanner
might seem like a daunting task at first. Be patient if
you don't get it right the first time. You can also seek
out help locally for the systems you want to scan by
visiting the forums section of
http://www.radioreference.com/forums.
• Before you start to program your scanner, decide how
you want to organize the frequencies you want to
scan. For example, some areas are best organized by
Planning
BC246T Paper OM 062405.fm Page 109 Tuesday, June 28, 2005 10:12 AM
110
Planning
geographic location (east, north, south, west, central,
etc), while others are best organized by agency
(police, sheriff, ambulance, fire, etc.). You might even
find it easier to organize a mixture of frequencies
(north, southeast, and west for police but fire all in
one group for example).
2. Organize the system information using these system
worksheets included in this appendix.
• Use “Conventional System Worksheet” on Page 114
to organize info about conventional frequencies.
• Use “Motorola System Worksheet” on Page 115 to
organize information about Motorola frequencies.
• Use “LTR/EDACS System Worksheet” on Page 117
to organize information about LTR and EDACS
frequencies.
3. Follow the instructions in “Filling Out The Conven-
tional System Worksheet” on Page 110, “Filling Out
The Motorola Worksheet” on Page 111, and “Filling
Out the LTR and EDACS Worksheet” on Page 113 to
program your scanner.
Tips:
• Before you start, make as many copies of the
worksheets as you think you'll need. You can also go
to the download section of
http://www.uniden.com/productsupport.cfm and
download the worksheets there.
• All worksheet instructions assume that you have
completed the critical Step 1 (collecting the system
information). Don't skip this step.
• Use a pencil to fill out the worksheets. This lets you
change information if necessary.

Preprogrammed Systems
Preprogrammed Systems
Your scanner is preprogrammed with over 400 channels
covering police, fire, and ambulance operations in the 25
most populated counties in the US. The following list
details the preprogrammed information.
By default, all of the preprogrammed systems are
unlocked, and your scanner begins to scan them when
you turn it on. To speed up scanning, you can lock out
systems that are beyond your reception area (typically no
more than 25 miles using the supplied antenna).
Follow these steps to lock out systems:.
1. Press and hold .
2. While continuing to hold , rotate the scroll control
to select a system you want to lock out.
3. While continuing to hold , press L/O to lock out
the system.
4. Repeat Steps 2, 3, and 4 to lock out additional
systems.
The preprogrammed systems provide a starting point;
you will want to find out more information about your local
radio systems so you can customize the programming to
better suit your listening preferences.
Notes:
• You might hear transmissions on frequencies assigned
to very distant stations. This will happen if a local
system also uses the same frequency. Disregard the
text tag for these transmissions (e.g. if you are in
California, you aren’t really receiving Florida
transmissions even if the scanner displays
Dade County).
• To free up memory, you can delete systems that you
will not be monitoring. Refer to “Deleting Systems” on
Page 71.
• Data used for the preprogrammed information was
supplied courtesy of http://www.radioreference.com ,
the Internet’s premier scanning resource
(RadioReference is not affiliated with Uniden America
Corporation).
