The FCC Wants You to Know
This scanner has been tested and found to comply with the limits for a scanning receiver,
The FCC Wants You To Know
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
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.

About This Manual
The screen displays used in this manual are representations of what might appear when
you use your scanner. Since what you see depends on the frequencies and user ID’s for
your area and the settings you select, you might notice some differences between what is
in this manual and what appears on your scanner.
To get the most from this manual, review the contents to become familiar with the basic
functions available. If you are new to scanning or trunk tracking, be sure to read
“Understanding Scanning” on Page 7 for a quick background on the technology behind the
hobby. The first thing you’ll need to do is plug the AC adapter into the scanner. Then you
need to connect the included antenna to the scanner. See “Installing Your Scanner” on
Page 15 if you need any help doing this.
In addition to the information in this manual, the help file included with the free demo
software includes more instructions and programming planning worksheets that are very

Understanding Scanning
UThnisdseercstiotannprdoivnidgesSycouawninthinbagckground on how scanning works. You don’t really need
to know all of this to use your scanner, but some background knowledge will help you get
the most from your BC898T.
Understanding Banks and Channels
The memory in your scanner is organized into 10 banks of 50 channels each. Each bank
can contain conventional channels as well as 1 trunking system. For each trunking system,
each bank can also store 10 groups of 10 talk group ID’s (100 per bank).
What is Scanning?
Unlike standard AM or FM radio stations, most two-way communications do not transmit
continuously. Your BC898T 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 cycle resumes until the scanner
receives another transmission.
What is Searching?
The BC898T can search each of its 17 bands and up to ten 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
one of the banks. If not, you can continue to search.
What is CTCSS/DCS?
Your scanner can monitor systems using a Continuous Tone Control Squelch (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
(Motorola’s trademarked term for Private Line). CTCSS and DCS are used only for FM
signals and are usually associated with both amateur and commercial two-way repeaters.
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 at the same time. 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.
Local frequency allocation groups set cooperative standards to establish the CTCSS and
DCS tone for each transmitter (or repeater).
You can search for the following CTCSS frequencies and DCS codes.

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 1980’s this was the primary way that radio systems operated.
Even today, there are many 2-way radio users who operate using a conventional system:
8

• 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.
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 BC898T 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 trunking systems
When tracking these types of systems, you might want to remember these important points:
• Your scanner defaults to monitor Type II systems; however, you can change this if the
system in your area is different. (The types of systems are discussed below.)
• Your scanner can track more than one trunking system at a time and scan
conventional and trunked systems at the same time.
9

• The frequencies for many of the 800 MHz public safety systems are listed in the
National Public Safety Trunked System Frequency Guide included with your BC898T
scanner.
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, 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 BC898T scan channels like a conventional scanner, it actually follows
the users of a trunked radio system. Once you know a talk group’s ID, you won’t miss any
of the action.
If you 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 Trunked Systems” on Page 42 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 plus one or more voice
channels (typically 10, 20, or 30 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 maps are included at the back of this
manual. 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 BC898T 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
11

know both the frequencies used by the system and the LCN for each frequency so that you
can program the frequencies in LCN order.
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. 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 BC898T 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 BC898T
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)
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 bank’s talk group ID list and have not locked out. LTR systems are frequently
programmed so that each radio has a unique user ID. LTR systems also need to be
programmed into your scanner in channel order.
Since many LTR systems use only odd-numbered channel slots, you would program these
systems using only the corresponding odd-numbered channels in a bank (for example,

you would program a system with channels at 1, 3, 5, and 9 into Trunk 2 channels 51, 53,
55, and 59).
Where To Obtain 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 two included conventional and
trunking frequency guides will give you a good head start on the other part of what you
need to know – what frequencies have interesting content.
Information On The Internet
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 up the frequencies and systems
used by those agencies. Here are a few useful sites:

Installing Your Scanner
These guidelines will help you install and use your new scanner:
• If your scanner receives interference or electrical noise, move the scanner or its
antenna away from the source. You might also try changing the height or angle of the
telescoping antenna.
• To improve the scanner’s reception, use an optional external antenna designed for
multi-band coverage. (You can purchase this type of antenna at a local electronics
store). If the optional antenna has no cable, use 50-70 ohm coaxial cable for lead-in.
A mating plug might be necessary for the optional antennas.
• Use an optional earphone or stereo headset with proper impedance for private
listening. Read the precautions on the inside front cover of this Owners Manual.
• Do not use the scanner in high-moisture environments such as the kitchen or
bathroom.
• Avoid placing the scanner in direct sunlight or near heating elements or vents.

Adapter Safety Feature
The AC adapter included with the scanner might be equipped with a polarized line plug —
a plug with one blade wider than the other. This plug fits into a power outlet only one way.
If you are unable to insert the adapter’s plug into an AC outlet, try reversing the plug.
Using An Optional External Speaker/Earphone/Headphone
LINE Jack
External Speaker Jack
For private listening or for listening in a noisy area, you can plug a 1/8-inch (3.5mm) mini-plug
earphone’s or headphone’s or monitor speaker’s (not included) cable into the EXT SP jack
on the front of the scanner. This automatically disconnects the scanner’s internal speaker.
Listening Safely
To protect your hearing, follow these guidelines when you use an earphone or
headphones.
• Do not use an earphone to listen to the WX alert siren or when in SAME alert mode.
The alert tone’s 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 VOLUME to the lowest setting before you begin listening. After you begin listening,
adjust VOLUME to a comfortable level.
• Once you set 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.
Using An Optional Tape Recorder
You can use a standard tape recorder or a VOX (Voice Operated Control) tape recorder
with the scanner. The tape recorder you use must have a remote jack. You need a cable
with a 1/8-inch (3.5 mm) plug (not included) to connect the tape recorder to the scanner.
You can get a cable from your local electronics store.
16
Download from Www.Somanuals.com. All Manuals Search And Download.
Connect one end of the cable to the tape recorder’s remote jack, then connect the other
end of the cable to LINE on the front of the scanner.
Remember! You must program a channel for tape recording before you can record it. See
“Recording Transmissions” on Page 38 for more information.

Installing The Scanner In a Vehicle
Mounting the Scanner
1. Select a location in your vehicle to mount the scanner. Avoid a location that could inter-
fere with your driving. In a passenger car, the ideal location is underneath the dash-
board on the passenger side.
Warning: Make sure there are no obstructions such as wires or an air bag behind the
mounting location you select. Use the shortest mounting screws that will securely hold
the mounting bracket on the mounting location you select. If you are not sure if the
mounting location is safe and free of obstructions, check with your vehicle’s dealer.
2. Use an optional mounting bracket as a template for marking the location for the mount-
ing screws.
Note: If there are screws already holding the dashboard, you can use the same screw
holes to mount the bracket.
3. Drill the necessary holes and secure the mounting bracket in
place using the screws provided with the bracket.
4. Mount the scanner to the bracket only after the wiring has
been connected to the scanner’s rear panel.
Connecting the Antenna Plug
Connect an optional mobile antenna plug into the ANT connector on the back of the
scanner. (For more information on antenna installation, please refer to the instruction
guide that came with your antenna.)
Connecting the DC Power Cord
If you are not experienced in connecting accessories to your vehicle’s fuse box, please
consult your vehicle’s dealer for advice on proper installation before completing the steps
below.
Installing a Temporary Power Cord
Warning: Do not use the cigarette lighter power cord in a positive ground vehicle.
Use an optional cigarette lighter power cord for an easy, temporary installation.

Basic Operation
Basic Operation
BTuarsnicinOgpOenratthioenScanner
Turn VOLUME clockwise to turn on the scanner, or counterclockwise until it clicks to turn it
off.
Setting the Squelch
Your scanner’s squelch control acts like a gate to reduce or eliminate noise from received
signals. Turning SQUELCH clockwise raises the gate so high that only very strong signals
can get through, while turning SQUELCH counterclockwise lowers the gate so that
everything can get through — noise, weak signals, and strong signals.
To set the squelch, you must first set the scanner to its manual mode and the scanner
must not be receiving a signal.
Follow these steps to set the scanner’s squelch.
1. Adjust VOLUME to a comfortable listening level.
2. Repeatedly press MANUAL until you do not hear a signal.
3. Turn SQUELCH fully clockwise.
4. Turn SQUELCH counterclockwise until you hear a hiss.
5. Turn SQUELCH back clockwise just until the hiss stops. This sets the squelch so that
only clearer signals can get through.
You can change the squelch setting, if necessary, to provide better performance in your area.
Using the Rotary Tuner
Use the rotary tuner to:
• Rapidly and precisely select frequencies or channels in the conventional or trunking
mode.
• Select a CTCSS tone during CTCSS programming in the conventional or trunking
mode.
• Scroll through scan and lockout lists in the trunking mode.
To use the rotary tuner, press MANUAL to stop scanning if necessary. Then, if the green
LOCK LED is on, press LOCK to unlock the rotary tuner. Then turn the rotary tuner to
select frequencies, channels, or CTCSS tones, or scroll through scan and lockout lists.
To program a channel, repeatedly press FREQ/CHAN until the CHAN LED lights. Then
turn the rotary tuner to select the channel. To program a frequency, repeatedly press
FREQ/CHAN until the FREQ LED lights. Then turn the rotary tuner to select the frequency.

Note: You can also use the keypad to enter a frequency.
Press E to program the frequency into the channel you selected.
Using the Frequency/Channel Mode Selector
Repeatedly press FREQ/CHAN to switch between channel and frequency mode. When
the CHAN LED is on, you can use the rotary tuner to step rapidly through channels. When
the FREQ LED is on, you can use the rotary tuner to tune frequencies quickly and
accurately.
Using the Lock Key/LED
Press LOCK to enable or disable the rotary tuner. When the LOCK LED is on, the rotary
tuner is locked. This prevents accidentally changing the displayed channel and frequency
while monitoring a transmission.
Manually Selecting a Channel
To manually select a channel, press MANUAL, enter the channel’s number using the
keypad, then press MANUAL again. The channel’s number and any frequency stored in
the channel appears.
Scanning Programmed Channels
Before you start to scan, you must first program channels. See “Programming” on Page 35
“Programming Trunked Systems” on Page 41 (for trunking systems) for complete
instructions.
To begin scanning, simply turn on the scanner or, if the scanner is not currently scanning,
press SCAN.
The scanner checks each system you have programmed that is not locked out and stops if
there is activity. SCAN scrolls across the display, right to left.
When the scanner receives a signal on a programmed channel, it stops on that channel
and displays the channel information.
The bank indicators A – J selected for scanning appear, and the bank you are currently
monitoring flashes. You can deselect banks from active scanning by pressing that bank’s
key (A-J). The indicator for each deselected bank turns off, and the scanner does not scan
that bank’s channels.
Note: One bank must always be active. You cannot deselect all ten banks at the same
time. If you try to turn off all the banks, the scanner automatically selects the first bank.
To restore a bank to active scanning, press the bank’s letter. The bank’s indicator appears.

Press MANUAL to stop on a channel while scanning. Press SCAN to resume scanning.
Locking/Unlocking Banks
When you are scanning conventional banks, the scanner displays the digit corresponding to
all unlocked banks. To lock out a bank so that the scanner does not scan its channels, press
the letter that corresponds to the bank. The bank’s letter disappears from the display.
To unlock locked-out banks, simply press that bank’s letter again. The bank’s letter
appears on the display and the scanner includes that bank when scanning.
Note: You cannot lock out all banks. One bank must be unlocked at all times.
Locking/Unlocking Channels
To lock out a channel so that the scanner does not stop on it while scanning, press L/O
when the scanner is stopped on that channel, or manually select the channel and press L/O.
To unlock the channel, manually select it and press L/O again.
Restoring All Locked Out Channels
You can restore all locked-out channels in a bank only when the bank is selected for scan.
Follow these steps to restore all locked-out channels in a bank.
1. If you de-selected the bank, press SCAN then press the bank’s letter.
2. Press MANUAL.
3. Hold down L/O for about 2 seconds. The scanner beeps twice and unlocks all
channels.
Priority Scanning
When priority scan is turned on, the scanner checks the priority channels in the unlocked
banks every 2 seconds between transmissions. If a signal is present on a priority channel,
the scanner switches to monitor that transmission, even if it had been stopped on another
channel. One channel in each bank is designated as the priority channel.
To turn priority scan on or off, press PRI. PRIORITY appears (if priority scan is on) or
disappears (if priority scan is off).
Note: If all priority channels in unlocked banks are locked out, P CH LOC0 T appears
when you try to turn on the priority scan mode.

Changing the Priority Channel
You cannot eliminate the priority channel, but you can change it to any of the 50 available
channels in each bank. Follow these steps to change the priority channel.
1. Press MANUAL.
2. Use the keypad to enter the channel number for the new priority channel.
3. Press MANUAL.
4. Hold down PRI for about 2 seconds.
The scanner beeps twice and the priority channel changes to the one you selected.
Using the Dimmer
Hold down DIM for about two seconds to change the display’s brightness.
Trunk Scanning Options
When you are scanning a trunked system, there are several trunking-only options
available to you. This section outlines these options.
Searching for Active Talk Groups (ID Search)
If you want to hear all activity on a trunked system, use the ID search mode by pressing
SCAN then SRC. SEARCH appears and the BC898T stops on every active talk group,
regardless of whether you have programmed it into your scanner. This makes it easy to
find unknown talk groups.
Note: If you have not yet programmed any talk group ID’s into the scanner, this is the only
trunk scanning mode available.
Searching Only Stored Talk Groups (ID Scan)
To scan only those talk groups you have stored into your scanner, press SCAN. When one
of the talk groups you have stored becomes active, the scanner switches to that
transmission and displays the ID number for that talk group.
Note: You must store at least 2 talk group ID’s in the system for ID scanning to work.
Monitoring Talk Group ID’s
To see all the talk group ID’s that are active on the system, while monitoring a trunked
system press SCAN. The scanner stops trunking the system and instead holds on the
system’s control channel. You hear the control data and the scanner displays every talk
group ID as it becomes active in the system. To resume trunk tracking, press SCAN again.
23

Holding On a Single Talk Group
To hold on an active talk group when scanning or searching, press HOLD U. The BC898T
stops scanning and holds on the current trunking system. It only receives transmissions on
the talk group that was active when you pressed HOLD U.
To select a talk group to hold on when that group is not active, while ID scanning or ID
searching the system, press HOLD U. Then, either enter the ID or (if you have stored the
ID) scroll to the ID you want to hold on.
Locking Out Talk Groups
Like conventional scanning, you can lock out unwanted talk group traffic on trunking
systems. This is particularly important if you are ID searching a trunking system, as many
systems share both voice traffic (that you usually want to hear) with some data traffic from
water meter systems, door alarms, traffic signals and other data sources that you don’t
want to hear. You can lock out up to 200 talk group ID’s at the same time.
To lock out a talk group, press L/O when the scanner stops on that group. Or, if you have
stored the talk group in an ID list, select that ID and press L/O.
Reviewing Locked Out Talk Group ID’s
You can confirm which talk group ID’s are locked out in the scanner.
To review locked out talk group ID’s, hold down L/O for about 2 seconds. The locked-out
talk group ID’s appear.
Restoring All Locked Out Talk Group ID’s
To restore all locked out talk group ID’s, hold down L/O for about 2 seconds.
EDACS Blockout
This is a powerful form of lockout that is only available for EDACS systems. EDACS
Blockout lets you lock out entire agencies or fleets, not just individual talk groups.
To use blockout, while scanning an EDACS system, press HOLD U.
Setting the Attenuator
If you are near a very strong signal source, the signal can overload the scanner’s RF front
end, causing poor audio quality or missed reception. Repeatedly press ATT until ATT
appears (to turn the attenuator on) or until ATT disappears (to turn the attenuator off).
ID Lockout
Like conventional scanning, it’s possible to lock out 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 ID’s just like other users. Also some
24

departments scramble or encrypt their communications, and you might want to lock out
these unintelligible transmissions.
To lock out an ID, press L/O when the ID appears. The ID is locked out, and the next active
ID appears. You can lock out up to 200 ID’s.
Note: If you lock out an ID in search mode, it is also locked out in scan list mode.
Conversely, if you lock out an ID while in scan list mode, it is locked out in search mode.
Restoring a Single ID
Follow these steps to unlock a single ID.
1. Hold down L/O until you hear two short beeps.
2. Use either the rotary tuner or HOLD U or LIMIT V to select the ID you want to unlock.
3. Press L/O. The ID is unlocked and the next locked ID appears.
4. Press SRC to return to the search mode.
Restoring All ID’s
Follow these steps to unlock all locked out ID’s at once:
1. Hold down L/O until you hear two short beeps.
2. Hold down L/O for about 2 seconds to unlock all the ID’s at once.
Note: If you unlock all the ID’s, Non appears. Press SCAN to scan the ID’s stored in
your scan lists or press SRC to return to the search mode.
3. Press SRC to return to the search mode.
Searching Tips
ID Delay Mode
Use the DELAY key to select the delay mode if it’s not active. This mode holds an ID for 2
seconds while you wait for a reply. In a trunked system, you can set a delay for each bank.
Other groups might use the system, but your scanner will only look for the ID in the display.
Note: If you consistently miss responses while in ID delay mode, you might need to
change the default system type or change the fleet map you are using.
ID Hold Mode
Press HOLD U to hold on a particular ID in the display. This is where the trunk tracking
effect is really noticeable. You can hold a specific talk group, such as fire department on-
scene operations, no matter which frequency the group uses.
25

ID Monitor Mode
To enter manual mode for a conventional system in a bank selected for a trunked system,
press MANUAL. All active talk group ID’s appear in succession.
Note: Locked out ID’s appear during ID monitor mode.
Scan Lists
You can program conventional or trunking frequencies into any of your scanner’s banks
When you designate a bank as a trunk tracking bank, your scanner sets up 10 scan lists
(A –J), which are simply lists used to store your favorite ID’s. Each list can contain up to 10
ID’s, so you can store a total of 100 ID’s 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 A for police ID’s, List B for fire department
ID’s, List C for emergency medical service ID’s, etc. Once ID’s are stored in lists, you can
scan them like you scan conventional frequencies. You can program your scan lists either
manually or during trunking search mode.
You can use the rotary tuner to scroll through the ID’s in your scan lists.

You can save up to 10 chain search ranges in your scanner.
1. Press MANUAL to stop scanning.
2. Press SRC.
3. Press HOLD U. HOLD appears.
4. Select the memory location where you want to save a chain search range by pressing
its bank key (A-J). If there is a chain search range already stored in that memory loca-
tion, the lower and upper frequencies of that chain search range flash.
5. Use the keypad to enter the lower frequency of the chain search range, then press E
on the keypad or LIMIT V. (Press . to enter the decimal point).
6. Use the keypad to enter the upper frequency of the chain search range, then press E
on the keypad or LIMIT V. (Press . to enter the decimal point).
Selecting Chain Search Ranges
By default, your scanner only searches one chain search range at a time. However, you
can select more than one chain search range and the scanner will search each range you
select. To select chain search ranges, press the bank keys (A-J) associated with the
ranges you want to select. When you turn on chain search, each time you press a bank
button, that chain search range is turned on or off and its letter appears or disappears from
the display.
Using Chain Search

Setting Data Skip
The scanner normally stops on any frequency with activity, and remains there until either
the activity stops or you press SRC to resume scanning. However, some signals are
identifiable by the scanner as data signals, and you can set the scanner to automatically
skip these channels.
Note: Even with this option turned on, the scanner might pause for a couple of seconds on
data transmissions before resuming.
To turn on data skip, press DATA.
Skipping Frequencies
If a particular frequency continues to interrupt search scanning, you can set the scanner so
it skips the frequency. To skip over a frequency, press L/O when the scanner is stopped on
a frequency you want to skip.
Notes:
• You can program up to 100 skip frequencies. The 101st skip frequency entered causes
the first skipped frequency to unlock.
• If all frequencies in the search range are set to skip, a beep sounds and it moves to
search hold mode. To resume searching:
a. Unskip all skipped frequencies
—- OR —
b. Select a different search frequency range.
To unskip all skipped frequencies, hold down L/O for about 2 seconds in search hold
mode.
Storing Found Frequencies
If you find a frequency you want to save into a channel, follow these steps.
1. Press E or SEND when the scanner is stopped on that frequency. All the bank indica-
tors flash.
2. Select the bank where you want to send the frequency. The display alternates between
the frequency you are sending and the lowest available channel in the bank. If there is
no free channel in the bank, the scanner automatically selects the first channel in the
bank you selected.
3. Press E.
Note: If you have already stored this frequency, the scanner displays a warning and the
channel where the frequency is stored. To store the frequency anyway, press E again.

frequencies into the available channels of the bank(s) you select. For more information
Note: You must program a chain search range for auto store to work.
1. Press MANUAL to stop scanning.
2. Press AUTO. All the bank letters flash and AUTO appears.
3. Press the bank keys (A-J) where you want to store the frequencies the scanner finds.
The bank letter(s) you select stop flashing.
If the bank you selected has no empty channels, FULL appears for about 3 seconds
and the scanner sounds an error tone. You must either delete frequencies in the bank
or select another bank.
4. Press SRC to start AutoStore.
AutoStore stops automatically when all available channels in the selected bank(s)
have been programmed.
5. Press MANUAL to exit AutoStore and return to the manual mode.
Notes:
• To exit AutoStore before all the available channels in the selected bank(s) are pro-
grammed, press MANUAL twice.
• To ensure that you catch most active frequencies for the band, you should allow
AutoStore to continue through at least a few complete sweeps of the band. Depending
on the types of services, some occasionally active frequencies might not have activity
for minutes or hours at a time.
Setting Subaudible Tones for Searching
You can set the scanner to only stop on transmissions that either have no subaudible tone
or include a specified CTCSS or DCS tone during searches. This setting affects all search
ranges. For this feature to work, you need to turn on the tone mode (see “Setting the
1. Press PRI to turn off priority scan.
2. Hold down CTCSS/DCS for about 2 seconds. CTCSS and DCS blink and the scanner

Attenuating All Search Ranges
If you are near a strong RF source, you might need to attenuate the input signal in order to
search properly. Repeatedly press ATT until ATT appears (to turn on attenuation) or until
ATT disappears (to turn off attenuation).
Setting Delay For All Search Ranges
You can set the scanner to have a 2-second delay after the end of a transmission before
searching resumes. This slows searching, but helps you prevent missing replies on a
frequency. To turn on this option for all search ranges, select the channel where you want
to add a delay then press DELAY.
Searching a Trunked Bank
Before you search a trunked bank with your scanner, consider the following:
• You can only trunk track one bank at a time.
• Repeatedly press TRUNK to toggle between the conventional and the trunk tracking
modes.
• Press DATA while in the trunk tracking mode to review which bank is currently in use.

available banks and you are in conventional mode, follow these steps to begin trunk
searching.
1. Press TRUNK then press SCAN.
2. Press a bank key (A-J) to select the trunked bank you want. For example, press B.
Note: You will see the frequencies appear quickly as your scanner looks for the data
channel, which controls the system.
3. Once the data channel is acquired, the scanner starts to trunk track. Talk group ID’s,
which represent different service groups, appear.
4. Press TRUNK again to return to conventional mode.
While searching, you won’t know exactly to whom the ID’s are assigned until you listen
awhile or until ID lists are available in frequency guides or on internet sites. However, it
usually only takes a few minutes to figure out police, fire, and emergency medical
personnel. Other ID’s might take some time, but determining who each ID represents is
half the fun of trunk scanning!

Searching for CTCSS/DCS Tones
You can use the CTCSS/DCS tone search mode to determine if the frequencies in your
area are transmitted with associated tones. If the scanner finds a CTCSS or DCS tone, the
type of tone and the frequency flash on the display. Then, if you store that frequency into a
channel, the tone is also stored in the channel.
Notes:
• You can search for CTCSS/DCS tones in scan mode, manual mode, or chain search
mode. You cannot search for CTCSS/DCS tones while the scanner is scanning a
priority channel.
• You might find frequencies that do not have a tone associated with them. This might be
because CTCSS or DCS tones are not being transmitted.
1. If necessary, press PRI to turn off priority scan.
2. Hold down CTCSS/DCS until you hear two short beeps. CTCSS and DCS appear and
begin to flash. If there is a break before a tone is identified, your scanner searches
where it left off when the transmission begins again. If a CTCSS or DCS tone is found,
the type of tone (CTCSS or DCS) and the frequency flash.
To exit tone search, press CTCSS/DCS.

Using Weather Alert (SAME)
Important: Your scanner has been primarily designed to be a radio scanner. While it
Using Weather Alert (SAME)
incorporates weather alert as one feature, 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 either search for a local NOAA weather broadcast, or be set
to alert when a SAME weather alert is broadcast on a NOAA channel.
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 emits a loud siren and displays
information about the weather alert whenever your local NOAA weather station transmits a
severe weather emergency tone.
Follow these steps to turn on weather alert:
1. Press WX to find your local weather station.
2. Press HOLD U.
3. Hold down ALERT for about 2 seconds. ALERT appears.
The scanner’s volume is muted until the warning tone sounds.
Your scanner now functions as a weather alert radio, waiting to receive a severe weather
emergency tone. When your scanner receives the emergency tone and a SAME event
code from your local NOAA weather station, it responds with a loud siren at maximum
volume (regardless of the volume control setting) and displays information about the alert.
You might see any of the following information during a weather alert:
L1 – Warning
L2 – Watch
L3 – Advisory
TST – Test
The siren will continue until the emergency tone stops transmitting.
To cancel the siren, press WX. ALERT disappears.
Searching for a Weather Broadcast
You can use the BC898T to search for your local NOAA weather channel.
To search for a weather broadcast, press WX to find an active weather channel in your area.
WX appears.
32

You might receive more than one weather station in your area. When you press WX, your
scanner finds the first active transmission. If a transmission seems weak or distant, press
WX again to find a clearer station.
Notes:
• Weather scan does not resume automatically. You must press WX again to start the
weather scan again. In some parts of the country, you might not be able to monitor
weather transmissions, such as in low-lying areas. Normally a higher location will
improve the reception.
• 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.
Programming a FIPS Code
SAME (Specific Area Message Encoding) was adopted late in the last century to replace
the wide-area alerts previously used. Weather alerts today are preceded by a digital
packet that identifies not only the type of alert, but also the geographic location for the
alert. Thus, it is possible for a weather broadcast that can be received across many
counties to be targeted to a single county. To specify a county, SAME uses a standard
established by the US Census bureau, called FIPS.
The format of a FIPS code is:
DSSCCC
Where
D = area subdivision (0=entire area)
SS = State code (00=all states)
CCC = County code (000=all counties)
For example, the FIPS code for Tarrant County, Texas is: 048439
(48=Texas; 439=Tarrant County).
Some counties are further subdivided, in which cases, the first digit will be 0 for all
subdivisions in the county and each subdivision will be labeled 1-9.
To program your scanner to alert you when the weather service issues an alert, you must set
the scanner to the alert mode, and then leave the scanner monitoring the weather service.
You cannot scan and monitor for weather alerts at the same time. To limit alerts to a specific
area, you must also program in the FIPS code(s) for the area(s) you want to receive alerts for.
The scanner can be set to either alert for all areas, or only the areas you have programmed.
You can get FIPS codes for your area by calling the National Weather Service at

1. Hold down WX for about 2 seconds to turn on weather alert.
2. Hold down E for about 2 seconds.
If the scanner has not been set to alert for any FIPS code, ____ appears. If the scanner
is set to alert for all FIPS codes, ALLFIPS appears. If the scanner is set to alert only for
the area you programmed, F1 appears.
3. Turn the rotary tuner or repeatedly press HOLD U or LIMIT V to enter a FIPS code
(1 through 15). Then enter the FIPS code and press E.
To set the scanner so it sounds an alert tone when it receives any FIPS code, turn the
rotary tuner or repeatedly press HOLD U or LIMIT V to move ALLFIPS to F1. To set
the scanner so it sounds an alert tone when it receives only one of the FIPS codes you
programmed, turn the rotary tuner or repeatedly press HOLD U or LIMIT V to select
F1 to F15. Then press E.
4. When you finish entering FIPS codes, press E.

Programming
PThreogBCra8m98mT ihnags 500 memory channels, each of which can be programmed to store one
frequency. The channels are divided into ten 50-channel banks, useful for storing similar
frequencies in order to maintain faster scanning cycles.
You can use the keypad and rotary tuner to program your scanner. You can also use the
scanner’s AutoStore feature to automatically program channels, and transfer a frequency
you already programmed from another channel to a channel you select.
Notes:
• The information in this section covers basic steps for programming frequencies and
channels. For specific information about programming conventional channels, see
“Programming Conventional Channels” on Page 39. For specific information about pro-
• Before you start to program your scanner, we recommend you download the demo
software and use the worksheets in the software’s help files to help you organize the
information you want to program.

Programming Tips
• Since weather transmissions are continuous, do not program a weather frequency into
any of the scanner’s channels. To listen to a weather transmission, press WX to select
the weather information band instead.
• Group similar frequencies into adjacent channels. For example, program police fre-
quencies in channels 1 through 50 and fire/emergency into channels 51 through 100,
and so on.
• Put the frequency you listen to the most or the most important frequency into a priority
channel.
• To quickly program a series of channels, start with the lowest number channel. For
example, when you are programming five new frequencies into Channels 4 through 8,
start with Channel 4. After you finish programming a channel, press MANUAL or
HOLD U to go to the next higher channel.
• Record channels and frequencies in some convenient place in case the scanner’s
memory is lost.
Setting the Delay Mode
A delay can be set for each programmed channel so that when scan or search stops on a
channel there is a brief pause before the scanning cycle resumes. Delay must be set for
each programmed channel, and it can be set when your scanner pauses during a scan or
when manual mode is selected.
Setting Delay in Scan or Search Mode
1. Press SCAN or set a search range then press SRC.
2. When your scanner stops on a channel, press DELAY. DELAY appears. Scanning
resumes two seconds after the transmission ends.
Setting Delay in Manual Mode
1. Press MANUAL.
2. Use the keypad or rotary tuner to select a channel.
3. Press DELAY. DELAY appears. The scanner pauses on the channel when a transmis-
sion is received.

Recording Transmissions
You can set any channel for recording while scanning. Then, if your scanner stops on a
channel you have designated for recording, the connected tape recorder begins to record
the audio.
However, before you can use this feature, you must connect a tape recorder to your
scanner. For information about attaching a recorder to your scanner, see “Using An
To program a channel for tape recording:
1. Use the keypad or rotary tuner to select the channel you want to record.
2. Press LINE. LINE appears indicating that the channel will be recorded if you connected
a tape recorder to your scanner.
3. Repeat these steps to select other channels for recording.
To record a channel, press SCAN. When your scanner stops on a channel and LINE
appears, the channel is recorded.
To turn the record feature off for a channel:
1. Use the keypad or rotary tuner to select the channel you do not want to record any-
more.
2. Press LINE. LINE turns off and the channel is not recorded.
Data Skip
A scanner will normally stop on any transmission it receives. This means the BC898T will
stop on data signals and unmodulated transmissions. You can automatically skip many of
these types of transmissions during searches. Repeatedly press DATA until DATA appears
(to activate the data skip feature) or until DATA disappears (to deactivate the data skip
feature).
When data skip is active, your scanner might pause momentarily on an unwanted signal
but will resume searching in 2 or 3 seconds.
Frequency Skip
If a particular channel continues to interrupt search scanning, you can set your scanner so
it skips the frequency. To skip a frequency, press L/O.
Note: You can program up to 100 skip frequencies. If you try to program more than 100
skip frequencies, additional frequencies you program cause the first skipped frequency to
unlock.

system. This section describes how to store known frequencies into conventional
channels.
You might want to gather all information about the systems you want to monitor before you
start to program the scanner. The “Conventional Scanning Worksheet” included in the help
The first few sections are intended to be performed in the order indicated if you are
entering information the first time. If you are editing existing information, manually select
the channel then follow the steps in the appropriate section to access the information you
want to change.
Programming conventional channels is easy - just select a channel to program, enter the
frequency, then press E.
Important: Do not use this method to program trunked systems. They require additional
information.
Changing the Frequency Step
The channel frequency step option controls the frequency step size used when you manually
tune up or down from the frequency stored in the channel. Your BC898T is preprogrammed
with the most common step sizes for each band, so you seldom need to change this
setting. To change the frequency step, press MANUAL then repeatedly press STEP until
the frequency step you want flashes.
Note: If you select a 6.25 kHz step for the 150.0000 through 161.9999 MHz frequency
range, the scanner will actually use a 7.5 kHz frequency step to match the FCC band plan
for this range. However, the scanner’s display will show 6.25 kHz as the selected step.
Setting the Modulation Mode
Radio transmissions are modulated in several different ways.
The BC898T is able to demodulate the most common transmission types. Your scanner
has the most common modulation mode preset for each band, so you seldom have to
change this option. However there are occasional services that use a modulation mode
that is not standard for that band.
To change the modulation mode, press MANUAL then repeatedly press MODE until the
modulation mode you want flashes.

checks these channels every 2 seconds to see if there is activity. If there is, the scanner
immediately switches to the priority channel.
Note: The scanner does not check trunked channels, priority channels if the channel is
locked out, or in locked-out banks.
By default, the first channel of each bank is set as priority. To change the priority channel,
manually select the channel you want to set as the priority channel. Then hold down PRI
for about 2 seconds. The scanner beeps twice and the new priority assignment is made.

Programming Fleet Maps
If you programmed a trunk tracking bank and press SRC, talk group ID’s appear. Since
your scanner defaults to monitor Type II systems, most if not all ID’s appear as even
numbers. However, if you notice an even mix of odd and even talk group ID’s, for example
6477, 2560, 6481, 6144, 1167, etc., then you are probably monitoring either a Type I or
Hybrid system.
You might also notice that you are missing responses when you hold on an active ID.
Unlike Type II systems, Type I/IIi systems require a fleet map that sets specific fleet-
subfleet parameters. It’s easy to select a fleet map for your scanner; what isn’t always
easy is selecting or programming a map that matches your particular area.
There are 16 preset fleet maps listed in the appendix that you can choose, and these are
usually a good place to start when setting up a Type I/IIi trunk tracking bank. If you choose
a preset map and still have difficulty following complete conversations, then you’ll have to
program your own fleet map.

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 two digits identify which fleet is active, and the last digit(s) identifies the subfleet.
The details concerning how the size codes are selected by a Type I System designer are
highly dependent on the specific needs of the system’s users. Some organizations might
want many subfleets with only a few radios each, while another organization might 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 ID’s assigned to the block
you just programmed, then you’ve probably selected the right size code and can work on
the next block of the map.
Finally, for most public safety systems there are some size codes which are more
common. S-3 and S-4 are probably the most common, followed by S-10, S-11, and S-12.
Size Code Restrictions
If you select size code S-12, S-13, or S-14, there are some restrictions as to which blocks
can be used for these codes.
S-12 can only be assigned to Blocks 0, 2, 4, or 6.
S-13 can only be assigned to Blocks 0 and 4.
S-14 can only be assigned to Block 0.

Since these size codes require multiple blocks, you will be prompted for the next available
block when programming a fleet map. For example, if you assign Block 0 as an S-12, you
will be prompted for b2, the next block available, instead of b1. And if you assign Block 0
as an S-14, you would not see another prompt because it uses all available blocks.
