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.
The FCC Wants You To Know
BC72 Paper OM.fm Page 7 Monday, October 25, 2004 3:11 PM

The FCC Wants You To Know
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.

Understanding Scanning
Understanding Scanning
This section provides you with background 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
BC72XLT.
What is Scanning?
Unlike standard AM or FM radio stations, most two-
way communications do not transmit continuously.
Your BC72XLT 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 BC72XLT can search for 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.
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
Understanding Scanning
BC72 Paper OM.fm Page 14 Monday, October 25, 2004 3:11 PM
15
Understanding Scanning
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.
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
BC72 Paper OM.fm Page 15 Monday, October 25, 2004 3:11 PM
16
Understanding Scanning
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.
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 included
conventional frequency guide 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:

Setting Up 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 mono earphone or mono
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.
Using Internal Batteries
You can power your scanner using two alkaline or
rechargeable AA batteries (not supplied).
Using Non-Rechargeable Batteries
1. Make sure the power is turned off.
2. Slide the battery compartment cover.
3. Before you install alkaline or any other non-
rechargeable batteries, use a pointed object
such as a ballpoint pen to set REG. ALK. BATT./
NI-MH BATT. inside the compartment to REG.
ALK. BATT..

Cautions:
• Use only fresh batteries of the required size and
recommended type.
• Always remove old or weak batteries. Batteries
can leak chemicals that destroy electronic
circuits.
• Do not mix old and new batteries, different types
of batteries (standard, alkaline, or rechargeable),
or rechargeable batteries of different capacities.
5. Replace the cover.
6. When flashes and the scanner beeps
every 15 seconds, replace both batteries.
Using Rechargeable Batteries
You can also use two rechargeable batteries to
power your scanner. Before you use Ni-MH or Ni-Cd
batteries, you must charge them.
The scanner has a built-in circuit that lets you
recharge Ni-MH or Ni-Cd batteries while they are in
the scanner. To charge the batteries, set
REG. ALK. BATT./NI-MH BATT. inside the battery
compartment to NI-MH BATT., install the batteries in
the scanner, and connect an external AC adapter to
the scanner's DC 6V jack (see “Using AC Power” on
Page 23).
BC72 Paper OM.fm Page 21 Monday, October 25, 2004 3:11 PM
22
Setting Up Your Scanner
WARNING!
Do not connect either adapter to the scanner if non-
rechargeable batteries (such as alkaline batteries) are
installed in the scanner and REG. ALK. BATT./NI-MH
BATT. is set to NI-MH BATT., or if you are unsure of
the switch’s position. Non-rechargeable batteries will
get hot and can even burst if you try to recharge them.
Before you use Ni-MH or Ni-Cd batteries for the first time,
charge them for 14 hours to bring them to a full charge.
Discharged batteries take about 14 hours to fully
recharge.
Notes:
• The scanner might test rechargeable batteries
when you install them. TSt CHArg and
appear. If the batteries are good, TSt
disappears and the scanner charges the
batteries. Otherwise, no bAtt appears and the
scanner does not charge the batteries.
• Ni-MH batteries last longer and deliver more
power if you occasionally let them fully
discharge. To do this, simply use the scanner
until it beeps every 15 seconds and
flashes.
• To prevent damage to Ni-MH batteries, never
charge them in an area where the temperature is
above 113°F (45°C) or below 40°F (4°C).
• If you connect an external power source to the
scanner with REG. ALK. BATT./NI-MH BATT.
set to REG. ALK. BATT., CHArg and
appear but the scanner does NOT charge the
batteries. Make sure that you use the correct
batteries and set REG. ALK. BATT./
NI-MH BATT. to the correct position when you
connect an external power source.
BC72 Paper OM.fm Page 22 Monday, October 25, 2004 3:11 PM
23
Setting Up Your Scanner
• For longer operation, you can also use high-
capacity Ni-MH batteries to power the scanner.
This type of battery takes longer to recharge.
You can get high-capacity Ni-MH batteries at
your local electronics store.
Using AC Power
You can power the scanner using the supplied 6V,
500 mA AC adapter.
To use the scanner on AC power, plug the AC adapter
into DC 6V on the side of the scanner then plug the
other end into a standard AC outlet.
If rechargeable batteries are installed and
REG. ALK. BATT./NI-MH BATT. is set to NI-MH BATT.,
the adapter powers the scanner and recharges the
installed batteries at the same time.
Connecting the Antenna
To attach the supplied flexible antenna to the
connector on the top of your scanner, align the slots
around the antenna's connector with the tabs on the
scanner's BNC connector. Then slide the antenna's
connector down over the scanner's connector and
rotate the antenna connector's outer ring clockwise
until it locks into place.
BC72 Paper OM.fm Page 23 Monday, October 25, 2004 3:11 PM

Setting Up Your Scanner
Connecting an Optional Antenna
The scanner's BNC connector makes it easy to
connect a variety of optional antennas, including an
external mobile antenna or outdoor base station
antenna.
Note: Always use 50-ohm, RG-58, or RG-8, coaxial
cable to connect an outdoor antenna. If the antenna
is over 50 feet from the scanner, use RG-8 low-loss
dielectric coaxial cable. You can get a BNC adapter
at your local electronics store.
Connecting an Earphone/Headphone
For private listening, you can plug a 1/8-inch (3.5
mm) mini-plug earphone or mono headphones (not
supplied) into the headphone jack on top of your
scanner. This automatically disconnects the internal
speaker.
Connecting an Extension Speaker
In a noisy area, an optional extension speaker,
positioned in the right place, might provide more
comfortable listening. Plug the speaker cable's 1/8-
inch (3.5-mm) mini-plug into your scanner's jack.
WARNING!
If you connect an external speaker to the scanner's
headphone jack, never connect the audio output line
to a power supply and ground. This might damage
the scanner.

About Your Scanner
About Your Scanner
We use a few simple terms in this manual to explain
the features of the scanner. Familiarize yourself with
these terms and the scanner's features, and you can
put the scanner to work for you right away. Simply
determine the type of communications you want to
receive, then set the scanner to scan those
communications.
A frequency, expressed in kHz or MHz, is the tuning
location of a station. To find active frequencies, you
use the search function or refer to a frequency
reference.
Besides searching within a selected frequency
range, you can also search your scanner's service
banks. Service banks are preset groups of
frequencies categorized by the type of services that
use those frequencies. For example, many amateur
radio frequencies are located in the HAM service
bank.
When you search and find a desired frequency, you
can store it into a programmable memory location
called a channel. Channels are grouped into
channel-storage banks. The scanner has 10
channel-storage banks and each bank has 10
channels. You can scan the channel-storage banks
to see if there is activity on the frequencies stored
there.

About Your Scanner
Understanding Banks
Service Banks
The scanner is preprogrammed with all the
frequencies allocated to the weather, ham, marine,
aircraft, police, and fire services.
Channel-Storage Banks
To make it easier to identify and select the channels
you want to listen to, the 100 channels are divided
into 10 channel-storage banks. Each bank has 10
channels. Use each channel-storage bank to group
frequencies, such as those for the police
department, fire department, ambulance services, or
aircraft.
For example, the police department might use four
frequencies in your town while the fire department
uses an additional four. You could program the four
police frequencies starting with Channel 1 (the first
channel in bank 1), and program the fire department
frequencies starting with Channel 11 (the first
channel in bank 2).

accept.
4. To program the next channel in sequence, press
E then repeat Steps 2 and 3.
Searching For and Temporarily
Storing Active Frequencies
If you do not have a reference to frequencies in your
area, use a search (except weather service search)
to find a transmission.
Note: When the scanner starts searching, it auto-
matically turns on the delay function. To turn delay
on or off, press Func + Dly.
Service Search
You can search for weather, ham, marine, aircraft,
police, or fire transmissions without knowing the
specific frequencies used in your area. The scanner
is preprogrammed with all the frequencies allocated
to these services. To use this feature, press Func
and Svc. SRCH appears and the scanner searches
starting with the weather service bank. To select a
different service bank, repeatedly press Func and
Svc. Service mode appears on the display.
When the scanner stops on a transmission, press

press Func + or Func + to step through the
frequencies.
To release the hold and continue searching, press
Hold. Or, if you did not press Hold, simply press
Func + or Func + to continue searching.
Note: Because there are many different frequencies
allocated to fire and police departments, it can take
several minutes to search all the service frequencies.
Storing Frequencies into Channels
During Service Search
You can store frequencies you found during service
search or service search hold mode into channels.
1. Press Func and Pgm during service search or
service search hold mode. The frequency and
the lowest blank channel alternately appear.
2. Press E to store the frequency into the blank
channel. If you want to select another channel,
press Func + or Func + before you press
E. You can also use the 0-9 key to select the
bank.
If you entered a frequency that has already been
entered elsewhere, the scanner sounds an error
tone and displays the channel that was duplicated.
If you entered the frequency by mistake, press
then enter the correct frequency. To enter the
frequency anyway, press E to accept.
Scanning the Stored Channels
To begin scanning channels, press Scan.
The scanner scans through all non-locked channels
in the activated banks. (See “Locking Out Channels”
on Page 48 and “Turning Channel-Storage Banks
On and Off” on Page 47). When the scanner finds a

transmission, it stops on it. When the transmission
ends, the scanner resumes scanning.
Notes:
• If you have not stored frequencies into any
channels, the scanner does not scan.
• If the scanner picks up unwanted partial, or very
weak transmissions, turn Squelch clockwise to
decrease the scanner's sensitivity to these
signals. To listen to a weak or distant station,
turn Squelch counterclockwise.
• To ensure proper scanning, adjust Squelch until
the audio mutes.
Manually Selecting a Channel
You can continuously monitor a single channel
without scanning. This is useful if you hear an
emergency broadcast on a channel and do not want
to miss any details - even though there might be
periods of silence - or if you want to monitor a
specific channel.
To manually select a channel, press Hold, enter the
channel number then press Hold again.
Or, during scanning, if the radio stops at a channel
you want to listen to, press Hold once. (Repeatedly
pressing Hold at this time causes the scanner to
step through the channels.) Press Scan to resume
automatic scanning.

Special Features
Special Features
Close CallTM RF Capture Technology
Your scanner's Close Call feature lets you set the
scanner so it detects then displays the frequency of
a nearby strong radio transmission. Close Call RF
capture works great for finding frequencies at
venues such as malls and sporting events. You can
set the scanner so Close Call detection works "in the
background" while you are scanning other
frequencies, turn off normal scanning while Close
Call 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 detects a
frequency. You can also set the frequency band
where you want the scanner to look for
transmissions.
Unlike searching, which requires the scanner to tune
to a frequency to check for a transmission, Close
Call RF capture directly detects the presence of a
strong, nearby signal and instantly tunes to the
source’s frequency.
Notes:
• Close Call RF capture 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.
However, if you are in an area with many
transmission sources (such as pager radio
transmitters, multi-use radio towers, traffic
control devices, etc.), Close Call RF capture
might not find the transmission you are
searching for, or it might find a transmission
other than the one you are searching for.
• Close Call RF capture cannot detect satellite
dishes or any transmitter with a frequency above
or below the frequency ranges listed under
“Setting the Close Call Options” on Page 38.
Special Features
BC72 Paper OM.fm Page 37 Monday, October 25, 2004 3:11 PM

Special Features
• Close Call works better with some types of
transmissions than others. It might not correctly
display frequency information for transmitters

same area, or if the transmitter is a broadcast
television station.

Care and Maintenance
Care and Maintenance
Keep the scanner dry. If it gets wet, wipe it dry
immediately. Use and store the scanner only in
normal temperature environments. Handle the
scanner carefully: do not drop it. Keep the scanner
away from dust and dirt, and wipe it with a damp
cloth occasionally to keep it looking new.
General Use
• Turn the scanner off before disconnecting the
power.
• Always write down the programmed frequencies
in the event of memory loss.
• If memory is lost, simply reprogram each
channel. The display shows 000.0000 in all
channels when there has been a memory loss.
• Always press each button firmly until you hear
the entry tone for that key entry.
Location
• Do not use the scanner in high-moisture
environments such as the kitchen or bathroom.
• Avoid placing the unit in direct sunlight or near
heating elements or vents.
• If the scanner receives strong interference or
electrical noise, move it or its antenna away from
the source of the noise. If possible, a higher
elevation might provide better reception.
• Also try changing the height or angle of the
antenna.
Cleaning
• Disconnect the power to the unit before
cleaning.
Care and Maintenance

Care and Maintenance
• Clean the outside of the scanner with a mild
detergent.
• To prevent scratches, do not use abrasive
cleaners or solvents. Be careful not to rub the
LCD window.
• Do not use excessive amounts of water.
Repairs
Do not attempt any repair. The scanner contains no
user serviceable parts. Contact the Uniden
Customer Service Center or take it to a qualified
repair technician.
Birdies
All radios can receive “birdies” (undesired signals). If
your scanner stops during Scan mode and no sound
is heard, it might be receiving a birdie. Birdies are
internally generated signals inherent in the
electronics of the receiver.
Press L/O to lock out the channel, then press Scan
to resume scanning.
If you still cannot get satisfactory results while using
your scanner or if you want additional information,
please call or write the Uniden Parts and Service
Division. The address and phone number are listed
in the Warranty at the end of this manual. If you
would like immediate assistance, please call
Customer Service at (800) 297-1023.
