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 wire-line  
(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.  
 
7
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.  
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.  
introduction  
Thank you for purchasing a Uniden BC125AT Handheld Scanner.  
The scanner is versatile, compact, and easy to use. In addition  
to its standard scanning features, your scanner also includes  
Close Call™ RF capture technology designed to help you detect  
and identify strong local radio signals in your area. You can  
program up to 500 frequencies into the scanner's memory either  
manually or using optional computer software. The scanner  
lets you scan transmissions and is preprogrammed with service  
banks for your convenience. You can quickly search those  
frequencies most commonly used by police and other agencies,  
without tedious and complicated programming. The scanner  
gives you direct access to over 40,000 exciting frequencies. Use  
your scanner to monitor:

temporary Lockout - makes it easy to temporarily lock out  
any channel or frequency. The lockout is cleared when you  
turn power off, then back on so you don’t have to remember to  
unlock the channels or frequencies later.  
triple-conversion circuitry - virtually eliminates any  
interference from IF (intermediate frequency) images, so you  
hear only the selected frequency.  
text tagging - you can name each channel, using up to 16  
characters per name.  
service Banks - frequencies are preset in 10 separate Police,  
Fire/Emergency, Ham, Marine, Railroad, Civil Air, Military Air, CB  
Radio, FRS/GMRS/MURS, and Racing banks to make it easy to  
locate specific types of calls and search any or all of these banks.  
Priority scan with do not disturb - lets you program one  
channel in each bank (10 in all) and then have the scanner check  
each channel every 2 seconds while it scans the banks so you  
don’t miss transmissions on those channels. Do-Not Disturb  
keeps the scanner from interrupting transmissions during  
receiving.  
Priority Plus scan - you can set the scanner so it scans only the  
priority channels.  
scan/search delay/resume - controls whether the scanner  
pauses at the end of the transmission to wait for a reply. You can  
set the Delay time for each Channel, Close Call Search, Custom  
Search, and Service search. You can also set a negative delay  
where the scanner stops on transmissions for a set time then  
automatically resumes.

scanning Basics  
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 BC125AT.  
What is scanning?  
Unlike standard AM or FM radio stations, most two-way  
communications do not transmit continuously. Your BC125AT  
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.  
 
15  
What is searching?  
The BC125AT 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 store it into one of the banks. If not, you can  
continue to search.  
understanding scanning  
What is CTCSS/DCS?  
Your scanner can monitor systems using a Continuous Tone  
Coded Squelch System (CTCSS) and Digital Coded Squelch (DCS)  
system, which allows the squelch to open only when the tone  
you have programmed with a specific frequency is received  
along with a transmission.  
CTCSS and DCS are sub-audible tone signaling systems  
sometimes referred to as PL or DPL (Motorola’s trademarked  
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 sub-audible  
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 “talkto the repeater.  
 
16  
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 frequency. The stations  
might even interfere with each other to the point where it is  
impossible to clearly receive any of the stations. Your scanner  
can code each received frequency with a specific sub-audible  
CTCSS or DCS frequency or code. 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.  
Refer to the Reference section of this manual for tables showing  
the available 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:  
Aircraft  
Amateur radio  
FRS/GMRS users  
Many business radio users  
 
17  
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.

listen to, the 500 channels are divided into 10 channel storage  
banks containing 50 channels each. You could use each channel  
storage bank to group frequencies by department, location,  
area of interest, or any other way you prefer. You can listen to  
any or all of the banks by using the number keys to turn them  
on or off.  
Service Search Banks  
The scanner is preprogrammed with many of the frequencies  
allocated to Police, Fire/Emergency, Ham, Marine, Railroad, Civil  
Air, Military Air, CB radio, FRS/GMRS/MURS, and Racing services.  
There are 10 banks allocated for these searches that can be used  
just like the channel storage banks to search these frequencies  
in Service Search mode.  
Custom Search Banks  
Custom Search Banks let you program and search 10 custom  
search ranges. During custom search, the scanner starts  
searching with the lowest frequency in the search range you  
select to the highest frequency in the range. You can search any  
or all of these ranges by turning each search bank on or off just  
like channel storage banks in Search mode.

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 rubber antenna.  
To improve the scanner’s reception, use an optional external  
antenna designed for multiband coverage. (You can purchase  
this type of antenna at a local electronics store). If the optional  
antenna has no cable, use 50 ohm coaxial cable for lead-in. An  
adapter plug might be necessary for the optional antennas.  
Use an optional mono 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.  
connecting the antenna  
1. Align the slots around the antenna's connector with the  
tabs on the scanner's BNC connector.  
 
20  
2. Slide the antenna's connector down over the scanner's  
connector.  
3. Rotate the antenna connector's outer ring clockwise until it  
locks into place.  
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. If it is less than 50 feet,  
use RG-58. You can get a BNC adapter at local electronics stores.  
connecting an earPhone/headPhone  
For private listening, you can plug a 1/8-inch (3.5 mm) mini-  
plug earphone or stereo 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

adJusting the BeLt cLiP  
The factory-attached belt clip makes it easier to carry the  
scanner. Use a Phillips screwdriver to adjust (loosen) the  
mounting screws or remove the belt clip completely.  
PoWering the scanner  
You can power the scanner using alkaline (ALK) non-  
rechargeable batteries (not supplied) or the included Nickel  
Metal-Hydride (Ni-MH) rechargeable batteries. [Uniden provides  
a USB cable to charge the Ni-MH batteries on initial installation  
and to recharge them through your computer (or through a  
power adapter that provides USB charge power (not included,  
but available at many retailers).]  
Inside the battery compartment is a switch to set the unit to  
either ALK or Ni-MH.  
WARNING! non-rechargeable batteries can get hot or burst  
if you try to recharge them  
CAUTIONS:  
BATT  
When  
flashes in the display and the scanner beeps  
every 15 seconds, recharge or replace the batteries.  
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.

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 search 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 50 channels.  
You can scan the channel storage banks to see if there is activity  
on the frequencies stored there.

cLose caLL  
Using the Close Call Feature  
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  
tunes to that frequency.  
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. and you can also set the frequency bands where  
you want the scanner to look for transmissions.  
The scanner also automatically stores the last 10 hits received  
into a temporary bank called "Close Call Hits" in any Close  
Call mode. The hits go away when you cycle power. You can  
also store these temporary frequencies into channel storage  
banks.  
Close Call 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.  
 
57  
Close Call works better with some types of transmissions than  
others. It might not correctly display frequency information  
for transmitters using a highly directive antenna (such as an  
amateur radio beam antenna), if there are many transmitters  
operating at the same time in the same area, or if the transmitter  
is a broadcast television station.

Weather oPeration  
Your scanner has been primarily designed as a multi-band,  
general services scanner. While it incorporates a weather alert  
ability as one of its features, we recommend that you not use  
the scanner as your sole means for receiving emergency alerts.  
Your local electronics retailer can supply a selection of weather  
radios that are dedicated to weather service monitoring. Such  
radios can be more dependable for this application.  
searching For a Weather Broadcast  
To monitor a weather channel, press Func then 3(WX) to view  
the Weather menu.  
Scroll to Weather Scan and press Pgm/E.  
 
63  
The upper line displays WX Scan and the lower line displays  
the scanning frequency with the channel number and the  
modulation.  
The scanner starts scanning the preprogrammed weather  
frequencies, and stops on the first good signal. Generally, there  
will be one channel of the seven that you will receive best. If  
this station is weak, turn the Scroll Control to check for other  
weather broadcasts in your area.  
Note 1: NOAA broadcasts are continuous broadcasts. You only lose  
reception if you move out of a coverage area. If the signal is lost, the  
scanner resumes searching for a weather transmission.  
Note 2: You cannot lock out weather frequencies.  
Weather aLert standBY  
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 scans the weather  
channels, but does not play the channel’s audio.  
To turn Weather Alert Standby on or off, press Func then  
3(WX) to view the Weather menu.  
Scroll to Weather Standby and press Pgm/E.  
The upper line displays WX Alert Standby and the lower  
lines display the channel number with the frequency and  
modulation.  
When the scanner detects the Weather Alert Tone (1050Hz), the  
scanner goes into Hold mode, immediately sounds a Weather  
 
64  
Alert siren and displays WX Alert Warning. This siren sounds as  
long as the Weather Alert Tone (1050Hz) is broadcasted.  
Pressing any key stops the siren, opens the squelch, then  
monitors the Weather channel.  
To exit Weather Alert Standby mode, press Scan.  
Weather aLert PrioritY  
Enabling this setting assigns priority to weather alert scanning  
no matter what else the radio might be doing. Checking the  
weather channel every 5 seconds for a 1050Hz tone assures you  
of the latest occurrence of a NOAA warning. (Default = O)  
1. To turn Weather Alert Priority on or off, press Func then  
3(WX) to view the Weather menu.  
2. Scroll to Alert Priority and press Pgm/E.  
3. Scroll to select WX Priority On or Off and press Pgm/E to  
save and return to the Weather menu.  
4. Press Scan or Srch/Svc to exit.  
While Weather Alert Priority is active, WX appears in the display.  
If no carrier is on any Weather channel, the scanner displays No  
WX Reception WX Priority Off and turns Weather Alert Priority  
off.

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. Birdies are especially  
present at the 16MHz level (Internal CPU clock).  
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  
 
72  
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.
