PRECAUTIONS
Before you use this scanner, please read and observe the
following.
EARPHONE WARNING!
Be sure to use only a monaural earphone with this scanner. You
can also use an optional stereo headset. Use of an incorrect
earphone or mono headset might be potentially hazardous to
your hearing. The output of the phone jack is monaural, but you
will hear it in both headphones of a stereo headset.
Set the volume to a comfortable audio level coming from the
speaker before plugging in the monaural earphone or headset.
Otherwise, you might experience some discomfort or possible
hearing damage if the volume suddenly becomes too loud
because of the volume control or squelch control setting. This
might be particularly true of the type of earphone that is placed
in the ear canal.
WARNING!
Uniden does not represent this unit to be waterproof. To reduce
the risk of re or electrical shock, do not expose this unit to rain
or moisture.

UNDERSTANDING BANKS
Channel Storage Banks
To make it easier to identify and select the channels you want to
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 o.
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 o just
like channel storage banks in Search mode.

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 rubber antenna.
To improve the scanners 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.

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.

• For longer operation, you can get higher capacity Ni-MH
batteries at your local electronics store. This type of battery
takes longer to recharge.
Charging the Ni-MH Batteries
The scanner has a built-in circuit that charges the included
Ni-MH batteries when a USB cable connects it to a computer
(NOT to a USB hub) or to an AC or DC adapter that provides USB
charging power. Verify that the battery selection switch is set to
Ni-MH and that only Ni-MH rechargeable batteries are inserted
in the scanner before connecting it to your computer.
CAUTION: Never attempt to charge non-rechargeable
batteries or install non-rechargeable batteries when
the battery selection switch is set to Ni-MH. The USB
cable will only charge the batteries if the scanner is
turned o.
1. Be sure the scanner is turned o. It will recharge only if it
is turned o, even with the USB cable connecting it to a
computer.
2. Connect the included USB cable to the scanners USB port.
3. Connect the other end of the USB cable to the computer's
USB port or to an AC or DC adapter that provides USB
charging power.
NOTE: If you connect to a computer's USB port, the PC will prompt
you for the drivers for your scanner. To download and install these
drivers, go to http://info.uniden.com/UnidenMan4/BC125AT.
4. The scanner displays Charging while it charges the
batteries and Charge Complete when the Ni-MH batteries
are completely charged.

and it operates normally. If the scanner cannot immediately
determine if the batteries are good and can be charged, it
checks them and displays the battery icon. If the scanner judges
the batteries are good, the scanner starts charging and the
battery icon disappears. If it cannot regard the batteries as good
in 60 seconds, the scanner stops checking and the battery icon
blinks.

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 nd 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 nd 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.
GETTING TO KNOW THE SCANNER
If your scanner's keys seem confusing at rst, the following
information should help you understand each key's function.
Your scanner's keys have various functions labeled on the key
tops and below the keys. The keys operate in Normal mode and
Function mode. Pressing Func puts the scanner into Function
27
mode for 3 seconds and then returns to Normal mode. The
scanner displays
F
. During that 3 seconds you can press other
keys and operate that function. Pressing Func again before 3
seconds returns to Normal mode and the
F
icon disappears.
In Normal mode the
F
icon is not displayed.

When you connect your scanner to your PC, a series of screens
will appear to assist you.
USB drivers and programming software are available for
download from http://info.uniden.com/UnidenMan4/BC125AT.
PROGRAMMING CHANNELS
Now that you have congured your scanner, you are ready to
start using your scanners preprogrammed service banks, the
custom search banks, the Close Call feature, or the Weather
Scan/Alert feature. You can also program your channel
memories or re-program your 10 custom search bank memories.
Before the scanner can begin scanning, you must program a
frequency into at least one channel.
1. To select a channel, press Hold then enter the channel
number (1-500).
2. Press Pgm/E to enter the Channel menu. (You can also
press Hold and scroll to the channel; press Func then
Pgm/E.)
Note 1: Turning SCROLL CONTROL in Function mode will
allow you to select the rst channel in each bank.
Note 2: You can quickly store frequencies in Scan Hold mode
by entering the frequency and pressing Pgm/E.
3. Scroll to highlight Enter Frequency and press Pgm/E. You
will see the channel number and currently programmed
frequency. (To return to the previous screen, press . Clr.)

5. Press . Clr to return to the last screen.
The scanner automatically rounds the entered number to the
nearest valid frequency. For example, if you enter 151.473 (MHz),
your scanner accepts it as 151.475.
If you entered an invalid frequency, Out of Band appears and
the scanner beeps three times. Press . Clr and enter a valid
frequency. If you enter a frequency that has already been
entered elsewhere, the scanner displays the channel number
and Frequency Exists – Conrm? appears.

• Close Call Only - performs continuous Close Call checks
until you exit by pressing Scan or Srch/Svc.
• < Back - returns to previous menu.
4. Press Pgm/E to select and return to the Close Call menu.
If Close Call DND or Close Call Pri is selected, the Close Call icon
will display in Scan and Search modes.
Close Call Only Mode
In Close Call Only mode, the rst line displays Close Call, CC
Search scrolls from the right to the left on the second line, and
the Close Call icon blinks in the display.
59
Enabled search bands appear on the lowest line. Disabled
search bands are not displayed. The currently searched bank
number ashes.
• To turn Close Call bands on or o, use the number keys (1-5)
on the keypad.
One search band must always be enabled. If you turn o all
search bands, the scanner will display All Band Off!
• To hold on a specic band, press Hold. Turn SCROLL
CONTROL and select the band to monitor.
When the scanner nds a frequency, CCFOUND! appears in
the display. The scanner will also beep or ash the display (if
enabled) in the Close Call Alert option in the Close Call menu.
• Press any key (other than Hold) to view the displayed
frequency.
While monitoring a Close Call transmission, the scanner displays
Close Call on rst line and the monitoring frequency on the
second line.
The modulation and any CTCSS/DCS received (if enabled) will
also appear on the display.
Numbers at the bottom of the display show the enabled Close
Call bands. The currently searched band number ashes.
