About Your New USC 120XLT
The UBC 120XLT is a brand new state-of-the-art information
radio with automatic scanning capabilities. It can store
frequencies such as police, fire/emergency, marine, air,
amateur, and other communications into 10 banks of 10
channels each. And you can scan all 100 channels at super
fast Turbo Scan speed.
With the UBC 120XLT, you can search for frequencies at fast
speed. You can also search v.h.f. frequencies at super fast
Turbo speed.
What is Scanning?
Unlike standard AM or FM radio stations, most two-way
communications (listed below) do not transmit continuously.
The UBC 120XLT scans prOCJrammed,channels at the rate of
nearly 100 channels per second until it finds an active
frequency.
Scanning stops on an active frequency, and remains on that
channel as long as the transmission continues. When the
transmission ends, the scanning cycle resumes until another
transmission is received. Or, you can select an optional Delay
so the scanner stays on the channel for 2 more seconds after
the transmission stops, waiting for another transmission,
before resuming scanning.
While the UBC 120XL T is scanning channels, it is in "SCAN
Mode". When you stop the scanning with~, it is in "SCAN
HOLD Mode".
What is Searching?
The UBC 120XLT can search each of 9 bands to find active
frequencies. This is different from scanning, because you can
search for frequencies that have not been programmed into
your UBC 120XLT.You can choose between two speeds for
the search feature. With Turbo Search, a new feature for
Uniden scanners, you can search the v.h.f. FM bands at up to
3 times the normal speed.
When the UBC 120XL T is searching for active frequencies, it is
in "SEARCH Mode" or "TURBO SEARCH Mode." When you
stop the search with (HOlD), it is in "SEARCH HOLD Mode".
With both Turbo Scan and Turbo Search,your UBC120XLTis
truly a Twin Turbo Scanner.

Feature Highlights
. Twin Turbo Scan &Search-This lightning-fast
technology enables the UBC 120XL T to scan nearly 100
channels per second. Search speed is selectable
between 100 and 300 steps per second. (300 steps per
second only in bands with 5 KHz steps.) Because the
frequency coverage is so large (see previous section for
band listing), very fast scanning and searching are
essential. That is why we combined our latest
technology - Twin Turbo - into the UBC 120XLT.
.100 Channels You can program each of these memory
channels to store one frequency,
.9 Bands, 10 Banks Includes 9 Bands, including
Aircraft. 10 Banks of 10 channels each are useful for
storing similar frequencies in order to maintain faster
scanning cycles.
.66 MHz -512 MHz Indicates the range of frequencies
that can be searched within the bands of your scanner.
-~ (Note: The frequency coverage is nottotally continuous
~from 66 MHz to 512 MHz.)
. 0 Priority Channels You can assign one Priority
C nnel in each Bank. Assigning priority channels
allo s you to keep track of activity on your most.
impo ant channel(s) while monitoring other channels for
transm' sions. (Priority Channels are initially set in the
first chan el in each Bank.)
. Weather C nnels Lets your scanner function as a
weather inform 'on radio.
"
Note: Currently, the~ther Service is not provide' .

.Unique Data Skip Allows the scanner to skip over
unwanted datatransmissions and reduces birdies.
.Memory Backup The stored channels are retained in
memory for at least 3 days, and typically 14 days, when
the Battery Pack is removed from the scanner.

Setup
The USC 120XLT comes with a rechargeable Nickel-Cadmit
Battery Pack. When fully charged, this Battery Pack will
supply up to 12 hours of dependable use. (Withthe Squelch
control in "closed" position.) I
Before using the USC 120XL T for the first time, or whenever
the LOW BATTERY Indicator appears on the LCD display,
you should fully charge the Battery Pack.
Note: When the Battery Pack is Iow, the Low Battery
Indicator will start to blink. After about 10 minutes, the
scanner willshut itself off to prevent the battery from
becoming completely discharged.
Beforecharging, you mustfirst installthe Battery Pack
accordingto the steps below.
Charging the Battery Pack
1. Plug the AC Adaptor/Charger (AAD-2500U) into the
Charging Jack locatedon the Left side of the
UBC 120XLT .(You can use the scanner while it is
charging.)
WARNING! Useonlyan AAD-2500UAC Adaptor/
Charger, (or one of the optional Cigarette
Lighter Power Cords listed on page 26). Any
other AC Adaptor or external cord or power plug
having over-voltage or reversedpolarity can
cause overheating or damage to the circuitry.L-,
Plug the AC Adaptor/Charger into a standard AC outlet.
2.
To fully charge the battery, leave the Adaptor/Charger
connected for 14 to 16 hours.
3. When charging is complete, disconnect the Adaptor!

2. Insertthe 2 screws intothe corresponding holesand
tighten.
CAUTION: Do not tighten the screws too tight. You could
damage the case or clip.
Using the Earphone
The PHONEjack at the top of the UBC 120XLT is a standard
3.5mm stereo phonejack. Youcan use either the supplied
earphone, or a stereo headset. The output of this jack is
monaural audio,but you will hear it in both headphonesof a
stereo headset.
IMPORTANT!
Be sure to use only the supplied earphone, or stereo headset
of the proper impedance (32ft) Use of an incorrect earphone
or stereo headset may be potentially dangerous to your
hearing.
WARNING:Do not plug in the earphone or head-
phones before setting the Volume Control. You
might experience some hearing damage if the
Volume suddenly becomes too loud because of
the volume Control or Squelch Control setting.
This isparticularlytrueofthetypeofearphonethat

Operation Overview
Note: Before operating the UBC 120XL T for the first time,
make sure you have fully charged the Battery Pack.
1. Before turning on the scanner, rotate the Squelch
Control fully clockwise.
2. Turn the scanner on by rotating the On-OffNolume
Control clockwise until you hear a click. Turn the
Volume Control a small amount clockwise to a Iow
listening level.
You should hear either a "rushing" noise or some
communications. If you are monitoring a transmission,
wait until it stops before adjusting the Squelch Control.
Readjust the volume to a comfortable listening level.
3.
4.
5. Turn the Squelch Control counterclockwise just until the
rushing noise disappears. At the squelch threshold,
any incoming signal just slightly stronger than the noise
will open the squelch. Any communication that is
received will open the Squelch, and stop scanning or
Searching.
Note: If squelch is set too tight, that is, too far
counterclockwise from the threshold point, amuch
stronger signal is required to open the squelch. If squelch
is set on a point clockwise from the threshold, you will hear
aconstant sound (noise, if no signal is present.) The
scanner will not scan.
The UBC 120XL T has 100 memory channels, each of which
can be programmed to store one frequency. The channels are
divided into ten 1O-channel banks, useful for storing similar
frequencies in order to maintain faster scanning cycles.
You can monitor communication in one of two ways:
. SCAN If you have programmed channels, you can
scan all programmed channels in the selected bank(s),
except locked out channels. When scanning stops on
an active frequency, it remains on that channel as long
as the transmission continues. When the transmission
stops, the UBC 120XLT resumes scanning, If the Delay
Mode is on, the scanner remains on the same channel
for 2 more seconds, waiting for a responding
transmission. If there is no responding transmission
within 2 seconds, the scanning cycle resumes.
Any channels that are not programmed (000.0000) are
skipped during scan.

bank. You can store one frequency per channel, up to 100
channels.
Note: If appears on the display (keypad Locked),
unlock the keypad by pressing and holding (LocK)until
disappears and you hear two beeps.
There are two ways to program a channel:
. Manually select a channel and frequency, using the
numeric keypad.
. Search a band to find an active frequency, and then
directly store it into a selected channel. (See the
Search section, page 21.)

Priority Scan
The UBC 120XL T has 10 Priority Channels, 1 per Bank.
Initially, these are the first channel in each Bank. (e.g.
Channel 1, Channel 11, Channel 21, and so on.) The scanner
checks the Priority Channel(s) every 2 seconds during the
Scan cycle. If a transmission is received, the scanner will stop
at that channel. If the Priority Channel in any Bank is "locked
Out"', it will be skipped during scanning.
You can move the Priority to any other channel in a Bank as
follows:
1. Go directly to that channel using any of the methods
described above.
2. Press and hold @for at least 2 seconds. You will
hear a "beep", and P will appear on the display to the

Locking Out Channels
You may have programmed certain channels that you do not
want to hear every time you scan. These are channels that
are busy a major portion of the time, and the scanner stops at
the channel(s) often enough to interrupt the scan cycle. You
can lock Out those channels so they are not scanned.
1. Go directly to that channel using any of the methods
described above.
2. Press @. UO appears at the lower right of the
display.
That channel is now "locked Out" of the scanning cycle.
However, you can access that channel at any time using one
of the Direct Channel Access methods.
To put the channel back in the scanning cycle:
1. Go directly to the desired channel.
2. Press @. The UO indicator now disappears from
the display, and the channel is no longer "locked Out".
You can lock out any or all of the Priority Channels the same
way as other channels. If you lock out all Priority Channels
you will see this message:
