About Your New UBC 120XLT
Tbe UBC 120XLT is a brand new stale-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 programmed 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 120XLT 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 120XLT ts 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 UBC 120XLT is
truly a Twin Turbo Scanner.

Feature Highlights
♦ Twin Turbo Scan & Search —This lightning-fast
technology enables the UBC 120XLT 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 not totally continuous
from 66 MHz to 512 MHz.)
♦ 10 Priority Channels You can assign one Priority
Channel in each Bank. Assigning priority channels
allows you to keep track of activity on your most
important channel(s) while monitoring other channels for
transmissions. (Priority Channels are initially set in the
first channel in each Bank.)
♦ Weather Channels Lets your scanner function as a
weather information radio.
Note: Currently, the Weather Service is not provided in
Australia. ' .
♦ Unique Data Skip Allows the scanner to skip over
unwanted data transmissions 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 UBC 120XLT comes with a rechargeable Nickel-Cadmium
Battery Pack. When fully charged, this Battery Pack will
supply up to 12 hours of dependable use. (With the Squelch
control in “closed” position.)
Before using the UBC 120XLT for the first time, or whenever
the LOW BATTERY Indicator appears on the LCD display, I
you should fully charge the Battery Pack.
Note: When the Battery Pack is low, the Low Battery
Indicator will start to blink. Afterabout tOminutes, the
scanner will shut itself off to prevent the battery from
becoming completely discharged.
Before charging, you must first install the Battery Pack
according to the steps below.
Charging the Battery Pack
1.
Plug the AC Adaptor/Charger {AAD-2500U} into the
Charging Jack located on the Left side of the
UBC 120XLT . (You can use the scanner while it is
charging,)
WARNING! Use only an AACh2500U AC 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 reversed polarity can
cause overheating or damage to f/te circuitry.
2. Plug the AC Adaptor/Charger into a standard AC outlet.
To fully charge the battery, leave the Adaptor/Charger
connected for 14 to 16 hours.
When charging is complete, disconnect the Adaptor/
3.
Charger from the AC outlet and from the Battery Pack.
Note: Dtscorjnecf the AC AdaptorX/harger from the unit
during a power failure.
Mounting the Flexible Antenna
Place the end of the antenna onto the BNC connector on top
of the scanner and turn clockwise until tight.
10
Page 13
Installing the Belt Clip
Place the Belt Clip on
the mounting area on
the back of the
scanner, making sure
the holes in the clip
line up with the
threads in the back of
the scanner.
2. Insert the 2 screws into the corresponding holes and
tighten.
CAUTION: Do not tighten the screws too tight. You could
damage the case or clip.
Using the Earphone
The PHONE jack at the top of the UBC 120XLT is a standard
3.5mm stereo phone jack. You can use either the supplied
earphone, ora stereo headset. The output of this jack is
monaural audio, but you will hear it in both headphones of a
stereo headset.
IMPORTANT!
Be sure to use only the supplied earphone, or stereo headset
of the proper impedance (32ÎÏ.) Use of an incorrect earphone
or stereo headset may be potentially dangerous to your
hearing.
I
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 is particularly true of the type of earphone that
is placed in the ear canal.
11
Page 14
Operation Overview
Note; Before operating the UBC^20XU for Ню first tíme,
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-Off/Voiume
Control clockwise until you hear a click. Turn the
Volume Control a small amount clockwise to a low
listening level.
3. 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.
4. Readjust the volume to a comfortable listening level.
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, a much
stronger signal is required to open the squelch. If squelch
is set on a point clockwise from the threshold, you will hear
a constant sound (noise, if no signal is present.) The
scanner will not scan.
The UBC 120XLT has 100 memory channels, each of which
can be programmed to store one frequency. The channels are
divided into ten 10-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 alt 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.

SCN PRI
■ SEARCH The Search function is d//ferenffrom Scan.
When you select a frequency band to search, the
scanner searches for any active frequency within the
lower and upper limits you specify. When an active
frequency is found, the scanner stops on that frequency
as long as the transmission lasts. 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 search cycle resumes.

Birdies
All scanners are subject to receiving undesired signals or
birdies. If your scanner stops during SEARCH Mode and no
sound is heard, it may be receiving a birdie. Birdies are
internally generated signals inherent in the electronics of the
scanner. Use the Search Skip feature to skip the unwanted
frequencies.
Proper Care of Your Scanner
Use only an AAD-2500U AC Adaptor/Charger, (or one of the
optional Cigarette Lighter Power Cords listed on page 26)
with your scanner.
Do not leave the AC Adaptor/Charger plugged in for long
periods.
Avoid placing the scanner in direct sunlight or near heating
elements or vents.
Also, do not subject the scanner to continuous sub-zero
temperatures. If the scanner is exposed to temperatures
below -20‘'C or above 60“C, the liquid crystal display may
temporarily cease to function properly, or can become
permanently damaged.
