PRECAUTIONS
Before you use this scanner, please read and observe the follcwing:
■ WARNING'
Uniden DOES NOT represent this unit to be
waterproof. To reduce the risk of fire or electrical
shock, DO NOT expose this unit to rain or moisture.
■ IMPORTANT!
Be sure to use only the supplied earphone, or a
stereo headset of the proper impedance (32£i). Use
of an incorrect earphone or stereo headset may be
potentially hazardous to your hearing.
■ WARNING:
Set the Volume to a comfortable audio level coming
from the speaker before plugging in fhe supplied
earphone or a stereo headset of the proper
impedance (32il). 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 may
be particularly true of the type of earphone that is
placed in the ear canal.
■ NICKEL-CADMIUM BATTERY WARNING
• This equipment contains a Nickel-Cadmium Battery.
• The Nickel-Cadmium Battery contained in this
equipment may explode if disposed of in a fire.
• Do not short circuit the battery.
• Do not charge the Nickel-Cadmium Battery used
in this equipment with any other AC
Adaptor/Charger other than the one designed to
charge this battery (AAD-2500U). Using another
charger may damage the battery, or cause the
battery to explode.

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.
Types of Communication
You will be able to monitor communication such as:
» Police and fire department {including rescue and
paramedics)
» Weather broadcasts
» Business/industrial radio
» Motion picture and press relay
» Utility
» Land transportation frequencies, such as trucking firms,
buses, taxis, tow trucks, and railroads
» Marine and amateur (ham radio) bands
» Air band
And many more in the following 9 Bands:
Frequency Range Steps Mode Transmission

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.
