About Your New UBC 220XLT
The UBC 220XLT is a brand new state-of-the-art information
radio with autornatic scanning capabaiities. It can store
frequencies such as poiice, fire/wnergency, marine, air,
ceiiuiar, amateur, and other communications into 10 banks
of 20 channeis each. And you can scan aii 200 channeis at
super fast Turbo Scan speed.
With the UBC 220XLT, you can search for frequencies at fast
speed. You can aiso search V.H.F. frequencies at super fast
Turbo speed.
What is Scanning?
Uniike standard AM or FM radio stations, most two-way
communications (iisted below) do not transmit continuously.
The UBC 220XLT 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 220XLT 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 220XLT can search each of 10 bands to find active
frequencies. This is different from scanning, because you can
search for frequencies that have not been programmed into
your UBC 220XLT. 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 220XLT is searching for active frequencies, it is
in “SEARCH Mode” or TURBO SEARCH Mode." When you
stop the search with (Ж^, it is in “SEARCH HOLD Mode"
With both Turbo Scan and Turbo Search, your UBC 220XLT is
truly a Twin Turbo Scanner,

Feature Highlights
♦ Twin Turbo Scan & Search —This lightning-fast
technology enables the UBC 220XLT 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 220XLT.
♦ 200 Channels You can program each of these memory
channels to store one frequency.
♦ 10 Bands, 10 Banks Includes 10 Bands, wrtth Aircraft,
Cellular and 800 MHz. 10 Banks of 20 channels each are
useful for storing similar frequencies in order to maintain
faster scanning cycles.
^ 66 MHz - 956 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 956 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.
I
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 typicaliy 14 days, when
the Battery Pack is removed from the scanner.

Operation Overview
Note : Before operating the UBC 220XLTforthe first time,
make sure you have fuSy 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/Volume
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/us/until the
rushing noise disappears. At the squelch threshold,
any incoming signal just slightly strongerthan 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 use 220XLT has 200 memory channels, each of which
can be programmed to store one frequency. The channels are
divided into ten 20-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 slops on
an active frequency, it remains on that channel as long
as the transmission continues. When the transmission
stops, the UBC 220XLT 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.
12
When the UBC 220XLT Is on SEARCH Mode, the display will
look something like this;
SEARCH The Search function Is differenthom 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.

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
