Introduction
Thank you for purchasing a Uniden UBC30XLT
Handheld Scanner. The scanner is versatile,
compact, and easy to use.
You can program up to 200 frequencies into the
scanner's memory. The scanner lets you scan
transmissions and is preprogrammed with service
banks and search banks for your convenience.
You can quickly search those frequencies most
commonly used in Air band, FM radio and VHF
without tedious and complicated programming.
Use your scanner to monitor:
• Air band
• FM Radio
• VHF High band

Feature Highlights
MEMORY CHANNEL SCAN - lets you scan the
channel memory frequency.
FREQUENCY SEARCH MODE - specifies the
frequency where searching starts from.
Channel-Storage Banks - the scanner has 3 banks.
You can store up to 200 frequencies into the banks.
Selectable Scan Delay - delays scanning from 0 to
5 seconds according to your setting before moving
to another channel, so you can hear more replies
that are made on the same channel.
Lock-Out Function - lets you set your scanner to
skip over specified channels or frequencies when
scanning or searching.
Priority Channels - lets you program one channel
in each bank (3 in all) and then have the scanner
check that channel every 2 seconds while it scans
the bank, so you do not miss transmissions on those
channels.
Monitor - Opens the squelch to receive all the signal
regardless of its strength.
Key Lock - lets you lock the scanner's keys to help
prevent accidental changes to the scanner's
programming.
Display Backlight - makes the scanner easy to
read in low-light situations.
Flexible Antenna with BNC Connector - provides
adequate reception in strong signal areas and is
designed to help prevent antenna breakage.
Or, you can connect an external antenna for better
reception.
Memory Backup - keeps the frequencies stored in
memory for an extended time if the scanner loses
power.

AUTO POWER OFF - allows the scanner to
automatically become low power consumption mode
of microcomputer, if the battery voltage is lower then
voltage where battery low alert is occurred. Once
power off feature starts, LCD is turned off and all
operations are not effective.
Key Confirmation Tones - the scanner sounds a
tone when you perform an operation correctly, and
an error tone if you make an error.
Battery Low Alert - warns you when battery power
gets low.
About This Manual
The screen displays used in this manual are
representations of what might appear when you use
your scanner. Since what you see depends on the
frequencies for your area and the settings you select,
you might notice some differences between what is
in this manual and what appears on your scanner.
To get the most from this manual, review the
contents to become familiar with the basic functions
available. If you are new to scanning, be sure to
read “Understanding Scanning” on Page 10 for a
quick background on the technology behind the
hobby. The first thing you’ll need to do is install
batteries in the scanner. Then you need to connect
the included antenna to the scanner. See “Installing
and Replacing Batteries” on Page 14 and
“Connecting the Antenna” on Page 16 if you need
any help doing this.

Understanding Scanning
This section provides you with background on how
scanning works. You don’t really need to know all of
this to use your scanner, but some background
knowledge will help you get the most from your
UBC30XLT.
What is Scanning?
Unlike standard AM or FM radio stations, most twoway communications do not transmit continuously.
Your UBC30XLT scans programmed channels until
it finds an active frequency, then stops on that
frequency and remains on that channel as long as
the transmission continues. When the transmission
ends, the scanning cycle resumes until the scanner
receives another transmission.
What is Searching?
The UBC30XLT can search for active frequencies.
This is different from scanning because you are
searching for frequencies that have not been
programmed into the scanner. When you select
frequency bands to search, the scanner searches
for any active frequency within the lower and upper
limits you specify. When the scanner finds an active
frequency, it stops on that frequency as long as the
transmission lasts. If you think the frequency is
interesting, you can program it into one of the banks.
If not, you can continue to search.
Conventional Scanning
Conventional scanning is a relatively simple concept.
Each group of users in a conventional system is
assigned a single frequency (for simplex systems) or
two frequencies (for repeater systems). Any time one
of them transmits, their transmission always goes
out on the same frequency. Up until the late 1980’s
Understanding Scanning
10
UB333 Paper OM reduced size.fm Page 11 Friday, June 3, 2005 1:43 PM
this was the primary way that radio systems
operated.
Even today, there are many 2-way radio users who
operate using a conventional system:
• Aircraft
• Amateur radio
• PMR users
• Broadcast AM/FM/TV stations
• Many business radio users
When you want to store a conventional system, all
you need to know is the frequencies they operate
on. When you are scanning a conventional system,
the scanner stops very briefly on each channel to
see if there is activity. If there isn’t, the scanner
quickly moves to the next channel. If there is, then
the scanner pauses on the transmission until it is over.
Simplex Operation
Simplex systems use a single frequency for both
transmit and receive. Most radios using this type of
operation are limited to line-of-sight operation. This
type of radio is frequently used at construction job
sites, and with inexpensive consumer radios such as
PMR radios. The range is typically 1.5-12 km,
depending upon the terrain and many other factors.
Repeater Operation
Repeater systems use two frequencies: one transmits
from the radio to a central repeater; the other
transmits from the repeater to other radios in the
system. With a repeater-based system, the repeater
is located on top of a tall building or on a radio tower
that provides great visibility to the area of operation.
When a user transmits (on an input frequency), the
signal is picked up by the repeater and retransmitted
(on an output frequency). The user’s radios always
Understanding Scanning

UB333 Paper OM reduced size.fm Page 12 Friday, June 3, 2005 1:43 PM
listen for activity on the output frequency and
transmit on the input frequency. Since the repeater
is located very high, there is a very large line of
sight. Typical repeater systems provide coverage
out to about a 40 km radius from the repeater
location.
Where To Obtain More Information
By itself, this manual really only provides part of
what you need to know to have fun scanning – how
to program and use the scanner.
Information On The Internet
The Internet is a great source for current frequencies
and information about scanning.
Many web sites have lists of frequencies for your area.
You can use a search engine to find and use them.
Make a list of the agencies you want to listen to,
then look up the frequencies and systems used by
those agencies.
