Feature Highlights
Chain Search - lets you enter personal search
bands in 10 locations and search all locations in a
chain of frequency bands.
Triple-Conversion Circuitry - virtually eliminates
any interference from IF (intermediate frequency)
images, so you hear only the selected frequency.
Channel-Storage Banks - the scanner has 10 banks.
You can store up to 20 frequencies into each bank
(for a total of 200 frequencies), so you can more
easily identify calls.
Two-Second Scan Delay - delays scanning for
about 2 seconds 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 (10 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.
Two Service Banks - frequencies are preset in
separate Aircraft and FM CB to make it easy to
locate specific types of calls.
Key Lock - lets you lock the scanner's keys to help
prevent accidental changes to the scanner's
programming.
Direct Access - lets you directly access any
channel.
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.
Two Power Options - let you power the scanner
using internal batteries or external AC power using
the included AC adapter.
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 11 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 “Using
Internal Batteries” on Page 15 and “Connecting the
Antenna” on Page 18 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
UBC92XLT.
What is Scanning?
Unlike standard AM or FM radio stations, most twoway communications do not transmit continuously.
Your UBC92XLT 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 UBC92XLT 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
11
UB324 Paper OM reduced size.fm Page 12 Wednesday, February 2, 2005 8:01 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

12
UB324 Paper OM reduced size.fm Page 13 Wednesday, February 2, 2005 8:01 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.

Setting Up Your Scanner
These guidelines will help you install and use your
new scanner:
• If your scanner receives interference or electrical
noise, move the scanner or its antenna away
from the source.
• To improve the scanner’s reception, use an
optional external antenna designed for multiband coverage. (You can purchase this type of
antenna at a local electronics store). If the
optional antenna has no cable, use 50-70 ohm
coaxial cable for lead-in. A mating plug might be
necessary for the optional antennas.
• Use an optional mono earphone or mono
headset with proper impedance for private
listening. Read the precautions on the inside
front cover of this Owners Manual.
• Do not use the scanner in high-moisture
environments such as the kitchen or bathroom.
• Avoid placing the scanner in direct sunlight or
near heating elements or vents.
Using Internal Batteries
You can power your scanner using supplied
rechargeable AA batteries.
Using Rechargeable Batteries
Before you use Ni-MH or Ni-Cd batteries, you must
charge them.
The scanner has a built-in circuit that lets you
recharge Ni-MH or Ni-Cd batteries while they are in
the scanner. To charge the batteries;
1. Make sure the power is turned off.
2. Slide the battery compartment cover.
Setting Up Your Scanner
15
UB324 Paper OM reduced size.fm Page 16 Wednesday, February 2, 2005 8:01 PM
3. Install two batteries in the compartment as
indicated by the polarity symbols (+ and -)
marked inside.
Removesticker and
set switch for use of
Alkaline batteries.
4. Replace the cover.
5. Connect the supplied AC adapter to the
scanner's DC 6V to charge the batteris. (See
“Using AC Power” on page 18.)
Using Non-rechargeable Batteries
You can also use two alkaline batteries to power
your scanner. Before you use alkaline batteries, you
must remove the sticker in the compartment and
move the switch to REG. ALK. BATT position.
