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.

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 two-  
way 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

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

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 multi-  
band 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.

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.

UB324 Paper OM reduced size.fm Page 17 Wednesday, February 2, 2005 8:01 PM  
Cautions:  
Use only fresh batteries of the required size and  
recommended type.  
Always remove old or weak batteries. Batteries  
can leak chemicals that destroy electronic  
circuits.  
Do not mix old and new batteries, different types  
of batteries (standard, alkaline, or rechargeable),  
or rechargeable batteries of different capacities.  
WARNING!  
Do not connect either adapter to the scanner if non-  
rechargeable batteries (such as alkaline batteries)  
are installed in the scanner and REG. ALK. BATT./  
NI-MH BATT. is set to NI-MH BATT (this is the  
default setting with the sticker) or if you are unsure  
of the switch’s position. Non-rechargeable batteries  
will get hot and can even burst if you try to recharge  
them.  
Before you use Ni-MH or Ni-Cd batteries for the first  
time, charge them for 16 hours to bring them to a full  
charge. Discharged batteries take about 16 hours to  
fully recharge.  
Notes:  
Ni-MH batteries last longer and deliver more  
power if you occasionally let them fully  
discharge. To do this, simply use the scanner  
until it beeps every 15 seconds and  
flashes.  
To prevent damage to Ni-MH batteries, never  
charge them in an area where the temperature is  
above 113°F (45°C) or below 40°F (4°C).

UB324 Paper OM reduced size.fm Page 18 Wednesday, February 2, 2005 8:01 PM  
If you connect an external power source to the  
scanner with REG. ALK. BATT./NI-MH BATT.  
set to REG. ALK. BATT., the scanner does NOT  
charge the batteries. Make sure that you use the  
correct batteries and set REG. ALK. BATT./  
NI-MH BATT. to the correct position when you  
connect an external power source.  
Using AC Power  
You can power the scanner using the supplied 6V,  
500 mA AC adapter.  
To use the scanner on AC power, plug the AC adapter  
into DC 6V on the side of the scanner then plug the  
other end into a standard AC outlet.  
If rechargeable batteries are installed without  
removing the sticker, or, after removing,  
REG. ALK. BATT./NI-MH BATT. is set to NI-MH BATT.,  
the adapter powers the scanner and recharges the  
installed batteries at the same time.  
Connecting the Antenna  
To attach the supplied flexible antenna to the  
connector on the top of your scanner, align the slots  
around the antenna's connector with the tabs on the  
scanner's BNC connector. Then slide the antenna's

connector down over the scanner's connector and  
rotate the antenna connector's outer ring clockwise  
until it locks into place.  
Connecting an Optional Antenna  
The scanner's BNC connector makes it easy to  
connect a variety of optional antennas, including an  
external mobile antenna or outdoor base station  
antenna.  
Note: Always use 50-ohm, RG-58, or RG-8, coaxial  
cable to connect an outdoor antenna. If the antenna  
is over 15 metres from the scanner, use RG-8 low-  
loss dielectric coaxial cable. You can get a BNC  
adapter at your local electronics store.  
Connecting an Earphone/Headphone  
UBC72XLT  
For private listening, you can plug a 3.5mm mini-  
plug earphone or mono headphones (not supplied)  
into the headphone jack on top of your scanner. This  
automatically disconnects the internal speaker.  
Connecting an Extension Speaker  
In a noisy area, an optional extension speaker,  
positioned in the right place, might provide more  
comfortable listening. Plug the speaker cable's  
3.5mm mini-plug into your scanner's jack.

About Your Scanner  
We use a few simple terms in this manual to explain  
the features of the scanner. Familiarize yourself with  
these terms and the scanner's features, and you can  
put the scanner to work for you right away. Simply  
determine the type of communications you want to  
receive, then set the scanner to scan those  
communications.  
A frequency, expressed in kHz or MHz, is the tuning  
location of a station. To find active frequencies, you  
use the search function or refer to a frequency  
reference.  
Besides searching within a selected frequency  
range, you can also search your scanner's service  
banks. Service banks are preset groups of  
frequencies categorized by the type of services that  
use those frequencies.  
When you search and find a desired frequency, you  
can store it into a programmable memory location  
called a channel. Channels are grouped into  
channel-storage banks. The scanner has 10  
channel-storage banks and each bank has 20  
channels. You can scan the channel-storage banks  
to see if there is activity on the frequencies stored  
there.

Understanding Banks  
Service Banks  
The scanner is preprogrammed with all the  
frequencies allocated to the aircraft and FM CB.  
Channel-Storage Banks  
To make it easier to identify and select the channels  
you want to listen to, the 200 channels are divided  
into 10 channel-storage banks. Each bank has 20  
channels. Use each channel-storage bank to group  
frequencies, such as those for the railroad, police  
department, or aircraft.  
For example, the police department might use eight  
frequencies in your town while the railroad uses an  
additional four. You could program the eight police  
frequencies starting with Channel 1 (the first channel  
in bank 1), and program the railroad frequencies  
starting with Channel 21 (the first channel in bank 2).

Notes:  
If you entered an invalid frequency in Step 2,  
Errorappears and the scanner beeps three  
times. Enter a valid frequency.  
The scanner automatically rounds the entered  
number to the nearest valid frequency.  
For example, if you enter 28.473 (MHz), your  
scanner accepts it as 28.475.  
When you enter a frequency into a channel, the  
scanner automatically turns on the delay  
function and DLYappears. When delay is turned  
on, the scanner automatically pauses scanning

Care and Maintenance  
Keep the scanner dry. If it gets wet, wipe it dry  
immediately. Use and store the scanner only in  
normal temperature environments. Handle the  
scanner carefully: do not drop it. Keep the scanner  
away from dust and dirt, and wipe it with a damp  
cloth occasionally to keep it looking new.  
General Use  
Turn the scanner off before disconnecting the  
power.  
Always write down the programmed frequencies  
in the event of memory loss.  
If memory is lost, simply reprogram each  
channel. The display shows 000.000 in all  
channels when there has been a memory loss.  
Always press each button firmly until you hear  
the entry tone for that key entry.  
Location  
Do not use the scanner in high-moisture  
environments such as the kitchen or bathroom.  
Avoid placing the unit in direct sunlight or near  
heating elements or vents.  
If the scanner receives strong interference or  
electrical noise, move it or its antenna away from  
the source of the noise. If possible, a higher  
elevation might provide better reception.  
Also try changing the height or angle of the  
antenna.  
Cleaning  
Disconnect the power to the unit before  
cleaning.

Clean the outside of the scanner with a mild  
detergent.  
To prevent scratches, do not use abrasive  
cleaners or solvents. Be careful not to rub the  
LCD window.  
Do not use excessive amounts of water.  
Repairs  
Do not attempt any repair. The scanner contains no  
user serviceable parts.  
Birdies  
All radios can receive “birdies” (undesired signals). If  
your scanner stops during Scan mode and no sound  
is heard, it might be receiving a birdie. Birdies are  
internally generated signals inherent in the  
electronics of the receiver.  
Press L/O to lock out the channel, then press Scan  
to resume scanning.
