Feature Highlights
Close Call™ RF Capture Technology - you can set
the scanner so it detects and provides information
about nearby radio transmissions. See “Close Call™
RF Capture Technology” on Page 32 for more
information.
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.
Key Lock - lets you lock the scanner's keys to help
prevent accidental changes to the scanner's
programming.

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 12 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 16 and “Connecting the
Antenna” on Page 20 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
12
UB340ZH Paper OM reduced size.fm Page 13 Monday, September 26, 2005 2:56 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
13
UB340ZH Paper OM reduced size.fm Page 14 Monday, September 26, 2005 2:56 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
16
UB340ZH Paper OM reduced size.fm Page 17 Monday, September 26, 2005 2:56 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 batteries. (See
“Using AC Power” on page 19.)
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.
Setting Up Your Scanner
17
UB340ZH Paper OM reduced size.fm Page 18 Monday, September 26, 2005 2:56 PM
Cautions:
• Use only fresh batteries of the required size and
recommended type.
• When flashes and the scanner beeps
every 15 seconds, replace both batteries.
• 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 nonrechargeable 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.
Setting Up Your Scanner
18
UB340ZH Paper OM reduced size.fm Page 19 Monday, September 26, 2005 2:56 PM
• 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).
• 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.
Setting Up Your Scanner
19
UB340ZH Paper OM reduced size.fm Page 20 Monday, September 26, 2005 2:56 PM
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 lowloss 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 miniplug 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.
WARNING!
If you connect an external speaker to the scanner's
headphone jack, never connect the audio output line
to a power supply and ground. This might damage
the scanner.

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
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).

Special Features
Close Call™ RF Capture Technology
Your scanner's Close Call feature lets you set the
scanner so it detects then displays the frequency of
a nearby strong radio transmission. Close Call RF
capture works great for finding frequencies at
venues such as malls and sporting events. You can
set the scanner so Close Call detection works “in the
background” while you are scanning other
frequencies, turn off normal scanning while Close
Call is working, or turn off the Close Call feature and
use the scanner normally. You can set the scanner
so it alerts you when the Close Call feature detects a
frequency. You can also set the frequency band
where you want the scanner to look for
transmissions.
Unlike searching, which requires the scanner to tune
to a frequency to check for a transmission, Close
Call RF capture directly detects the presence of a
strong, nearby signal and instantly tunes to the
source’s frequency.
Notes:
• Close Call RF capture works well for locating the
source of strong local transmissions such as
mobile and handheld two-way radios in areas
with no other strong transmission sources.
However, if you are in an area with many
transmission sources (such as pager radio
transmitters, multi-use radio towers, traffic
control devices, etc.), Close Call RF capture
might not find the transmission you are
searching for, or it might find a transmission
other than the one you are searching for.
• Close Call RF capture cannot detect satellite
dishes or any transmitter with a frequency above
or below the frequency ranges listed under
“Setting the Close Call Options” on Page 33.
Special Features
32
UB340ZH Paper OM reduced size.fm Page 33 Monday, September 26, 2005 2:56 PM
• Close Call works better with some types of
transmissions than others. It might not correctly
display frequency information for transmitters

television station.

• 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.
Care and Maintenance
51
UB340ZH Paper OM reduced size.fm Page 52 Monday, September 26, 2005 2:56 PM
• 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 0/L/O to lock out the channel, then press
Scan/Src to resume scanning.
