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

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.
