Precautions

Before you use this scanner, please read and observe the following:

EARPHONE WARNING!

Be sure to use only the recommended optional monaural earphone

(EP009). You may also use a 32Ω stereo headset. Use of an incorrect earphone or stereo headset may be potentially hazardous to your hearing. The output of the phone jack is monaural, but you will hear in both headphones of a stereo headset.

Set the volume to a comfortable audio level coming from the speaker before plugging in the monaural earphone or a stereo headset of proper impedance (32Ω ). Otherwise you might experience some discomfort or possible hearing damage if the volume suddenly becomes too loud because of the Volume Control or Squelch Control setting. This may be particularly true of the type of earphone that is placed in the ear canal.

WARNING!

Uniden does not represent this unit to be waterproof. To reduce the risk of fire or electrical shock, do not expose this unit to rain or moisture.

Terminology

What is Scanning?

Unlike standard AM or FM radio stations, most two-way communications do not transmit continuously. The

UBC 245XLT scans the channels you program until it finds an active frequency.

Scanning stops on an active frequency and remains on that channel as long as the transmission continues. When the transmission ends, the scanning cycle resumes until another transmission is received.

What is Searching?

The UBC 245XLT can search each of its 10 bands to find active frequencies. This is different from scanning because you are searching for frequencies that have not been programmed into your scanner. You can choose between two speeds while searching. Turbo Search, a new feature for Uniden scanners, can search the VHF FM bands at up to 300 channels per second.

What is Trunk Tracking?

Conventional scanning is a simple concept. You enter a radio frequency in your scanner’s memory which is used by someone you want to monitor. So when your scanner stops on a frequency, you usually know who it is, and more importantly, you can stop on a channel and listen to an entire conversation. This type of scanning is easy and fun.

As the demand for public communications has increased, many public radio users don’t have enough frequencies to meet their needs, and this has created a serious problem. Trunking radio systems solve this problem.

In a trunked radio system, which contains up to 28 different frequencies, radio users are divided into groups, often called talk groups, and these talk groups are assigned specific IDs. When someone in a talk group uses their radio, a brief burst of data is broadcast before each transmission. The trunking system computer uses this data to temporarily assign each radio in a talk group to an available frequency. If the group using a frequency stops broadcasting or pauses between replies for a few seconds, they are removed from the frequency so another talk group can use it.

Sharing of the available public service frequencies, or trunking, allows cities, counties, or other agencies to accommodate hundreds of users with relatively few frequencies. Following a conversation on a trunked system using a scanner is difficult, if not impossible, because when there’s a short break during the conversation you’re monitoring, it’s possible that the talk group will be assigned to a completely different frequency in the trunked system. This type of scanning is difficult and frustrating.

TrunkTracker™ changes this! Not only does your new UBC 245XLT scan channels like a conventional scanner, it actually follows the users of a trunked radio system. Once you know a talk group’s ID, you won’t miss any of the action.

If you’re a new scanner enthusiast, you may want to read the first part of this manual and use your scanner in conventional mode before you begin trunk tracking. Understanding scanning fundamentals and its terminology will make trunk tracking much easier. But if you’re already an experienced scanner operator, you may want to go to

Trunk Tracking on page 36 now.

Feature Highlights

■Trunk Tracking — Follow UHF High Band UHF 800/900 MHz trunked radio systems just as if conventional two-way communications were used.

■Multi-Track — Track more than one trunking system at a time and scan conventional and trunked systems at the same time.

■300 Channels — Program one frequency into each channel. You must have at least one channel programmed to use the Scan mode.

■10 Bands, 10 Banks — Includes 10 bands, with Aircraft and 800 MHz. 10 banks with 30 channels each are useful for storing similar frequencies to maintain faster scanning cycles or for storing all the frequencies of a trunked system.

■66 MHz-956 MHz — Indicates the range of frequencies that can be searched within the bands of your scanner.

Note: The frequency coverage is not continuous.

■10 Priority Channels — You can assign one priority channel in each bank. Assigning a priority channel allows you to keep track of activity on your most important channel(s) while monitoring other channels for transmissions.

■Preprogrammed Service (SVC) Scan — Allows you to toggle through preprogrammed police, railroad, aircraft, marine, and UHF CB frequencies.

■Unique Data Skip — Allows your scanner to skip unwanted data transmissions and reduces birdies.

■Memory Backup — If the battery completely discharges or if power is disconnected, the frequencies programmed in your scanner are retained in memory.

■Manual Channel Access — Go directly to any channel.

■LCD Back Light — An LCD light remains on for 15 seconds when is pressed.

■Autolight — Automatically turns the light on when it finds a transmission.

■Battery Save — In manual mode, your scanner automatically reduces its power requirements to extend the battery™s charge.

■Attenuator — Reduces the signal strength.

■SmartScanner™* — Automatically program your UBC245XLT with all the frequencies and t… talk groups for your local area by accessing our national database with your PC or just an external modem. (No PC required)

■Turbo Search — Increases the search speed to 300 steps per second. This applies only to transmission bands with 5 kHz steps.

* the SmartScanner feature is not yet utilised in Australia and New Zealand but may become available in the future.

Programming Tips

nGroup similar frequencies into adjacent channels.

For example, program police frequencies in channels 1 through 10 and fire/emergency into channels 11 through 20, and so on.

nPut the frequency that you listen to the most or the most important frequency into a Priority channel.

nTo quickly program a series of channels, start with the lowest number channel.

For example, when you are programming five new frequencies into Channels 4 through 8, start with Channel 4. After you finish programming a channel, press or to go to the next higher channel.

nWrite down your programmed channels and frequencies in some convenient place in case the scanner memory is lost.

RF Attenuation Feature

The UBC 245XLT comes with an RF Attenuation feature. If you’re near an unusually strong signal source, the signal may overload the scanner. The scanner may stop repeatedly on that signal and miss other transmissions.

The RF Attenuation feature works in all modes and attenuates (reduces) the incoming signal strength by about 15 dB, preventing stronger signals from overloading the scanner.

To turn RF Attenuation on: 1. Press ATT.

2. You hear a beep, and ATT appears in the display.

Now all incoming signal strength is reduced.

To turn RF Attenuation off, just press ATT again. The ATT icon goes out.

Setting the Delay Mode

A delay can be set for each programmed channel so that when scan or search stops on a channel there is a brief pause before the scanning cycle resumes. Delay must be set for each programmed channel and it can be set when your scanner pauses during a scan or when manual mode is selected.
