Feature Highlights

Close CallTM RF Capture Technology - you can set the scanner so it detects and provides information about nearby radio transmissions. See “Close

CallTM RF Capture Technology” on Page 34 for more information.

Pager Screen - lets you set the scanner so it does not detect pager frequencies during Close Call search.

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 10 frequencies into each bank (for a total of 100 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.

Six Service Banks - frequencies are preset in separate police, railroad, aircraft, marine, UHF CB, and AM CB banks, to make it easy to locate specific types of calls.

Police, railroad and AM CB preset frequencies in the service bank are valid for Australia ONLY. Aircraft, Marine and UHF CB preset frequencies are valid for both Australia and New Zealand.

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 UBC73XLT.

What is Scanning?

Unlike standard AM or FM radio stations, most twoway communications do not transmit continuously. Your UBC73XLT 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 UBC73XLT 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

UBC73XLT Paper OM.fm Page 12 Monday, May 14, 2007 9:13 AM

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

•PRS (UHF CB) 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 PRS (UHF CB) 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

UBC73XLT Paper OM.fm Page 13 Monday, May 14, 2007 9:13 AM

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.

You may visit the Uniden websites listed below for information regarding scanner frequencies. Click on 'Products' from the main page and then click on 'Scanning Receivers'.

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 included 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 two alkaline or rechargeable AA batteries (not supplied).

Using Non-Rechargeable Batteries

1.Make sure the power is turned off.

2.Slide the battery compartment cover.

3.Before you install alkaline or any other nonrechargeable batteries, use a pointed object such as a ballpoint pen to set REG. ALK. BATT./ NI-MH BATT. inside the compartment to REG. ALK. BATT..

UBC73XLT Paper OM.fm Page 16 Monday, May 14, 2007 9:13 AM

WARNING!

Uniden 280 Xlt Manual Transmission

Set REG. ALK. BATT./NI-MH BATT. to NI-MH BATT. only if you are using rechargeable batteries. Never attempt to recharge non-rechargeable

batteries. Non-rechargeable batteries can get hot or burst if you try to recharge them.

4.Install two batteries in the compartment as indicated by the polarity symbols (+ and -) marked inside.

Setting Up Your Scanner

16

UBC73XLT Paper OM.fm Page 17 Monday, May 14, 2007 9:13 AM

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.

5. Replace the cover.

6.When flashes and the scanner beeps every 15 seconds, replace both batteries.

Using Rechargeable Batteries

You can also use two rechargeable batteries to power your scanner. 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, set

REG. ALK. BATT./NI-MH BATT. inside the battery compartment to NI-MH BATT., install the batteries in the scanner, and connect the included external DC adapter or optional external AC adapter to the scanner's DC 6V jack (see “Using DC power” on

Page 19 and “Using AC Power” on Page 20).

Setting Up Your Scanner

17

UBC73XLT Paper OM.fm Page 18 Monday, May 14, 2007 9:13 AM

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., 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).

•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.

•For longer operation, you can also use highcapacity Ni-MH batteries to power the scanner. This type of battery takes longer to recharge. You can get high-capacity Ni-MH batteries at your local electronics store.
