Introduction

The BC860XLT is a new state-of-the-art radio with automatic

scanning capabilities. Store frequencies into 10 banks of 10 channels

each. Scan all 100 channels at Turbo Scan speed.

What is Scanning? Unlike standard AM or FM radio stations, most two-way

communications (listed on the next page) do not transmit continuously.

The BC860XLT scans

programmed

channels at the rate of nearly

100 channels per second 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.

While the BC860XLT scans channels, it is in Scan mode. When

you stop scanning with M, it is in Manual mode.

What is Searching? The BC860XLT can search 12 bands to find active frequencies.

This gives you the opportunity to find new frequencies that have not

been programmed.

Choose between two speeds for the search feature: Normal

(100 steps per second) or Turbo Search (300 steps per second).

While the BC860XLT searches for active frequencies, it is in Search

mode or Turbo Search mode. When you stop the search with H,

it is in Search Hold mode.

Types of

Communications Monitor communications such as:

Police and fire department (including rescue and paramedics)

Aircraft

NOAA weather broadcasts (preprogrammed channels)

Business/industrial radio

Motion picture and press relay

Utility

Land transportation frequencies, such as trucking firms, buses,

taxis, tow trucks, and railroads

Marine and amateur (ham radio) bands

And many more in the following 12 Bands:

Frequency Range Transmission

29.0-29.7 MHz 10 Meter Amateur Band

29.7-50.0 MHz VHF Low band

50.0-54.0 MHz 6 Meter Amateur Band

108-137 MHz AM Aircraft

137-144 MHz Military Land mobile

144-148 MHz 2 Meter Amateur Band

148-174 MHz VHF High Band

406-420 MHz Federal Govt. Land Mobile

420-450 MHz 70 cm Amateur Band

450-470 MHz UHF Standard Band

470-512 MHz UHF “T” Band

806-956 MHz Public Service Band except Cellular Band

Feature Highlights 100 Channels – Program one frequency into each channel. You

must have at least one channel programmed to use the Scan

mode.

29 MHz - 956 MHz – Scan these frequency ranges with your

scanner. (Note: the frequency coverage is not totally continuous

from 29.0 MHz to 956 MHz.)

10 Priority Channels – Assign one Priority channel in each bank.

Keep track of the activity on most important channel(s) while

monitoring others.

Data Skip – Skip data signals and unmodulated transmissions.

Manual Channel Access – Go directly to any channel.

Memory Backup – Frequencies programmed in the channels are

retained in memory. If the power is disconnected, the memory

retains the frequencies for 7 days.

Twin TurboTM Speed – With both Turbo Scan and Turbo Search,

your BC860XLT is truly a Twin TurboTM Scanner.

Weather Scan – Use as a weather information radio.

Scanner Care &

Safety Tips Do not use the scanner in high-moisture areas such as the

kitchen or bathroom.

Do not plug the scanner into an outlet controlled by a wall switch

as prolonged periods without power causes scanner memory loss.

Avoid placing the unit in direct sunlight or near heating elements

or vents.

Included with your Scanner

☞If any items are missing or damaged, immediately contact your place of purchase.

☞Read this Operating Guide thoroughly before operating the scanner.

☞Complete and immediately mail the Registration Form. 5

Where to Obtain

More Information Before you can scan, you must program a frequency into each

channel you want to use. The “

Betty Bearcat Starter Frequency

Guide

” lists typical frequencies used around the U.S. that you may

program into the BC860XLT.

If the frequencies listed in the “

Betty Bearcat Starter Frequency Guide

”

do not work in your area, call the enclosed “Mr. Scanner” 800 number.

A Uniden representative should be able to provide you with a few

sample frequencies. Or, use the enclosed order form to purchase a

local frequency list.

The Bearcat Radio Club and other similar hobby clubs have

publications, information on computer bulletin boards, and even

contests for the radio enthusiast.

Also, your local library has more information.

Setup

Note

Extend the antenna to its full height. For UHF

frequencies, shortening the antenna may

improve the reception.

If your scanner receives strong interference or

electrical noise, move the scanner or its

antenna away from the source.

If you are operating the scanner in a fringe area

or need to improve reception, use an optional

antenna designed for multi-band coverage.

(You can purchase this type of antenna at a

local electronics store.)

If the plug at the end of the cable does not

match the antenna jack, you may need to

purchase an adapter.

Plug an optional external speaker

(ESP25, 8 ohms) into the EXT.SP jack.

Warning!

Use only the supplied AC Adapter - AC144U

Basic Operation

Note: Fold out the illustration from the Back Cover to see the Controls and Indicators while reading this Guide.

How Squelch Works

Think of “SQUELCH” as a gate. If the

gate is too low (squelch too low),

everything (all noise as well as signals)

gets through.

If the gate is set too high (squelch too

high), nothing gets through. If the gate is set just right (squelch set

properly), just the desired signals get

through.

The BC860XLT Squelch has two options. AUTO Squelch - a level preset at the factory;

and Manual Squelch, where you can set the squelch level as needed by conditions.

Setting the Squelch

Adjust VOLUME to a comfortable listening level.

Auto Squelch

AUTO is a compromise between tight

and threshold. It is a convenience for

listening to stronger signals. ➪Note: Be sure that the Squelch control

clicks

into the AUTO position.

Manual Squelch

To manually set the Squelch, you must

be in the Manual Mode.

No signal should be present when

adjusting squelch.

Press Muntil you do not hear

a signal.

Turn until hiss heard.

This lowers the “squelch gate,” allowing

all signals and noise to get through.

Turn just until hiss stops.

This raises the “squelch gate” allowing

only strong signals to get through.
