frequency where searching starts from.

Channel-Storage Banks - the scanner has 3 banks.
You can store up to 200 frequencies into the banks.

Selectable Scan Delay - delays scanning from 0 to
5 seconds according to your setting 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 (3 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.

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 10 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 “Installing
and Replacing Batteries” on Page 14 and
“Connecting the Antenna” on Page 16 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
UBC30XLT.

What is Scanning?

Unlike standard AM or FM radio stations, most two­way communications do not transmit continuously.
Your UBC30XLT 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 UBC30XLT 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

10

UB333 Paper OM reduced size.fm Page 11 Friday, June 3, 2005 1:43 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

11

UB333 Paper OM reduced size.fm Page 12 Friday, June 3, 2005 1:43 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.

Installing and Replacing Batteries

You can power your scanner using three AA alkaline
batteries.

1. Make sure the power is turned off.

2. If the belt clip is attached, remove it (See
page 18).

3. Slide the battery compartment cover.

Setting Up Your Scanner

14

UB333 Paper OM reduced size.fm Page 15 Friday, June 3, 2005 1:43 PM

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

5. Replace the cover.

Using Rechargeable Batteries

You can also use three rechargeable batteries
(Ni-MH) to power your scanner. Before you use
rechargeable batteries, make sure the batteries are
fully charged.

Setting Up Your Scanner

15

UB333 Paper OM reduced size.fm Page 16 Friday, June 3, 2005 1:43 PM

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.

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.

Setting Up Your Scanner

16

UB333 Paper OM reduced size.fm Page 17 Friday, June 3, 2005 1:43 PM

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

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.

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 3 channel­storage banks. You can scan the channel-storage
banks to see if there is activity on the frequencies
stored there.

and VHF High band.

The number programmed into each bank depends
on your choice.
For example, You may program 70 channels for FM
Radio band bank, 110 channels for Air band bank
and 20 channels for VHF High band bank. Or, it is
also possible to program 200 channels for only Air
band.

Care and Maintenance

Keep the scanner dry. If it gets wet, wipe it dry
immediately. Use and store the scanner only in
normal temperature environments. Handle the
scanner carefully: do not drop it. Keep the scanner
away from dust and dirt, and wipe it with a damp
cloth occasionally to keep it looking new.

General Use

• 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 ------ 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

34

UB333 Paper OM reduced size.fm Page 35 Friday, June 3, 2005 1:43 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 L/O to lock out the channel, then press Scan
to resume scanning.
