The FCC Wants You To Know
This scanner has been tested and found to comply
The FCC Wants You To Know
with the limits for a scanning receiver, pursuant to
Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful
interference in a residential installation. This scanner
generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance
with the instructions, may cause harmful
interference to radio communications.
However, there is no guarantee that interference will
not occur in a particular installation. If this scanner
does cause harmful interference to radio or
television reception, which can be determined by
turning the scanner on and off, you are encouraged
to try to correct the interference by one or more of
the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the scanner
and the receiver
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1) This device may not cause harmful interference,
and 2) this device must accept any interference
received, including interference that may cause
undesired operation.
Scanning Legally
Your scanner covers frequencies used by many
different groups, including police and fire departments,
ambulance services, government agencies, private
companies, amateur radio services, military
operations, pager services, and wireline (telephone
and telegraph) service providers. It is legal to listen to
almost every transmission your scanner can receive.
The FCC Wants You To Know
7
BC92XLT Paper OM.fm Page 8 Tuesday, August 24, 2004 3:56 PM
However, there are some transmissions that you
should never intentionally listen to. These include:
• Telephone conversations (cellular, cordless, or
other private means of telephone signal
transmission)
• Pager transmissions
• Any scrambled or encrypted transmissions
According to the Electronic Communications Privacy
Act (ECPA), you are subject to fines and possible
imprisonment for intentionally listening to, using, or
divulging the contents of such a conversation unless
you have the consent of a party to the conversation
(unless such activity is otherwise illegal). This
scanner has been designed to prevent the reception
of cellular telephone transmissions and the
decoding of scrambled transmissions. This is done
to comply with the legal requirement that scanners
be manufactured so they are not easy to modify to
pick up these transmissions. Do not open your
scanner’s case to make any modifications that could
allow it to pick up transmissions that are illegal to
monitor. Modifying or tampering with your scanner’s
internal components or using it in a way other than
as described in this manual could invalidate your
warranty and void your FCC authorization to operate it.
In some areas, mobile use of this scanner is
unlawful or requires a permit. Check the laws in your
area. It is also illegal in many areas (and a bad idea
everywhere) to interfere with the duties of public
safety officials by traveling to the scene of an
incident without authorization.

Understanding Scanning
This section provides you with background on how
Understanding Scanning
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
BC92XLT.
What is Scanning?
Unlike standard AM or FM radio stations, most twoway communications do not transmit continuously.
Your BC92XLT 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 BC92XLT 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
14
BC92XLT Paper OM.fm Page 15 Tuesday, August 24, 2004 3:56 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
• FRS/GMRS 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
GMRS/FRS radios. The range is typically 1-8 miles,
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
15
BC92XLT Paper OM.fm Page 16 Tuesday, August 24, 2004 3:56 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 25-mile 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. The included
conventional frequency guide will give you a good
head start on the other part of what you need to
know – what frequencies have interesting content.
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. Here are a few useful sites:

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. You might also try changing the
height or angle of the telescoping antenna.
• 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 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./
