FEATURES
Your Radio Shack PRO-2040 100Channel Programmable Home Scanner lets you in on all the action! This
scanner gives you direct access to
over 30,000 exciting frequencies that
include police and fire departments,
ambulance and transportation services, and amateur radio. You can
select up to 100 channels to scan,
and you can change your selections
at any time.
The secret to your scanner’s ability to
scan so many frequencies is its custom-designed microprocessor — a tiny, built-in computer.
Your scanner also has these features:
H

Using Vehicle Battery Power
To power your scanner from your vehicle’s battery power, you need a DC
power cord (such as Radio Shack
Cat. No. 270-1533).
Cautions:
• Your vehicle must have a 12-volt
DC, negative-ground electrical
system.
• The recommended DC power
cord supplies 12 volts and de livers at least 500 milliamps. The
center tip on the barrel plug is

CONNECTING AN
ANTENNA
You can connect eit her the supplied
telescoping antenna or an optional
antenna.
Telescoping Antenna
To attach the telescoping antenna,
simply screw it into the hole on top of
your scanner.
The antenna’s length controls its
sensitivity. Adjust the length of the
telescoping antenna as follows for
the best reception.
29-54 MHz Extend all 3 seg-
ments
108-174 MHz Extend only 2 seg-
ments
Optional Outdoor Antenna
The supplied antenna is usually adequate for strong, local signals. However, for the best results in receiving
weaker, more distant signals on all
bands, you can attach an optional
outdoor antenna (not supplied), such
as a mobile, telescoping, multi-band,
or outdoor base antenna.
Warning: When installing or removing an outdoor antenna, follow all
cautions and warnings included with
the antenna.
Notes:
• This scanner uses a BNC
antenna connector. If the coaxial
cable’s connector does not fit

Radio Shack store sells a complete line of outdoor antennas,
adapters, BNC connectors, and
mounting hardware.
• Always use 50-ohm coaxial
cable to connect an outdoor
antenna. For lengths under 50
feet, use RG58 (Cat. No. 278-
1314) or RG8/M (Cat. N o. 278-
1313). For lengths over 50 feet,

20-414 .fm Page 10 Wednesday, A ugust 4, 1999 11:12 AM
For the best performance, consider
the following when deciding on an
outdoor base antenna and its location:
• The location of the external
antenna should be as high as
possible.
• The external antenna and
antenna cable should be as far
away as possible from sources
of electrical noise (appliances,
other radios, and so on).
• The external antenna sh ould be
vertical.
Mount the antenna following the instructions supplied with the antenna
and its mounting hardware, then follow these steps to connect an external antenna.
1. Route the antenna cable to the
scanner and connect it to the
ANT
jack on the back of the
scanner.

Listening Safely
To protect your hearing, follow these
guidelines when you use an earphone or headphones.
• Do not listen at extremely high
volume levels. Extended highvolume listening can lead to permanent hearing loss.
• Set the volume to the lowest setting before you begin listening.
After you begin listening, adjust
the volume to a comfortable
level.
• Once you set the volume, do not
increase it. Over time, your ears
adapt to the volume level, so a
volume level that does not
cause discomfort might still
damage your hearing.
Traffic Safety
Do not wear an earphone or headphones while operating a motor vehicle or riding a bicycle. This can
create a traffic hazard and is illegal in
some areas.
Even though some earphones are
designed to let you hear some outside sounds when listening at normal
volume levels, they still present a
traffic hazard.

UNDERSTANDING THE
SCANNER’S MEMORY
You can store up to 110 frequencies
into your scanner’s memory. You
store each frequency into either a
memory called a cha nnel, or a temporary memory called a monitor. This
scanner has 1 00 channel memories
and 10 monitor memories.
Channel-Storage Banks
To make it easier to identify and select the channels you want to listen
to, channels are divided into 10 channel-storage banks of 10 channels
each. Use each channel-storage
bank to group frequencies, such as
the police department, fire department, ambulance services, or aircraft
(see “A Guide to the Action Bands”).
For example, the police department
might use four frequencies, one for
each side of town. You could program the police frequencies starting
with Channel 1 (the first channel in
Bank 1) and program the fire department starting with Channel 11 (the
first channel in Bank 2).
Monitor Memories
The scanner has 10 monitor memories. You can use these memories to
temporarily store frequencies while
you decide whether or not to store
them into channels. This is handy for
quickly storing an active frequency
when you search through an entire
band. You can manually select these
memories, but you cannot scan
them. See “Searching F or and Tem porarily Storing Active Frequencies.”
When you are in the monitor mode,
one of the memory numbers (1-10)
appears to the right of the MON indicator. The numbe r i ndicates the current monitor memory.

FINDING BIRDIE
FREQUENCIES
Birdies are operating frequencies

broadcasts on the same frequencies
and make them difficult or impossible

You can manually store up to 100 frequencies into your scanner’s channels. Radio Shack sells some goo d
references for active frequencies,
such as “Police Call Radi o G uide I ncluding Fire and Em ergency Services,” “Official Maritime Frequency
Directory” and “Official Aeronautical
Frequency Directory.”
Radio Shack updates these directories every year, so be sure to get a
current copy. If you do not have a reference to frequencies in your area,
you can use a limit or direct search to

A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered by your sc ann er is mainly “lineof-sight.” That means you usually
cannot hear stations that are beyond
the horizon. During the summer
months, you might be able to hear
stations in the 30-50 M Hz range located several hund re d o r ev en t housands of miles away. This is because
of summer atmospheric conditions.
This type of reception is unpredictable but often very interesting!

FREQUENCY CONVERSION
The tuning location of a s tation c an be expressed in frequency (k Hz or M Hz ) or
in wavelength (meters). The following information can help you make the necessary conversions.
1 MHz (million) = 1,000 kHz (thousand)
To convert MHz to kHz, multiply by 1,000:
9.62 MHz × 1000 = 9620 kHz
To convert from kHz to MHz, divide by 1,000.
2780 kHz ÷ 1000 = 2.780 MHz
To convert MHz to meters, divide 300 by the number of megahertz.
300 ÷ 7.1 MHz = 42.25 meters
