INTRODUCTION
Your new Radio Shack PRO-2037 Programmable Scanner lets you in on all the action! This scanner gives you direct access to more than 31,000 fre- quencies that include police and fire
departments, aircraft communica- tions, amateur radio, and ambulance and transportation services. You can select up to 200 channels to scan and you can change your selection at any time.
The secret to your scanner's ability to scan so many frequencies is its cus- tom-designed microprocessor-a tiny,
built-in computer. Your scanner also has these special
features:
Hyperscan - scans 25 channels per
second and searches 50 frequencies
per second.
Headphones Jack - lets you con-
nect a pair of headphones or an ex- ternal speaker.
Two-Second Channel Scan Delay
- delays scanning for 2 seconds be- fore moving to another channel so you can hear more replies.
Lockout Function - keeps selected channels from being scanned so you can skip over them.
Priority Channel - checks a chan-
nel you select every 2 seconds to
keep you from missing important calls.
AM/FM Mode - automatically se-
lects the most common reception type for the band you are scanning, and
lets you override the selection. ATT Switch - reduces the scanner's
sensitivity to strong local signals.
Memory Backup - keeps channel frequencies stored in memory for up to 1 hour during a power loss.
Liquid-Crystal Display - shows the
selected channel and frequency.
Triple Conversion Superhetero-
dyne - eliminates any interference
from IF (Intermediate Frequency) im-
ages, so you only hear the selected
frequency. Ten Channel-Storage Banks - let
you store 20 channels in each of ten banks to group channels so calls are easier to identify.
Monitor Memories - let you tempo- rarily save up to ten channels you lo-
cate during a frequency search.

PREPARATION
This scanner is primarily designed for use in the home as a base station. You can place it on a desk, shelf, or table.
Your scanner's front feet fold up or down. Adjust them to give you the best view of the display.
CONNECTING THE ANTENNA
To attach the supplied telescoping an- tenna, simply screw it clockwise into the hole on the scanner's top.
The scanner's sensitivity depends on the antenna's length and various envi-
ronmental conditions. For the best re- ception of the transmissions you want to hear, adjust the antenna length.
Frequency Antenna Length
30-174 MHz
380 - 512 MHz extend 2 segments
806 - 960 MHz collapse fully
extend fully
(1 segment only)
Connecting an Optional Antenna
The telescoping antenna is adequate for strong local signals. But, for im-
proved reception, you can connect a
multi-band outdoor antenna (not sup-
plied) to the scanner. Your local Radio
Shack store sells a variety of anten-
nas. Choose the one that best meets
your needs.
When deciding on an outdoor base
antenna and its location, consider the
following:
The location of the antenna should be as high as possible.
The antenna and antenna cable should be as far as possible from sources of electrical noise (appli- ances, other radios, and so on).
The antenna should be vertical for
the best performance.
6
Page 7
To connect an optional antenna, always
use 50-ohm coaxial cable, such as RG- 58 or RG-8. For lengths over 50 feet, use RG-8 low-loss dielectric coaxial ca- ble. If the coaxial cable's connector does not fit in the also need a PL-259-to-BNC antenna plug adapter, such as Cat. No. 278-
120. Your local Radio Shack store car- ries a wide variety of coaxial antenna
cable and connectors.
Follow the mounting instructions sup- plied with the antenna. Then route the antenna cable to the scanner, and connect it to the
back of the scanner.

CONNECTING POWER
You can power your scanner from either of these sources:
Standard AC power
Vehicle battery power (using an op- tional DC adapter)
The memory backup circuit begins to function a few minutes after you con-
nect the scanner to AC or DC power. If a power failure occurs or if the power cord is disconnected, this cir-
cuit protects information in the scan-
ner's memory for about 1 hour.
Connecting AC Power
Plug the scanner's AC power cord into a standard AC outlet.
Caution:
sharp edges or moving objects.
Warning: Use extreme caution when you install or remove an outdoor antenna. If the antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches a power line, contact with the antenna, mast, cable, or guy wires can cause electrocution and death. Call the power company to re- move the antenna. DO NOT at- tempt to do so yourself.
Do not run the cable over
Caution:
the plug's blades are polarized and fit only one way. If the plug does not fit easily, turn it over and try again. Do
not force the plug into the AC outlet.
To prevent electric shock,

Connecting DC Power
You can power your scanner from your vehicle's cigarette-lighter socket using a DC adapter (Radio Shack Cat. No. 270-1533).
Cautions:
The vehicle must have a 12-volt, negative ground electrical system.
You must use a DC adapter that supplies 12 volts and delivers at least 500mA and its plug must cor- rectly fit the back of the scanner. The recom- mended adapter meets these specifications. using an adapter that does not meet these specifica- tions could seriously damage the scanner or the adapter.
Insert the DC adapter's small barrel plug into the scanner's back. Then plug the other end of the DC adapter into your vehi- cle's cigarette-lighter socket.

Listening Safely
To protect your hearing, follow these
guidelines when you use head- phones.
Set the volume to its lowest setting before you begin listening. After you put on the headphones, adjust the volume to a comfortable listen-
ing level.
Do not listen at extremely high-vol-
ume levels. Extended high-volume listening can lead to permanent hearing loss.
Do not increase the volume once you establish a comfortable listen-
ing level. Over time, your ears adapt to the volume level, so a vol- ume level that does not cause dis-
comfort might still damage your
hearing.

Traffic Safety
Do not wear headphones while oper- ating a motor vehicle or riding a bicy- cle. This can create a traffic hazard and is illegal in some areas.
Even though some headphones are designed to let you hear some out- side sounds when listening at normal volume levels, they still present a traf- fic hazard.
CONNECTING AN
EXTERNAL SPEAKER
You can connect an optional extemal speaker with a1/s-inch plug to the scanner. Use an 8-ohm external speaker capable of handling over 5 watts of power, such as Cat. No. 21-
549.

UNDERSTANDING MEMORY
You can store frequencies into either a permanent memory location, called a channel, or a temporary memory lo- cation, called a monitor memory. You can store up to 200 channels and 10
monitor memories.
CHANNEL-STORAGE
BANKS
To make it easier to identify and se-
lect the channels you listen to most often, channels are divided into 10 channel-storage banks (1 to 10) of 20 channels each. You can use each channel-storage bank to group fre- quencies, such as those used by the police department, fire department, ambulance services, or aircraft (see "Guide to the Action Bands").
For example, there might be three or four police departments in your area, each using several different frequen- cies. Additionally, there might be other
law enforcement agencies such as state police, county sheriffs, or SWAT teams that use their own frequencies. You could program all law enforce-
ment frequencies starting with Chan-
nel 1 (the first channel in Bank 1), then program the fire department,
paramedic, and other public safety frequencies starting with Channel 21
(the first channel in Bank 2).
MONITOR MEMORIES
The scanner also has 10 monitor
memories. You can use these memo- ries to temporarily store frequencies while you decide whether or not to save them in channels. This is handy
for quickly storing an active frequency
when you search through an entire band.
Notes:
To store a frequency into a monitor memory, you must perform a limit or direct search. See "Searching
For and Temporarily Storing Active Frequencies."
You can select monitor memories manually, but you cannot scan
them. See "Using Monitor Memo-
ries."

STORING FREQUENCIES
Good references for active frequen- cies are Radio Shack's "Police Call Radio Guide Including Fire and Emer- gency Services," "Official Aeronautical Frequency Directory," and "Maritime
Frequency Directory." We update these directories every year, so be sure to get a current copy. See also "Guide to the manual.
If you do not have a reference to fre- quencies in your area, you can use a
limit or direct search to find a trans-
mission. You can store up to 200 frequencies
into your scanner's channels. Follow these steps to store frequencies.

A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered by your scanner is mainly "Iine-of-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 MHz range located several hundred or even thousands of miles away. This is be-
cause of summer atmospheric conditions. This type of reception is unpredictable
but often very interesting!

BIRDIES
Birdies are frequencies your scanner uses when it operates. These operating fre- quencies might interfere with broadcasts on the same frequencies. If you program one of these frequencies, the scanner locks up and you hear only noise on that frequency.
If the interference is not severe, you might be able to rotate SQUELCH clockwise to cut out the birdie. The most common birdies to watch for are listed below.
Birdie Frequencies:
32.100 MHz
32.250 MHz
42.975 MHz
44.085 MHz
48.185 MHz
52.400 MHz
Note: Depending on the temperature of some of the scanner's internal compo- nents, you might hear birdies on frequencies slightly above or below the frequen- cies listed here.

CARE AND MAINTENANCE
Your Radio Shack PRO-2037 Programmable Scanner is an example of superior design and craftsmanship. The following suggestions will help you care for your scanner so you can enjoy it for years.
Keep the scanner dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that can corrode the electronic circuits.
Handle the scanner gently and carefully. Dropping it can damage cir- cuit boards and cases and can cause the scanner to work improperly.
Use and store the scanner only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, dam- age batteries, and distort or melt plastic parts.
Keep the scanner away from dust and dirt, which can cause prema- ture wear of parts.
Wipe the scanner with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong deter-
gents to clean the scanner.
Modifying or tampering with your scanner's internal components can cause a
malfunction and might invalidate the scanner's warranty and void your FCC authorization to operate it. If your scanner is not operating as it should, take it to your local Radio Shack store for assistance.
