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.
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.
2
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.
Note: Mobile use of this scanner is
unlawful or requires a permit in some
areas. Check the laws in your area.
For your important records, please re-
cord your scanner's serial number in
the space provided. The serial num-
ber is located on the back of the
scanner.

PREPARATION
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.
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.
6
Frequency Antenna Length
30-174 MHz extend fully
380 - 512 MHz extend 2 segments
806 - 960 MHz collapse 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.

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 ANT jack, you might
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 ANT jack on the
back of the scanner.
Caution: Do not run the cable over
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.
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: To prevent electric shock,
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.
7

RESETTING AND
INITIALIZING THE
SCANNER
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 DC 13.8 V jack on 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 DC 13.8 V jack on the
scanner's back. Then plug the other
end of the DC adapter into your vehi-
cle's cigarette-lighter socket.
DC 13.8 V Jack

If the scanner's display locks up or
the scanner does not work properly
after you connect power, you might
have to reset the scanner's display or
initialize the scanner.
Resetting the Scanner's
Display
1. Turn off the scanner, then turn it on
again.
VOLUME
2. Insert a pointed object, such as a
straightened paper clip, into the
RESET hole on the back of the
scanner.
If the scanner still does not work
properly, you might have to initialize
the scanner.

Insert the headphones' plug into the
{\ jack on the front of the scanner.
Initializing the Scanner
Caution: This procedure clears all in-
formation you programmed in the
scanner's memory. Initialize the scan-
ner only when you are sure the scan-
ner is not working properly.
1. Turn off the scanner, then turn it on
again.
2. Press and hold down CLEAR and
insert a pointed object, such as a
straightened paper clip, into the
RESET hole on the back of the
scanner.
3. Release RESET. When the display
reappears, release CLEAR.
Note: You must release RESET be-
fore releasing CLEAR in order to
clear the memory.
CONNECTING
HEADPHONES
For private listening, you can connect
an optional pair of headphones with a
1 /s-inch plug to the scanner. Use
monaural heapdhones, such as Cat.
No. 20-210.
Note: Plugging in headphones auto-
matically disconnects the internal
speaker.
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.

CONNECTING AN
EXTERNAL SPEAKER
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.
10
You can connect an optional extemal
speaker with a 1 /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.
Insert the speaker cable's plug into
the EXT SPKR jack on the back of
the scanner.

UNDERSTANDING MEMORY
MONITOR MEMORIES
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).
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."

SPECIAL FEATURES
CHANGING THE AM/FM
MODE
We designed your scanner to auto-
matically select the most common re-
ceive mode for each frequency range.
The default settings are:
FREQUENCY RECEIVE
(MHz) MODE
30.000 - 54.000 FM
118.000 - 136.975 AM
137.000 -174.000 FM
380.000 - 512.000 FM
806.000 - 960.000 FM
Although the preset mode is correct in
most cases, some ham radio and mili-
tary aircraft broadcasts do not receive
in the default mode. When the scan-
ner is not set to the correct receive
mode, the broadcast might sound
weak or distorted.
To change the mode, press AMlFM.
AM or FM blinks on the display when
you override the default mode.

press DELAY until DELAY appears on
the display. When your scanner stops
on a frequency, it waits for 2 seconds
after each transmission before it re-
sumes searching.
To turn off the programmed delay on
any active channel, press DELAY
while the channel is still active. DE-
LAY disappears from the display.
LOCKING OUT A
CHANNEL
You can scan channels faster by lock-
ing out those that have a continuous
transmission, such as a weather
channel.
To lock out a channel while scanning,
press LOCK OUT when the scanner
stops on the channel. To lock out a
channel manually, manually select the
channel and press LOCK OUT until
LOCK-OUT appears on the display.
To remove the lockout from a chan-
nel, manually select the channel and
press LOCK OUT so LOCK-OUT dis-
appears from the display.
Notes:
• You can still manually select
locked-out channels.
• You cannot lock out all channels.
There must be at least one active
channel in a bank.
The priority feature lets you scan
through the programmed channels
and still not miss an important or in-
teresting call on a specific channel. To
program a stored channel as the pri-
ority channel, press PROGRAM, the
desired channel number, and then
PRIORITY.
Note: You can only select one chan-
nel as the priority channel.
To turn on the priority feature, press
PRIORITY during scanning. PRIOR-
ITY appears on the display. The
scanner checks the priority channel
every 2 seconds, and stays on the
channel if there is activity. P appears
to the left of the display whenever the
scanner is set to the priority channel.
To turn off the priority feature, press
PRIORITY during scanning until PRI-
ORITY disappears from the display.
