Direct Search — lets you search for  
transmissions starting from a frequen-  
cy you specify.  
Attenuator — reduces the scanner’s  
sensitivity to help limit reception to  
strong, nearby transmitters.  
Count Feature — lets you keep track  
of how many times your scanner has  
stopped on a channel.  
Memory Backup — keeps stored  
channel frequencies in memory for up  
to 3 days during a power loss.  
Search Skip — lets you select up to  
50 frequencies for the scanner to skip  
during a search, so you can avoid fre-  
quencies you have already discovered  
or that have a continuous transmis-  
sion.  
CTCSS Option — with an optional  
CTCSS tone circuit board, you can  
use the Continuous Tone Coded  
Squelch System (CTCSS) to selec-  
tively listen to some business band  
and amateur radio transmissions.  
Two-Second Scan Delay — delays  
scanning for 2 seconds before moving  
to another channel, so you can hear  
more replies.  
Backlit Display — lets you easily see  
the indicators on the scanner’s dis-  
play, even at night.  
We recommend you record your scan-  
ner’s serial number here. The number  
is on the scanner’s back panel.  
Data Skip — skips data signals (non-  
modulated signals such as preamble  
signals for pagers) during scan, limit  
search, and direct search.

Your scanner has the following pre-  
programmed weather channels:  
• 162.4000 MHz (NFM)  
• 162.4250 MHz (NFM)  
• 162.4500 MHz (NFM)  
• 162.4750 MHz (NFM)  
• 162.5000 MHz (NFM)  
• 162.5250 MHz (NFM)  
• 162.5500 MHz (NFM)  
Priority Channels — checks 10 spec-  
ified channels every 2 seconds so you  
do not miss important calls.  
Automatic Modulation Mode — se-  
lects the modulation method — nar-  
row-band  
frequency  
modulation  
(NFM) or amplitude modulation (AM)  
— most often used for each band, and  
lets you manually override the preset  
mode.

Your scanner can receive all of these  
bands:  
SCANNING LEGALLY  
Your scanner covers frequencies  
used by many different groups includ-  
ing police and fire departments, ambu-  
lance services, government agencies,  
private companies, amateur radio ser-  
vices, military operations, pager ser-  
vices, and wireline (telephone and  
telegraph) service providers. It is legal  
to listen to almost every transmission  
your scanner can receive. However,  
there are some transmissions you  
should never intentionally listen to.  
These include:

FCC NOTICE  
• Pager transmissions  
Your scanner might cause radio or TV  
interference even when it is operating  
properly. To determine if your scanner  
is causing the interference, turn off  
your scanner. If the interference goes  
away, your scanner was causing it.  
Try to eliminate the interference by:  
• Any scrambled or encrypted  
transmissions  
According to the Electronic Communi-  
cations Privacy Act (ECPA), you are  
subject to fines and possible imprison-  
ment for intentionally listening to, us-  
ing, or divulging the contents of such a  
transmission unless you have the con-  
sent of a party to the conversation (un-  
less such activity is otherwise illegal).  
RadioShack encourages responsible,  
legal scanner use.  
• Moving your scanner away from  
the receiver  
• Connecting your scanner to an  
outlet that is on a different electri-  
cal circuit from the receiver  
• Contacting a RadioShack store for  
help  
If you cannot eliminate the interfer-  
ence, the FCC requires that you stop  
using your scanner.

PREPARATION  
Follow these steps to use AC power.  
CONNECTING POWER  
You can power your scanner from a  
standard AC outlet using the supplied  
AC adapter or from your vehicle’s bat-  
tery using an optional DC power cord.  
DC 12V  
If a power failure occurs or if the pow-  
er cord is disconnected, the scanner’s  
memory backup circuit keeps informa-  
tion in memory for up to 3 days.  
1. Insert the supplied AC adapter’s  
barrel plug into the scanner’s DC  
12V jack.  
Note: The memory backup circuit be-  
gins to protect memory within a few  
minutes after you plug in the scanner.  
2. Plug the adapter’s power module  
into a standard AC outlet.  
Using Standard AC Power  
Using Vehicle Battery Power  
Warning: Do not use the AC adapter  
with an extension cord unless the  
blades can be fully inserted.  
Use a DC power cord (not supplied),  
such as RadioShack Cat. No. 270-  
1533, to power your scanner in your  
vehicle.  
Cautions:  
Cautions:  
• The supplied AC adapter supplies  
12 volts and delivers 500 milli-  
amps. Its center tip is set to posi-  
tive, and its plug properly fits the  
scanner’s DC 12V jack. Using an  
AC adapter that does not meet  
these specifications could dam-  
age the scanner or the adapter.  
• The DC power cord you select  
must supply 12 volts and deliver  
at least 500 mA. Its center tip  
must be positive, and its plug  
must fit the scanner’s DC 12V jack.  
The recommended power cord  
meets these specifications. Using  
a power cord that does not meet  
these specifications could dam-  
age the scanner or power cord.  
• Connect the adapter to the scan-  
ner before you connect it to an AC  
outlet. Disconnect the adapter  
from the AC outlet before you dis-  
connect it from the scanner.  
• Connect the power cord to the  
scanner before you plug it into  
your vehicle. Disconnect the  
power cord from the vehicle  
before you disconnect it from the  
scanner.  
• If you have difficulty inserting the  
AC adapter’s plug, do not force it.  
Turn it over and reinsert it.

• If you use your scanner in your  
vehicle with the engine running,  
you might hear electrical noise  
from the scanner. This is normal.  
Note: Mobile use of this scanner is  
unlawful or requires a permit in some  
areas. Check the laws in your area.

Optional Outdoor Antenna  
CONNECTING AN  
ANTENNA  
The supplied antenna is usually good  
for strong, local signals. However, for  
the best results in receiving weaker,  
more distant signals on all bands, you  
can attach an optional outdoor anten-  
na (not supplied), such as a mobile,  
telescoping, multi-band, or outdoor  
base antenna.  
You can connect either the supplied  
telescoping antenna or an optional an-  
tenna to your scanner.  
Telescoping Antenna  
Warning: When installing or removing  
an outdoor antenna, follow all cautions  
and warnings included with the anten-  
na.  
The supplied telescoping antenna  
helps your scanner receive strong lo-  
cal signals. Follow these steps to in-  
stall the supplied antenna.

Note: Always use 50-ohm coaxial ca-  
ble to connect an outdoor antenna to  
your scanner. For lengths under 50  
feet, use RG-58 or RG-8/M coaxial ca-  
ble. For lengths over 50 feet, use RG-  
8, low-loss coaxial cable. If the coaxial

jack, you might also need an adapter.  
Your local RadioShack store sells a  
complete line of outdoor antennas,  
adapters, BNC connectors, and  
mounting hardware.  
Caution: This procedure clears all the  
information you have programmed  
into the scanner. Use this procedure  
only when you are sure your scanner  
is not working properly.  
For the best performance, consider  
the following when deciding on an out-  
door antenna and its location:  
• The location of the external  
antenna should be as high as pos-  
sible.  
• The  
external  
antenna  
and  
antenna cable should be as far  
away as possible from sources of  
electrical noise (appliances, other  
radios, and so on).

TESTING ALERT  
OPERATION  
For your scanner’s weather alert func-  
tion to be effective, you must place the  
scanner:  
To verify that your scanner receives  
the test alert properly, set the scanner  
to the weather alert standby mode  
(see “Using the Weather Alert Stand-  
by Mode” on Page 25) during the time  
when the test alert is broadcast in your  
area.  
• Where it can receive an emer-  
gency alert broadcast (see “Test-  
ing Alert Reception” on this page)  
• Where you can hear its alert tone  
(See “Testing the Weather Alert”  
on Page 11).  
If the test alert broadcast does not trig-  
ger your scanner’s tone, you are out of  
range of the broadcast.  
Once you determine a location that  
meets these two conditions, leave the  
scanner there for the best protection.  
Note: If you use your scanner’s  
weather alert feature when you travel,  
you cannot guarantee that an emer-  
gency alert broadcast will trigger the  
scanner in all areas.  
Testing Alert Reception  
The fact that you get clear voice re-  
ception or that the tone sounds when  
you test the weather alert does not  
guarantee that an emergency alert  
broadcast will trigger your scanner’s  
alert tone. Also, if you are in a fringe  
area, your scanner might be triggered  
by a broadcast in one area, but not be  
triggered if you place it somewhere  
else (even close by).  
Notes for Weather Alerts:  
To ensure your scanner will sound  
the alert tone when it receives an  
emergency signal, keep the  
antenna fully extended at all  
times.  
• If severe weather threatens, do  
not wait for an alert tone; turn on  
your scanner and monitor the lat-  
est weather information.  
To test for actual reception, your radio  
must receive a test or emergency alert  
broadcast. The National Weather Ser-  
vice (NWS) broadcasts a test alert ev-  
ery week on Wednesday between 11  
AM and 12 Noon. To find out the spe-  
cific test schedule in your area, con-  
tact your local National Oceanic and  
Atmospheric Administration (NOAA)  
or National Weather Service office.

scanner. This disconnects the internal  
speaker.  
Testing the Weather Alert  
Follow these steps to test the weather  
alert — to hear how it sounds and en-  
sure that the circuitry is working.  
Note: This test does not ensure that  
your scanner will sound an alert when  
the weather service transmits an  
emergency signal (see “Weather  
Alert” on Page 25). Proper operation  
is affected by the strength of the  
weather service’s signal.  
Note: Your local RadioShack store  
has a wide selection of earphones and  
headphones.  
Listening Safely  
1. Press WX.  
To protect your hearing, follow these  
guidelines when you use an earphone  
or headphone.  
2. When the scanner stops on a  
weather channel, press ALERT.  
ALERTappears on the display.  
• Do not listen at extremely high  
volume levels. Extended high-vol-  
ume listening can lead to perma-  
nent hearing loss.  
3. Press and hold PRIORITY for more  
than 2 seconds until the scanner

Traffic Safety  
INSTALLING AN  
OPTIONAL CTCSS  
TONE BOARD  
Do not wear an earphone or head-  
phones while operating a motor vehi-  
cle. This can create a traffic hazard  
and can be illegal in some areas.  
The scanner’s CTCSS (Continuous  
Tone Control Squelch System) feature  
lets you choose to listen only to trans-  
missions that transmit one of 38 stan-  
dard CTCSS tones. To use CTCSS,  
you must install an optional CTCSS  
tone board (Cat. No. 20-0031).  
Even though some earphones and  
headphones let you hear some out-  
side sounds when listening at normal  
volume levels, they still can present a  
traffic hazard.  
Cautions:  
CONNECTING AN  
AMPLIFIED EXTENSION  
SPEAKER  
• Make sure the scanner is off and  
disconnect the power before you  
install a CTCSS tone board.  
• Discharge static electricity buildup  
by touching a metal object before  
you open the scanner.  
In a noisy area, an amplified extension  
speaker might provide more comfort-  
able listening. Plug the speaker ca-

remove the two side screws on  
the scanner’s top cover and three  
screws on the bottom.  
the scanner’s  
jack. This discon-  
nects the internal speaker.  
Caution: The scanner’s speaker  
is attached to the top cover and  
the circuit board. Use care when  
you remove the top cover to not  
damage the speaker or its con-  
nector.  
Note: RadioShack stores sell an am-  
plified communications extension  
speaker.

L/O— appears when you manually  
select a locked channel or a skipped  
frequency.  
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 20 channels each.  
Use each channel-storage bank to  
group frequencies, such as the police  
department, the fire department, am-  
bulance services, or aircraft (see  
“Guide to the Action Bands” on  
Page 34).  
DLY— appears when you program a  
channel for a 2-second delay or when  
you listen to a channel that has been  
programmed with the delay feature.  
Also, the indicator appears when you  
turn on the delay feature during a limit  
or direct search or weather scan.  
WX — appears when the scanner is  
searching the weather band frequen-  
cies.  
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 then program fire department fre-  
quencies starting with Channel 21 (the  
first channel in Bank 2).  
ALERT— appears when the scanner  
is set to respond to a weather alert  
tone.  
s and t — indicate the search direc-  
tion.  
SEARCH — appears during a limit  
search (-L-also appears), direct fre-  
quency search (-d- also appears),  
weather frequency search, auto store  
mode, hold direct search (-h- also  
appears), and hold limit search (-H-  
also appears).  
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 into channels. This is  
handy for quickly storing an active fre-  
quency when you search through an  
entire band. See “Searching For and  
Temporarily Storing Active Frequen-  
cies” on Page 19.  
UNDERSTANDING  
CHANNEL-STORAGE  
BANKS  
You can store up to 210 frequencies  
into your scanner’s memory. You  
store each frequency into either a  
memory called a channel, or a tempo-  
rary memory called a monitor. This  
scanner has 200 channel memories  
and 10 monitor memories.

Locking Out Channels  
MANUALLY SELECTING  
A CHANNEL  
You can increase the effective scan-  
ning speed by locking out channels  
that have a continuous transmission,  
such as a weather channel.  
You can continuously monitor a spe-  
cific channel without scanning. This is  
useful if you hear an emergency  
broadcast on a channel and do not  
want to miss any details (even though  
there might be periods of silence) or if  
you want to monitor a specific chan-  
nel.  
Note: You can manually select the  
channels you have locked out.  
To lock out a channel, manually select  
the channel, then press LOCKOUT so  
L/Oappears on the display.  
If your scanner is scanning and stops  
at the desired channel, press MANUAL

SPECIAL FEATURES  
DELAY  
PRIORITY  
Many agencies use a two-way radio  
system that might have a period of 2  
or more seconds between a query and  
a reply. To keep from missing a reply  
on a specific channel, you can pro-  
gram a 2-second delay into any chan-  
The priority feature lets you scan  
through channels and still not miss im-  
portant or interesting calls on specific  
channels. You can program one  
stored channel in each bank as a pri-  
ority channel (up to 10 stored chan-  
nels). As the scanner scans the  
banks, it checks the priority channels  
every 2 seconds for activity.  
nel, or on frequencies during  
a
frequency search. The scanner con-  
tinues to monitor the frequency for 2  
seconds after the transmission stops  
before resuming scanning.  
Notes:  
• You cannot use the priority and  
data skip features at the same  
time.  
To program a 2-second delay:  
• If the scanner is scanning and  
stops on an active channel,  
quickly press DELAY before it con-  
tinues scanning again.  
• You cannot use the priority and  
count features at the same time.  
• You can lock out priority channels.  
If you lock out all priority channels,  
the display shows LOCOUtwhen  
you turn on the priority feature.  
• If the desired channel is not  
selected, manually select the  
channel, then press DELAY.  
• If the scanner is searching, press  
DELAY while the scanner is  
searching. DLY appears on the  
display and the scanner automati-  
cally adds a 2-second delay to  
every transmission it stops on.  
• The priority feature must be  
turned off to listen to monitor  
memories.  
• The scanner checks the lowest-  
numbered priority channels first. If  
it detects a transmission on a pri-  
ority channel, it stays on that  
channel and does not check the  
other priority channels until the  
transmission ends.  
To turn off the 2-second delay, press  
DELAY while the scanner is monitoring  
the channel or while the scanner is  
searching. DLY disappears from the  
display.

USING CTCSS  
CTCSS is frequently used when two  
different services or groups use the  
same frequencies, but are relatively  
close together. Each group sets their  
transmitters to different CTCSS fre-  
quencies, and sets their receivers to  
only let them hear transmissions that  
include the correct CTCSS frequency.

Birdie Frequencies  
Birdies are frequencies your scanner uses when it operates. These operating fre-  
quencies might interfere with broadcasts on the same frequencies. If you tune one  
of these frequencies, you hear only noise on that frequency.  
If the interference is not severe, you might be able to turn SQUELCH clockwise to  
cut out the birdie. Here are this scanner’s birdie frequencies that you might want to  
watch for:  
29.4900  
29.4950  
31.2000  
36.0450  
52.0000

469.5000  
813.4000  
820.1125  
940.9000  
993.5000  
To find the birdies in any receiver, begin by disconnecting the antenna and moving  
it away from the receiver. Make sure that no other nearby radio or TV sets are  
turned on near the receiver. Use the search function and search every frequency  
range from its lowest frequency to the highest. Occasionally, the searching will stop  
as if it had found a signal, often without any sound. That is a birdie. Make a list of all  
the birdies in your scanner for future reference.

CARE AND MAINTENANCE  
Your PRO-2045 200-Channel Direct  
Entry Programmable Scanner is an  
example of superior design and crafts-  
manship. The following suggestions  
will help you care for the PRO-2045 so  
you can enjoy it for years.  
Wipe the scanner with a  
damp cloth occasional-  
ly to keep it looking  
new. Do not use harsh  
CLEANER  
chemicals,  
cleaning  
solvents, or strong de-  
tergents to clean the  
scanner.  
Keep the scanner dry. If  
it gets wet, wipe it dry  
immediately.  
Liquids  
Modifying or tampering with your  
scanner’s internal components can  
cause a malfunction and might invali-  
date 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 Ra-  
dioShack store for assistance.  
can contain minerals  
that can corrode the  
electronic circuits.  
Handle the scanner  
gently and carefully.  
Dropping it can damage  
circuit boards and cas-  
es and can cause the  
scanner to work im-  
properly.  
Use and store the scan-  
ner only in normal tem-  
perature environments.  
Temperature extremes  
can shorten the life of  
electronic devices and  
distort or melt plastic  
parts.  
Keep the scanner away  
from dust and dirt,  
which can cause pre-  
mature wear of parts.
