Features
Your new PRO-650 Desktop Scanner lets you scan conventional transmissions 
and is preprogrammed with search banks of the most common frequencies 
used by public service agencies. Service Banks are accessed by pressing a 
one-touch search key—no complicated programming required. 
Your new scanner gives you direct access to over 26,000 frequencies, including 
those used by police and fire departments, FM broadcast, ambulance services, 
aircraft, and amateur radio services.
Your PRO-650 scanner also has these special features:
Service Banks – easily locate types of calls by searching preprogrammed 
frequencies in separate marine, fire/police, aircraft, ham, FM broadcast, and 
weather banks.
Display Backlight – makes the display easy to read in low-light situations.
Lock-out Function – skip over specified channels or frequencies when 
scanning or searching.
Ten Channel-Storage Banks – group and store 20 channels in each bank (200 
total channels).
Tune – tune to new and unlisted frequencies starting from a specified 
frequency.
SAME/FIPS Weather Alert – displays the weather event and sounds an alert 
for the specific cities or counties you choose.
Memory Backup – frequencies remain stored in memory for an extended time 
even without power.
Scan Delay – delays scanning for two seconds before moving to another 
channel in order to hear  replies.
Priority Channel – set the scanner to check one channel every two seconds 
while scanning.

5
Features
Data Cloning – transfer the programmed data to another PRO-650 scanner.
Real-time Signal Strength Indicator – shows relative strength of received 
signals.
Liquid-Crystal Display (LCD) – easy to view and change programming 
information.
Telescopic Antenna – provides good reception of strong local signals. You can 
also connect an external antenna for improved reception of distant or weak 
signals.
Your PRO-650 scanner can receive these bands:

Features
Understanding Your Scanner
Once you understand a few simple terms used in this manual and familiarize 
yourself with your scanner’s features, you can put the scanner to work for you. 
Simply determine the type of communications you want to receive, then set the 
scanner to scan them.
A frequency is the receiving signal location (expressed in kHz or MHz). To find 
active frequencies, use the search function or consult an online resource such 
as www.radioreference.com. 
When you find a frequency, you can store it into a programmable memory 
location called a channel, which is grouped with other channels in a channel-
storage bank. You can then scan the channel-storage banks to see if there is 
activity on the frequencies stored there. Each time the scanner finds an active 
frequency, it stays on that channel until the transmission ends.
Channel Storage Banks
To make it easier to identify and select the channels you want to listen to, your 
scanner divides the channels into 10 banks (1 to 10) with 20 channels each, 
for a total of 200 channels. You can use each channel-storage bank to group 
frequencies, such as those used by the police department, fire department, 
ambulance services, or aircraft.
For example, you could program the frequencies used by your local police 
department starting with Channel 1 (the first channel in bank 1) and program 
the fire department frequencies starting with Channel 21 (the first channel in 
bank 2).
Service Banks
The scanner is preprogrammed with the frequencies allocated to marine, fire/
police, aircraft, ham radio, FM broadcast and weather services. This is handy for 
quickly finding active frequencies instead of searching through an entire bank 
(see “Service Bank Search” on page 17).

Setup
Connecting the Antenna
To attach the supplied telescopic antenna:
1.   Insert the antenna in the hole on the top of the scanner.
2.  Turn the antenna clockwise to tighten.
Connecting an Outdoor Antenna
To connect an external antenna, follow the installation instructions supplied 
with the antenna. Use 50-ohm coaxial cable to connect your scanner to the 
outdoor antenna. For lengths between 50 and 100 feet, use RG-8X low-loss 
dielectric coaxial cable. For lengths over 100 feet, use RG8. You also may need 
a BNC adapter (available at your local RadioShack store).
w Warning: Use extreme caution when installing or removing 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, touching the antenna, mast, cable, or 
guy wires can cause electrocution and death. Call the power company to remove 
the antenna. DO NOT attempt to do so yourself.
Connecting Headphones
For private listening, you can plug Çinch (3.5 mm) mini-plug earphones or 
headphones (not supplied), into the HEADPHONE jack on the back of the 
scanner. This automatically disconnects the internal speaker.
Listening Safely
Do not wear headphones, earphones, or earbuds while operating a motor 
vehicle or riding a bicycle. This can create a traffic hazard and could be illegal 
in some areas. 
To protect your hearing, follow these guidelines:
•  Do not listen at high volume levels. Extended high-volume listening can 
lead to permanent hearing loss.
•  Set the volume to the lowest setting. Then turn on your audio device and 
adjust the volume to a comfortable level.
•  Avoid increasing the volume. Your ears will adapt to the volume level, so a 
level that does not cause discomfort could still damage your hearing.
Connecting an Extension Speaker
In a noisy area, an amplified extension speaker (available from your local 
RadioShack store or www.RadioShack.com), might provide more comfortable 
listening. Plug the speaker cable’s Ç inch (3.5 mm) miniplug into your scanner’s 
HEADPHONE jack.
n Note: Use an amplified speaker with this scanner. Non-amplified speakers 
do not provide sufficient volume for comfortable listening.

Receiving Alerts for Specific Areas
About SAME Signals
The National Weather Service precedes each weather alert with a digitally 
encoded SAME (Specific Area Message Encoding) signal, then a 1050 Hz tone. 
The SAME signal includes a FIPS (Federal Information Processing Standard) 
code and an event code that corresponds with the type of alert being sent. 
The FIPS code format is:
Subdivisions State County
0-9
(0=entire area)
01-50
(00=all states)
XXX
(000=all counties)
Example: 048439
(0=All; 48=Texas; 439=Tarrant County)
A current list of FIPS codes is located at www.NWS.NOAA.gov/NWR.
SAME Standby Mode
In SAME Standby mode, your scanner monitors weather channels for SAME 
alerts for up to seven areas you specify by entering the FIPS codes. 
To program your scanner for SAME Standby mode:
1.   Press  .
2.   Press PGM to access the FIPS code entry mode.

22
Basic Operation
3.   Use e or d to select the desired FIPS code storage location.
4.   Use the number keys to enter the FIPS code, then press ENT to store the 
code. 
5.   Repeat steps 3-4 for all the FIPS codes that you wish to store. 
6.   Press   to exit FIPS code entry mode. The scanner displays F showing that 
FIPS codes are enabled.
7.   Press PRI/ALERT to initiate SAME Standby mode. The scanner displays F 
[1-7]CH StAndby. 
The scanner will monitor weather channels for alerts with matching FIPS codes. 
To exit SAME Standby mode, press PRI/ALERT again.
n Notes:
•   Press L/O during step 4 to lock-out FIPS entries;  L /0  appears in the display. 
Press L/O again to enable FIPS entries;  L/0  disappears.
•  If you do not enter any FIPS codes, or if your FIPS codes are locked out, 
when you enter SAME Standby mode the scanner receives alerts and 
warning messages for all receivable areas.
•   The scanner sounds an alert when it receives the SAME code. To stop the 
alert and ready the scanner to receive a new alert signal, press any key.
•  If you do not stop the alert within five minutes, the alert stops and the 
scanner beeps every ten seconds. If the scanner receives a new weather 
alert after five minutes, it sounds the new alert. 
Testing the Weather Alert and Beep Tone
1.   To test the weather alert, press and hold ENT for more than 2 seconds 
while F [1-7]CH StAndby appears on the display.
   The display indicates the type of message, and the scanner sounds an alert 
or series of beeps. The beeps automatically change every 3 seconds.
2.   Press any key to stop testing.
Skywarn
Many areas of the country have amateur radio repeaters that have been 
designated as “Skywarn” repeaters. During times of severe weather, these 
repeaters are used to relay reports of severe weather directly to meteorologists 
at a local National Weather Service forecast office. Using the Skywarn feature 
in your scanner, you can easily jump to your local Skywarn frequency and 
monitor these reports, in many cases hearing about severe weather in your area 
instantly as it occurs.
1.  Before using this feature, you must program the Skywarn frequency into 
channel 200 (see “Programming Known Frequencies into Channels” on page 16). 

23
Basic Operation
2.  To activate Skywarn, press and hold   /   for about two seconds. 
3.  The scanner jumps to channel 200 and displays  . 
n Note: 
•  If no frequency is programmed in the Skywarn channel, No ProG appears.
•  Refer to www.radioreference.com to find Skywarn frequencies in your area. 
Setting Delay
To avoid missing a reply in conversations, a two-second delay is automatically 
set for each channel. The scanner stops for two seconds after a transmission 
ends before it resumes scanning or searching. DLY appears on the display 
when the delay function is active.
To turn delay on:
•  If the scanner is scanning and stops on an active channel, quickly press 
•/DELAY before it resumes.
•  If the desired channel is not selected, manually select the channel, then 
press •/DELAY.
•  If the scanner is searching, press •/DELAY. DLY appears and the scanner 
adds a two-second delay to every transmission it stops on in that bank.
To turn delay off:
Press •/DELAY while the scanner is monitoring a channel or frequency. DLY 
disappears.
Locking Out Channels and Frequencies
You can increase the scanning or search speed by locking out channels or 
frequencies that have a continuous transmission, such as control channels, 
weather channels, or birdie frequencies.
Press L/O when the scanner stops on a channel or frequency while scanning 
or searching. The scanner locks out the channel/frequency then continues 
scanning/searching.
To manually lock-out a channel, select the channel then press L/O.  L/0  appears 
in the display.
n Notes:
•   Your scanner automatically locks out empty channels.
•   You can still manually select locked-out channels.

Troubleshooting
The scanner is not working at all.
•  The AC or DC adapter might not be connected. Be sure the adapter’s barrel 
plug is fully inserted into the DC 9V jack. The center tip of the adapter’s 
barrel plug must be set to positive.
The scanner does not receive any stations or reception is poor. 
•  An antenna is not connected or is connected incorrectly. Be sure an antenna 
is properly connected to the scanner.
•  Reception may be blocked by walls or other obstructions. Try moving to a 
different area.
The scanner is on but does not scan. 
•  The squelch might not be adjusted correctly. Turn SQUELCH clockwise. 
•  Only one channel or no channels are stored. Store frequencies into more 
than one channel.
The keypad does not work. 
•  The scanner might need to be reset or initialized. Turn the scanner off then 
on again, or initialize the scanner (see “Initializing the Scanner” on page 26).
While scanning, the scanner locks on frequencies that have an unclear 
transmission.
•  Some frequencies programmed into the scanner might be the same as 
birdie frequencies. Avoid programming birdie frequencies or only listen to 
them manually.
Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created inside 
the scanner’s receiver, which may interfere with transmissions on the same 
frequencies. If you program 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 omit the birdie. 
To find the birdies in your scanner: 
1.  Disconnect the antenna and move it away from the scanner. Make sure that 
no other nearby radio or TV sets are turned on near the scanner. 
2.  Use the Tune to search every frequency range from its lowest frequency to 
the highest. Occasionally, the searching will stop as if it has found a signal, 
often without any sound. This is a birdie. 
3.  Make a list of all the birdies in your scanner for future reference.

Additional Info
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. However, there are some 
transmissions 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), as amended, 
you are subject to fines and possible imprisonment for intentionally listening 
to, using, or divulging the contents of such a transmission unless you have 
the consent of a party to the communication (unless such activity is otherwise 
illegal).
This scanner is designed to prevent reception of illegal transmissions, in 
compliance with the law which requires that scanners be manufactured in such 
a way as to not be easily modifiable to pick up those transmissions. Do not 
open your scanner’s case to make any modifications that could allow it to pick 
up transmissions that are not legal to listen to. Doing so could subject you to 
legal penalties. 
In some areas, mobile use of this scanner is unlawful or requires a permit. 
Check the laws in your area. We encourage responsible, legal scanner use.
Care
Your scanner is not waterproof. Do not expose it to rain, moisture, or extremely 
high humidity. If the scanner gets wet, wipe it dry immediately. Use and store 
the scanner only in normal temperature environments. Handle the scanner 
carefully; do not drop it. Keep the scanner away from dust and dirt, and wipe it 
with a damp cloth occasionally to keep it looking new.
