Scanning technology has changed dramatically
over the years. The Pro-652 scanner with Object
Oriented User Interface is designed to help the
hobbyist build a collection of channels to scan:
• Start small and expand
• Organize channels and talkgroups
• Remove unwanted channels and talkgroups
What is Object Oriented Scanning?
Programming scanning receivers can be challenging,
but object-oriented programming simplifies the
process by using common conventions for scanning
concepts that have common characteristics.
A Scannable Object is any defined item that can be
scanned or monitored, including:
• Conventional, non-trunked radio frequencies
• Talkgroups used on a trunked radio system
• Radio services
• Defined searches
Because scannable objects are defined by the same
basic elements, the Object Oriented User Interface (OOUI) is designed to simplify scanning by managing
all scannable objects similarly. When you learn how
to program one type of object, you can program
other types of scannable objects as well.

Scanning Legally
FCC Statement
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 means of private telephone signal
transmission)
• Paging transmissions
• Any intentionally decoded scrambled or
encrypted transmissions
According to the Electronic Communications
Privacy Act (ECPA), 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 has been designed
to prevent reception of illegal transmissions. This
is done to comply with the legal requirement that
scanners be manufactured so 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
illegal to monitor. Doing so could subject you to legal
penalties. We encourage responsible, legal scanner
use. In some areas, mobile use of this scanner is
unlawful or requires a permit. Check the laws in your
area. It is also illegal in many areas to interfere with
the duties of public safety officials by traveling to the
scene of an incident without authorization.
This equipment has been tested and found to
comply with the limits for a scanning receiver,
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference in a residential
installation. This equipment generates, uses
and can radiate radio frequency energy and, if
not installed and used in accordance with the
instructions, may cause harmful interference
to radio communications. However, there is no
guarantee that interference will not occur in a
particular installation. If this equipment does cause
harmful interference to radio or television reception,
which can be determined by turning the equipment
off and on, the user is encouraged to try to correct
the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment
and receiver.
• Connect the equipment into an outlet on a
circuit different from that to which the receiver is
connected.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1.) This device may not cause harmful interference.
2.) This device must accept any interference
received, including interference that may cause
undesired operation.

Setup
Antenna
You scanner's antenna connects easily, or you can
use a variety of antennas, such as an external mobile
antenna or outdoor base station antenna.
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.
To connect an external antenna, follow the
installation instructions supplied with the antenna.
Always use 50-ohm coaxial cable, such as RG-58 or
RG-8 low-loss dielectric coaxial cable. You may also
need a BNC adapter.
To connect the included antenna:
1. Align the slots.
2. Rotate connector.
Your scanner’s frequency sensitivity depends on its
location and the antenna length. For best reception,
adjust the antenna’s length as follows:
WARNING: Outdoor antennas must be properly
grounded to prevent static buildup and lightning
damage. Article 810 of the National Electrical
Code, ANSI/NFPA 70, provides information about
proper grounding of the antenna mast, connection
of coaxial cable to an lightning arrestor, size of
grounding conductors, location of the lightning
arrestor and connection of grounding conductors to
grounding electrodes.
Additionally, disconnect your radio from the outdoor
antenna during electrical storm activity to prevent
damage. The diagram below provides an example of
a proper antenna grounding system.

Desktop Operation
The mounting bracket works as a desktop stand when
attached underneath the radio. Use the provided
rubber feet to prevent sliding or scratching. Do not
use the rubber feet if mounting permanently to a fixed
surface. Extra pads are provided for additional stability.
1. Attach the adhesive rubber feet to the
mounting bracket.
2. Attach the two adhesive rubber washers over
the mounting holes, between the mounting
bracket sides and the scanner’s side holes.
3. Position the bracket with the two recessed fee
toward the front of the scanner.
4. Use the two provided knobs to secure the
scanner within the mounting bracket.
Use the mounting bracket as a template to mark the
locations for the two mounting screws.
Drill holes that are slightly smaller than the screws.
Use caution not to damage wiring or components
that are located behind the mounting surface.
Using the provided screws and lock washers, attach
the mounting bracket to your vehicle.
Headphones and Speakers
You can plug headphones (not supplied) or an
amplified speaker (not supplied) with a
1/8-inch (3.5 mm) mini-plug earphone or in the
headphone jack on top of your scanner. This
automatically disconnects the internal speaker.
NOTE: Use an amplified speaker with this scanner;
Non-amplified speakers do not provide sufficient
volume for comfortable listening.
Listening Safely
To protect your hearing, follow these guidelines
when you use headphones:
Mount Installation
Attach the bracket over the radio to suspend the
scanner from above. Attach the bracket underneath
the scanner to mount it on top of a flat surface.
Your PRO-652 also fits into the included DIN-E
compatible sleeve for existing dashboard openings.
NOTE: In some cases, installation requires
specialized tools and skills. If in doubt, seek
assistance from a local car audio electronics
installation shop, or a local two-way radio dealer.
Select a location that does not interfere with driving
or with the deployment of your vehicle’s air bags.
Do not mount this or any other equipment where
deployment of the air bags might cause it to be
propelled towards passengers. If necessary, seek
advice from your automotive dealer or service shop.
1011
Set the volume to zero before putting on
headphones. With the headphones on, adjust the
volume to a comfortable level.
Avoid increasing the volume after you set it. Over
time, your sensitivity to a volume level decreases, so
volume levels that do not cause discomfort might
damage your hearing.
Avoid or limit listening at high-volume levels.
Prolonged exposure to high-volume levels can
cause permanent hearing loss.
Wearing headphones while operating a motor
vehicle can create a traffic hazard and is illegal in
most areas. Even though some headphones let you
hear some outside sounds when listening at normal
volume levels, they still can present a traffic hazard.
Exercise extreme caution!
AC Adapter
You must use a power source that supplies 12-14.4
VDC and is rated for 600 mA. Its center tip must be
set to positive and its plug must fit the scanner’s DC
13.8V jack. The supplied DC power adapter meets
these specifications. Using a DC adapter that does
not meet these specifications could damage the
scanner or the adapter.
To Connect the AC Adapter
1. Plug the
supplied
AC adapter
into the DC
13.8V jack.
2. Plug the AC
adapter into your wall outlet.
WARNING: To prevent electric shock, do not use
the AC adapter’s polarized plug with an extension
cord, receptacle, or other outlet unless you can fully
insert the blades to prevent blade exposure.
DC Power Cable
Connect the supplied DC power cable to a vehicle
power source:
1. Disconnect your battery's negative (-) terminal.
NOTE: Disconnecting your battery may reset some
devices in your vehicle, such as automotive audio
systems, navigation systems, or alarm systems.
2. Route the suppled DC power cord between a
power source and the mounting location for
your scanner.
3. Ground the power cord's black wire to your
vehicle’s chassis.
NOTE: The grounding screw must make complete
contact with the metal frame of your vehicle.
4. Connect the power cord's red wire to a voltage
source that turns on and off with the ignition
switch, such as a spare accessory terminal in
your vehicle’s fuse box.
5. Insert the power plug into the DC power jack on
the rear of the radio.
6. Reconnect the cable to the negative (-) terminal
of your vehicle’s battery.
NOTE: If your vehicle’s engine is running, you might
hear electrical noise from the engine while scanning.
This is normal.
WARNING: The DC power cord is equipped with
an inline fuse. This fuse protects your scanner and
your vehicle from damage in case of equipment
malfunction or a short circuit. Do not remove the
inline fuse holder from the DC power cord. If the
fuse blows, replace it with a 2A fuse and apply power
again. If the fuse blows again, check all wiring for
short circuits, and check the radio for a malfunction.
