Introduction
Welcome to an exciting new world of radio scanning! Recognizing that contemporary scanning receivers
are too hard to program and use, GRE's engineers conducted extensive research to determine the
functional requirements for an entirely new scanning receiver user interface. We call this new user interface
the Object Oriented User Interface (OOUI), and it is based on the premise that, to a hobbyist, a scanner is
easiest to use if all of the things that can be scanned are handled using common conventions for interaction
between the user and the radio, at least to the extent that this is possible given that the ”things” that can be
scanned are different from one another in either subtle or major ways.
In this new user interface design, we call “things” that can be scanned Scannable Objects. Simply put, a
Scannable Object is defined as something that can be scanned or monitored. Scannable Objects include
the following:
. Conventional, non-trunked radio channels
. Trunked talkgroups used on a trunked radio system
. Service searches to search for a specific radio service
. Search ranges with upper and lower limits
. Spectrum Sweeper setups with band segments that can be enabled or disabled by the user
One of the goals of the Object Oriented User Interface is to make the scanner as easy to use as possible.
The OOUI does this by treating all Scannable Objects the same in terms of how they are created, edited,
manipulated and grouped. Once you have learned how to create and store a conventional channel, you
know most of what you need to know to create a trunking talkgroup, and so on.
While we have designed this radio to be the easiest scanning receiver in its class to program and use, we
encourage you to read this manual in its entirety so that you will fully understand all of the radio's
capabilities. However, if you consider yourself to be an experienced scanning hobbyist and are feeling
adventurous, we invite you to dive right in and get started programming your favorite “objects” into the
radio.
Features
Upgradeable CPU Firmware - keep your radio current with enhancements as they become available with
free upgrades from www.greamerica.com!
Intuitive "Object Oriented" User Interface Design is designed for ease of use, yet powerful enough to satisfy
the most sophisticated experts. Common data entry, browsing and control methods are used for
non-trunked conventional channels, trunking talkgroups, search configurations and Spectrum Sweeper
setups. The radio grows with you - you can start out with a small, easy to manage configuration, then
expand it whenever you need to.
Menu Driven Programming With Context Sensitive Help - Each menu item provides a few lines of help text
that provide assistance with programming and using the scanner.
Powerful and flexible Scan List functionality - allows you to arrange, group and scan objects according to
your preference.
Flexible Free-Form Memory Organization - memory is assigned as objects are created using a
sophisticated internal file management system. You are not constrained to traditional bank/channel
scanner memory layouts. No memory is wasted as a result of bank/channel programming constraints. The
scanner has sufficient main memory capacity to store over 1,800 conventional channels, trunking
talkgroups, search configurations and Spectrum Sweeper objects in any combination, providing ample
capacity for more sophisticated hobbyists and professionals while keeping the database size manageable
for beginners.
SKYWARN Storm Spotter Functionality - Instant access to frequencies used by storm spotter networks.
You can monitor storm conditions as they occur, and become aware of dangerous conditions before the
media or emergency management officials are able to announce them to the general public.
SAME and All Hazards Weather Alerting - Your scanner can operate in dedicated Specific Area Message
Encoding (SAME) weather alerting mode, and alert you to severe weather and other hazards in the specific
area(s) that you select, or, your scanner can check your local NOAA weather frequency periodically, even
while scanning and alert you when an All Hazards alert occurs.
Multi-System Trunking - Scans most common trunked radio system signaling formats, including Motorola,
EDACS, and LTR trunked radio networks. Both talkgroup and individual call monitoring are supported.
GRE's Exclusive Digital AGC - instantly compensates for low user audio levels that are very common on
digital systems. This makes the radio easier to listen to, and provides you with a more enjoyable scanning
experience.
LTR Home Repeater AutoMove - Takes the guesswork out of programming LTR trunking systems when the
home repeater order is not known. Enter the LTR system frequencies in any order, and the PSR-310 will
automatically move the frequencies to the proper home repeater slots as transmissions are received on the
system.
The Best Subaudible Squelch Decoder in the Scanning Industry - CTCSS and DCS subaudible squelch
coding is processed by the CPU. Provides fast and reliable decoding of subaudible squelch signaling with
squelch tail elimination.
Powerful Spectrum Sweeper - Quickly sweeps the scanner's frequency ranges for transmissions from
nearby sources. When a nearby active frequency is found, the scanner automatically tunes to that
frequency and receives the traffic.
Exclusive ALERT LED - Programmable tri-color LED can be configured to illuminate or flash when certain
objects are active. Eight user-defined colors and brightness levels can be specified from thousands of
possible combinations. Provides visual alerts when certain channels are active, e.g., blue can be used to
signal activity on your primary police channel, red for fire, etc.
Audible alarms - Programmable audible alarms can be configured to sound when certain Scannable
Objects are active. Can be used in conjunction with, or separately from, the ALERT LED described above.
High Speed PC Interface - uses GRE's 30-3290 USB cable in full duplex mode at 6 times the speed of
previous scanner models for PC transfer and 8 times the speed of previous models for radio to radio
cloning.
Real-time Signal Strength Indicator - shows relative strength of received signals.
Sleek, compact case design with large speaker is designed for one-handed operation and ease of use.
What is Object Oriented Scanning?
To put it simply, Object Oriented Scanning describes a new user interface design for scanning receivers
(the Object Oriented User Interface, or OOUI). In Object Oriented Scanning, we introduce the concept of
the Scannable Object. A Scannable Object is defined as “something that can be scanned”.
The Scannable Object concept is very important in the OOUI design. Recall that one of the more frustrating
things about current trunking scanners is that entirely different methods of programming and interacting
with the radio are used depending on whether the user is working with trunking talkgroups or conventional
channels. A method that works with one does not work well with the other. The user must learn two entirely
different “languages” for “talking to” the radio - one for trunking and one for conventional, non-trunked
frequencies.
What if it was possible to use the same basic “language” regardless of whether a user is working with
trunked talkgroups or conventional channels, such that once a user has learned how to enter a
conventional channel into memory, they already know most of what they need to know to enter a trunked
talkgroup? Or, a search range, or other “Scannable Objects”? This is how the OOUI works - the two primary
Scannable Objects, talkgroups on trunked radio systems and conventional non-trunked frequencies use
the same user interface elements.
Additionally, we include limit and service search configurations and Spectrum Sweeper configurations as
Scannable Objects. This means that it is possible to create, edit, group, scan and delete service and limit
searches, and Sweeper configurations using the same methods that are used when working with trunked
talkgroups and conventional channels.
Object Oriented Scanning also lends itself quite well to the “collector hobbyist model” we describe above.
Object Oriented Scanning makes it very easy for newcomers to the hobby or the radio to start off with a
small collection of scannable objects and expand their collection as needed later. Object Oriented
Scanning makes it easy to group Scannable Objects in Scan Lists, a powerful and flexible grouping system.
Object Oriented Scanning makes it easy to search for new frequencies or talkgroups to monitor, and add
them to existing or new Scan List groups. Object Oriented Scanning makes it very easy to delete or
deactivate objects and Scan Lists that you do not want to listen to, including a powerful temporary lockout
mode that allows you to zero in on activity associated with a specific incident, then restore your desired
configuration when the incident is over. Finally, Object Oriented Scanning makes it exceedingly easy for the
scannist to enjoy the collection of channels and talkgroups they have programmed into the scanner, and to
share them with other scannists.
A Few Things To Remember about Object Oriented Scanning
Object oriented scanning is completely different from any prior scanning receiver technology. Accordingly,
some users may find it difficult to visualize and understand how Object Oriented Scanning works. This may
be especially true for users who have become very familiar with more recent scanning receiver
technologies.
We suggest that you keep the following “OOUI Tenets” in mind as you proceed with your study of this
manual. If you find yourself confused or stuck about the basics of Object Oriented Scanning, it may be
helpful to review this section again.
1. The OOUI memory organization is nothing more than a large list of "Scannable Objects".
2. A "Scannable Object" is simply "something that can be scanned", including conventional channels,
trunking talkgroups, limit searches, service searches and Spectrum Sweeper setups.
3. In OOUI scanning, there are no "systems", "banks", "groups", "sub-groups" or "ID lists". There is simply a
very large collection of objects, each with their own attributes. Scannable Objects all exist at the same level
or hierarchy within the scanner - no single type of Scannable Object is more important than another, and
Scannable Objects do not have dependencies on or links to other Scannable Objects in order for them to
function properly.
4. The primary method of grouping the collection of objects is by mapping them to Scan Lists. Mapping a
Scannable Object to one or more Scan Lists does not change the physical location of the object in the
memory system. Even when an object is mapped to one or more Scan Lists, the object itself has not moved
nor changed from what it is - a simple, standalone object that is part of a larger collection.
About this manual
Object abbreviations used in this document
We described how your new GRE scanner utilizes an Object Oriented User Interface in the Introduction
and Overview sections of this manual. You learned that the key components of this new user interface are
the Scannable Objects, which are, of course, “things that can be scanned”. As you begin to use your new
scanner, you will notice that the object names are abbreviated so that they can easily fit into the 16
character LCD. (Imagine what the radio's display would look like if “Trunking Talkgroup Object” was spelled
out in its entirety every time it was necessary to show it in the display.)
You should take a moment and become familiar with these abbreviations now. For consistency, the same
abbreviations for the different object types are used in the radio and here in the manual.
TGRP
TGRP is used to represent a Trunking Talkgroup Object. Trunking Talkgroups are “virtual” channels that
exist on a trunked radio system. A trunked radio system is a radio system where a small group of radio
channels are automatically shared between a larger number of users and user groups. This sharing of
channels is managed automatically by a special computer, called a controller, or by other specialized
hardware. For now, all you need to know is this; if you want to monitor a talkgroup on a trunked radio
system, you must store that talkgroup's parameters in a TGRP object.
TSYS
TSYS is used to represent a Trunking System Object. A TSYS is a special object type that is used when
creating TGRP objects. A trunking talkgroup must be associated with a specific trunked radio system in
order for it to operate. There are parameters that are associated with trunking systems, such as the type of
trunked radio system technology used, the frequencies that the system uses to broadcast control data, etc.
Instead of entering these parameters over and over again every time you create a new TGRP on the same
trunked radio system, you create a TSYS object with all of the system parameters, then specify that TSYS
object for each TGRP you create on the same trunked radio system. A TSYS cannot be scanned by itself
and is not considered a Scannable Object. It is a “configuration object” that can be used over and over
again when adding talkgroups for a specified trunked radio system.
CONV
CONV is used to represent a Conventional Channel Object. A Conventional Channel Object is a regular,
non-trunked frequency used for radio communications. CONV objects are used to store the parameters for
any radio channel that is not a part of a trunked system. For example, if you want to monitor specific VHF
marine channels, they should be programmed as CONV objects. If you want to monitor your favorite
amateur radio channel, it should be stored as a CONV object. If your police or fire department uses a
channel, or channels that are not trunked, but part of a “plain old radio system”, they should be stored as
CONV objects.
LMIT
LMIT is used to represent a Search Range, or Limit Search Object. LMIT objects contain the parameters
necessary for the radio to search a range of individual frequencies between a lower and upper limit
frequency.
SRVC
SRVC is used to represent a Service Search Object. SRVC objects are further divided into Public Safety,
Aircraft, Amateur, CB, Marine, and FRS/GMRS/MURS/DOT. SRVC objects are similar to LMIT objects, but
are preprogrammed to search all frequencies associated with the selected service. For example, selecting
the Amateur SRVC search will search selected amateur radio frequency ranges in the VHF and UHF
portions of the radio spectrum.
SWPR
SWPR is used to represent a Spectrum Sweeper Object. SWPR objects contain the parameters necessary
for the radio to rapidly sweep a range of radio spectrum for strong signals from nearby transmitters.
The FCC Wants You To Know
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.
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 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.

Getting Started
First Time Startup
We believe that your new PSR-310 is so easy to use that scannists with minimal experience in the hobby
should be able to get up and running in a matter of just a few minutes. If you already know the difference
between a conventional channel and a talkgroup, or a search range and a Spectrum Sweeper, we invite
you to dive right in and set the radio up to begin scanning your first objects. If you get stuck, you can refer to
this Getting Started section, or see the relevant sections in the Detailed Menu Reference. Otherwise,
please read on and allow us to help you get acquainted to your new scanner!
WARNING: Always protect your scanner from exposure to extreme heat or cold temperatures.
WARNING: Your scanner is not waterproof. Do not expose it to rain, extreme high humidity or moisture.
WARNING: The external DC power input is designed to accept 9 VDC using a tip-positive coaxial power
plug. Do not connect the radio to external power sources that are greater than 9 VDC. Ensure that the DC
polarity is correct before connecting your radio to an external power source. Turn the radio off prior to
connecting or disconnecting external power.
Unpack the radio
Unpack your radio carefully. Save all documentation and packing materials in case it is necessary to return
your scanner for repair.
Insert the batteries
Remove the door covering the battery compartment by pressing gently where the door is marked OPEN
and sliding the door downwards until it stops, approximately 1/4”. Lift the door away from the radio. Select
the correct battery holder for the type of batteries you are going to use. Use the black battery holder for
non-rechargeable batteries, and the yellow battery holder for rechargeable batteries.
Insert four AA batteries into the holder, taking care to ensure that the batteries are inserted according to the
polarity diagram shown inside of the holder assembly. Insert the holder into the battery compartment, then
replace the battery compartment door by placing it back over the batteries and sliding it upward gently until
it locks in place.
NOTE: Two battery holders are included with your PSR-310. The black battery holder should be used with
non-rechargeable alkaline batteries. The yellow battery holder should be used with rechargeable NiMH or
NiCAD batteries. The radio will charge the batteries when the yellow holder is used in conjunction with the
supplied AC adapter or other external 9 VDC power supply rated at 500 mA. If desired, you may use
rechargeable batteries in the black holder. They will not be charged while installed in the radio.
WARNING: Never place non-rechargeable batteries in the yellow holder. Intentionally or accidentally
recharging non-rechargeable batteries will cause them to overheat, leak or explode. Dispose of
rechargeable batteries properly by taking them to an approved battery recycling facility. Many communities
offer battery recycling services - check with your local solid waste management agency.
WARNING: Always remove old or weak batteries. Batteries can leak chemicals that destroy electronic
circuits. Do not mix old and new batteries, different types of batteries (alkaline, or rechargeable), or
rechargeable batteries of different capacities. If you do not plan to use the scanner with batteries for a
month or longer, remove the batteries. Batteries can leak chemicals that can destroy electronic parts. When
you charge Ni-Cd batteries, do not over charge them. Overcharging shortens battery life.
Attach the antenna
Remove the antenna from its protective plastic wrapper. Align the slots on the antenna's BNC male
connector with the posts on the radio's BNC female connector and slide the antenna in place, then rotate
the antenna's BNC connector 1/4 turn clockwise until it snaps in place.
NOTE: If desired, you may also connect a mobile or base station antenna equipped with a BNC male
connector to the antenna connector
Turn the radio on
Rotate the top knob of the VOLUME/SQUELCH control clockwise to turn the radio on. Set both the
VOLUME and SQUELCH knobs at their mid-point (12 o'clock) position.
NOTE: While 12 o'clock is a good squelch setting to start with, it may cause your radio to miss some calls
with weak signals. You will probably want to optimize the squelch setting to set it close to threshold. To
optimize the squelch setting to be close to the best threshold, press TUNE, then rotate the squelch control
counterclockwise until a rushing sound is heard from the speaker. Rotate the squelch control clockwise just
past the point where the rushing sound stops. The squelch is now set to the optimum point. Please note the
position of the squelch control for future reference. Once the squelch setting is complete, you may press
PGM to exit TUNE mode.
Set the battery type, if necessary
By default, your new scanner is configured to use standard alkaline batteries. Specifying the proper type of
battery is necessary for proper operation of the low battery detection feature, and also enables the charge
circuit if you are using rechargeable batteries.
If you are not using alkaline batteries, you should change the battery type by following these steps:
1. Press the PGM key.
2. Press the F3 key, which should show the label GLOB immediately above it in the LCD display.
3. Press the v nine times, or until the middle line of the display reads Battery:Alkaline.
4. Press the < or > to select the type of batteries that are installed in the radio. Use Alkaline for standard
alkaline batteries, NiCad for nickel-cadmium rechargeable batteries, and NiMH for nickel-metal hydride
rechargeable batteries.
5. Press the F1 key (the SAVE softkey) to save your battery settings to the radio's configuration memory.
Low Battery Warning
Your scanner will provide two warnings when the batteries are low. The first warning will typically occur
approximately 15 to 30 minutes prior to the point where the batteries are completely depleted, and is
indicated by a solid battery icon in the top row of the LCD display. The second warning will typically occur
approximate five minutes before the batteries are completely depleted, and is indicated by a flashing
battery icon (approximately two flashes per second) in the top row of the LCD display, and an audible low
battery alert every 30 seconds.
NOTE: Actual timing of low battery warnings will depend on the age and condition of the batteries you are
using.
Battery Charge Indicator
Your scanner provides an indication when the internal battery charge circuit is active. The battery icon
briefly flashes approximately once every second when the radio is connected to external power and the
internal battery charger circuit is active.
NOTE: The “internal battery charger circuit active” indicator provides an indication that the battery charger
circuit is active, and does not provide positive indication that the batteries are actually being charged.
Batteries will not charge unless the yellow battery holder is used.
Listening Safely
To protect your hearing, follow these guidelines when you use headphones.
Set the volume to zero before putting on headphones. With the headphones on, adjust the volume to a
comfortable level.
Avoid increasing the volume once 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.
Traffic Safety
Wearing headphones while operating a motor vehicle or riding a bicycle 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!
Connecting an Optional External Antenna
The antenna connector on your scanner makes it easy to use the scanner with a variety of antennas, such
as an external mobile antenna or outdoor base station antenna.
Always use 50-ohm coaxial cable, such as RG-58 or RG-8 low-loss dielectric coaxial cable. If your
antenna's cable does not have a BNC connector, you will also need a BNC adapter. Follow the installation
instructions supplied with the antenna, route the antenna cable to the scanner, then connect it to the
antenna jack.
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.
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, you may wish to 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.
Connecting an Earphone/Headphones
For private listening, you can plug an 1/8-inch (3.5 mm) mini-plug earphone or headphones (not supplied)
in the HEADPHONE jack on top of your scanner. This automatically disconnects the internal speaker.
Connecting an External Speaker
In a noisy area, an amplified speaker (not supplied) might provide more comfortable listening. Plug the
speaker cable's 1/8-inch (3.5 mm) mini-plug into your scanner's HEADPHONE jack.
NOTE: You must use an amplified speaker with this scanner. Non-amplified speakers do not provide
sufficient volume for comfortable listening.
Using the Belt Clip
You can use the belt clip attached to the back of the scanner for hands-free carrying when you are on the
go. The PSR-310 ships with the belt clip already installed. To remove the belt clip, use your finger to
disengage the retaining catch at the top of the belt clip from the back of radio, and slide the belt clip
upwards. To install the belt clip, slide it down into the belt clip receptacle on the rear of the radio. Press
down on the belt clip until it locks in place. Slide the belt clip over your belt, pocket or waistband.
NOTE: You can order a replacement belt clip from GRE America (http://www.geramerica.com if the one
that came with your radio becomes lost or damaged.
Using AC Power
You can power the scanner using a supplied AC adaptor.
WARNING: You must use the supplied AC adaptor.
. Always connect the AC adaptor to the scanner before you connect it to AC power. When you finish,
disconnect the adaptor from AC power before you disconnect it from the scanner.
. The correct orientation for the enclosed power adaptor is in a vertical or floor-mount position.
To power the scanner using an AC adaptor, connect the plug into the scanner's PWR DC 9V jack. Then
connect the AC adaptor to a standard AC outlet.
WARNING: To prevent electric shock, do not use the AC adaptor's polarized plug with an extension cord,
receptacle, or other outlet unless you can fully insert the blades to prevent blade exposure.
Using Vehicle Battery Power
You can power the scanner from a vehicle's 12V power source (such as cigarette-lighter socket) using a
9VDC at least 500-mA adaptor with 4.75mm outer/1.7mm inner plug. Its center tip must be set to positive
and its plug must fit the scanner's PWR DC 9V jack. Using an adaptor that does not meet these
specifications could damage the scanner or the adaptor.
WARNING: Always connect the DC adaptor to the scanner before you connect it to the power source.
When you finish, disconnect the adaptor from the power source before you disconnect it from the scanner.
To power the scanner using a DC adaptor, connect the plug into the scanner's PWR DC 9V jack. Plug the
other end of the DC adaptor into your vehicle's cigarette-lighter socket.
NOTE: If you use a cigarette-lighter power cable and your vehicle's engine is running, you might hear
electrical noise from the engine while scanning. This is normal.
Creating Your First New Objects
When the scanner is first turned on after it is unpacked, you are working with a clean slate. You will notice
that your scanner tells you this:
The scanner is in program mode and is ready for you to enter the first Objects into the memory. The
scanner prompts you to Press NEW to create objects.
You will also notice that there are three pushbutton keys beneath the display, and above each button in the
display, a label that indicates the current function of these three keys. These keys are called softkeys, and
they function much like the softkeys on many Automatic Teller Machines. Their meaning can change
depending on the operational state that the radio is in. Right now, the softkeys on your radio should read as
follows:
NEW EDIT GLOB
Let's focus on the NEW softkey for a few minutes. As you might have guessed, NEW is an invitation for you
to create a new Scannable Object (CONV, TGRP, LMIT, SRVC, or SWPR). So, what would you like to
create first? We suggest that you start with a Conventional Channel Object (CONV) first, to get familiar with
the radio's user interface and display.
Conventional Channel Object (CONV)
A Conventional Channel Object (CONV) is a record that stores the parameters for a regular, non-trunked
conventional AM or FM channel. When you create a CONV object, you are creating an object that will allow
you to scan and monitor a “plain old radio channel”, that is, a single frequency and the associated
parameters that are necessary for you to receive traffic on that frequency.
Essential Conventional Channel parameters
CONV objects are the simplest objects supported by the radio. By this we mean that there really isn't that
much for you to do if you want to create one. There are only a few essential parameters in the CONV object
fields that must be set correctly for a CONV object to work. The Frequency must be set to match the
frequency of the transmitter you want to scan or monitor, and the MODE should be set to AU, or, if desired,
AM, FM or NFM. Note that the scanner will automatically select the default mode based on the frequency
you enter when MODE is set for AUto. In most cases it will not be necessary to change this.
We also recommend that you label your CONV object by giving it a name in the TAG field. This will make it
easier for you to find the CONV object later, and identify it when the scanner stops to monitor activity. Enter
your CONV object by following these steps.
As we mentioned above, a brand new radio will launch into Program Mode when it is first turned on, which
allows for creation and editing of Scannable Objects. If this is the first time you have turned on your radio,
you should see these softkey labels at the bottom of your screen:
NEW EDIT GLOB
If not, press the PGM (Program) key now.
Press the NEW softkey to begin entry of a new object.
Press the CONV softkey to begin entry of a CONVentional Channel object. Your scanner's display should
read as follows:
illust
Now, take a moment and study the display. You will notice that the v icon is active. Its purpose is to indicate
that you are at the very top position of the menu for a conventional channel object, and there are more
parameters that can be accessed if you scroll down. We also see three new softkeys:
Save Exit Dflt
The Save softkey will save your new CONV object to the file system when pressed (but don't press it yet!).
The Exit softkey aborts the creation of the new CONV object, and the Dflt softkey restores the selected
CONV menu parameter to its default setting.
If you press the v key on the bottom of the 5-way pushbutton pad, you can scroll down and see all of the
parameters that can be specified for a CONV object. Go ahead and take a peek - then scroll back to the
very top of the display so you can begin entering information for your first CONV object.
HINT: Pressing FUNC ^ or FUNC v will jump to the top or bottom of a menu, respectively.
Note that as you scroll both the upward and downward scroll indicators will illuminate to indicate that there
are parameters above and below the current cursor position, until you get to the very end of the menu,
where only the upward scroll indicator will be on to indicate that there are no more parameters below the
current cursor position. Also note that a few lines of context sensitive help are available for each menu item.
To see the help text for a menu item, press FUNC, then press SEL on the 5-way pushbutton pad. To exit
help, press SEL again.
As you scroll the object menu, you will see a line that states:
vv EXPERT BELOW vv
This line is found in the object menus and the Global configuration menus. Its purpose is to delineate
between the basic settings that are important to each object and the operation of the radio, and the expert
settings that may be of interest to advanced users, but, if left alone, will not adversely impact the operation
of the radio. For more information about the Basic and Expert settings, please refer to the Detailed Menu
Reference at the end of this Owner's Manual.
Use the ^v keys to scroll the screen until the flashing cursor appears next to the Freq: label. Key in a known
local frequency and press the ENT key, or press the DONE softkey - either one will do the same thing.
There! You just entered the frequency for your first CONV object.
By default, your new CONV object will be tagged “Channel”. If you'd like to change this, just scroll the
screen down one click until the flashing cursor highlights the Tag: field, then press SEL to edit the tag. You
can move the cursor around using the <> keys on the 5-way pushbutton pad, use the CL key to clear the
old text, or press FUNC CL to erase the entire field. To enter text, find the letter you want to enter on the
front panel of the radio, press the numeric key beneath it, then press 1, 2, 3, or 4 depending on the position
of the letter in the group for that number. For example, to enter FIRE, press:
3 3 F
4 3 I
7 3 R
3 2 E
Press the ENT key or DONE softkey to store the new tag information for your CONV object.
Now you are ready to store your first CONV object. There are other parameters that you can change, and
we invite you to scroll through the CONV menu to see the other settings that are available. You can
experiment with the different settings. If you make a change that you aren't certain about, press the Dflt
softkey to restore the setting to its original values.
When you're ready, simply press the Save softkey to save your new conventional object. Once the object is
saved, you can continue to enter other new objects, or press MAN to listen to the CONV object you just
entered, or SCAN to start scanning!
NOTE: Your scanner uses Scan Lists as a way to group objects together according to your preferences for
scanning. By default, all new objects are mapped to Scan List 01. There are a total of twenty regular Scan
Lists in your radio, a special Favorites Scan List, and a Scan List to hold Skywarn objects. Scan List
membership for an object is assigned in the individual object menus. For now, just let your new objects go
to the default Scan List 01. Later in this section we will show you how you can group your objects into Scan
Lists.
NOTE: When entering data into a numerical field, you can start typing as soon as you have scrolled to the
desired field, which will replace the contents of the field with your new entry. Alternatively, you can press the
> key, which will preserve the original contents of the field so you can make small changes without retyping
all of the data.
Talkgroup Object (TGRP)
A Trunking Talkgroup Object (TGRP) is a record that stores the parameters for a trunked talkgroup on a
trunked radio system. When you create a TGRP object, you are creating an object that will allow you to
scan and monitor a talkgroup on a particular trunked radio system.
Essential Trunking Talkgroup parameters
As a standalone object, a TRGP object is really no more complicated than a CONV object. The trunking
system (TSYS) that the TGRP is a member of must be specified. Each talkgroup has a digital “address” on
the trunking system, which is called the talkgroup ID, and this must be provided. We also recommend that
you label your TGRP object by giving it a name in the TAG field. This will make it easier for you to find the
TGRP object later, and identify it when the scanner stops to monitor activity.
Setting up and using a Trunking System (TSYS) object
We just mentioned that the TSYS is an essential parameter needed in order for a TGRP object to function
properly and receive radio traffic. The TSYS object has its own set of essential parameters, and these
parameters vary depending on the type of trunked radio system you plan to monitor. If you are a reasonably
experienced user you probably already know what the essential parameters are for the system you wish to
monitor. For example, each TSYS must correctly specify the type of system being monitored, the control
channel or LCN frequencies used by the system, and so on. A detailed description of each type of system
supported by this radio and the essential parameters required to make the different types of trunked radio
systems work properly is provided in the Detailed Menu Reference. So, if all of this makes sense to you
then you should proceed and enter the required data for the system you wish to monitor to make a new
TSYS as you create your TGRP. If not, please refer to the TGRP section of the Detailed Menu Reference
so that you will understand which TSYS parameters are required for the type of trunked radio system you
wish to monitor.
The first time you make a TGRP for a particular trunked radio system, you must also create a TSYS that
contains the system parameters associated with that trunked radio system. Once you create a TSYS object
for the trunked radio system, you can use the TSYS object over and over again without having to re-enter
all of the system data.
Assuming that you have already entered one or more CONV objects (which we recommend you do prior to
attempting the entry of the slightly more complicated TGRP object), you should press the PGM key to place
your scanner into Program Mode, then press the NEW softkey, then press the TGRP softkey. Your radio
display should appear as follows:
illust
In the same way as with the CONV object, this menu of TGRP parameters can be scrolled up and down to
access and enter or change the various parameters associated with a trunking talkgroup.
For the purpose of this example, we will assume that you wish to create a TGRP object for a Motorola Type
II 800 MHz trunked radio system, which is one of the more common types of trunked radio systems in use.
(If this is not the case, we encourage you to refer to the Detailed Menu Reference section of this manual for
more information that applies to the type of TSYS you wish to monitor.)
Scroll the display by pressing the down arrow once so that the flashing cursor is highlighting the TSYS field,
then press the SEL key in the center of the 5-way pushbutton pad. Your radio's display should appear as
follows:
illust
We are entering a new Motorola Type II 800 MHz system, so we can leave the Type: field as-is. It's a good
idea (in fact, a REALLY good idea, for reasons you will see as you proceed) to give your TSYS a unique
name. Press the down arrow key once to scroll to the Tag: field, then press the SEL key and enter a name
for the system using the methods previously described for naming your CONV object. We will use the tag
My System for this particular example in the documentation:
6 1 M
9 3 Y
. <space>
7 4 S
9 3 Y
7 4 S
8 1 T
3 2 E
6 1 M
If necessary, use the decimal/period key or the CL key to delete any unnecessary characters, and press the
SAVE softkey to save your TSYS name. Next, scroll to the Frequencies: field to begin entering the control
channel frequencies for the My System trunked radio system. Press the SEL key, and at the Ch01: field you
should enter the first control channel frequency for your Motorola trunked radio system. Simply key in the
frequency including the decimal point, and press the ENT key or the DONE softkey to store the control
channel frequency. Press the v key and repeat this step to add any other control channels used by the
system. Typically, a Motorola trunked radio site or system will have one active control channel and three
backup control channels. You need only enter the active control channel for the scanner to track the system,
but if the system switches to a backup control channel the scanner will not receive traffic unless the
frequency for the backup control channel has been entered.
Once you have finished entering the control channels, press the SAVE softkey, then press the SAVE
softkey again. This will store the new TSYS into memory and return you to the TGRP parameter entry. Your
display will now appear as follows:
illust
Notice that the system name has changed to reflect the name you chose when you were entering the
parameters for the trunking system. As you enter this TGRP and other TGRP objects for this system, you
will just specify the system name here. So, the TSYS parameters for a system need only be entered once.
You simply specify the already-entered TSYS as needed when building more TGRP objects for the same
system.
Scroll down one click to the ID: field. Note that by default, the trunking talkgroup ID is set to Wildcard.
Wildcard is a special type of TGRP object that allows you to monitor all talkgroup call traffic on the
associated trunked radio system. Wildcard TGRP objects allow you to quickly find and store new or
unknown talkgroups on a trunked radio system. When a Wildcard TGRP object is mapped to an active
Scan List and scanned, all talkgroup traffic on the system is monitored, and you have the option to save or
lock out new talkgroups as they appear. You may wish to save your TGRP object as a Wildcard with no
further changes. If so, just press the SAVE softkey to store your new TGRP as a wildcard. By default it will
take the tag name of ID: Wildcard.
HINT: Wildcard objects are easier to find and change later if you include an abbreviated name for the
system in the tag field.
If you would rather store a TGRP object for a specific talkgroup ID on MySystem, just press the number
keys to enter the talkgroup ID of the desired talkgroup, then press the ENT key or the DONE softkey to
store the ID.
HINT: TGRP objects are also used to receive Private/Individual Calls on trunking systems that support
these call types. Simply change the Type: field from Group to Private. A Wildcard TGRP object with the
Type: field set to Private will monitor all Private/Individual Calls seen on the system, or you can specify a
radio ID to watch for in the ID: field.
You'll want to scroll down two more clicks to the Tag: field and enter an easy to remember name for your
talkgroup that corresponds with its purpose on the trunked radio system. For this example, let's assume
that this is a police dispatch talkgroup, and we would like to use the name “POLICE DISPATCH” for the tag.
Scroll to the Tag: field and press the SEL key on the 5-way pushbutton pad. Using the text entry methods
that you have previously employed for naming your CONV and TSYS objects, name your new talkgroup
“POLICE DISPATCH”:
7 1 P
6 3 O
5 3 L
4 3 I
2 3 C
3 2 E
. <space>
3 1 D
4 3 I
7 4 S
7 1 P
2 1 A
8 1 T
2 3 C
4 2 H
Press ENT or DONE to store the name, then press SAVE to store the TGRP as a new object. As with the
other object types, there are many other parameters you can edit for the TGRP, but for now, that’s all you
have to do to start monitoring traffic on that TGRP! To add more TGRPs on the same system, follow the
same steps above, this time specifying the TSYS that you just created. To create TGRPs on a different
system, follow the steps above, specify a NEW system, and provide the correct parameters for that system,
as shown above.
As a reminder, here are a few important points to remember about monitoring trunked radio systems, and
about TGRP objects in particular:
With regard to trunked radio systems, it is important to note that a "system" cannot be scanned. If one
wishes to monitor radio traffic on a trunked radio system, one must create a TGRP object. A TGRP object
includes the parameters for a trunked radio system so that it will operate properly. Trunking system (TSYS)
parameters are stored as a separate "configuration object", and can be used over and over again in other
talkgroup objects on the same trunked radio system.
Also with regard to trunked radio systems, it is important to note that a talkgroup object may be configured
in one of four different ways to monitor traffic on a trunked radio system. They are as follows:
. Wildcard Talkgroup: will monitor all talkgroup call radio traffic on the desired trunked radio system (press
Dflt in the ID: field of the TGRP object to use Wildcard)
. Talkgroup with TGID: will only monitor talkgroup call radio traffic on the specified TGID (enter the desired
talkgroup in the ID: field of the TGRP object to scan a specified ID)
. Wildcard Private Call: will monitor all private call radio traffic on the desired trunked radio system (press
Dflt in the TGID field to get Wildcard, and set the Type field to Private)
. Private Call with ID: will only monitor private call radio traffic on the specified TGID (enter the desired
Radio ID in the TGID field, and set the Type field to Private)
NOTE: Remember, by default all new objects are mapped to Scan List 01. For now, just let your new
objects go to the default Scan List 01. Later in this section we will show you how you can group your
objects into Scan Lists.
Using DUPE to speed up object entry
DUPE is a powerful feature that will help you when entering multiple objects that have similar
characteristics. DUPE is especially useful when entering multiple TGRP objects that are hosted on the
same trunked radio system, or multiple CONV objects that have similar parameters or tag names. To use
DUPE, press the PGM key, then scroll to the object that you wish to duplicate using the <>^v keys on the
5-way pushbutton pad. Press the EDIT softkey, then press the DUPE softkey. An exact copy of the object
you selected is created, and the scanner displays the newly created object menu so you can change the
parameters that need to be changed prior to saving. Be sure to change the tag name before saving your
new object. When finished, press the SAVE softkey to save the new object.
Try using the DUPE feature now to enter a few more CONV and TGRP objects before continuing. You
might consider using DUPE on your wildcard TGRP object to make a duplicate, then set the Type to Private,
so you'll have a TGRP wildcard for talkgroup calls, and another for private calls.
NOTE: Use caution with DUPE. As soon as you press DUPE, a duplicate of the selected object is created
and saved in memory. Be certain to delete any DUPEd objects that you create accidentally.
Basic Scanning Operation
Now that you have entered a few CONV or TGRP objects you can experiment with Scan and Manual
operation.
Activating Scan Mode will cause your scanner to scan through all Scannable Objects that are members of
enabled Scan Lists and are not locked out. Manual Mode allows you to browse the Scannable Objects you
have created so you can select just one to monitor.
To activate Scan Mode, just press the SCAN key on the keypad. Unless you have explicitly changed Scan
List membership, all of the objects you have entered so far should be mapped to Scan List 01, and your
scanner should begin scanning these objects immediately when you press the SCAN key. The scanner
display indicates Scan Mode as follows:
illust
Study the two rows under the “Scanning” display. Each space represents the status of a Scan List in your
radio. The top row of numbers represents Scan Lists 1 through 10, and the bottom row represents Scan
Lists 11 through 20. Unless you have already enabled other Scan Lists in your radio, you will only see the
number “1” in the top row. All of the other spaces contain “.” symbols, which indicates that these other Scan
Lists are currently not enabled.
If you have included one or more TGRP objects in your programming, and are within range of the trunked
radio system for those TGRPs, you will see the T icon flash periodically while the radio is scanning. The T
icon indicates that the scanner is receiving control channel data from a trunked radio system.
To pause the scanner on an active object so that the scanner does not resume scanning, press the PSE
(Pause) key while the scanner is stopped on that object, and press PSE or SCAN to resume scanning.
Alternatively, you may press MAN to monitor an active object. Although PSE and MAN both stop the
scanner on the active object, there are some small differences in how they operate. PSE pauses the
scanner but keeps the scanner in scan mode, resulting in faster stop/start operation. MAN stops scan
mode completely, and allows you to browse the file system to select other objects to monitor.
While the scanner is Manual Mode, you can browse through the stored objects in your scanner and select
one object to monitor. Use the ^ and v keys on the 5-way pushbutton pad to scroll through the objects
assigned to the current Scan List. The > and < keys on the 5-way pushbutton pad are used to browse up
and down through the Scan Lists, respectively. Only Scan Lists that contain objects are shown when
browsing. A quick low-high wrap beep is played when the scanner reaches the last occupied Scan List and
wraps back to the beginning.
When the scanner is stopped on a TGRP while scanning, or paused in Manual Mode, the display will
appear as follows:
illust
When the scanner is stopped on a conventional channel while scanning, or while paused in Manual Mode,
the display will appear as follows:
illust
Browsing Objects
The 5-way pushbutton pad makes it easy for you to browse the stored objects in your PSR-310 when in
Manual or Program modes. Press MAN or PGM, then use the <>^v keys on the 5-way pushbutton pad to
move around in the scanner's memory as follows:
^: navigates “up” through the objects assigned to the current Scan List
v: navigates “down” through the objects assigned to the current Scan List
<: navigates “up” through the active Scan Lists in the radio
>: navigates “down” through the active Scan Lists in the radio
Advanced Startup Topics
Congratulations! Now that you have mastered the creation of Scannable Objects and how to monitor them
using Scan and Manual Mode, you can move on to some more advanced startup topics.
This Advanced Startup Topics section of this manual will provide you with more basic information about
how you can create other types of Scannable Objects, and how you can group your Scannable Objects into
different Scan Lists and work with the Scan Lists to quickly enable or disable groups of objects that you
want to monitor. You can also read the Detailed Menu Reference section of this manual to learn more about
the different object types and their parameters, and how to perform more advanced operations with your
scanner.
About Object Numbering
Your PSR-310 is different from other types of scanners in how it stores your Scannable Objects in memory.
Instead of fixed channels and banks, objects are stored in the first available block of free memory and
assigned an Object ID. The Object ID is the “address” where the object is stored in memory.
The Object ID is displayed as a four digit number in the upper left-hand corner of the display whenever an
object is selected in Manual Mode and PGM modes, and when the scanner stops on an active object while
scanning. Additionally, the current Scan List number is displayed prior to the Object ID when an object is
selected in Manual Mode or PGM mode, i.e.,
10-0348
indicates Object ID 0348 mapped to Scan List 10.
Using the Object ID to directly access an object
You can use this address to quickly access your stored objects when in the Manual Mode and PGM modes.
Press MAN or PGM, then key the Object ID using the numeric keypad, then press ENT to go to that object.
In the above example, press MAN or PGM, then key 0348 ENT to jump directly to that object.
Note that objects are not really “in” a Scan List, or Scan Lists. Objects are “mapped” to Scan Lists, meaning
that an object can be a member of one or more Scan Lists. In the above example, 10-348 means that the
object itself is stored in memory address 0348, and is mapped to (at a minimum) Scan List 10, and, if you
were to use the ^v keys to scroll up or down while viewing Scan List 10, you will see all the other objects
that are also mapped to Scan List 10.
More About Wildcard Scanning
As mentioned previously, a Wildcard TGRP object allows you to receive all radio traffic on a trunked radio
system.
illust
A Wildcard TGRP works by catching talkgroup calls on the system that are not already stored as objects in
the radio's memory.
In order for the Wildcard TGRP to function properly, the radio needs to be in SCAN mode. This is what
enables the scanner to find the previously stored TGRP objects that need to be checked before declaring
that the found talkgroup is new and should be scanned as a Wildcard “hit”.
If you park on a Wildcard TGRP object in MAN mode, the scanner is not able to “see” the previously stored
TGRP objects, and every call on the trunked radio system will come up as a wildcard hit.
Displaying Memory Usage
Your scanner can report how much free memory is available for new objects, and show how much memory
has been used, and how the memory is allocated to different types of objects. To display the memory usage
report, use the power-on shortcut by pressing 0, then 0 again while the Welcome/Owner screen is
displayed just after the radio is powered on, or, press PGM, then the GLOB softkey to access the Global
configuration menu, then scroll down using the v key until Memory Info:SEL appears in the display. Press
SEL to view the memory usage report. Use the ^v keys to scroll the display.
Search Object Types
A very powerful feature of your PSR-310 is the ability to define different types of frequency searches and
process them while scanning. Frequency searches are just another type of Scannable Object in the
hierarchy of the radio's memory organization, so they can be manipulated and scanned in the same
manner as conventional channels and trunking talkgroups.
There are several different types of frequency searches available in your scanner.
Limit Search Object (LMIT)
A Limit Search Object (LMIT) is a search object that stores the parameters necessary for the radio to
search each frequency within a lower and an upper limit for activity. A LMIT object can be used for
standalone searching - the radio just searches and stops when activity is detected on a frequency, or for
searching that is performed while the radio is scanning. The radio treats LMIT objects just like any other
Scannable Object when in Scan Mode. If you create a LMIT object, assign it to a Scan List and press the
SCAN key, the radio will check for activity on all the Scannable Objects - TGRP objects, CONV objects, and
even LMIT objects. An example of when this might be handy would be when you want to scan for activity
on a collection of TGRP and CONV objects, then run through a range of frequencies to look for activity
there, such as the entire 2 meter amateur radio band or the entire VHF marine radio band. When used in
Scan Mode, this capability is best suited for small ranges of frequencies that contain more frequencies than
practical to program as individual channels. Any size range can be used, but larger ranges that take more
time to search will increase the chances of missed activity on other object types.
Essential Limit Search parameters
Much like the other object types, there are only a few parameters that are essential in order for a search
range to function correctly. The FrLO: and FrHi: lower and upper frequency limits must be specified, so the
scanner will know where to begin the search, and where to end the search and start again. The Mode: must
be set properly, although by default the scanner will automatically choose the receive mode that most likely
applies to the active frequency as the search proceeds. And again, we recommend that you give the LMIT
object a name in the Tag: field so that you can easily find or identify it later.
To create a new LMIT object, press PGM to place your scanner into Program Mode, then press the NEW
softkey, then press the SRCH softkey to view the available Search types, then press the LMIT softkey. Use
the data entry methods you have already learned for CONV and TGRP object setup to specify the FrLO:
and FrHi: limits, and provide a name for your search in the Tag: field. When finished, press the Save softkey
to store your LMIT search as a new object.
Once your LMIT object is saved, you can use it while scanning, or launch the LMIT search by itself by
pressing the SRCH softkey (note that we are referring to the SRCH softkey, and not the SRCH key on the
keypad) after navigating to the LMIT object in Manual Mode.
When the LMIT search stops on an active frequency, the display will appear as follows:
illust
Press the PSE key to hold on the active frequency. To resume, press the PSE key again.
HINT: It can take some time for the PSR-310 to process all of the frequencies in a LMIT search. You can
experiment with different size frequency ranges to find a LMIT search setup that does not interfere
excessively with scanning of other object types.
Spectrum Sweeper Object (SWPR)
A Spectrum Sweeper Object (SWPR) is a record that stores the parameters necessary for the radio to
rapidly sweep a range of frequencies for strong signals from nearby transmitters. A SWPR object can be
used for standalone operation - the radio just sweeps and stops when activity is detected, or for sweeping
that is performed while the radio is scanning. The radio treats SWPR objects just like any other Scannable
Object when in Scan Mode. If you create a SWPR object, assign it to a Scan List and press the SCAN key,
the radio will check for activity on all the enabled Scannable Objects - TGRP objects, CONV objects, LMIT
objects and SWPR objects. An example of when this might be handy would be when you want to scan for
activity on a collection of TGRP and CONV objects, then do a quick sweep for transmissions from nearby
transmitters.
Essential Spectrum Sweeper parameters
Like every other object type, there are certain parameters in a SWPR record that are essential in order for
the SWPR object to function correctly. By default, a newly created SWPR object is ready to go without any
changes. In its default configuration, the SWPR object will sweep through all of the important land mobile
radio bands and look for strong signal activity from nearby transmitters. As you become more familiar with
SWPR operation, you may wish to include or exclude some bands in your sweeps to check other frequency
ranges or to limit the amount of time the scanner spends sweeping frequency ranges where local
transmitter activity is less likely. This will speed up operation, and when used while scanning, will allow the
radio to return to scanning for activity on CONV, TGRP and other enabled objects.
To create a new SWPR object, press PGM to place your scanner into Program Mode, then press the NEW
softkey, then press the SRCH softkey to view the available Search types, then press the SWPR softkey. By
default the SWPR parameters are set for a general purpose sweep of all important land mobile radio bands.
Optionally, you may wish to toggle the Type: field from All Bands to Public Safety by pressing > on the
5-way pushbutton pad. When Public Safety is selected, the frequency sweep will be limited to those
frequency ranges typically used for Public Safety communications. Note that other radio services also use
these ranges, so don't be surprised if you occasionally hear activity that is not Public Safety related. The
sub-bands are defined as follows:
0: 25-54 MHz VHF Low Band
1: 108-136.99166 MHz VHF Aircraft Band
2: 137-174 MHz VHF High Band
3: 216.0025-299.975 MHz 220 MHz Commercial/Amateur Band
4: 300-405.9875 MHz UHF Military Air Band
5: 406-470 MHz UHF Band
6: 470.0125-512 MHz UHF-T Band
7: 764-767 MHz 700 MHz Band
769-776 MHz
794-796.996875 MHz
8: 806-868.9875 MHz* 800 MHz Band
9: 896-960 MHz 900 MHz Band, 23 cm Amateur Band
1240-1300 MHz
* Exzcludes frequencies utilized by the Cellular Mobile Radiotelephone Service 824-848.9875 MHz and
869-893.9875 MHz.
In Public Safety, the sub bands are defined as follows:
0: 33.420-46.5 MHz VHF Low Band
1: 151.820-170.150 MHz VHF High Band
2: 453.0375-467.7125 MHz UHF Band
3: 764.003125-766.996875 MHz 700 MHz Band
769.003125-775.998675 MHz
794.003125-796.996875 MHz
4: 806.0125-868.9875 MHz 800 MHz Band
Sub bands can be selected and deselected by using the <> keys to scroll through the sub bands, and
pressing the SEL key to toggle the selected sub band on or off. An asterisk character (*) indicates that the
sub band is enabled.
Be sure to provide a name for your SWPR object in the Tag: field. When finished, press the Save softkey to
store your SWPR search as a new object.
Once your SWPR object is saved, you can use it while scanning, or launch the Spectrum Sweeper object
by itself by pressing the SWPR softkey after navigating to the SWPR object in Manual Mode.
When the SWPR object stops on an active frequency, the display will appear as follows:
illust
Service Search Object (SRVC)
A Service Search Object (SRVC) is similar to a LMIT search but is optimized for a specific radio service,
and can search for activity associated with a type of service across multiple frequency bands.
Essential Service Search parameters
The only critical parameter needed for a Service Search to function is the service type. When you set up a
Service Search, you will want to specify the type of service that you wish to search.
To create a new SRVC object, press PGM to place your scanner into Program Mode, then press the NEW
softkey, then press the SRCH softkey to view the available Search types, then press the SRVC softkey.
Scroll to the Srvc: field and select the type of search you want to define using the <> keys on the 5-way
pushbutton pad. Service types include Public Safety, Aircraft, Amateur, CB, Marine,

When finished, press the Save softkey to store your SRVC search as a new object.
Once your SRVC object is saved, you can use it while scanning, or launch the SRVC search by itself by
pressing the SRCH softkey after navigating to the SRVC object in Manual Mode.
When the SRVC search stops on an active frequency, the display will appear as follows:
illust
To resume searching, press the ^ key.
Now, take a few moments to practice setting up each of the different search object types by experimenting
and creating some SRVC, LMIT and SWPR objects.
HINT: Remember that there is context sensitive help available for each menu item in the object menus.
Just press FUNC, then SEL to view the help, and SEL again to exit the help screen.
These are just a few of the many ways you can incorporate different types of search objects in your Scan
List configurations. And, just a few of the many ways that each of the individual search types can be
configured to your preferences and needs. Be sure to refer to the Detailed Menu Reference section of the
manual for detailed information for each of the search object types.
Grouping Objects with Scan Lists
By default, new objects are automatically assigned to Scan List 01. Now that you have entered a variety of
new objects that are, by default, members of Scan List 01, you may want to separate these objects into
separate Scan Lists so that you can easily enable or disable groups of objects as needed depending on
what you want to scan. There are 20 regular Scan Lists available, a special “FAV” Scan List for one-button
access to your favorite Scannable Objects, and a Skywarn Scan List.
Although Scan Lists may seem similar to the “banks” that are used in older bank/channel scanner designs,
you will find that they are much more powerful and flexible than “banks”. The number of objects that can be
grouped in a Scan List is limited only by the scanner's memory, and single objects can be members of
multiple Scan Lists without creating duplicate versions of those objects and manually placing them in each
Scan List where you want them included.
You can also mix and match different object types in Scan Lists as you see fit. Feel free to group your
objects in the manner that best suits your listening style. If you choose to group your objects by
geographical area, and find that the best set of Scannable Objects for your area includes a mix of trunked
talkgroups and conventional channels, go right ahead and put them all in the same Scan List. There are no
limitations as to the type of objects that can exist together in the same Scan List.
How you group objects in Scan Lists is entirely up to you! Here are some examples of how objects can be
grouped:
Geographically
You may wish to group your Scannable Objects according to the areas where they are used. For example,
assume that you routinely travel to another town to visit family. You can assign the channels and talkgroups
for fire and police services around your home to one Scan List, and those that are located where your
family lives in another. When you travel to visit your family, you can no longer hear the Scannable Objects
assigned to your home Scan List, so you disable that Scan List and enable the Scan List that contains the
channels and talkgroups that are in use in your family's town.
By trunking system
It is possible to assign any combination of object types to any Scan List. However, you may wish to assign
TGRP objects associated with specific trunked radio systems to specific Scan Lists, so you can easily
enable or disable monitoring of each system by enabling or disabling the associated Scan List.
By object type
It may be desirable to segregate object types by assigning them to specific Scan Lists. For example, you
can assign a group of LMIT or SRVC searches to a single Scan List, and easily activate or deactivate
searching on those objects by enabling or disabling the associated Scan List. You may wish to place your
wildcard TGRP group call or private call objects in a separate Scan List.
By application
You can group objects by their application. For example, you may wish to place all law enforcement related
objects for your area in one Scan List, all fire and rescue objects in another, and all business related objects
in yet another Scan List. Racing fans may wish to group objects for different cars, drivers, teams and tracks
into separate Scan Lists.
By Favorites
The Favorites (FAV) Scan List is a powerful tool that can be used to quickly narrow (or expand) your
scanning profile.
In addition to the normal Scan List map, each Scannable Object menu includes a FAV (yes/no) item. When
FAV is set to YES, the object is a member of the Favorites Scan List in addition to the other Scan Lists that
it is mapped to in the normal Scan List map.
When you press the FAV key, the radio suspends scanning of all objects in the radio except for those that
are set to FAV=YES in their object menus.
You can also add any object to the FAV Scan List by pressing the FUNC key, then FAV while the object is
active during SCAN mode, or while parked on the object in MAN and PROGRAM mode.
It is also possible to clear the FAV Scan List completely by pressing PGM, then the GLOB softkey, then
scrolling to down to the Clear FAV menu item. Press the SEL key to set FAV=NO for all objects, press the
YES softkey to confirm the action, then press the Save softkey to save your changes.
For example, you may wish to leave the FAV Scan List empty, and add your favorites while scanning by
pressing FUNC, then FAV when objects of interest are active. This can be useful during a major event,
where you wish to quickly isolate objects of interest by pressing FUNC FAV when they are active, then
pressing FAV to scan only those objects.
The Favorites Scan List is also useful to group objects that are very close to where you live, so that when
you press the FAV key, you are only scanning objects that are in your immediate vicinity, making the radio
less active and increasing the chances that you will not miss important local activity.
Use your imagination and you will probably come up with many other ways to use the Favorites Scan List
feature.
Mapping Objects to Scan Lists
By default, every new object you create is mapped to be a member of Scan List 01. Scan List membership
is defined in an object’s parameters menu and is typically found at the beginning of the menu.
To change Scan List membership when creating a new object, scroll up or down to the Scan Lists:
parameter in the object's menu before saving the object. With the Scan Lists: field highlighted (as indicated
by the blinking cursor), use the <> keys on the 5-way pushbutton pad to scroll through the Scan Lists until
you find the Scan List that you wish to enable or disable membership for the object, and use the SEL button
to toggle membership for that Scan List on or off. The asterisk (*) next to the Scan List number indicates
that the object is a member of that Scan List. Press the Save softkey to save the modified object. Objects
can be members of as many Scan Lists as you see fit, without limitation to the number of Scan Lists an
object is mapped to, and without limitation to the number of objects that are mapped to a given Scan List.
To change Scan List membership for an existing object, press the PGM key. Use the <>^v keys on the
5-way pushbutton pad to scroll to the existing object that you wish to change, then press the EDIT softkey.
Press the CURR softkey to edit the current object.
NOTE: Remember, when browsing objects in Manual or Program Mode, the arrow keys on the 5-way
pushbutton pad operate as follows:
^: navigates “up” through the objects assigned to the current Scan List
v: navigates “down” through the objects assigned to the current Scan List
<: navigates “up” through the active Scan Lists in the radio
>: navigates “down” through the active Scan Lists in the radio
Scroll down in the object's parameters menu to the Scan Lists: field. With the Scan Lists: field highlighted,
use the > on the 5-way pushbutton pad to scroll through the Scan Lists, and use the SEL button to toggle
membership for a Scan List on or off. The asterisk (*) next to the Scan List number indicates that the object
is a member of that Scan List. Press the Save softkey to save the modified object.
Naming, enabling and disabling Scan Lists
By default, Scan Lists are named “Scan List 01 - Scan List 20”. If desired, you can give your Scan Lists
names to describe their function. Press PGM, then press the GLOB softkey and scroll down to the Scan
Lists parameter. Press the SEL key to display the Scan Lists sub menu. Scroll to the desired Scan List and
press the > key to edit the settings for the selected Scan List, Scroll to the Tag field and press the > key to
edit the name. Press the Done softkey when finished, then press the Save softkey to save the changes to
the Scan List sub menu, then press the Save softkey again to save the changes to the Global menu. Scan
Lists may be enabled or disabled while actively scanning, or by accessing the individual Scan List in the
Global Settings (GLOB) menu.
To toggle a Scan List's enabled/disabled status while scanning, press the numeric key that corresponds
with the Scan List you wish to toggle. For example, pressing 4 while scanning will toggle the state of Scan
List 04 from enabled to disabled, or vice versa if the Scan List is already disabled. To toggle the
enabled/disabled status for Scan Lists 11-20, press FUNC, then press a number key, i.e., press FUNC 3 to
toggle the status of Scan List 13. If you enable a Scan List that has no assigned objects, the number for
that Scan List will flash in the display while the scanner is scanning.
When you enable a Scan List, the display briefly shows the name of the Scan List on Line 4 of the display,
and the word ON or OFF at the end of Line 3 to indicate if the Scan List was toggled on (enabled) or off
(disabled).
When Scan Lists 1, 2, 3 and 16 are enabled, the display will appear as follows while scanning:
illust
To toggle a Scan List's status from the Global Settings menu, press PGM to enter Program Mode, then
press the GLOB softkey. At the Scan Lists: item, press the SEL key on the 5-way pushbutton pad. Scroll to
the Scan List you wish to change and press the SEL key again, then at the Enabled: setting press the < or
> on the 5-way pushbutton pad to toggle the Scan List on or off. An asterisk (*) indicates that the Scan List
is enabled. Press the SAVE softkey to save settings for that Scan List, then press SAVE again to confirm
your global changes and exit the GLOB menu.
If you inadvertently store an object with no Scan List mappings, the object will be placed in a special “NS”
Scan List that can be accessed using the <>keys while in Manual Mode or PGM mode. Once you scroll to
the NS Scan List, you can use the ^v keys to scroll to the objects found there and edit the Scan List setting
by pressing the PGM key, then the EDIT and CURR softkeys to see the object's menu.
Other Advanced Startup Topics
Here are some more startup topics that will help you get more enjoyment out of your PSR-310 as you
become more experienced with its operation. We also suggest that you visit RadioReference at
www.radioreference.com, where you can discuss the PSR-310 with other owners!
Finding Stored Objects Easily
The PSR-310's browse feature makes it easy to scroll to the Scan Lists and Scannable Objects you have
created, using the <>^v keys on the 5-way pushbutton pad while the scanner is in PGM or Manual Mode.
Here are some more methods you can use to find stored objects quickly.
Searching For Objects Using FIND
Your PSR-310 provides a very useful FIND feature that allows you to search for locked out objects, or for
objects that contain a text string that you specify. In text searches, FIND searches for your specified text in
the following places:
. In TGRP objects, the ID field and the Tag field
. In CONV objects, the Frequency field and the Tag field
. In TSYS, LMIT, SRVC and SWPR objects, the Tag field
To use FIND, press the PGM key, then press the EDIT softkey. Press the FIND softkey.
To find objects that are locked out, press the L/Out softkey. The scanner finds the first locked out object.
Press the L/OUT key to toggle lockout status. Press the EXIT softkey when finished. Press the EDIT
softkey to edit the object menu for the found object. Press the NEXT softkey to find the next locked out
object. When the scanner finds a matching object, you may press MAN to begin monitoring of the found
object in Manual mode. You may also press PGM to exit FIND and execute programming tasks at the found
object position. If you wish to edit the object, press the EDIT softkey. If you wish to continue searching,
press the NEXT softkey.
To find objects that contain a specified text string, press the Text softkey then enter the text string you wish
to search for. Press the OK softkey to begin searching. Press the Exit softkey to cancel the FIND operation.
Press the Qtxt softkey to use QuickText in your find text screen. For more information on text entry and
QuickText, please see the section of this manual entitled “Standard Text Entry Method and QuickText”.
Once you have started searching, the radio will stop on any object where your find text is found in the
frequency, tag, or ID fields as described above. When the scanner finds a matching object, you may press
MAN to begin monitoring of the found object in Manual mode. You may also press PGM to exit FIND and
execute programming tasks at the found object position. If you wish to edit the object, press the EDIT
softkey. If you wish to continue searching, press the NEXT softkey.
FIND keeps the last search text you specified stored so that you may use it again in subsequent FIND
operations.
Filtering By Object Type
When browsing objects in PGM mode, you can filter the objects that are displayed by their type.
Press the PGM key on the keypad, then press the EDIT softkey. Press the < or > keys on the 5-way
pushbutton pad to scroll the Edit softkeys to display the filter softkeys. The filter softkeys are as follows:
CONV
TGRP
TSYS
SRCH
SWPR
To filter browse for a specific type of object, press the softkey that corresponds with that object type. For
example, press the CONV softkey, then use the <>^v keys on the 5-way pushbutton pad to browse only
conventional objects.
Object Lockout
The L/OUT key is used to lock out objects. When an object is locked out, traffic is not received on that
object until it is unlocked, even if the object is mapped to more than one Scan List. Locking out an object
locks it out “radio-wide” until it is enabled by toggling the lockout setting.
Four types of lockout functions are available in the PSR-310, temporary lockout, permanent lockout, search
lockout and talkgroup lockout.
Temporary Lockout
Temporary lockout locks out an object until the scanner is turned off. When the scanner is powered on
again, all objects that have been temporarily locked out are restored.
By default, the L/OUT key activates temporary lockout when pressed. If desired, you can change the
function of the L/OUT key in the GLOB radio wide settings by pressing PGM, then the GLOB softkey. Scroll
to the TLO=FUNC L/O setting and press the > key to toggle the setting to YES to have the L/OUT key
function as a permanent lockout instead of temporary lockout.
To apply temporary lockout to an object, press the L/OUT key while the scanner is stopped on that object
during scan operation, or navigate to an object using the 5-way pushbutton pad while in Manual Mode or
PGM mode and press the L/OUT key. The lowercase “l” in the display flashes to indicate that temporary
lockout is applied to the object:
illust
If you wish to remove temporary lockout from a single object, navigate to the object using the 5-way
pushbutton pad while in Manual Mode or PGM mode and press the L/OUT key again.
Temporary lockout is a very useful feature. For example, when a major incident occurs while you are
scanning, you may wish to focus your scanning on that major incident, and exclude unrelated talkgroups so
that radio traffic associated with the major incident is not interrupted.
You could press the PSE or MAN keys to listen to a single object, if communications for the major incident
are only being conducted on single channel or talkgroup. More often, several talkgroups are used to
provide communications for major incidents, so if you park on a single object, you may miss
communications on other objects that are related to the incident of interest.
By using Temporary Lockout, it is possible to “zoom in” on the objects that are carrying communications
related to the incident of interest by pressing L/OUT every time an unrelated object becomes active.
Eventually you will narrow down your monitoring to those objects that are being used to provide
communications for the incident you are trying to monitor.
Permanent Lockout
Permanent lockout locks out an object until you explicitly unlock it. No traffic will be received on the locked
out object while permanent lockout is active.
To apply permanent lockout to an object, press FUNC, then the L/OUT key while the scanner is stopped on
that object during scan operation, or navigate to an object using the 5-way pushbutton pad while in Manual
Mode or PGM mode and press FUNC, then the L/OUT key. The lowercase “l” in the display changes to
uppercase to indicate that permanent lockout is applied to the object:
illust
If you wish to remove permanent lockout from an object, navigate to the object using the 5-way pushbutton
pad while in Manual Mode or PGM mode and press FUNC, then L/OUT again.
HINT: You can also toggle lockout anytime you are viewing an object menu in Program mode by pressing
L/OUT.
Search Lockout
Search lockout works with certain search objects, including LMIT searches, some SRVC searches, and
SWPR objects. Frequency lockout is used to lock out undesired frequencies that are found during
searches.
To apply search lockout during a search, press the FrL/O softkey while the scanner is stopped on the
undesired frequency:
illust
Applying search lockout to an undesired frequency adds that frequency to the Search Lockout List, a list of
frequencies that the scanner ignores when performing searches or during Spectrum Sweeper operations.
You can edit or clear the Search Lockout List by following these steps:
Press PGM
Press the GLOB softkey
Scroll down to the SRCH L/Outs: item and press SEL
Scroll to the frequencies you wish to remove from the lockout list and press the Del softkey to remove them
from the list.
Scroll to an empty spot and enter any frequency you wish to manually add to the list.
Press FUNC, then the Del softkey to clear the entire list.
Talkgroup Lockout
Talkgroup lockout is similar to search lockout, as it allows you to lockout undesired talkgroups while
searching for new talkgroup activity with wildcard TGRP objects.
To apply lockout on an undesired wildcard hit, press the TGL/O softkey while the scanner is stopped on the
undesired talkgroup:
illust
Applying wildcard lockout to an undesired talkgroup creates a new TGRP object in the same Scan List as
the wildcard TGRP, then applies permanent lockout to the new TGRP object, so that will be ignored in the
future by the scanner when scanning the wildcard talkgroup. To unlock or edit talkgroups locked out using
the wildcard lockout feature, press PGM, then navigate to the object using the 5-way pushbutton pad.
Press FUNC, then L/OUT to remove permanent lockout from the talkgroup. Press FUNC, then CL to delete
the TGRP object from the scanner. Press the EDIT, then the CURR softkey to edit and save the TGRP
object.
Setting the Default Scan List
By default, your scanner will store all new objects, and objects found during Search, Tune, and Sweeper as
mapped to Scan List 01.
You can easily change the default Scan List to any Scan List you specify, including the special FAV and
SKYWARN Scan Lists.
Press PGM, then the GLOB softkey, and use the v key to scroll down until the Dflt ScanList item appears in
the middle of the display. Enter a new Scan List number to use as the default Scan List. The following
numbers are valid:
0: The “not scanned” (ns) Scan List - objects that have no Scan List mappings can be found here
1-20: The twenty normal Scan Lists
21: The FAV Scan List
22: The SKYWARN Scan List.
Press ENT or the Done softkey to store your new default Scan List value, then press the SAVE softkey to
save your changes to the radio's configuration memory.
Deleting Objects
Objects that you no longer need to use can easily be deleted from the PSR-310's memory, making room for
new objects.
To delete an object, press PGM, then use the <>^v keys to navigate to the object you wish to delete. Press
FUNC CL to delete the object. The scanner will ask you to confirm the delete command before removing
the object from the scanner's memory. Deletions cannot be un-done.
To delete a TSYS, use the FIND feature to search for the TSYS by name. Press PGM, then press the EDIT
softkey, then press the FIND softkey, and use the Standard Text Entry Method to enter all or part of the
TSYS name you wish to delete. Press the OK softkey to begin searching, and, if necessary, press the
NEXT softkey to continue searching until the desired TSYS is located. Once the TSYS has been located,
press the PGM key, then press FUNC CL. The scanner will ask you to confirm the delete command before
removing the object from the scanner’s memory, then, provide a final warning that all TGRPs associated
with the TSYS to be deleted will be lost if you proceed. Press the YES softkey at both warnings to delete
the TSYS.
An alternative method is to browse TSYS objects only using the TSYS filter. Press PGM, then the EDIT
softkey, then >>>, and press the TSYS softkey. Scroll to the desired TSYS using the ^v keys, then press
FUNC CL. The scanner will ask you to confirm the delete command before removing the object from the
scanner's memory, then, provide a final warning that all TGRPs associated with the TSYS to be deleted will
be lost if you proceed. Press the YES softkey at both warnings to delete the TSYS.
Using Multi-Site Mode On Networked Systems
Some Motorola systems include a large number of sites that are networked together to provide radio
coverage to a large geographical area. These types of trunked radio systems are more commonly used for
large statewide systems, and for some systems that are used in large, rural counties.
These networked trunked radio systems work in a manner that is very similar to a cellular telephone
network. As a system user moves around (or “roams”) in the coverage area of the network, their radio will
automatically find and use the nearest tower site. Each tower site includes a number of channels. One of
these channels is used for control channel data, and the remaining channels are used for voice traffic. As a
user moves away from the coverage of one site, their radio will search other control channel frequencies for
a better site to use.
Your PSR-310 includes a Multi-site feature that can enhance the operation of the scanner when monitoring
Multi-site systems. Multi-site can be enabled by editing the trunking system (TSYS) parameters for a
Motorola system. Multi-site can be set to Off, Stat (Stationary) or Roam. By default, Multi-site is set to OFF.
The ROAM setting is ideal for those times when you are driving around in the service area of a networked
trunked radio system, as it allows the radio to find and use the best tower sites as you move in and out of
the coverage footprints of different sites. The STAT(ionary) setting is ideal for those times when you are not
moving and are within range of more than one tower site, as it will allow you to monitor traffic from any
tower that you are within range of.
To activate Multi-site mode on a Motorola networked system, follow these steps:
Press PGM, then navigate to a talkgroup on the networked multi-site system using the <>^v keys.
Press the EDIT softkey, then press the CURR softkey.
Scroll down to the TSYS item and press the SEL key to edit the TSYS parameters.
Scroll to Multi-Site. Use the <> keys to select Off, Stat or Roam. When set to Off, the scanner will find the
first usable control channel in the control channel list and use it until it is no longer usable. When set to
Stat(ionary), the scanner will track the system using any control channel in the list that is usable. When set
to Roam, the scanner will attempt to locate and use the best possible control channel and ignore others,
until the control channel is no longer usable, then it will locate a new “best control channel” to use. When
Multi-Site=ROAM, the scanner will always attempt to lock on to control channels where the decoding
quality is greater than the Threshold Hi setting, and will search for new control channels when the decoding
quality of a control channel drops below Threshold Lo setting, and, if no new control channels are available
that meet the Threshold Hi criteria, the scanner will seek the best control channel to use, and continue
checking periodically for a new control channel that meets the Threshold Hi criteria. When Multi-Site=STAT,
the scanner will track the system using every usable control channel in the control channel list.
Press the SAVE softkey to save your changes to the TSYS parameters, then press the SAVE softkey again
to use the scanner.
You should experiment with the different Multi-site modes and the threshold settings to find a combination
that works best for your location. Keep in mind that the threshold settings are only available when Multi-Site
Roam is selected.
Multi-site functionality is not available in EDACS or LTR trunking.
NOTE: It may be necessary to change the values used for Threshold Hi and Threshold Low in the TSYS
object to optimize Multi-site Roam performance.
LTR Home Repeater AutoMove
LTR Home Repeater AutoMove takes the guesswork out of programming LTR trunking systems when the
home repeater order is not known.
By default, LTR Home Repeater AutoMove is turned off and is controlled in the individual TSYS objects. To
enable LTR Home Repeater Automove, access the menu for the desired TSYS, then scroll down to the last
item in the menu, AutoMove HRs. Use the <> keys to toggle AutoMove HRs on or off for the selected TSYS,
then press the Save softkey to save your changes.
When AutoMove HRs is turned on, you may enter the LTR system frequencies in any order, and the
PSR-310 will automatically move the frequencies to the proper home repeater slots as transmissions are
received on the system.
Priority Scan
Your PSR-310 scanner features Priority Scan operation for CONV and TGRP objects. When Priority Scan
is active, increased priority is given to objects that have their Priority mode set to ON.
Turning Object Priority On or Off
Priority for CONV and TGRP objects can be toggled on or off using the following methods:
Press the PRI key when the scanner stops on the object while it is active. The plD indicator in the object
display will show p for Object Priority Off, and P for Object Priority On.
Browse to an object in Manual Mode or PGM mode, then press the PRI key to toggle Object Priority on or
off. The plD indicator in the object display will show p for Object Priority Off, and P for Object Priority On.
Browse to an object in PGM mode. Press the EDIT, then CURR softkeys. Use the v key to scroll to the
Priority setting. Use the < or > keys to toggle Priority On or Off.
When creating a new object, before saving the object scroll to the Priority setting. Use the < or > keys to
toggle Priority On or Off.
Turning Priority Scan Mode On or Off
While the radio is scanning, press FUNC, then PRI to toggle Priority Scan On or Off. Priority Scan status is
shown in the man Scanning status display. PRI indicates that Priority Scan mode is on, and pri indicates
that Priority Scan mode is off.
CONV Priority Scan
When Object Priority is set to Yes for one or more CONV objects, the scanner will sample the CONV
objects for activity periodically while scanning and monitoring other objects.
This sampling will cause a brief muting of received audio when it occurs while another object is active.
The more CONV objects are set for Priority, the longer this audio muting will be, since it takes a certain
amount of time to sample each Priority CONV object for activity.
TGRP Priority Scan
When Object Priority is set to Yes for one or more TGRP objects, the scanner will give those TGRPs priority
over other TGRPs while checking a particular trunking system for activity. TGRPs configured for Priority are
checked for activity before any other TGRPs are checked, and during the reply delay time after non-priority
TGRP calls.
Additionally, your PSR-310 decodes the subaudible priority data that is present on analog Motorola
talkgroup calls (3600 baud control channel systems only), and will switch to a priority talkgroup when the
data for that talkgroup is found in the subaudible priority data.
Hit Counters
Your PSR-310 includes a unique Hit Counter feature that keeps track of how many transmissions are
received for each object type. The Hit Counter for an object is incremented each time a transmission is
received on an object, making it possible for you to determine the objects that are the least and most active.
By default, the Hit Counter feature is turned off. To turn the Hit Counter on, press PGM, then the GLOB
softkey, and use the v key to scroll down to the Hit Counts item. Use the <> keys to toggle Hit Counts on
and off. When finished, press the SAVE softkey to save your changes to the radio's configuration memory.
You can view the hit counts for an object by navigating to the object by pressing PGM, then using the <>^v
keys to navigate to the desired object, if necessary. Once you have selected the desired object, press the
EDIT softkey, then the CURR softkey, and scroll to the Hit Count item bottom of the object menu to view the
hit counter.
To reset the hit counter for a single object, press the Dflt softkey while the Hit Count item is selected in the
object's menu.
To clear all hit counters, press the PGM key, then the GLOB softkey. Use the v key to scroll down to the
Clear Hits item, then press the SEL key. Press the SAVE softkey to save your changes and exit the Global
settings menu.
Audible Alarms and the ALERT LED
Your PSR-310 features a very powerful ALERT LED with Audible Alarm capability that allows you to set
different types of visual and audible notifications for the different types of objects you create.
You may have noticed that the menus for each object you create include various settings for LED, Backlight
and Alarm. You can use these settings to design custom visual and/or audible alarms that are triggered
when activity is detected on the specified Scannable Object.
NOTE: The Alert LED utilizes a special tri-color Light Emitting Diode module that mixes light from red,
green and blue LED elements to produce thousands of different colors. Eight pre-defined color settings are
available for use in object menus. LED COLOR: 0 is normally used for “all colors off”, or no Alert LED
display.
NOTE: Slight variations to LED colors are a normal part of the manufacturing process. You may notice
these variations when using the White LED color setting (LED COLOR: 0), or when comparing one
PSR-310 to another. You can compensate for these slight variations by fine-tuning the Red/Green/Blue
(RGB) LED settings for each color. See the COLOR settings in the GLOB menu in Detailed Menu
Reference section at the end of this manual.
Audible Alarm and ALERT LED Settings
Each object you create has the following ALERT LED and Audible Alarm settings:
LED Mode: Solid or Flash controls whether the LED remains on solid or flashes when the object is active.
LED Color: 0-7 sets the color of the LED. By default, color 0 is used for LED off. You can change the LED
colors in the Global Settings menu.
Latch LED keeps the LED on after activity on the object is finished. This is useful in cases where you need
to know if an object was active while you were away from the scanner.
Backlight: Off, On, Flash controls whether the backlight remains off, comes on solid or flashes when the
object is active.
Alarm: None, Chirp, Hi-Lo, Alert, Ring, 2-Chirp, Fast Hi-Lo, DTMF # are used to set audible alarms that
play each time activity is found on the object.
ALERT LED with Audible Alarm Examples
Here are some examples of when you may wish to use the ALERT LED with Audible Alarm capability:
. You have programmed a Talkgroup Wildcard in for a trunked radio system you monitor in order to find new
talkgroups. You can use an Audible Alarm to alert you when the radio receives a wildcard hit, and turn on
the backlight so that you can read the display and operate the keypad to save or lock out the new
talkgroup.
. You have programmed your favorite amateur radio repeater in and wish to be alerted when a QSO begins.
You can use an Audible Alarm with one of the shorter alarms (Chirp, 2-Chirp, Fast Hi-Lo or DTMF #) to
provide this indication without covering the traffic in the QSO.
. You have included a Spectrum Sweeper object in your scan configuration so that you can find nearby
strong transmitters while you are scanning. You can use an Audible Alarm to alert you when the radio
receives a Spectrum Sweeper hit, and turn on the backlight so that you can read the display and operate
the keypad to save or lock out the new frequency. This technique is also useful for TGRP wildcards.
. You wish to assign different LED colors to different types of public safety agencies, i.e., red for fire, rescue
and EMS, blue for law enforcement, yellow for emergency management, and so on. When there is activity
you can tell if it is related to law enforcement, fire/rescue and EMS or emergency management at a glance,
even if the transmission is short or difficult to copy.
The possibilities for the ALERT LED with Audible Alarm capability are limited only by your imagination.
Dedicated search modes
In addition to its powerful ability to store different types of frequency searches as objects, your scanner
provides fast access to dedicated frequency search modes that allow you to execute searches or run the
Spectrum Sweeper without having to go through the process of setting up and saving a search object. This
is handy for those times where you need to run a search quickly. Dedicated search modes do not create
new search objects or use previously created search objects.
Using Dedicated Spectrum Sweeper (SWPR) Mode
Dedicated SWPR mode lets you access and run the Spectrum Sweeper easily and quickly. Press FUNC
SCAN while in the Manual, Program or Scan Modes to access the Spectrum Sweeper dedicated mode.
illust
NOTE: When a signal is being received, the Band softkey (F1) changes to FrL/O. You can access the Band
softkey by pressing FUNC F1 when the F1 key function is FrL/O.
Operation of the dedicated Spectrum Sweeper mode is almost identical to that of the object mode, with one
exception. When running the Spectrum Sweeper as a Scannable Object, you must use the object menu to
enable or disable the Spectrum Sweeper sub-bands when operating in Scan Mode. When dedicated
Spectrum Sweeper mode is used, you may press the numeric key on the keypad that corresponds with the
sub-band you wish to enable or disable. Disabling a sub-band will cause the Spectrum Sweeper system to
skip the frequencies within that sub-band as it performs its sweeps. The sub-bands are defined as follows:
0: 25-54 MHz VHF Low Band
1: 108-136.99166 MHz VHF Aircraft Band
2: 137-174 MHz VHF High Band
3: 216.0025-299.975 MHz 220 MHz Commercial/Amateur Band
4: 300-405.9875 MHz UHF Military Air Band
5: 406-470 MHz UHF Band
6: 470.0125-512 MHz UHF-T Band

Using dedicated TUNE mode
Your scanner's dedicated TUNE mode provides you with the ability to quickly enter any frequency and
monitor that frequency for transmissions, or search up or down from that frequency for activity.
To enter TUNE mode, press the TUNE key on the keypad. The scanner displays the TUNE screen.
illust
By default, TUNE mode is paused when first activated. Press PSE to begin searching from the current
frequency.
Press the ^ or v keys on the 5-way pushbutton pad to change the search direction.
Press the FrL/O softkey to add a found frequency to the lockout list.
Press the MODE softkey to change the receive mode (AM, FM, NFM) from the default for the current
frequency range (au).
Press STOR to create a new CONV object using the found frequency.
Use the keypad to enter a new frequency, and press ENT to make that the TUNE frequency.
Using FUNC TUNE from any other mode will load the last active frequency from the other mode into TUNE.
For example, pressing FUNC TUNE while parked on a trunked radio TGRP will load the control channel
frequency into the TUNE mode if the control channel frequency is the last frequency that the scanner
checked while scanning.
Dedicated TUNE mode will always check for the presence of encoded squelch modulation each time it
finds an active frequency. If a valid encoded squelch code is found, it will be shown on the display, and
stored automatically when you press STOR to create a new CONV object.
Dedicated TUNE mode also displays information about trunking control channels and trunked voice
channels it finds while tuning through the RF spectrum. The following information is displayed for the
various trunking modes:

should be expected.
You may wish to use the PSR-310's Tune LED feature to obtain a visual indication of signal strength using
the tri-color LED. To activate the Tune LED, press PGM, then the GLOB softkey. Press the v key until Tune
LED: Off appears in the display. Use the <> keys to toggle Tune LED on or off, then press the SAVE
softkey to save your changes to the radio's configuration memory.
Using dedicated Limit and Service search modes
The SRCH key provides immediate access to the dedicated search modes of your PSR-310. Pressing the
SRCH key cycles through each search mode in this order: Limit, Railroad, Public Safety, Aircraft, Ham, CB,
Marine, and FRS/GMRS/MURS/DOT.
LMIT Search Mode
Your scanner's dedicated LMIT search mode provides you with the ability to create a limit search with a
search frequency range between upper and lower limit frequencies that you specify and perform the limit
search directly without creating a new LMIT object. You can then monitor that frequency range for
transmissions.
To enter LMIT mode, press the SRCH key on the keypad repeatedly until the display indicates LMIT search
as follows:
illust
Use the Lmts softkey to set the lower and upper frequency limits for your limit search.
NOTE: When a signal is being received, the Lmts softkey (F1) changes to FrL/O. You can access the Lmts
softkey by pressing FUNC F1 when the F1 key function is FrL/O.
Press the ^ or v keys on the 5-way pushbutton pad to change the search direction.
Press the MODE softkey to change the receive mode (AM, FM, NFM) from the default for the current
frequency range (au).
Press the FrL/O softkey to add a found frequency to the lockout list.
Press the STOR softkey to create a new CONV object using the found frequency.
Using dedicated SRVC mode
Your scanner's dedicated SRVC search modes provide you with the ability to instantly access each of the
scanner's service search ranges without creating a new SRVC object.
To activate dedicated SRVC search mode, press the SRCH key on the keypad repeatedly until the desired
service search is indicated on the display. The following service searches are available:
Railroad - searches the Association of American Railroads (AAR) VHF railroad frequencies used in the US

Press the ^ or v keys on the 5-way pushbutton pad to change the search direction.
Press the FrL/O softkey to add a found frequency to the lockout list.
Press the STOR softkey to create a new CONV object using the found frequency.
Using Weather Modes
Your PSR-310 also functions as a powerful weather alert receiver. There are three modes of weather alert
operation available to you.
NOTE: Your scanner incorporates weather alert as one of its features and is an extremely sensitive high
quality receiver on the weather frequencies. However, the included flex antenna is optimized for general
purpose scanning. If you use this scanner as your only means for receiving weather alerts, please check to
be sure you are receiving a clear signal on the flex antenna or switch to an external antenna that gives you
clear reception of a local NOAA weather broadcast.
Weather Radio Mode
Weather radio mode allows you to receive weather broadcasts from your local weather service anytime of
the day.
To use weather radio mode, simply press the WX button on the keypad. The scanner will quickly scan and
lock on to the first active weather radio frequency it receives. You can use the ^ or v keys on the 5-way
pushbutton pad to force the radio to look for other weather radio transmitters. It is generally best to select
the weather radio transmitter that provides you with the strongest signal. You can use the signal meter to
help you chose the best weather radio transmitter for your area. While operating in Weather Radio Mode,
your scanner will alert on SAME messages that match the SAME location codes you have entered, or all
SAME messages if you do not enter any SAME location codes.
illust
Weather Priority Mode
Weather Priority mode samples the specified weather frequency periodically while scanning to see if the All
Hazards 1050 Hz Warning Alert Tone (WAT) is present. If the WAT is present, the scanner will sound an
alarm and tune to the specified weather frequency to monitor the nature of the alert.
To activate Weather Priority Mode, follow the steps above listed above in Weather Radio Mode to find the
strongest weather radio transmitter for your area. Once the radio is tuned to the strongest weather radio
transmitter for your location, press the PRI key on the keypad. When in Scan Mode, the radio will check the
specified weather frequency periodically for the 1050 Hz Warning Alert Tone (WAT). If WAT is found, the
radio will sound an alarm and monitor the weather alert audio.
SAME Standby Mode
SAME Standby Mode monitors the specified weather frequency silently, waiting to receive a Specific Area
Message Encoding (SAME) alert that corresponds with a SAME location code that you have previously
entered. If there is a match between a sent SAME location code and one that you have previously stored,
the scanner will sound an alarm, display the alert type, and monitor the nature of the alert.
To activate SAME Standby Mode, first you should provide at least one SAME location code for your city,
county or state. By default, SAME mode will alert on any SAME message received if no SAME location
codes are entered. A list of SAME location codes can be found online at this web site:
http://www.nws.noaa.gov/nwr/indexnw.htm#sametable
In addition to the code for your location, you may wish to enter additional codes for surrounding areas and
any other areas of interest so that you can receive advance warning of adverse or dangerous weather that
may be headed in your direction.
Unlike other weather alert radios, your scanner features a powerful SAME wildcard feature that allows you
to set the radio to alarm on partial matches of the location code. For example, the SAME location code for
Dallas, TX is 048113, which can be broken down as follows:
0 represents a subdivision within a county, and is typically not used.
48 is the State code for Texas
113 is the County code for Dallas County
Entering the entire 048113 code will cause the radio to receive all SAME alerts that match the code for
Dallas County.
Suppose you wanted to receive any alert for any county in the entire state (provided that the alert is sent by
your local NWS transmitter). Using the wildcard feature you can enter a SAME area code as follows:
*48***
This tells the radio to alert on any SAME message with a location code that matches 48 for the state of
Texas.
Your scanner also allows you to specify the event code. The default alert code is “***”, which is best for
most general purpose weather alert monitoring purposes. A list of event codes can be found at this web
site:
http://www.weather.gov/os/eas_codes.shtml
Each SAME location/event code storage location can be configured for Entry ON/OFF and Lockout
ON/OFF.
When a SAME location/event code storage location is set for Entry ON, the radio will process the SAME
location/event code that is stored there. When a SAME location/event code storage location is set for Entry
OFF, that SAME location and event code will be ignored.
When a SAME location/event code storage location is set for Entry ON and Lockout ON, the radio will
process the SAME location/event code that is stored there, and will lock out the specified event code. A
SAME location/event code storage location set for Entry: OFF and Lockout: ON will not be processed,
because Entry is set to OFF. In case of a conflict (i.e., two identical codes and events are entered, and one
is locked out), the locked out entry will take precedence.
SAME Entry Examples
Using the Dallas County, TX example above:
SAME Entry 1:
Code: 048113
Event: ***
Entry: ON
Lockout: OFF
SAME Entries 2-10:
Code: ******
Event: ***
Entry: OFF
Lockout: OFF
The above entry for 048113 will receive all SAME messages for 048113.
SAME Entry 1:
Code: 048113
Event: ***
Entry: ON
Lockout: OFF
SAME Entry 2:
Code: 048113
Event: RWT
Entry: ON
Lockout: ON
The above combination of entries for 048113 will receive all SAME messages for 048113, except the
Required Weekly Test (RWT) message, since the second entry is ON, with lockout ON, and with RWT in
the event field.
SAME Entry 1:
Code: 048113
Event: ***
Entry: ON
Lockout: OFF
SAME Entry 2:
Code: 048113
Event: ***
Entry: ON
Lockout: ON
The above combination of entries for 048113 will not receive any SAME messages for 048113, since the
second entry is ON, with lockout ON, and with *** (all events wildcard) in the event field.
The entry lockout feature should be used with caution so as not to inadvertently lock out desired SAME
location or event codes.
Entering SAME Location and Event Codes
The following steps are used to create a SAME entry that provides all weather alerts for a given location.
Press the WX key to enter Weather mode.
Press the SAME softkey to add or edit SAME entries. The scanner display will show the following:
illust
Use the ^ or v keys on the 5-way pushbutton pad to scroll to the desired SAME code entry.
Press the SEL key on the 5-way pushbutton pad to edit the selected SAME entry. The scanner display will
appear as follows:
illust
With the Entry: field selected, press > on the 5-way pushbutton pad to turn the entry on.
Scroll to the Code: field and press > on the 5-way pushbutton pad to enter a SAME location code. Use the
keypad to enter a SAME code.
NOTE: The PSR-310 supports entry of Extended SAME codes, which can include numbers and letters.
The text entry mode is used to enter both numerical SAME codes and extended SAME codes. To enter a
numerical SAME code, simply precede each number in the SAME code with “1”. For example, to enter
SAME code 048113, press 10 14 18 11 11 13.
Scroll to the Event: field. Note the current default of ***, which will allow all messages for the specified
SAME location code. We recommend that you leave the event code with “***” to receive all alerts.
Scroll to the Tag: field. We suggest that you enter a tag name here that corresponds with the SAME
location code that you have entered. Press > on the 5-way pushbutton pad to edit the tag name, and use
the standard text entry method to enter your tag. Using our Dallas County example, you would enter the
following:
31 D
21 A
53 L
53 L
21 A
74 S
. <space>
23 C
63 O
82 U
62 N
81 T
93 Y
Scroll to the Alarm: field. Note that you can specify different alarm sounds for this SAME entry. We
recommend that you use the default setting here for general purpose weather alerting.
Scroll to the Lockout: field. Note that Lockout is currently set to off. Lockout is a special purpose parameter
that can be used to lock out individual event or area codes. We recommend that you leave Lockout set to
off for general purpose weather alerting.
When you have finished editing your SAME entry, press the Save softkey to store the data, then press the
Save softkey to save all SAME changes and return to the Weather mode.
Activating SAME Standby Mode
After you have entered your desired SAME codes, you can activate the SAME Standby Mode to begin
standby operation. The radio will remain silent until a SAME transmission is received with a code that
matches one that you have stored. When a matching SAME message is received, your radio will sound a
siren alarm, then will play the audio message that follows the Warning Alert Tone (WAT).
To activate SAME standby mode, press the WX key, use the ^ or v keys to find the best weather radio
transmitter for your location, then press the stby softkey. The softkey will change to STBY to indicate that
SAME Standby Mode is active, and the scanner will alert when a matching SAME message is received.
Press the STBY softkey again to exit SAME Standby Mode, or press MAN, SCAN or PGM.
When your local NWS office activates a SAME warning that matches a FIPS code stored in your scanner,
you will first hear a siren alarm and see the LED flash to alert you to the incoming alarm. The LED flashes
RED for warnings, YELLOW for watches, and BLUE for tests and administrative messages.
The scanner sounds the siren until the NWS transmission of the 1050 Hz Warning Alert Tone (WAT) begins.
Once the WAT begins, the scanner’s speaker will unmute, and you will hear the WAT play as an alert that
the voice portion of the SAME warning is about to begin. You will then hear the voice portion of the SAME
warning.
Your scanner will resume SAME Standby operation 90 seconds after the SAME warning starts. You may
reset standby mode by pressing the STBY softkey twice at any time.
Cloning Your Radio to Another PSR-310 or PSR-410 Scanner
Your PSR-310 features a high speed data interface that can be used to transfer the data from your scanner
to another PSR-310 or PSR-410 scanner from GRE.
To clone your radio to another unit, use a standard stereo patch cord terminated with 1/8” male stereo
phone plugs on each end to connect your radio (the SOURCE radio) to another radio (the TARGET radio).
Ensure that both radios are powered on. Press the PGM key, then the GLOB softkey to enter the Global
Settings menu. On the SOURCE radio, scroll to the Clone Send: option, then press the SEL key when you
are ready to send data from your SOURCE radio to the TARGET radio. Both working memory and global
settings are transferred.
Under certain circumstances the CCDump output may interfere with the cloning process. If you experience
problems with cloning, ensure that CCDump is turned off by pressing the PGM key, then the FUNC key,
then the GLOB softkey, then scrolling to the CCDump menu item. If necessary, turn CCDump off by
pressing the left or right arrow key, then press the Save softkey to save the setting.
NOTE: The contents of working memory on the TARGET radio will be overwritten immediately when SEL is
pressed on the SOURCE radio.
Standard Text Entry Method and QuickText
Your PSR-310 features a high-contrast, backlit alphanumeric display that provides constant feedback
about what the radio is doing while scanning and monitoring your “Scannable Objects”. To get the most out
of your scanner and this display, you will want to name your objects as you program them into the radio.
This allows for easy identification of active objects while the radio is scanning, and makes it easier than
ever to find objects that you wish to monitor, edit or delete using the powerful FIND feature.
Your scanner uses a simple text entry method that allows entry of all uppercase and lowercase letters of
the alphabet, numbers, and punctuation symbols. Your scanner also features GRE's exclusive QuickText
feature, which allows you to store up to 10 commonly used text items for instant recall while editing
alphanumeric fields.
Entering and Editing Alphanumeric Information
A Standard Text Entry Method is used for entering alphanumeric information into the radio. This method
allows easy access to each letter in the alphabet by pressing two keys that represent the letter.
Take a moment to study the numeric keys on the keypad and you will notice that keys 2-9 each have three
or four letters silk screened on the front panel just above each key. To enter a letter in an alphanumeric text
field, simply press the number key below the letter you wish to type first, then press the number key that
corresponds with the position of the letter in the silk screen group. For example, the number 2 is used to
access the letters A, B and C. To type the letter A, press 2 to select the ABC group, then 1 to select the first
letter in the group, A. Likewise, to type the letter B, press 2 to select the ABC group, then press 2 again to
select the second letter in the group. And, to type the letter C, simply press 2, then 3 to select the third letter
in the “ABC” group.
To enter numbers in alphanumeric text fields, press 1 first, then the number you wish to type.
To enter punctuation, press 0 first to see the first set of punctuation, then press the number key that
corresponds with the position of the desired punctuation mark in the set.
Press the . (period) key to enter a SPACE.
While using Standard Text Entry, the FUNC key serves as a shift key. For letters, uppercase text is typed by
default, and you can shift to lowercase by pressing the FUNC key before entering a character. For
punctuation, the FUNC key accesses a second set of punctuation marks. The shift action of the FUNC key
remains active until it is pressed again.
Use the <> keys to move the cursor to the desired location in edit fields. Press FUNC < or FUNC > to move
the cursor to the beginning or end of an edit field, respectively. Use the CL key as a backspace key to erase
characters before the cursor, and press FUNC CL to clear the entire field.
The PSR-310 character set and corresponding entry codes are provided below for reference. Pressing
FUNC to toggle the shift lock status will produce lower case characters for letters, and a second set of
punctuation marks for special characters. For brevity, lower case letters are not shown in the table below.
Char Code Char Code Char Code Char Code

Using QuickText
QuickText allows you to store up to 10 commonly used text items for instant recall while editing
alphanumeric fields. For example, as you search for, store and name new CONV or TGRP objects, you
may find that you type the same words over and over, such as POLICE, FIRE, SHERIFF, STATE, CITY,
COUNTY, etc.
A few common QuickText words are provided for your convenience. You can keep these, edit them to your
preferences, or replace them with your own custom QuickText words.
QuickText can be used while editing any alphanumeric text field. To insert a stored QuickText item, while
editing an alphanumeric text field use the <> keys to position the cursor where you what the QuickText
inserted, then press the QTXT softkey. The top row of the display will show the available QuickText phrases.
Use the ^v keys to scroll through the stored QuickText phrases, and press SEL to insert the QuickText
phrase at the cursor location. As a shortcut, you may press the number key on the numeric keypad that
corresponds with the QuickText item you wish to use, instead of scrolling and pressing SEL.
Customizing QuickText
To edit the QuickText words, press PGM, then the GLOB softkey. Scroll down to the QTXT section using
the v key on the 5-way pushbutton pad and find the QTXT storage location that you wish to change. Press
the > key to edit the QTXT entry. Use the standard text entry method to enter your desired text. When you
use your QTXT entry in a text field, any unused spaces will be filled with space characters. If you want to
leave room for additional text after the QTXT is loaded into a text field, include a space after your text, then
a dollar sign ($). This will place one space after your QTXT when you use your QTXT in a text field, and the
edit cursor will be positioned just after that space where you can continue appending text in the text field
before you save it. For example, if you use the entry SHERIFF in the QTXT storage location, your text entry
field will look like this after you load the QTXT “SHERIFF”:
SHERIFF !←note that cursor is positioned at end of text field
if you use the entry SHERIFF $ in the QTXT storage location, your text entry field will look like this after you
load the QTXT “SHERIFF”:
SHERIFF !←note that cursor is positioned at end of the word
Once you are finished editing your QTXT storage location, press the SAVE softkey to save the QTXT, then
press the SAVE softkey again to save the changes you made to the GLOB menu.
Power-On Configuration Key Sequences
Your PSR-310 features power-on keypress sequences that are used as shortcuts to configuration items,
like attenuator settings, backlight settings and memory information. Power-on key sequences are also used
to place your scanner into firmware upgrade mode for CPU firmware upgrades.
The following table lists the power-on key sequences available in the PSR-310. Unless otherwise specified,
each sequence is invoked by pressing and releasing each key in sequence, one at a time. The first key
must be pressed while the Welcome/Owner screen is being displayed:
Key Sequence Function
1 Shortcut to PGM>GLOB>Sound Mode
2 Shortcut to PGM>GLOB>Key Beeps

Birdie Frequencies
Every scanner has birdie frequencies. Birdies are signals created inside the scanner's receiver. These
operating frequencies might 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 SQ clockwise to omit the birdie.
To find the birdies in your scanner, begin by disconnecting the antenna and moving it away from the
scanner. Make sure that no other nearby radio or TV sets are turned on near the scanner. Use the TUNE
function and scan 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. This is a birdie. Make a list of all the
birdies in your scanner for future reference.
Care
Keep the scanner dry; if it 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.
Modifying or tampering with the scanner’s internal components can cause a malfunction and might
invalidate its warranty and void your FCC authorization to operate it.
The radio design of the tuning, control and filtering circuitry on the receiver is controlled by the serial data
from the firmware code in the microprocessor, which is built-in by the microprocessor manufacture as a part
of the internal design of the processor.
Since the processor information is inaccessible to the user, if someone attempt modifying circuitry without
the knowledge of the firmware code, the radio simply will fail to operate.
In Case of Fault
If you believe your scanner is defective, you should contact your dealer for assistance. However, before
you do so, check that the fault was caused by a human error. Carefully reread the relevant section in the
Owners Manual.
Troubleshooting
If you have problems with your scanner, please refer to the following chart for some suggestions that might
help you eliminate the problem. If the scanner is still not operating correctly after trying these tips, contact

Detailed Menu Reference
Your PSR-310 scanner uses GRE's exclusive Object Oriented User Interface, which features a powerful
menu system that is used to configure the various Scannable Objects that your scanner is capable of
receiving. The PSR-310 design also includes a Global Settings (GLOB) menu that provides unprecedented
control over the radio wide settings used throughout your scanner. This section of the manual provides
detailed information about all of the menus and menu parameters.
Each menu parameter features a Dflt softkey that can be used to restore the value to the factory defaults.
This can be very useful if you make a change to a parameter but do not like the result.
HINT: Remember that context sensitive help is available for every menu parameter. Press FUNC SEL to
view help for the selected parameter. Press SEL to exit help.
HINT: It's easy to fix things if you inadvertently change a parameter and then can't remember how to make
it right again. Each parameter includes a Dflt softkey, which, when pressed, restores the factory default
setting for that parameter.
HINT: If you think you've really messed the Global settings up, you can reset every global parameter
back to factory defaults without altering your programmed objects. Turn the radio off, then on again. While
the “Welcome” screen is being displayed, press and release 0, then press and release 2. Press ENT
to confirm the reset of all global parameters to their factory defaults.
NOTE: The Special Global Settings menu (FUNC GLOB) includes parameter settings that, if not set
properly, may adversely affect the performance of your radio. We recommend that users not change the
settings found in the FUNC GLOB menu unless instructed to in this manual or directed to do so by GRE
Technical Support personnel. Should you experience difficulties after changing any of the settings in the
FUNC GLOB menu, you can also restore those settings to factory defaults by pressing the Dflt softkey
associated with each menu line, or following the 0,2 global settings reset procedure described above.
GLOB Menu Reference
The GLOB menu stores all of the radio-wide settings used by the scanner. The GLOB menu allows you to
“tweak” these settings to your liking. The default settings will work fine for most users, but most users will
want to use the GLOB menu to personalize the radio to suit their individual tastes. The active parameter is
always the middle parameter and is indicated by a flashing “:”. The entire GLOB menu is shown below.
Note that some GLOB parameter changes do not take effect until the GLOB menu is saved.
HINT: You can restore all GLOB settings to their defaults without affecting your programmed objects. Power
cycle the radio, then press 0, then 2 during the welcome message display. Press ENT to confirm the GLOB
parameter reset.

Appendix A - Remote Control Protocol
NOTE: GRE provides Memory File Format, CCDump Protocol, PC/IF Clone Protocol and Remote Control
Protocol Specifications (the "Specifications") AS IS for the convenience of scanning hobbyists and
programmers who wish to develop software applications for use with the PSR-310. Use of the
Specifications shall be AT YOUR OWN RISK. GRE does not provide Memory File Format, CCDump
Protocol, PC/IF Clone Protocol and Remote Control Protocol technical support. Should you require
assistance with the Specifications, we encourage you to visit one of the many PSR-310 User Group forums
on the Internet. By using the Specifications, you agree to these terms.
The PSR-310 includes a simple remote control interface protocol (RCIP) that is suitable for use with a PC
application designed to provide a remote control and display capability. The ideal PC application should
provide a means by which a user can interact with a visual representation of the scanner's keypad and
display.
Remote Control Mode is active at all times, and does not require that the radio be placed in any special
remote mode in order for it to be used.
The basic remote control command/response format is as follows:
<STX><msgCode><msgData><ETX><sum>
where:
<STX> is an ASCII “Start of Text” symbol (0x02)
<msgCode> is the code that represents the command or response message type
<msgData> is the data that accompanies a command or a response
<ETX> is an ASCII “End of Text” symbol (0x03)
<sum> is the sum of all bytes before sum but not including <STX>, and is sent with every command and
response for error checking.

Appendix B – CCDump
NOTE: GRE provides Memory File Format, CCDump Protocol, PC/IF Clone Protocol and Remote Control
Protocol Specifications (the "Specifications") AS IS for the convenience of scanning hobbyists and
programmers who wish to develop software applications for use with the PSR-310. Use of the
Specifications shall be AT YOUR OWN RISK. GRE does not provide Memory File Format, CCDump
Protocol, PC/IF Clone Protocol and Remote Control Protocol technical support. Should you require
assistance with the Specifications, we encourage you to visit one of the many PSR-310 User Group forums
on the Internet. By using the Specifications, you agree to these terms.
Your PSR-310 features a trunked control channel decoding utility called CCDump. When CCDump is
turned on, the scanner sends decoded trunking control channel information and SAME weather alert data
to the PC/IF port. This data can be displayed using any simple terminal application, or, read by third party
application software for additional analysis and decoding.
CCDump is turned off by default in the PSR-310. To activate CCDump, press the PGM key, then press
FUNC, then press the GLOB softkey to access the Special Global Settings menu. Scroll down using the v
key until CCDump: No is shown on the middle line of the LCD display. Press the <> keys to toggle
CCDump on or off. Press the SAVE softkey when finished to save the change in the radio's configuration
memory.
To view CCDump data, connect the radio to a personal computer using the USB PC/IF cable. Start a
terminal program or your third party application software. Configure the communications parameters for
“115200, N, 8, 1” as follows:
COM Port: The COM port number assigned to the USB cable by your computer. If you are running
a Windows operating system, you can find this information under “Ports” in the Device Manager.
Parity: None
Baud Rate: 115,000 bits per second
Word: 8 bits
Stop Bits 1
Basic CCDump data includes the system type, the Object ID of the TSYS object (if applicable), and the
“raw” control channel messages as they are transmitted by the system. This data is delimited by “:”
symbols. Basic CCDump data is sent to the PC/IF port under the following conditions:
. In TUNE mode, when the radio is tuned to a trunking control channel
. In TSYS analysis mode, when the radio is tuned to an active control channel in the TSYS channel list
Expanded CCDump data includes all of the data that is provided in the Basic CCDump data display, and
provides additional human-readable decoding of certain trunked control channel messages. Expanded
CCDump data is sent to the PC/IF port under the following condition:
. When the radio is monitoring a trunked control channel while in MAN or SCAN modes
Under certain circumstances the CCDump output may interfere with the cloning process. If you experience
problems with cloning, ensure that CCDump is turned off by pressing the PGM key, then the FUNC key,
then the GLOB softkey, then scrolling to the CCDump menu item. If necessary, turn CCDump off by
pressing the left or right arrow key, then press the Save softkey to save the setting.
The following describes the CCDump message format for the supported modes:
<Msg Type>:T<xxxx>:<CC data>[:<Expanded CCDump description>]
<Msg Type>= always 3 ASCII chars:
WXS (WX SAME)
WXT (WX 1050Hz tone)
M36, LTR, EDW, EDN
<xxxx> = the hexadecimal representation of the TSYS's File System ID (for WXS and WXT,
this is the current Wx Chan 0-6, if in TUNE mode, “AAAA”)
<CC data> = the "osw" from the CC. The format necessarily
depends on the system type:
M36: <cmd> <dir> <id>
<cmd> = 3-digit (10-bit) hex "command" value
<dir> = direction bit
<id> = 4-digit (16-bit) hex "id" value
LTR: <RR>: <A>-<GG>-<HH>-<III>-<FF>
<RR> = repeater on which the msg was received
<A> = area
<GG> = Goto/In-Use repeater #
<HH> = Home Repeater #
<III> = Group ID
<FF> = Free Repeater #
EDW: <W>: <ccc> <ppppppp>
<W> = which of the two blocks (0 or 1) in the msg pair this is <ccc> =
command value. Represents a variable # of bits from the received data (since
commands are variable length)
<payload> = remainder of msg, after removing the <ccc> command value
EDN: <W>: <ccc> <ppppppp>
<W> = which of the two blocks (0 or 1) in the msg pair this is
<ccc> = command value. Represents a variable # of bits from the received
data (since commands are variable length)
<ppppppp> = remainder of msg, after removing the <ccc> command value
WXS: <SAME Message> One code at a time
WXT: "1050Hz Detect"
<decoded description> = If present, how the radio SW interpreted the msg.

Appendix E - Finding More Information
Learning About Scanning and your PSR-310
In recent years the Internet has become a powerful tool for both experienced and novice scanning
hobbyists. There are many online discussion forums dedicated to the scanning hobby. In these discussion
forums, you will find users helping other users with questions about radio systems, scanning receivers,
antenna setups, and frequency listings for different areas.
One of the most useful resources on the Internet are discussion forums devoted to specific radio models.
Frequently you will find other users who are willing to answer questions or help you solve problems with
your scanning equipment.
In many cases a simple Web search using Google or other popular Internet search tools will help you find
web sites and discussion forums where you can read more about the PSR-310, ask questions, and share
your experiences with other PSR-310 users.
For starters, we recommend www.radioreference.com, where you will find a discussion forum dedicated to
the PSR-310, along with dozens of other scanning discussion forums devoted to the scanning hobby.
We also suggest groups.yahoo.com. Search the Yahoo Groups for PSR-310, and join groups that include
active discussions related to the PSR-310.
And, be sure to visit www.greamerica.com frequently for important news, software updates and information
about exciting new GRE Scanning Receiver products and accessories!
Finding Frequencies and Trunked System Information
Research is an important part of the scanning hobby. Before you can listen, you must first figure out what
you want to listen to, and then perform the research necessary to obtain the conventional frequency or
trunked radio system information needed to program your radio.
Sometimes, a simple Web search using Google or other popular Internet search tools is all that you need to
get started. Try searching on “<name of city or county> scanner frequencies” or “<name of city or county>
frequencies” (omitting the quotation marks and < > symbols) to locate personal web pages with information
about scanning in the specified areas. We also suggest www.radioreference.com, which includes an
extensive database of conventional and trunked radio system data for locations all over the USA and the
world.
One of the more enjoyable aspects of the scanning hobby is finding new frequencies on your own. Your
PSR-310 includes powerful Limit Search (LMIT) and Service Search (SRVC) search capabilities that will
help you find active frequencies in your area, and a Spectrum Sweeper (SWPR) that quickly searches
through selected frequency bands to find nearby transmitters.
