1) Intuitive "Object Oriented" User Interface Design - 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.
2) Powerful and Flexible Scan List Functionality Allows you to arrange, group and scan objects according to your
preference, with no limit to the number or types of objects in a Scan List, and no limit to the number of Scan Lists
an object can be a member of.

3) 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.

4) Upgradeable CPU and DSP Firmware - You can easily keep your radio current with software enhancements as they
become available with free upgrades from our website!

5) 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.

6) GRE's Exclusive V-Scanner Technology - Allows you to save complete radio configurations within the radio, for
recall into main memory as needed in the field. This is similar to having a laptop computer and programming
software available anytime. You can use V-Scanners to store configurations for different geographical areas
or usage styles. Twenty-one V-Scanner Folders are provided, each capable of storing over 1,800 objects.
Total memory capacity of main memory combined with V-Scanners is over 39,600 (1,800+37,800) objects!

7) Multi-System Trunking - Scans most common trunked radio system signaling formats, including Motorola,
EDACS Standard, EDACS Narrow, LTR and P25 trunked radio networks. Talkgroup call and individual
call monitoring are supported. Supports trunking operation in virtually any land mobile radio band, including
700 MHz and the new Federal 380 MHz band!

8) P25 NAC Functionality - Much like CTCSS and DCS with analog signals, P25 Network Access Code (NAC)
is used to provide selective squelch operation on conventional P25 digital channels. GRE's PSR-500 Advanced
Digital Scanner will detect the NAC that is being used on a P25 conventional digital channel, and will allow
you to program NAC codes to block transmissions that do not have a matching NAC,
including analog traffic on the same frequency!

9) Remote Control Capability - Can be used with third party application software to remotely control the scanner
from a personal computer.

10) 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 objects are active, e.g., blue can be used to signal activity
on a primary police call, red for fire, etc."

11) Audible alarms - Programmable audible alarms can be configured to sound when certain objects are active.
Can be used in conjunction with, or separately from, the ALERT LED described above.

12) GRE's Exclusive Automatic Adaptive Digital Tracking - When monitoring Motorola and P25 digital systems,
instantly adapts the digital decoder to the digital modulation format of the transmitted signal, then analyzes
the digital signal 50 times each second and adapts to any subtle changes caused by multipath or fading.
No cumbersome manual adjustments are required.

13) GRE's Exclusive Digital AGC - Instantly compensates for low audio levels that are very common on digital
systems. The radio is easier to listen to, and provides you with a more enjoyable scanning experience.

14) The Best Subaudible Squelch Decoder in the Scanning Industry - CTCSS and DCS subaudible squelch
coding is processed by the same powerful DSP chip that is used for P25 digital decoding. Provides fast
and reliable decoding of subaudible squelch signaling with squelch tail elimination.

15) 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.

16) Powerful Spectrum Sweeper - Quickly sweeps the scanner's frequency ranges for transmissions from nearby
transmitters.

17) Real-time Signal Strength Indicator - Shows relative strength of received signals.

18) Trunking Control Data Output - Streams decoded trunking control data from your PSR-500 to a personal
computer for use with popular third party trunking control channel monitoring software. No slicer needed!
Also streams NOAA weather radio SAME alert data!

19) High Contrast LCD Display - Provides one row of dedicated icons, and four rows of 16 characters for
programming and scanning operations.

20) SAME and All Hazards Weather Alerting - GRE's PSR-500 Advanced Digital Scanner can operate in dedicated
SAME weather alerting mode, and alert you to severe weather and other hazards in the specific area(s) that you
select, or, the scanner can check your local NOAA weather frequency periodically, even while scanning, and alert
you when an All Hazards alert occurs.

21) SKYWARN Storm Spotter Functionality Provides instant, one button 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.
