Intruduction - Grecom PSR-410 Owner's Manual

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.
