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 require-
ments 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 Scan-
nable 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 scan-
ner 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 talk-
group, 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 en-
tirety 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 program-
ming your favorite "objects" into the radio.
