Scope Of This Manual
This manual reflects the software capabilities in version 2.0 software.
We have attempted to take care and develop manuals which provide
in-depth information. Where possible, we have attempted not only to
describe what you see on the screen, but how to understand and use
it as well. Obviously, we can’t teach you how to navigate, but we can
help make your work more thorough and enjoyable. Throughout the
manual, you will find helpful hints about the interaction of various
functions. In a piece of equipment that has the many capabilities of
this receiver, important details can sometimes become obscured in one
or two lines of text. In our effort to ensure you get the most out of this
documentation, and to protect against important details becoming lost,
don’t be surprised if you see the same or similar information more than
once.
This manual is organized by describing first the various MX420 mod-
els covered in this book. Then the special front panel features includ-
ing the traffic light indicator. The sections that follow detail each pri-
mary function as it is presented on the front panel (i.e. NAV, RTE, WPT,
PLOT, ...CFG). The appedixes describe important details about special
functions.
Appendix-A is a special section describing the AIS displays and set-
ups of the MX420/AIS model.
We hope you find the manual enjoyable and informative reading. As
always, we welcome your comments on improving our products or
manuals. We wouldn’t mind if you wrote to tell us that we did the job
right the first time either. You can find a Reader Comment Card at the
back of the manual.
