ST290 Instrument System Owner’s Handbook
Chapter 1: An Introduction to Digital
Instruments
1.1 Overview
The ST290 system uses Graphic and Data Display digital instrument
types. The Graphic Display uses a dot-matrix screen, which gives
flexibility in the way data can be displayed, and offers a wide range of
display formats, including graphs and animations. The Data Display has
a clear, easy-to-read LCD screen, with upper and lower display areas.

Chapter & page structures
Information on both digital instrument types is organized in ‘chapters’
and ‘pages’, to enable you to easily find the data you want. Details on the
chapter and page structures of the profiles available for each instrument
type are given in Section 2, Chapter 2, Graphic Display and Chapter 3,
Data Display.
In this handbook it is assumed that all instrument chapters and pages are
available. However, it is important to realize that some chapters and
pages may not be available, for one or more of the following reasons:
• The relevant transducers may not be fitted on your vessel, or trans-
ducer data may not be available.
• Some chapters and pages may have been disabled during customiza-
tion (see Section 7, System Setup).
• Some chapters and pages may not be supported by the operating pro-
fileapplied totheinstrument you are using.See Operating profiles on
page 2-1-6 of this chapter.
