Chapter 1: Operational Overview
This chapter provides the information necessary to get you started using your multi
function display, from how to turn it on and off to how to read the main displays.
This manual shows dedicated keys in bold face upper case letter; for example, DISP.
All other labelled items such as ROTOkeys are shown in body text font.
1.1 Operating Controls
This multi function display comes with either the Control Unit (MCU-001) or DIsplay
Control Unit (DCU12). (Alternatively necessary software is incorporated in a PC.)
Their controls are identical except for the POWER switch; on the DCU12 it also func-
tions to adjust display brilliance.
Discrete keys whose key labels have two text labels separated by an underline carry
two functions. The top label is the main function and the bottom label, the secondary
function. You access those functions with a short push and long push, respectively.
You operate the chart plotter, radar, etc. with a combination of
• Twelve discrete keys
• Cursorpad
• Scrollingpad
•ROTOkey
• Menus, where you select options
• Pop-up menus, where you select options
• Lists, where you can edit items
When you operate a key a single beep sounds to confirm correct operation. For invalid
operation three beeps sound. If you do not need the key beep you may turn it off, in
the General menu.
