System Introduction

This chapter provides the information necessary to get you started using your system.
Some of the topics are how to turn on the equipment and an introduction to the main
displays.
Standards used in this manual
• The keys and controls on the control panel are shown in bold face, for example the
DISP key. Other items that have a label, for example, the soft controls related to the
RotoKey, are shown in brackets in normal typeface. For example, [Head Up].
• The RotoKey controls the "soft controls", a revolving set of soft controls that gives
you access to full control of the NavNet 3D system. You rotate the RotoKey to se-
lect a soft control then push the RotoKey to do the function marked on the soft con-
trol. This manual states this operation procedure as "Use the RotoKey to select
[menu item name or soft control name]."
• The menu system has a maximum of 15 menus and related sub menus. When you
are asked to open a menu, the name of the menu and sub menu are given, sepa-
rated by a hyphen. For example, "Open the [Routes-General] menu".
• There is more than one method to do a function, Key operation, pop-up menu and
RotoKey.

The NavNet 3D System

The NavNet 3D network is a system where all parts use the same information (navi-
gation data, settings, points, routes, etc.). Each unit in the system displays information
from other units and NMEA devices, like GPS navigator. Information is transferred
between MFDs through a high-speed Ethernet.
Each MFD has a special "sleep mode" that allows each MFD to operate while using
low power. The MFDs can be in three states:
• ON: Normal mode of operation. The screen is on and the user can operate the MFD.
The MFD operates and transfers information across the network.
• Sleep Mode: The screen is turned OFF and only the power switch operates (to turn
the power OFF). The MFD in this state can process controls and transfer informa-
tion with other MFDs on the network. The MFD uses low current in this state.
• OFF: The MFD is turned OFF and does not control information. The MFD does not
use any current in this state.
When power is applied to an MFD (with the power switch), all the other MFDs start in
the sleep mode. If you operate the power switch on an MFD that is in the sleep mode,
the MFD turns on. If you press the power switch on an MFD more than three seconds,
all MFDs in the network are turned OFF.
Note: If you press a power switch more than 5-7 seconds, all MFDs turn OFF and
power synchronization is lost. To restore power synchronization, first turn off all MFDs.
Then, hold down the power switch of the MFD that was responsible for loss of power
synchronization for three seconds.
