How to discard a used battery
In the European Union
The crossed-out trash can symbol indicates that all types of batteries
must not be discarded in standard trash, or at a trash site. Take the
used batteries to a battery collection site according to your national
legislation and the Batteries Directive 2006/66/EU.
In the USA
The Mobius loop symbol (three chasing arrows) indicates that Ni-Cd
and lead-acid rechargeable batteries must be recycled. Take the fin-
ished batteries to a battery collection site according to local laws.
In the other countries
There are no international standards for the battery recycle symbol. The number of symbols can
increase when the other countries make their own recycle symbols in the future.

exist are shown in the table.
Do not open the equipment.
Only qualified persons can work inside
the equipment.
Check that no person is near the radar
antenna before you turn on the radar.
Serious injury or death can occur if a
person is hit by a rotating radar antenna.
Turn off the power immediately at the
switchboard if water leaks into the
equipment or smoke or fire is coming
from the equipment.

1. 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.
1.1 The NavNet 3D System
The NavNet 3D network is a system where all parts use the same information (navi-
gationdata, settings, points, routes,etc.). Each unit in thesystem 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:Normalmodeofoperation. Thescreenisonandthe user canoperatetheMFD.
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
powersynchronizationislost.To restore power synchronization,firstturnoffallMFDs.
Then, hold down the power switch of the MFD that was responsible for loss of power
synchronization for three seconds.

1.1.1 How to sleep the equipment
You can sleep the equipment when its use is not required continuously. With the Stan-
dard or Full RotoKey set active, push the RotoKey, rotate the key to select [Sleep]
then push the key. To un-sleep the equipment, push the power key until the picture
appears.
1.2 Controls
The controller for this system is either the MFD8 or MFD12.
A key that has two text labels separated by a line has two functions. The top label is
the main function and the bottom label, the secondary function. Short-push to access
the main function and long-push (approximately three seconds) to access the second-
ary function.
You operate the chart plotter, radar, fish finder, etc. with
• Keys
• CursorPad
• ScrollingPad
• RotoKey
• Menus, where you select options
• Pop-up menus, where you select options
• Lists, where you can edit items
Whenyou operate a key, a singlebeep sounds to tell you correctoperation.For wrong
operation, three beeps sound. If you do not need the key beep, deactivate the beep
sound from the [Global-General] menu.
