Heat can alter equipment shape and melt the power cord, which can cause fire or electrical shock.

WARNING

Radio Frequency

Radiation Hazard

The radar antenna emits electromagnetic radio frequency (RF) energy which can be harmful, particularly to your eyes. Never look directly into the antenna aperture from a close distance while the radar is in operation or expose yourself to the transmitting antenna at a close distance.

Distances at which RF radiation levels of 100 and 10 W/m2 exist are given in the table below.

Note: If the antenna unit is installed at a close distance in front of the wheel house, your administration may require halt of transmission within a certain sector of antenna revolution. This is possible - Ask your FURUNO representative or dealer to provide this feature.

SYSTEM CONFIGURATIONS

All NavNet products incorporate a “network circuit board” to integrate each NavNet product on board through an optional LAN cable (Ethernet 10BASE-T). Each NavNet product is assigned an IP address to enable transfer of images between other NavNet products. For example, video plotter pictures can be transferred to a radar and vice versa. Pictures received via the NavNet may be adjusted at the receiving end.

The number of display units which may be installed depends on the number of network sounder connected. For a system incorporating three or more products, a “hub” is required to process data.

For one network sounder: one radar and three plotters, or four plotters For two network sounder: one radar and two plotters, or four plotters

Note: NavNet2 equipment cannot be connected to initial version NavNet equipment.

1. OPERATIONAL OVERVIEW

This chapter provides the basic information needed to get you started using your radar, video plotter.

1.1Operating Controls

Display unit controls

The radar, video plotter, sounder and chart systems are operated with the controls of the display unit. Ten keys are labeled and they provide the function shown on their labels. The five soft keys provide various functions according to current operating mode. The ENTER knob mainly functions to register selections on the menu and adjust the EBL, VRM and gain. The Trackball’s main function is to move the cursor across the screen. When you correctly execute an operation, the unit generates a beep. Invalid operation causes the unit to emit three beeps.

The simulation display, for use by service technicians for demonstration purposes, provides simulated operation to help acquaint you with the many features your unit has to offer. It allows you to view and control a simulated plotter, radar and sounder picture, without position-fixing equipment, network radar or a network sounder. Most controls are operative, thus you may practice setting destination, enter waypoints, measure range and bearing to a target, etc. Three simulation displays are provided for both the radar and echo sounder.

The simulation icon (SIM) appears when any simulation mode is active.

To start the simulation display;

1.Press the MENU key.

2.Press the SYSTEM CONFIGURATION, SYSTEM SETUP and SIMULATION SETUP soft keys in that order.
