SAFETY INSTRUCTIONS

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.

SAFETY INSTRUCTIONS

WARNING

ELECTRICAL SHOCK HAZARD

Do not open the equipment.

Only qualified personnel should work inside the equipment.

Turn off the radar power switch before servicing the antenna unit. Post a warning sign near the switch indicating it should not be turned on while the antenna unit is being serviced.

Prevent the potential risk of being struck by the rotating antenna and exposure to RF radiation hazard.

Wear a safety belt and hard hat when working on the antenna unit.

Serious injury or death can result if someone falls from the radar antenna mast.

Do not disassemble or modify the equipment.

Fire, electrical shock or serious injury can result.

Immediately turn off the power at the ship's mains switchboard if water leaks into the equipment or the equipment is emitting smoke or fire.

Continued use can cause fatal damage to the equipment.

WARNING

Use the proper fuse.

Use of a wrong fuse can result in damage to the equipment or cause fire.

Keep heater away from equipment.

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

Do not place liquid-filled containers near the equipment.

Fire or electrical shock can result if a liquid spills into the equipment.

Do not operate the equipment with wet hands.

Electrical shock can result.

Before servicing the radar, turn off the appropriate external breaker.

Power is not removed from the radar simply by turning off its power switch.

WARNING

No one navigational aid should be relied upon for the safety of vessel and crew. The navigator has the responsibility to check all aids available to confirm position. Electronic aids are not

a substitute for basic navigational principles and common sense.

•This ARP automatically tracks automatically or manually acquired radar targets and calculates their courses and speeds, indicating them by vectors. Since the data generated by the auto plotter are based on what radar targets are selected, the radar must always be optimally tuned for use with the auto plotter, to ensure required targets will not be lost or unwanted targets such as sea returns and noise will not be acquired and tracked.

•A target does not always mean a landmass, reef, ships or other surface vessels but can imply returns from sea surface and clutter. As the level of clutter changes with environment, the operator should properly adjust the A/C SEA, A/C RAIN and GAIN controls to be sure target echoes are not eliminated from the

radar screen.

SAFETY INSTRUCTIONS

CAUTION

The plotting accuracy and response of this ARP meets IMO standards. Tracking accuracy is affected by the following:

•Tracking accuracy is affected by course change. One to two minutes is required to restore vectors to full accuracy after an abrupt course change. (The actual amount depends on gyrocompass specifications.)

•The amount of tracking delay is inversely proportional to the relative speed of the target. Delay is on the order of 15—30 seconds for high relative speed; 30—60 seconds for low relative speed.

The data generated by ARP, AIS and video plotter are intended for reference only.

Refer to official nautical charts for detailed and up-to-date information.

SAFETY INSTRUCTIONS

WARNING LABEL

Warning labels are attached to the equipment. Do not remove any label. If a label is missing or damaged, contact a FURUNO agent or dealer about replacement.

WARNING

To avoid electrical shock, do not remove cover. No user-serviceable parts inside.

WARNING

Radiation hazard. Only qualified personnel should work inside scanner. Confirm that TX has stopped before opening scanner.

FOREWORD

•Two types of trackball-equipped control units are available: RCU-014 (full keyboard) and the RCU-015 (palm control). The trackball is easy to use thanks to the ergonomically designed palm rest.

•Simplified operation with point-and-click menu operation.

•All functions are accessible by using the trackball alone.

•Applicable to HSC (High Speed Craft)

•ARPA (Automatic Radar Plotting Aid) or ATA (Automatic Tracking Aid) + AIS, Radar Plotter and Interswitch supplied as standard. (ARPA or ATA selectable on installation menu.)

•Meets the following requirements:

Precautions for high speed targets

Assume your ship is making 40 kt and a target ship is approaching at 49 kt right toward you. Then the relative speed is 80 kt. With the antenna rotating at 42 rpm, the target blip appears jumping to a new location 59 m nearer. This jump corresponds to 19 mm on the display using the 0.25 nm range scale. On such a short range you may lose the track of a target in the midst of sea clutter, random noise or other targets. Use one step larger range scale.

ARPA can fail to track a target when the relative speed exceeds 100 kt.

E3519S01C-M

1 RADAR OPERATION

1.1Turning on the Power

The [POWER] switch is located at the left corner of the control unit. Open the power switch cover and press the switch to turn on the radar system. To turn off the radar, press the switch again. The screen shows the bearing scale and digital timer approximately 30 seconds after power-on. The timer counts down three minutes of warm-up time. During this period the magnetron (transmitter tube) is warmed for transmission. When the timer has reached 0:00, the indication “ST-BY” appears at the screen center, meaning the radar is now ready to transmit pulses.

In the stand-by condition, markers, rings, map, charts, etc. are not shown. Further, ARP is cancelled and the AIS display is erased.

In warm-up and stand-by condition, ON TIME and TX TIME counts in hours and tenths of hour appear at the screen center.

1.2Transmitter ON

After the power is turned on and the magnetron has warmed up, ST-BY appears at the screen center, meaning the radar is ready to transmit radar pulses. You may transmit by pressing the [STBY/TX] key on the full keyboard or roll the trackball to choose the TX STBY box at the bottom left corner of the display and then push the left button (above the trackball). The label at the left-hand side of the guidance box at the bottom right corner of the screen changes from TX to STBY.

1. RADAR OPERATION

The radar is initially set to previously used range and pulse length. Other settings such as brilliance levels, VRMs, EBLs and menu option selections are also set to previous settings.

The [STBY/TX] key (or TX STBY box) toggles the radar between STBY and TRANSMIT status. The antenna stops in stand-by and rotates in transmit. The magnetron ages with time resulting in a reduction of output power. Therefore, it is highly recommended that the radar be set to stand-by when not used for an extended period of time.

Quick start

Provided that the radar was once in use with the transmitter tube (magnetron) still warm, you can turn the radar into TRANSMIT condition without three minutes of warm-up. If the [POWER] switch has been turned off by mistake or the like and you wish to restart the radar promptly, turn on the [POWER] switch not later than 10 seconds after power-off.
