"DANGER", "WARNING" and "CAUTION" notices appear throughout this manual. It is the responsibility of the operator of the equipment to read, understand and follow these notices. If you have any questions regarding these safety instructions, please contact a FURUNO agent or dealer.
DANGER
WARNING
CAUTION
This notice indicates a potentially hazardous situation which, if not avoided, will result in death or serious injury.
This notice indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
This notice indicates an unsafe practice which, if not avoided, could result in minor or moderate injury, or property damage.
i
DANGER
This equipment uses high voltage electricity which can shock, burn or cause death.
Only qualified personnel should work inside the enclosures.
Do not diassemble or modify the equipment.
Fire, electrical shock or serious injury can result.
DANGER
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.
Serious injury or death can result if the radiator starts rotating and strikes someone near the scanner unit.
Wear a safety belt and hard hat when working on the antenna unit.
Serious injury or death can result if someone falls from the scanner mast.
ii
Radio Frequency Radation 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/m |
exist are given in the table below. |

WARNING
Turn off the power at the mains switchboard if metallic object or liquid falls into the equipment.
Continued use can result in electrical shock or fire.
Use the correct fuse.
Use of the wrong fuse can cause fire or electrical shock.
Ensure no water splash or rain leaks into the equipment.
Water in the equipment can result in fire or electrical shock.
Turn off the power at the mains switchboard if the unit is emitting smoke or fire.
Continued use can result in fire or electrical shock.
Do not place liquid-filled containers on the top of the equipment.
Fire or electrical shock can result if a liquid leaks into the equipment.
Keep heaters away from the equipment.
Heat can melt the power cord, which can result in fire or electrical shock.
CAUTION
Immediately turn off the power whenever you feel the equipment is abnormal.
Continued use can cause equipment damage.
Keep magnets and magnetic fields (speaker, transformer, etc.) way from the equipment.
Magnets and magnetic fields can cause equipment malfunction.
iv

DANGER
Before turning on the radar, make sure no one is near the antenna unit. Serious injury or death can result if a rotating antenna strikes someone standing nearby.
The range selected automatically determines the range ring interval, the number of range rings and pulse repetition rate, for optimal detection capability in short to long ranges.

Turning on the radar
Press the POWER key. The control panel lights and a timer displays the time remaining for warm up of the magnetron, counting down from 3:00 to 0:00.
Turning off the radar
Press POWER and ST BY/TX keys together.
Transmitting
After the power is turned on and the magnetron has warmed up, ST-BY (Stand-By) appears at the screen center, indicating the radar is ready to transmit radar pulses. In stand-by the radar is available for use at any time.
Press the ST BY/TX key to transmit. The radar displays echoes in eight intensities according to echo strength.
Stand-by
When you won’t be using the radar for an extended period, but you want to keep it in a state of readiness, place it in stand-by by pressing the ST BY/TX key. The display shows ST-BY.
Figure 1-4 Location of range, range ring interval and pulselength indications
Procedure
Press the RANGE key at + or –. The range, range ring interval and pulselength appear at the top left corner of the display.
1 – 4
This radar has the following presentation modes:
Relative Motion (RM)
Head-up: Unstabilized
Course-up: Compass-stabilized relative to ship’s intended course
North-up: Compass-stabilized with reference to north
True Motion (TM)
North-up: Ground or sea stabilized with compass and speed inputs
Selecting presentation mode
Each time the MODE key is pressed, the presentation mode and mode indication at the upperleft corner of the screen change cyclically.
Loss of gyro signal
When the gyro signal is lost, the presentation mode automatically becomes Head-up and the HDG readout at the screen top shows
xxx.x. The x's do not disappear even when the gyro signal is restored, to warn the operator that the readout may be unreliable.
Match the gyro readout with the gyrocompass reading. Press the MODE key.
