SAFETY INFORMATION

"DANGER", "W ARNING " 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 .

This notice indicates a potentially hazardous situation which, if not

WARNING

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.

DANGER

CAUTION

This notice indicates an unsafe practice which, if not avoided, could result in minor or moderate injury, or property damage.

iiiiiiiiiiiii

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.

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.

WARNING

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

CAUTION

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.

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.

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.

1.1 Turning the Radar On/Off

DANGER

1.3 Selecting Range

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.

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.

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.

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.

1.4 Presentation Mode

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.

Description

A display withouth azimuth stabilization in which the line connecting the center with the top of the display indicates own ship's heading.

The target pips are painted at their measured distances and in their directions relative to own ship's heading.

090

The short dashed line on the bearing scale is the north mark and it indicates compass north.

Failure of the gyro will remove the north marker and the HDG indication shows "xxx.x".

An azimuth stabilized display in which a line connecting the center with the top of the display indicates own ship's intended course (namely, own ship's previous heading just before this mode has been selected).

Target pips are painted at their measured distances and in their directions relative to the intended course which is maintained at the 0-degree position while the heading marker moves in accordance with the ship's yawing and course changes. This mode is useful to avoid smearing of picture during course changes. After a course change, press the SHIFT ZOOM key to reset the picture orientation if you wish to continue using the Course-up mode.

If the gyrocompass fails, the presentation mode changes to the Head-up mode and the north marker disappears. Also, the HDG readout at the screen top shows xxx.x.
