ii SAFETY INSTRUCTIONSWARNINGRadio Frequency Radiation HazardWARNINGIndicates a condition that can cause death or serious injury if not avoided.CAUTIONIndicates a condition that can cause minor or moderate injury if not avoided. Warning, Caution Mandatory ActionProhibitive ActionRead these safety instructions before you operate the equipment. The radar antenna sends the electromagnetic radio frequency (RF) energy. This energy can be dangerous to you, especially your eyes. Do not look at the radiator or near the antenna when the antenna is rotating.The distances at which RF radiation levels of 100 W/m2 and 10 W/m2 exist are shown in the table.Note: If the antenna unit is installed at a close distance in front of the wheel house, prevent the transmission in that area to protect passengers and crew from microwave radiation. Set the [Sector Blanks] in the [System] menu.FR-8065100W/m210W/m2FR-8125FR-8255FR-8045ModelXN-12AXN-13AXN-12AXN-13AXN-12AXN-13AXN-12AXN-13A N/AN/AN/AN/AN/AN/A1.1m1.0m1.9m0.6m0.4m 3.1m4.6m1.7m2.1m1.9m
SAFETY INSTRUCTIONSiiiWARNINGELECTRICAL SHOCK HAZARDDo not open the equipment.Only qualified persons can workinside the equipment.Turn off the power before youservice the antenna unit. Post awarning sign near the powerswitch not to turn on the powerwhile you service the antennaunit.Prevent the potential risk of beingstruck by the rotating antenna andexposure to RF radiation hazard.Do not disassemble or modifythe equipment.Fire or electrical shock can occur.Turn off the power immediatelyif water leaks into the equipmentor smoke or fire is comingfrom the equipment.Failure to turn off the equipmentcan cause fire or electrical shock.Use the correct fuse.A wrong fuse can damage theequipment and cause fire.Keep heater away from theequipment.Heat can change the equipmentshape and melt the power cord, whichcan cause fire or electrical shock.Do not put liquid-filled containerson the top of the equipment.Fire or electrical shock can occur if aliquid spills into the equipment.Do not operate the equipment withwet hands.Electrical shock can occur.WARNING
SAFETY INSTRUCTIONSivDo not depend on one navigationdevice for the navigation of theship. The navigator must check allaids available to confirm position.Electronic aids are not areplacement for basic navigationprinciples and common sense.· The ARPA automatically tracks an automatically or manually acquired radar target and calculates its course and speed, indicating them by a vector. Since the data from the auto plotter depend on the selected radar targets, the radar must be optimally tuned for use with the auto plotter, to ensure required targets will not be lost or unnecessary targets like sea returns and noise will not be acquired and tracked.· A target is not always a landmass, reef, ship, but can also be returns from the sea surface and from clutter. As the level of clutter changes with the environment, the operator must correctly adjust the A/C SEA, A/C RAIN and GAIN controls so that the target echoes do not disappear from the radar screen.CAUTIONCAUTIONThe plotting accuracy and response ofthis ARPA meets IMO standards.The tracking accuracy is affected by thefollowing:· The tracking accuracy is affected by course change. One to two minutes is required to restore vectors to full accuracy after a sudden 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 from ARPA and AIS areintended for reference purposes only.Check all available navigation aids to determine target movement.WARNING LABELSWarning labels are attached to the equipment. Do not remove any label. If a label is missing or damaged, contact a FURUNO agent or dealerabout replacement.WARNINGRadiation hazard. Only qualified personnel should work inside scanner.Confirm that TX has stopped beforeopening scanner.ANTENNA UNITTFT LCDThe high quality TFT (Thin FilmTransistor) LCD displays 99.999%of its picture elements.The remaining 0.001% may dropout or light, however this is aninherent property of the LCD; it isnot a sign of malfunction.WARNINGName: Warning StickerType: 03-142-3201-0Code No.: 100-266-890-10
