Cd In the USA The Mobius loop symbol (three chasing arrows) indicates that Ni-Cd and lead-acid rechargeable batteries must be recycled. Take the used batteries to a battery collection site according to local laws. Ni-Cd Pb In the other countries There are no international standards for the battery recycle symbol. The number of symbols can increase when the other countries make their own recycle symbols in the future. SAFETY INSTRUCTIONS Read these safety instructions before you operate the equipment. WARNING Indicates a condition that can cause death or serious injury if not avoided. CAUTION Indicates a condition that can cause minor or moderate injury if not avoided. Warning, Caution Prohibitive Action Mandatory Action WARNING Radio Frequency Radiation Hazard 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. 100W/m2 10W/m2 XN-12A N/A 1.1m XN-13A N/A 1.0m XN-12A N/A 1.9m XN-13A N/A 1.7m XN-12A N/A 2.1m XN-13A N/A 1.9m XN-12A 0.6m 4.6m XN-13A 0.4m 3.1m Model FR-8045 FR-8065 FR-8125 FR-8255 ii SAFETY INSTRUCTIONS WARNING ELECTRICAL SHOCK HAZARD WARNING Use the correct fuse. Do not open the equipment. Only qualified persons can work inside the equipment. Turn off the power before you service the antenna unit. Post a warning sign near the power switch not to turn on the power while you service the antenna unit. Prevent the potential risk of being struck by the rotating antenna and exposure to RF radiation hazard. Do not disassemble or modify the equipment. A wrong fuse can damage the equipment and cause fire. Keep heater away from the equipment. Heat can change the equipment shape and melt the power cord, which can cause fire or electrical shock. Do not put liquid-filled containers on the top of the equipment. Fire or electrical shock can occur if a liquid spills into the equipment. Do not operate the equipment with wet hands. Fire or electrical shock can occur. Electrical shock can occur. Turn off the power immediately if water leaks into the equipment or smoke or fire is coming from the equipment. Failure to turn off the equipment can cause fire or electrical shock. iii SAFETY INSTRUCTIONS WARNING Do not depend on one navigation device for the navigation of the ship. The navigator must check all aids available to confirm position. Electronic aids are not a replacement for basic navigation principles 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. CAUTION The plotting accuracy and response of this ARPA meets IMO standards. The tracking accuracy is affected by the following: · 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 are intended for reference purposes only. Check all available navigation aids to determine target movement. WARNING LABELS 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 Radiation hazard. Only qualified personnel should work inside scanner. Confirm that TX has stopped before opening scanner. iv ANTENNA UNIT Name: Warning Sticker Type: 03-142-3201-0 Code No.: 100-266-890-10 TFT LCD The high quality TFT (Thin Film Transistor) LCD displays 99.999% of its picture elements. The remaining 0.001% may drop out or light, however this is an inherent property of the LCD; it is not a sign of malfunction.
