ADB9ZWRTR087Marine Radar

MARINE RADAR FR-8062, FR-8122, FR-8252 i 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/m 2 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. MODEL Distance to 100 W/m 2 point Distance to 10 W/m 2 point FR-8062 Nil Worst case 2.50 m Worst case 2.30 m XN-12A XN-13A XN-12A XN-13A Worst case 0.50 m Worst case 0.30 m Worst case 7.50 m Worst case 7.00 m FR-8122 XN-12A XN-13A Worst case 0.80 m Worst case 0.70 m Worst case 9.50 m Worst case 9.00 m FR-8252 ii 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 warn- ing 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. Turn off the power immediately if water leaks into the equipment or the equip- ment is emitting smoke or fire. Continued use of the equipment can cause fire or electrical shock. WARNING Use the proper fuse. Fuse rating is shown on the equipment. Use of a wrong fuse can result in damage to the equipment. 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 on the top of 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. iii WARNINGWARNING 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 land- mass, 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. 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 t o 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. iv WARNING To avoid electrical shock, do not remove cover. No user-serviceable parts inside. 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. WARNINGARNING Radiation hazard. Only qualified personnel should work inside scanner. Confirm that TX has stopped before opening scanner.

Type: Choose type of this radar among 8062 (6 kW radar), 8122 (12 kW radar) and 8252 (25 kW radar) to coincide with the specifications of the antenna unit. The default setting is 8062. Unsuitable setting may result malfunctions. 3. SETTING UP THE EQUIPMENT 3-2 View Position: Choose an operating position for this radar among Left, Left-Center, Center, Right-Center and Right to view the colors (echo, background, characters, etc.) correctly. The default setting is Center. Left: When operating this radar at the left side. Left-Center: When operating this radar at the left-center side. Center: When operating this radar at center position. Right-Center: When operating this radar at the right-center side. Right: When operating this radar at the right side. Input Source: Choose the input source between Main and Sub. The default setting is Main. Main: When using this display unit as main radar. Sub: When using this display unit as sub display. Antenna Height: Choose a position of the antenna unit from the sea level among 5, 10, 15, 20, 30, 40 and 50 m. The default setting is 5 m. Local Time Offset: To display a local time on the screen, set the time difference from the UTC. Heading Adjustment You have mounted the antenna unit facing straight ahead in the direction of the bow. Therefore, a small but conspicuous target dead ahead visually should appear on the heading line (zero degrees). In practice, you will probably observe some small error on the display because of the difficulty in achieving accurate initial positioning of the antenna unit. The following adjustment will compensate for this error. 1. Set ship’s heading toward a suitable target (for example, ship or buoy) at a range between 0.125 and 0.25 nautical mile. 2. Transmit the radar at 0.25 nm range and measure the bearing of that target relative to ship’ heading with EBL. 3. Open the Installation menu, and choose Heading Adjust. 4. Press the ENTER key to show the HEADING ADJUST window. S S 0 ° (0 ° ∼ 359 °) 5. Rotate the trackball upward or downward to set the value measured at the step 2 above. 6. Press the ENTER and confirm that the target shows dead ahead on the screen. 3-3 Auto Installation Setup When this item is executed, the tune adjustment, timing adjustment, video adjustment and MSB adjustment are automatically done. 1. Transmit the radar at 48 nm range. 2. Choose Auto Installation Setup at the installation menu and press the ENTER key. 3. Rotate the trackball to choose Yes, and then press the Enter key. Automatically, the tune adjustment begins, indicating “Tuning adjusting....” Then, the timing adjustment, video adjustment and MSB adjustment are execute automatically, indicating “Timing adjustment...”, “Video adjustment...”, and “MSB adjustment...” in that order. After adjustment, the window disappears. If you do not satisfy the result of the Auto Installation Setup, execute Manual Timing Adjust, Tuning Initial Adjust and Manual MSB Adjust as follows. Tuning Initial Adjust 1. Transmit the radar. 2. Open the Installation menu, and choose Tuning Initial Adjust. 3. Press the ENTER key to show the setting window. 4. Rotate the trackball to choose Yes, and then press the Enter key. The tune adjustment begins, indicating “Tuning adjusting....” After adjustment, the window disappears. Manual Timing Adjust This adjustment ensures proper radar performance, especially on short ranges. The radar measures the time required for a transmitted echo to travel to the target and return to the source. The received echo appears on the display based on this time. Thus, at the instant the transmitter is fired, the sweep should start from the center of the display (sometimes called sweep origin.) A trigger pulse generated in the display unit goes to the antenna unit through the signal cable to trigger the transmitter (magnetron). The time taken by the signal to travel up to the antenna unit varies, depending largely on the length of signal cable. During this period the display unit should wait before starting the sweep. When the display unit is not adjusted correctly, the echoes from a straight local object (for example, a harbor wall or straight pier) will not appear with straight edges – namely, they will be seen as “pushed out” or “pulled in” near the picture center. The range of objects will also be incorrectly shown. (1) Target pulled (2) Correct (3) Target pushed outward…
