MARINE RADAR
FR-8062, FR-8122, FR-8252
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 W/m2 and 10 W/m2 exist are given in the table below.
Note: If the antenna unit is installed at a close distance in front of the wheel house, it may be necessary to prevent transmission in that area to protect passengers and crew from microwave radiation. This can be done with Sector Blank in the System menu.

SAFETY INSTRUCTIONS
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 warning 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 equipment 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.
ii
WARNING
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.
•The 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 ARP 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 landmass, 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.
SAFETY INSTRUCTIONS
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 to 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 and AIS are intended for reference purposes only.
Check all available navigation aids to determine target moviement.

SAFETY INSTRUCTIONS
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
To avoid electrical shock, do not remove cover. No user-serviceable parts inside.
WARNING
Radiation hazard. Only qualified personnel should work inside scanner. Confirm that TX has stopped before opening scanner.

1. OPERATIONAL OVERVIEW
Press the POWER/BRILL key at the top of the control panel to turn the radar on, and the lamp to its left lights. To turn the radar off, press and hold down the key until the screen turns black.
At power-up, the start-up screen appears, showing the model name, program number and the results of the ROM and RAM check, OK or NG (No Good). If an NG appears, try pressing any key other than the power key to proceed. If normal operation is not possible, contact your dealer for advice.

Start-up screen
After the tests are completed, the bearing scale and a digital timer appear. The digital timer counts down the time remaining to warm up the magnetron, which transmits the radar pulses. This warmup takes 180 sec. (FR-8252) or 90 sec. (FR-8062, FR-8122).
After the timer has counted down to 0:00, the STBY screen appears, the appearance of which you may choose according to your needs. (For further details, see paragraph 1.41.2.) The radar is now ready to transmit radar pulses. Press the STBY/TX key to transmit radar pulses.
The STBY/TX key toggles between stand-by and transmit status. The antenna rotates in transmit condition and is stopped in standby. Because the magnetron ages with use it is highly recommended to set the radar in standby when it will not be required for an extended period of time, to extend the life of the magnetron.
Quick start
Provided that the radar was once in use with the transmitter tube (magnetron) still warm, you can get the radar into TRANSMIT condition without the warm-up. If the POWER/BRILL key was turned off by mistake or the like and you wish to restart the radar promptly, turn on the POWER/ BRILL key not later than 10 seconds after power-off. This feature is not available with the
FR-8252.

1. OPERATIONAL OVERVIEW
This radar has the following presentation modes:
Relative Motion (RM)
Head-up: Unstabilized display. Heading is at the top of the screen.
Course-up: Compass-stabilized relative to ship's orientation. The bearing scale rotates to place ship’s heading (course set) at the screen top at the moment the course-up mode is selected.
North-up: Compass-stabilized with reference to north. Bearing scale is fixed.
True Motion (TM)
North-up: Ground or sea stabilized with compass and speed inputs. Own ship moves on the display. Landmasses and sea are fixed.
1.7.1Choosing presentation mode
Press the MODE key consecutively to choose presentation mode desired. The presentation mode in use appears at the top left corner on the screen.
All modes except head-up require a heading signal, in AD-10 format or NMEA Note format. If the heading signal is lost, the mode is changed to head-up and the north
marker disappears. Further, the heading readout shows XXX.X and the message “GYRO” (AD-10 format data) or “NMEA-HEAD” (NMEA format data) appears in the alarm message display. Restore gyro input and confirm bearing.

1. OPERATIONAL OVERVIEW |
Course-up mode |
Heading Line |
North Marker |
The course-up mode is 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. The heading line moves in accordance with ship's yawing and course change. This mode is useful to avoid smearing of picture during course change.
North-up mode
The north-up mode paints target pips at their measured distances and in their true (heading sensor) directions from own ship, north bearing maintained at the top of the screen. The heading line changes its direction according to the ship's heading.
True motion mode
Own ship and other moving objects move in accordance with their true courses and speed. In ground stabilized TM, all fixed targets, such as landmasses, appear as stationary echoes.
When own ship reaches a point corresponding to 75% of the radius of the display, own ship position is automatically reset to a point of 75% radius opposite to the extension of the heading line passing through the display center. You may also reset the own ship symbol manually by pressing the OFF CENTER key. The method of resetting is the same as mentioned above.

1.Push the A/C SEA control to show “SEA MAN” as the A/C SEA adjustment method.
2.Rotate the A/C SEA control to suppress sea clutter.
The proper setting of the A/C SEA control is such that the clutter is broken up into small dots, and small targets become distinguishable. If the setting is set too low, targets will be hidden in the clutter, while if the setting is too high, both sea clutter and targets will disappear from the display. In most cases adjust the control until clutter has disappeared to leeward, but a little is still visible windward.

Appearance of sea clutter
The vertical beamwidth of the antenna is designed to see surface targets even when the ship is rolling. However, by this design the unit will also detect rain clutter (rain, snow, or hail) in the same manner as normal targets.
The A/C RAIN control adjusts the receiver sensitivity as the A/C SEA control does but rather in a longer time period (longer range). The higher the setting the greater the anti-clutter effect. When echoes from precipitation mask solid targets, adjust the control to split up these unwanted echoes into a speckled pattern, making recognition of solid targets easier.
1.12.1Choosing rain clutter adjustment method
Rain clutter may be adjusted automatically or manually. Push the A/C RAIN control to choose automatic or manual adjustment alternately. The adjustment method currently chosen is show at the top right corner of the screen. In the example below the rain clutter adjustment method is “AUTO.”

Mutual radar interference may occur in the vicinity of another shipborne radar operating in the same frequency band (9 GHz). It is seen on the screen as a number of bright spikes either in irregular patterns or in the form of usually curved spoke-like dotted lines extending from the center to the edge of the picture. Activating the interference rejector circuit can reduce this type of interference.

1. OPERATIONAL OVERVIEW
The range to a target may be measured three ways: with the fixed range rings, with the cursor (if set to measure range and bearing), and with the VRM.
Use the fixed range rings to obtain a rough estimate of the range to a target. They are the concentric solid circles about own ship, or the sweep origin. The number of rings is automatically determined by the selected range scale and their interval is displayed at the upper-left position of the screen. Count the number of rings between the center of the display and the target. Check the range ring interval and judge the distance of the echo from the inner edge of the nearest ring.

1.16.2Measuring range by the variable range marker (VRM)
There are two VRMs, No. 1 and No. 2, which appear as dashed rings so that you can discriminate them from the fixed range rings. The two VRMs can be distinguished from each other by different lengths of dashes.
1.Press the VRM key to display either of the VRMs. Successively pressing the VRM key toggles the active VRM between No. 1 and No. 2. The currently active marker is enclosed with >.....< in the VRM indication box.
2.Operate the Trackball to align the variable range marker with the inner edge of the target of interest and read its distance at the lower-right corner of the screen. Each VRM remains at the same geographical distance when you operate the RANGE key. This means that the apparent radius of the VRM ring changes in proportion to the selected range scale.
3.You may “anchor” the VRM by choosing it and pressing the ENTER key.
4.To erase a VRM, make it active and press the CANCEL/HL OFF key.
