SAFETY INSTRUCTIONS

WARNINGRadio Frequency Radiation Hazard

The radar antenna emits electromagneticradio frequency (RF) energy which can beharmful, particularly to your eyes. Neverlook directly into the antenna aperture froma close distance while the radar is in oper-ation or expose yourself to the transmittingantenna at a close distance.

Distances at which RF radiation levels of100 and 10 W/m2 exist are given in the tablebelow.

Note: If the antenna unit is installed at aclose distance in front of the wheel house,your administration may require halt oftransmission within a certain sector ofantenna revolution. This is possible—Askyour FURUNO representative or dealer toprovide this feature.

1.1 Mounting Considerations for Radar Antenna

• The antenna unit is generally installed ei-ther on top of the wheelhouse or on theradar mast on a suitable platform. Locatethe antenna unit where there is a good all-round view rigging intercepting the scan-ning beam. Any obstruction will causeshadow and blind sectors. A mast for in-stance, with a diameter considerably lessthan the width of the radiator, will causeonly a small blind sector, but a horizontalspreader or crosstrees in the same hori-zontal plane as the antenna unit would bea much more serious obstruction; youwould need to place the antenna unit wellabove or below it.

• It is rarely possible to place the antennaunit where a completely clear view in alldirection is available. Thus, you should de-termine the angular width and relativebearing of any shadow sectors for theirinfluence on the radar at the first opportu-nity after fitting.

• If there is a radio direction finder on theship, locate its antenna clear of the an-tenna unit, to prevent interference to thedirection finder. A separation of more thantwo meters is recommended.

• To lessen the chance of picking up elec-trical interference, avoid where possiblerouting the signal cable near other onboardelectrical equipment. Also avoid runningthe cable in parallel with power cables.

MOUNTING AND WIRING OFRADAR ANTENNA, GPS ANTENNA

• A magnetic compass will be affected ifplaced to close to the antenna unit. Ob-serve the compass safe distances belowto prevent deviation of the magnetic com-pass: Standard compass, 1.10, Steeringcompass 0.75 m.

• Do not paint the radome (Model FRS-1000A) or radiator aperture (FRS-1000B/FRS-1000C), to ensure proper emissionof the radar waves.

• The signal cable run between the antennaand the display comes in lengths of 10 m,15 m, 20 m and 30 m. Whatever length isused it must be unbroken; namely, nosplicing allowed.

• Deposits and fumes from a funnel or otherexhaust vent can adversely affect theaerial performance and hot gases may dis-tort the radiator portion. The antenna unitmust not be mounted where the tempera-ture is more than 70°C.

The mounting surface must be parallel withthe waterline and provided with five holeswhose dimensions are shown in the outlinedrawing attached at the end of this manual.

The unit is adjusted so a target echo returnedfrom the bow direction will be shown on thezero degree (heading line) position on thescreen. When drilling holes, be sure they areparallel with the fore and aft line.

3. Prepare a platform of 5 to 10 millimetersin thickness for the antenna unit. A mount-ing bracket for mounting the antenna uniton a sailboat mast is optionally available.(Refer to page 1-9.) Find the cable entryon the radome base. Next, position theradome base so the cable entry faces thestern direction. This alignment must beas accurate as possible.

1.4 GPS Antenna

Mounting considerations

• Install the antenna unit referring to the in-stallation diagram on page D-3, D-4. Whenselecting a mounting location for the an-tenna unit, keep in mind the followingpoints.

• Select a location out of the radar beam.The radar beam will obstruct or preventreception of the GPS satellite signal.

• Be sure the location offers a clean line-of-sight to satellite. Objects within line-of-sight to a satellite, for example, a mast orfunnel, block reception and cause pro-longed acquiring time or interruption ofposition fix.

• Mount the unit as high as possible. Mount-ing the antenna as high as possible keepsit free of water spray, which can interceptreception of GPS satellite signal, if waterspray is frozen.

1-9

• A beacon antenna is required for use withthe antenna GPA-018S. Use a 1.2 m whipantenna. Do not use a 2.5 m whip antenna;the antenna chassis may be damaged.

• For the GPA-018 and GPA-018S, groundthem with a ground wire of IV-1.25 sq (lo-cal supply).

Extending antenna cable length

The standard cable is 15 m long. 30 m and50 m long extension cable sets are option-ally available.

DISPLAY UNIT, PROCESSOR UNIT

2.1 Display Unit

The display unit can be mounted on a table-top (in a hanger) or in a panel. When select-ing a mounting location, keep in mind thefollowing points:

• Select a location where the display unitcan be viewed and operated convenientlyand where the screen can be viewed whilefacing towards the bow.

• Locate the unit out of direct sunlight andway from heat sources because of heatthat can build up inside the cabinet.

• Locate the equipment away from placessubject to water splash and rain.

• Be sure the mounting location is strongenough to support the weight of the unitunder the continued vibration which isnormally experienced on the ship. If nec-essary reinforce the mounting location.

• Determine the mounting location consid-ering the length of the signal cable be-tween the scanner unit and the displayunit.

• Leave sufficient space on the sides andrear of the unit to facilitate maintenance.Also, leave a foot or so of “service loop” incables behind the unit so it can be pulledforward for servicing or easy removal ofconnectors.

• A magnetic compass will be affected ifplaced too close to the display unit. Ob-serve the following compass safe dis-tances to prevent deviation of a magneticcompass: Standard compass, 1.10 m,Steering compass, 0.8 m.

• The sub-display unit is installed similar tothe main display unit. The total length ofcables between the processor unit, displayunit and sub-display unit(s) shall not ex-ceed 30 m. Performance cannot be guar-anteed if this length is exceeded.

• If the mounting location is subject to heavyvibration, fix the display unit to the hangerperpendicular.

3.1 Thru-hull Mount Transducer 520-5PSD, 520-5MSD

Transducer mounting location

This type of mounting provides the best per-formance of all, since the transducer pro-trudes from the hull and the effect of airbubbles and turbulence near the hull skin isreduced. When the boat has a keel, the trans-ducer should be at least 30 cm away from it.Typical thru-hull mountings are shown in Fig-ure 3-4.

The performance of this sounder is directlyrelated to the mounting location of the trans-ducer, especially for high-speed cruising. Theinstallation should be planned in advance,keeping the cable length and the followingfactors in mind:

• Air bubbles and turbulence caused bymovement of the boat seriously degradethe sounding capability of the transducer.The transducer should, therefore, be lo-cated in a position where water flow is thesmoothest. Noise from the propellers alsoadversely affects performance and thetransducer should not be mounted nearby.The lifting strakes are notorious for creat-ing acoustic noise, and these must beavoided by keeping the transducer inboardof them.

• The transducer must always remain sub-merged, even when the boat is rolling,pitching or up on a plane at high speed.

• A practical choice would be somewherebetween 1/3 and 1/2 of the boat’s lengthfrom the stern. For planing hulls, a practi-cal location is generally rather far astern,so that the transducer is always in waterregardless of the planing attitude.

channel to divert turbulent water aroundthe sides of the transducer rather thanover its face.

Figure 3-5 Construction of fairing block

3. Drill a hole just large enough to pass thethreaded stuffing tube of the transducerthrough the hull, making sure it is drilledvertically.

4. Apply a sufficient amount of high qualitycaulking compound to the top surface ofthe transducer, around the threads of thestuffing tube and inside the mounting hole(and fairing blocks if used) to ensure wa-tertight mounting.

5. Mount the transducer and fairing blocksand tighten the locking nuts. Be sure thatthe transducer is properly oriented and itsworking face is parallel to the waterline.

Note: Do not over-stress the stuffing tube andlocking nuts through excessive tightening,since the wood block will swell when the boatis placed in the water. It is suggested thatthe nut be tightened lightly at installation andretightened several days after the boat hasbeen launched.

Procedure for installing the thru-hull mount transducer

1. With the boat hauled out of the water,mark the location selected for mountingthe transducer on the bottom of the hull.

2. If the hull is not level within 15° in anydirection, fairing blocks made out of teakshould be used between the transducerand hull, both inside and outside, to keepthe transducer face parallel with the wa-ter line. Fabricate the fairing block asshown below and make the entire surfaceas smooth as possible to provide an un-disturbed flow of water around the trans-ducer. The fairing block should be smallerthan the transducer itself to provide a

3.2 Transom Mount Transducer 520-5PWD, Optional Transom Mount Triducer 520ST-PWD

This type of mounting is very commonly em-ployed, usually on relatively small I/O or out-board boats. Do not use this method on aninboard motor boat because turbulence iscreated by the propeller ahead of the trans-ducer.

There are two methods of installation: flushwith hull (for flat hulls) and projecting fromhull (for deep V-hulls).

Figure 3-6 Transom mount transducermounting locations

Installing the transom mounttransducer flush with hull (for flathulls)

A suitable mounting location is at least 50cm away from the engine and where thewater flow is smooth.

1. Drill four pilot holes in the mounting loca-tion.

2. Attach the transducer to the bracket withtapping screws (supplied).

3. Adjust the transducer position so thetransducer faces right to the seabed.

Note: If necessary, to improve water flowand minimize air bubbles staying on thetransducer face, incline the transducerabout 5° at the rear. This may require acertain amount of experimentation for finetuning at high cruising speeds.

4. Fill the gap between the wedge front ofthe transducer and transom with epoxymaterial to eliminate any air spaces.

Figure 3-7 Transom mount transducer,mounting flush with hull

Installing the transom mounttransducer projecting from hull (fordeep-V hulls)

This method is employed on deep-V hulls andprovides good performance because the ef-fects of air bubbles are minimal. Install thetransducer parallel with water surface; notflush with hull. If the boat is placed on a trailercare must be taken not to damage the trans-ducer when the boat is hauled out of the waterand put on the trailer.

Figure 3-8 Transom mount transducer,projecting from hull

Transducer preparation

Before putting the boat in water, wipe the faceof the transducer thoroughly with a detergentliquid soap. This will lessen the time neces-sary for the transducer to have good contactwith the water. Otherwise the time requiredfor complete “saturation” will be lengthenedand performance will be reduced.

Do not paint the transducer. Performance willbe affected.

Attaching the transducer

1. Clean the transducer face to remove anyforeign material. Lightly roughen thetransducer face with #100 sandpaper.Also, roughen the inside of the hull wherethe transducer is to be mounted.

2. Warm the silicone sealant to 40°C beforeusage to soften it. Coat the transducerface and mounting location with siliconesealant.

Necessary tools

You will need the following tools:

• Sandpaper (#100)• Silicone sealant• Silicone grease

Remarks on installation

• Turn off the engine and anchor the boatwhile installing the equipment.

• Install the transducer in the engine room.

Selecting the mounting location

Keep the following points in mind when se-lecting a mounting location:

• The mounting location should be wherethe hull is of single-hull thickness and isvoid of air or flotation materials other thansolid fiberglass between the transducerface and the water.

• Do not place the transducer over hull strutsor ribs which run under the hull.

• Avoid a location where the rising angle ofthe hull exceeds 15°, to minimize the ef-fect of the boat’s rolling.

• You will finalize the mounting locationthrough some trial and error. The proce-dure for this is shown later.

5.2 Tuning Adjustment

1. Select TUNE ADJUSTMENT from page1 of the installation menu.

2. Press the [ENT] key.

5.3 Adjusting Sweep Timing

This adjustment ensures proper radar per-formance, especially on short ranges. Theradar measures the time required for a trans-mitted echo to travel to the target and returnto the source. The received echo appears onthe display based on this time. Thus, at theinstant the transmitter is fired, the sweepshould start from the center of the display(sometimes called sweep origin).

A trigger pulse generated in the display unitgoes to the antenna unit (via the processorunit) through the signal cable to trigger thetransmitter (magnetron). The time taken bythe signal to travel up to the antenna unitvaries, depending largely on the length of thesignal cable. During this period the displayunit should wait before starting the sweep.When the display unit is not adjusted cor-rectly, the echoes from a straight local object(for example, a harbor wall or straight pier)will not appear with straight edges – they willbe seen as “pushed out” or “pulled in” nearthe picture center. The range of objects willalso be incorrectly shown.

5.6 Adjusting MBS (Main Bang Suppression)

Main bang, a large filled circle which appearsat the display center on short ranges, can besuppressed as follows:

1. Transmit on long range and wait 10 min-utes.

2. Adjust gain so a slight amount of noise ispresent on the screen.

3. Transmit on the 0.125 nautical mile range.Adjust the A/C SEA for proper picture.(Keying sequence: [RDR MENU], [4], useomnipad to adjust, and press the [ENT]key.)

4. Select MBS ADJUSTMENT from page 1of the installation menus.

5. Using the omnipad, set suitable value (00-25) to suppress main bang.

6. Press the [ENT] key.

7. Confirm that main bang is suppressed. Ifnot, repeat steps 4-6.

2. Visually select a target which forms astraight line (for example, harbor wall,straight pier).

3. Select SWEEP TIMING ADJ from page 1of the installation menus.

4. Using the omnipad, set suitable value(00.0 nm to 99.9 nm, default setting forFRS-1000B/FRS-1000C: 0.068) tostraighten target.

5.13 Adjustment of Terminator B

This equipment may have a new type of ter-minator B. The new type may be adjusted;the former type could not. When the lengthof the video cable is more than 15 meters, orthe length is less than 15 meters and threedisplay units are connected, the terminatorshould be adjusted since the length of thevideo cable affects the video sounder picture.

The terminator B can be seen on the circuitboard which is visible from the hole for theconnection cable. If the terminator B is blueit is the former type.

If the new type terminator B is required, or-der it as follows: Type: OP86-10, Code No.:006-969-140.

Normally, no adjustment of the terminator Bis necessary. However, if a black tail ispainted on the video sounder picture, adjustthe terminator as follows:

1. Unfasten the terminator housing.

2. Unplug the video cable (DSUB connec-tor) connected to the last sub-display unitand connect it to the VO terminal.

3. Attach the terminator B to the VI termi-nal. (The parts side is up. There are threepotentiometers on the circuit board, andtheir colors are from left, red, green, blue.)

4. Using a slotted-head screwdriver, adjustthe blue potentiometer such that the blacktail just disappears. (Normally it is notnecessary to rotate the potentiometermore than ±90°. However, no abnormalcondition will result if it is rotated morethan this value. Insert the blade of thescrewdriver at an angle to adjust.)

5. Turn off the power. Refasten the housingto the terminator and attach it to the VOterminal. (As long as the terminator isproperly adjusted, the video cable may beattached to the VI or VO terminal.)

Note: Be sure to attach the waterproofingcap.

Unfasten housing.
