To set a tilt angle, operate the TILT control. Watch the tilt angle indication at the top right corner of the screen. The tilt angle can be set in one-degree steps from +5° (upward) to 90° (downward).

2.5.1 Tilt angle for surface fish

Sound emitted from the sonar transducer forms an oval-shaped beam with a width of approximately 11° (for 113 kHz transducer) in the vertical direction (vertical beam width). The tilt angle is indicated by the angle between the center line of the beam and the horizontal plane. Then, if the tilt angle is set to 0°, the center line is parallel with the sea surface and one half of the emitted sound goes upward, toward the sea surface.

This causes one half of the emitted sound to be reflected toward the transducer and displayed on the screen as sea surface reflections. When the sea is calm, since the sound is reflected just like a light hitting a mirror at a narrow incident angle, it propagates away and the sea surface reflections become negligible

However if the sea is not calm enough, they will become dominant and interfere with observation of wanted echoes. To minimize these sea surface reflections and to search surface schools of fish effectively, the tilt angle is usually set between 5° and 7° so the upper portion of the beam becomes almost parallel with the sea surface. When the sea is rough, it is often set to a little larger angle.

2.5.2 How to discriminate fish echoes from the bottom

Finding a proper tilt angle is important when searching for fish.

Following figure illustrates how schools of fish are displayed on the screen using three different tilt angles.

Point to consider

• Normally, a vertically distributed schools of fish are better sonar target than the bottom, because it reflect the transmitted pulse back toward the transducer.

• In case of 3, both schools of fish (a) and (b) are presented. However midwater schools of fish tend to be larger than bottom schools of fish and they are often displayed near the bottom on the display.

• It is difficult to detect bottom fish when they are not distributed vertically.

2.5.3 Suitable tilt angle

The figure below illustrates the relationship among tilt angle, depth and detection range. Refer to it to find out the suitable tilt angle for a given depth/detection range.

2.7.1 Relocating a school of fish for easy observation

When a school of fish is near the edge of the screen and inconvenient for observation, use the expanded sonar mode and adjust the TRAIN control (off-center function) to relocate the school of fish close to the screen center.

2. SONAR MODE

2.7.2 Suppressing bottom and sea surface reflections

In shallow fishing grounds, excessive sea surface and bottom reflections often interfere with wanted fish echoes and they cannot be eliminated sufficiently with the aforementioned TVG controls. In such cases, try to reduce the output power from C to B or A on the SONAR menu, without turning down the gain. The picture becomes clearer when output power is reduced rather than when the gain is decreased, as illustrated below.

2.7.3 Suppressing bottom tail

As described earlier, schools of fish near the bottom are sometimes difficult to detect because you have to discriminate fish echoes from the bottom reflections. To discriminate fish echoes near the bottom, select the short Tx pulse length on the SONAR menu to decrease the tail of bottom reflection.

2.7.4 Displaying surface fish clearly (TVG adjustment)

Echoes from targets (such as the bottom or a fish) return to the transducer in order of the distance to them, and when their intensities are compared at the transducer face, those from nearer targets are generally stronger when their reflecting properties are

nearly equal. The sonar operator will be quite inconvenienced if these echoes are directly displayed on the screen, since he won’t be able to judge the actual size of the target from the size of echoes displayed on the screen. To overcome this inconvenience, use the TVG function. It compensates for propagation loss of sound in water: amplification of echoes on short range is suppressed and gradually increased as range increases so that similar targets are displayed in similar intensities irrespective of the ranges to them.

The TVG LEVEL and TIME controls compensate for propagation loss. The effective distance is up to 1000 m approximately.

The TVG also functions to suppress unwanted echoes and noise which appear in a certain range area on the screen as shown in the figure above.

1) Set TVG time between 3 and 5. (130 to 300 m approx.) This is the standard setting and you can maintain it in most cases.

2) When sea surface reflections or plankton layers disturb the picture, set the TVG level control around 5 to eliminate them.

3) Locate a school of fish on a long range setting which is approaching your vessel. Adjust the tilt to keep the school of fish in the center of the sonar beam. Check that the fish echo appears in the same color while it approaches. If the color changes suddenly to weaker colors as the fish echo nears, the TVG is improperly set. Adjust the TVG level to correct it. If sea surface reflections and noise remain, try to remove them with the interference rejector (“IR” on the SONAR menu) and NL control as described on section 2-8.

2.7.5 Detecting schools of fish aurally

Occasionally you will be preoccupied with other tasks and unable to concentrate on watching the sonar picture. In such cases it would be a good choice to use the audio function. This function enables you to monitor echoes from schools of fish and bottom through the external speaker (option), of which the volume can be adjusted with the AUDIO control on the sub panel 1.

SUB PANEL 1

E NL AUDIO

AUDIO

(Turn clockwise to get high volume)

After you become accustomed to utilizing the audio function, you should be able to detect a school of fish from a range longer than you can detect it on the screen. In addition you may judge whether the schools of fish is approaching or going away; the tone becomes higher when the fish is approaching and lower when going away.

2.8 Rejecting Sonar Interference and Noise

While observing the sonar picture, you may encounter occasional or intermittent noise and interference as shown below. These are mostly caused by onboard electronic equipment, engine, propeller noise, or electrical noise from other sonars being operated nearby.

Identifying noise source

To eliminate noise effectively, you should first identify the source of noise as follows:

• Operate all onboard equipment one by one while observing the picture.

• Run the boat at various speeds to check if the noise is speed dependent.

If neither of the above affects the picture, turn on “IR“ in the SONAR menu or adjust NL control as below.

Rejecting noise with the interference rejector

This control is effective in rejecting random noise and sea surface reflections in rough sea conditions. Pull the GAIN control and adjust it to eliminate only noise. Reject the noise with “IR” in the SONAR menu. Do not use an unnecessarily high setting since it many also reject small wanted echoes.

2. SONAR MODE

Rejecting noise with NL control

Weak, unwanted reflections, colored light blue or green, appear when water is contaminated, or plankton layers or noise exist. These echoes gradually become bluish as the NL control is turned clockwise. Usually a setting from 3 to 4 provides sufficient reduction.

Rejecting interference with Tx rate

When other sonars are operating nearby at the same transmission interval as that of own ship’s sonar, interference caused by other sonars appears. To reduce the interference, reduce the Tx rate setting on the SONAR menu.

Note: When the sonar is used in shallow water with the range set between 100 m and 200 m and the Tx rate at 10, bottom reflections caused by the transmission which is the last but one appear on near on screen. Reduce the Tx rate to 7 or 8 to reject them.

2.9.2 Bottom echoes

When the tilt angle is widened, the bottom echo illustrated below will appear on the display. When the tilt is narrowed, the bottom trace becomes wider and weaker. By observing the bottom condition on the display, the skipper can prevent net damage.

2.9.5 Wake

A wake produced by own ship or another ship can be a strong reflecting object when a narrow tilt angle is used. As the wake appears as a thick continuous line, it can be easily distinguished from a school of fish. A wake contains many air bubbles which attenuate ultrasonic energy, making it difficult to sound beyond the wake.

2.9.6 False echo by sidelobe

An ultrasonic wave is emitted only in the direction set by the TILT control, however there are some emissions outside the main beam. These are called sidelobes. The energy of the sidelobe is fairly weak but when the water is comparatively shallow and the bottom is rocky and hard, strong signals are detected by the sidelobe. These are represented on the display as a false echo as shown below.

The bottom echo detected by sidelobe appears at a certain tilt angle when the sidelobe points vertically. Also, poor soundome projection may result in a similar false echo.

2.9.7 Noise and interference

When the fishing ground is crowded with many fishing boats, the sonar is subject to interference from ultrasonic equipment (echo sounder or sonar) on other boats as well as those on own ship. For instance, interference from the sonar operated on other boats will show itself on the display as in (a).

2-12

This interference can be suppressed by changing the Tx rate on the SONAR menu. Noise from marine life shows itself on the displays as in (b). This type of noise can be suppressed with “IR” in the SONAR menu.

Menu Description

TVG (LEVEL) Controls the receiver sensitivity in short to medium ranges

to eliminate surface noise, which may mask shallow targets.

TVG (TIME) Determines the TVG effective depth.

BEAM WIDTH Sets the vertical beam width is useful for searching a wide

area vertically but fish detection range is shortened since the transmitted power attenuates.

AUTO TRAIN SECTOR Sets the train sector, 90°, 180°, 360°. Use a wide sector to

conduct a general search, narrowing it once a school of fish is detected.

VERT. ECHO OVERLAY Turns on/off the vertical echoes.

3D VIEW SCALE Determines the depth item, time or distance for 3D display

mode. (Requires optional equipment)

TIME (DIST) SCALE Selects z-axis scale of 3D picture.

4.3 Changing 3D View Scale Mode and Selection

The depth (z-axis) of the graph is displayed in either “TIMe” or “DISTance” scale mode. The depth can be set to 500 or 1000 meters in the distance scale mode, or 1/ 1, 1/2 or 1/4 in the time scale mode. The fraction means graph update/number of transmission. “1/4” for example, means the graph is updated every four transmissions.

These selections are made on the 3D VIEW SCALE and TIME SCALE (or DISTANCE SCALE) lines of the BOTTOM/3D menu.

The time mode should be selected when speed data is not being fed to the unit from navaids or speed log.

8. MAINTENANCE

WARNING

ELECTRICAL SHOCK HAZARD Do not open the equipment.

This equipment uses high voltage that can cause electrical shock. Only qualified personnel should work inside the equipment.

NOTICE

Do not apply paint, anti-corrosive sealant or contact spray to plastic part or equipment coating.

Those items contain products that can damage plastic parts and equipment coating.

WARNING

Good performance depends on regular maintenance. Following the recommended procedures in this chapter will keep the equipment operating in top condition for years to come.

8.1 General Maintenance

• Handle with care. Corrosion may start even from a scratch.

• Allow space around the unit for ventilation.

• Keep the equipment away from magnets (such as a speaker, large capacity trans-

former) and also magnetic sensitive units like a gyrocompass.

• Clean the filter and screen with a wet or dry soft cloth. Do not use commercial clean-

ers or solvents to clean the unit. They may remove paint and markings.

8.2 Maintenance of Transceiver Unit

Keep the unit clean, especially the cable entrance. Wipe off dust or oil with a cloth dampened in water-diluted mild detergent.

8.3 Fuse Replacement

WARNIN

Use the proper fuse.

Fuse rating is shown on the equipment. Use of a wrong fuse can result in equipment damage.

The fuses in the processor and transceiver units protect them from overvoltage, equipment fault and reverse polarity of the ship’s mains. If the power cannot be applied, first check the fuse for the processor unit. The fuse for the transceiver unit is inside the unit; have a qualified technician check the fuse. If a fuse blows after replacement, or the power cannot be turned in spite of normal fuse, contact your dealer for advice.

8.9 Troubleshooting

The table below provides common symptoms of equipment troubles and the means to rectify them. If normal operation cannot be restored, do not check inside the system. Any repair work is best left to a qualified technician.

Symptom Check

No picture Power supply.

Check ship’s mains voltage at the power plug connected to the power unit. Fuse. If blown, replace with 3A fuse. Call service technician if it blows again. NEVER use a fuse of a higher rating.

Bottom echo becomes irregular

Weak echo TX OUTPUT POWER set to other than “C“.

Somewhat strange color BRILL control set too low.

Rough seas. Distance to sea bottom changes due to rolling and pitching. Long range selected. Since transmission period is a little longer, ship’s rolling and pitching are apt to effect detection of echo.

Check the TX output power setting on the sonar menu, and set it to “C” for max. output power. TVG effect is excessive. Excessive TVG results in elimination of useful echoes. Note: Readjustment of TVG is required whenever the GAIN control is suggested.

Increase the brightness.

Color partially irregular Magnet is near the screen.

This symptom occurs if equipment which contains a magnet (loudspeaker, etc.) is placed near the screen. Separate the magnetic equipment from the unit. Note: If the symptom continues, consult with electronics technician.

8. MAINTENANCE

Symptom Check

Picture distorted Equipment generating strong magnetic field is near display

unit. Locate magnetic field generating equipment (rectifier, etc.) well away from the display unit.

Picture contains noise Equipment not grounded properly. Carefully check the

ground. Power cable is run alongside the signal cable. Signal cable may pickup noise emitted from power cable of other equipment; therefore, separate them from each other. Debris may be on sea surface. Reject unwanted echoes with the interference rejector on the SONAR menu, TVG control or NL control.

Trail speed is low Confirm if the “IR“ is ON in the SONAR menu.

If the “IR“ function is ON, trail is lower than usual cause the reflection signal is compared with latest. Use the function ’off’ in usual.
