Page 30 1. OPERATIONAL OVERVIEW Tilt Angle The tilt angle shows the angle from the sea surface at which the sound wave is emit- ted. When the sound wave is emitted horizontally, it is said to be zero (0) degrees, and when emitted vertically, 90 degrees. 1.4.1 How to set the tilt angle To manually set the tilt angle, operate the TILT lever.
Page 31 1. OPERATIONAL OVERVIEW 3) Select [Auto Tilt Lower End]. 4) Set the lower angle from -5° to 60°. 7. Adjust the automatic tilt settings if necessary as follows. 1) Select [Auto Tilt Angle]. 2) See the following table and set the auto tilt angle from 1° to 5°. 3) Select [Auto Tilt TX Count].
Page 32 1. OPERATIONAL OVERVIEW 1.4.3 How to distinguish fish echoes from the bottom Finding the proper tilt angle is of utmost importance when searching for fish, especially in coastal water fishing, where the depth of the fishing ground is from 50 to 100 m. In this type of fishing ground, it is imperative that the bottom echo be always displayed to properly distinguish between fish and the bottom.
Page 33 1. OPERATIONAL OVERVIEW 1.4.4 Tilt angle for surface fish An ultrasonic wave emitted from the sonar transducer forms an oval-shaped beam with a width of approximately 6° in the vertical direction (vertical beam width at -3 dB). The tilt angle indicates the angle between the centerline of the beam and the horizon- tal plane.
Page 34 1. OPERATIONAL OVERVIEW Range and Bearing to a Target Operate the trackball to place the cross-hair cursor (trackball mark) on the target you want to measure the range and bearing. The range from the own ship position, bear- ing, and depth to the target appear at the upper left corner of the sonar display. The latitude and longitude of the cross-hair cursor position are also displayed on the bot- tom of the display.
Page 35 FINE TUNING THE SONAR PIC- TURE How to Eliminate Unwanted Echoes Echoes from targets such as the bottom and fish return to the transducer in order of the distance to them, and when we compare their intensities at the transducer face, those from nearer targets are generally stronger when their reflecting properties are nearly equal.
Page 36 2. FINE TUNING THE SONAR PICTURE How to Suppress Bottom Tail As noted earlier, schools of fish (echoes) located near the bottom are sometimes dif- ficult to detect because you have to discriminate them from the bottom reflections. With [AGC Near], [AGC Far], or [TX Pulse Length] (in the [User Prg] menu) used prop- erly, the tail of bottom reflections is decreased, making it easier to discriminate bottom fish.
Page 37 2. FINE TUNING THE SONAR PICTURE 2. Select the [User Prg] tab from the main menu. 3. Select one of the following settings. • [Noise Suppression]: Suppresses noise from weak echoes such as sea clutter, plankton, and distant sea bottom. •...
Page 38 2. FINE TUNING THE SONAR PICTURE How to Reject Sonar Interference and Noise While observing the sonar picture, you may encounter occasional (or periodical) noise and interference. These are mostly caused by on-board electronic equipment, engine, propeller noise, or electrical noise from other sonars being operated on other ships nearby.
Page 39 2. FINE TUNING THE SONAR PICTURE 2. Select the [User Prg] tab from the main menu. 3. Select [Noise Limiter]. 4. Adjust the setting value (setting range: 0 to 10). The higher the setting, the greater the noise limiter effect. 5.
Page 40 2. FINE TUNING THE SONAR PICTURE 2.4.6 How to use echo average The echo average function adjusts echo afterglow - the amount of time an echo signal remains on the display. This feature can be useful for watching echo movement. Ad- just the setting so that targets are clearly visible on the display.
Page 41 ADVANCED SONAR OPERATION How to Track a School of Fish (Target Lock) The target lock function automatically tracks a school of fish so you will not lose sight of it on the display. Two types of target lock modes are available: position tracking (Target Mark) and tracking of school of fish (Fish).
Page 42 3. ADVANCED SONAR OPERATION Note: If the vector or track is not shown on the display, contact your dealer. If the target is lost, the target lock mark color changes from white to red, and the tracking mode changes to position mode (Target Mark) at that position. When the sonar detects and tracks the target again, the tracking mode (Fish) is restored.
Page 43 3. ADVANCED SONAR OPERATION 3.2.1 How to turn the audio on/off To enable the audio function, input from external devices is required (see page AP-7). 1. Open the menu. 2. Select the [Sonar] tab from the main menu. 3. Select the [Sonar] tab from the sub menu.

Page 46 3. ADVANCED SONAR OPERATION 3.3.2 How to set alarm level The alarm level sets the minimum echo strength at which the fish alarm is activated. The echo strength is equivalent to echo color. 1. Open the menu. 2. Select the [Sonar] tab from the main menu. 3.
Page 47 3. ADVANCED SONAR OPERATION Note 1: The time and distance between pressings of the FISH key should be as long as possible to increase accuracy of measurement. For more accurate measurement, repeat the procedure two or three times. Note 2: In the default arrangement, fish mark 1 can be entered on the echo display area by clicking on the display.
Page 48 3. ADVANCED SONAR OPERATION 3.4.2 How to delete fish marks You can delete fish marks individually or collectively. See page 9-6. Erase with the DELETE MARK key 1. Place the cross-hair cursor on the fish mark to delete. The fish mark color chang- es to red when the fish mark is correctly selected.
Page 49 3. ADVANCED SONAR OPERATION Event Mark The event mark is useful for finding the horizontal range, depth, and bearing to a lo- cation from the current position. There are two types of event marks: event mark 1 ) and event mark 2 ( ).

Page 89 HOW TO INTEREPRET THE DIS- PLAY Bottom Echo When the tilt angle is changed, the bottom echo appears on the screen. When the tilt angle is decreased, the bottom trace becomes wider and weaker. By observing the bottom condition on the screen, the skipper can prevent the net from being damaged by a reef of a shipwreck.
Page 90 8. HOW TO INTEREPRET THE DISPLAY School of Fish A school of fish appears as a mass of echoes. The color of the mass shows the den- sity. To know the distribution and center point of a school of fish, choose several dif- ferent tilt angles.
Page 91 8. HOW TO INTEREPRET THE DISPLAY Sea Surface Reflections To reduce sea surface reflections, set the tilt angle to 4° or more, so that the upper edge of the sonar beam does not hit sea surface, or adjust the near gain. When the sonar is used with a narrow tilt angle, the sea surface reflections cover a large area as illustrated below.
Page 92 8. HOW TO INTEREPRET THE DISPLAY False Echo by Sidelobe An ultrasonic wave is emitted only in the direction set by the TILT lever. However, in practice, there are some emissions outside the main beam, called sidelobes. Energy of the sidelobe is fairly weak, but when the sonar is used in comparatively shallow wa- ter with a hard and rocky bottom, strong target signals may be detected by the sidelo- be.
