OPERATIONAL OVERVIEW Control Unit All operations are carried out from the control unit. All controls quickly respond to the operator’s command and the associated reaction can be seen on the screen almost immediately. Lowers the transducer. Raises the transducer. Turns power on/off.
1. OPERATIONAL OVERVIEW Remote Controller (option) The remote controller provides armchair control of the tilt, range, gain and menu functions. TILT Control : Increases tilt angle. : Decreases tilt angle. RANGE Control : Increases range. : Decreases range. Chooses menu item in menu operation.
Basic Operating Procedure 1.3.1 Turning on the power 1. Press the POWER switch on the control unit to turn on the power. 2. Turn on the monitor (user supply). The system initiates the START UP test to check itself for proper operation. The results are shown as OK or NG (No Good).
1. OPERATIONAL OVERVIEW 1.3.3 Transmitting TRANSMISSION in the SONAR menu is off in the default setting. If it is has been set to ON, the procedure below is not necessary. When the transducer is lowered, transmission starts and when it is raised transmission is stopped. 1.

1. OPERATIONAL OVERVIEW 1.3.5 Choosing a display mode Three display modes are available: NORMAL, COMBI-1 and COMBI-2. To choose the display mode, do the following: 1. Press the [MENU] key to open the menu. The last-used menu is displayed. 2. Use the [RANGE] control to choose [MENU MODE] at the top of the screen. 3.
1. OPERATIONAL OVERVIEW COMBI-2 display (sonar display + echosounder display) COMBI-2 display (sonar display + echosounder display) 1.3.6 Choosing the display range The [RANGE] control chooses a display range. Each time the range is changed the newly selected range appears in large characters for five seconds at the top of the sonar display.
1.3.7 Adjusting the gain The [GAIN] control adjusts receiver sensitivity. It should be adjusted to see fish echoes clearly with minimal noise on the screen. Too high a setting not only causes excessive noise on the screen and makes it difficult to discriminate wanted fish echoes but also causes bottom echoes to be painted in strong colors, resulting that the echoes from bottom fish are masked by bottom reflections.
1. OPERATIONAL OVERVIEW Setting the Tilt Angle The tilt angle shows the direction to which the sound wave is emitted. When the sound wave is emitted horizontally, it is said to be zero (0) degrees and when emitted vertically, 90 degrees. To set a tilt angle, operate the TILT lever for the desired angle while watching the tilt angle indication at the top right corner of the sonar display.
Range (m) 50, 85, 100, 150, 200, 250, 300, 350 400, 450, 500 600, 800 1000, 1200, 1600 For example, when the [RANGE] control, [TILT] lever and automatic tilt are set to 1000 m, 8 and ±2-10° respectively, the tilt angle changes at each transmission as follows: 1.
1. OPERATIONAL OVERVIEW 1.4.2 Bottom and tilt angle 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 50-100 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.
1.4.4 Points to consider As a general rule of thumb, a vertically distributed fish school is a better sonar target than a horizontally one, since it reflects the transmitted pulse back toward to the source. In case 3, both fish schools (a) and (b) are presented. Generally speaking, however, midwater fish schools tend to be larger than bottom fish schools and they are often displayed near the bottom on the sonar screen.
1. OPERATIONAL OVERVIEW 1.4.6 Suitable tilt angle The table below shows the estimated detection range for tilt angles of 0, 5, 10 and 15 degrees. Refer to the table to find suitable tilt angle from depth and detection range. Tilt angle setting (200) 20(40) 40(80)
Sonar Menu Overview This equipment has four menus: sonar menu, sounder menu, marks menu and system menu. Of the four menus, the SONAR menu is the one you will use most often. Note that the gain and range cannot be adjusted while the menu is displayed. 1.6.1 Operating procedure 1.
1. OPERATIONAL OVERVIEW 4. Use the [RANGE] control to choose a menu item. The selected item is highlighted. Note: Items displayed in red are locked to prevent accidental change of setting. When any of those items are selected the display shown below appears, to ask you if you are sure to change the setting.
Description of sonar menu (con’t from previous page) Item COLOR Adjusts color level against strong reflections. The higher the setting, the more the red color is RESPONSE displayed and weak level colors are displayed as is, thereby giving the appearance that the gain has been raised.
2. FINE TUNING THE SONAR PICTURE 8. On a long range, locate a fish school which is approaching own ship. Note that the tilt should be kept adjusted so that the fish school is always placed in the center of the sonar beam, i.e., so that the fish school is displayed in strongest colors possible.
2.3.2 Pulse length The pulse length control determines the length of the transmission pulse emitted into the water. While a longer pulse is advantageous for long-range sounding, it has the disadvantage of being poor in discrimination of targets, i.e., ability to separate several closely located targets.
2. FINE TUNING THE SONAR PICTURE Suppressing Bottom and Sea Surface Reflections in Shallow Fishing Grounds In shallow fishing grounds with hard or rocky bottom, bottom reflections often interfere with wanted fish echoes and they can not be eliminated sufficiently with the aforementioned TVG and AGC, especially when the tilt angle is large in order to track fish schools approaching within 400 m.
Rejecting Sonar Interference and Noise While observing the sonar picture, you may encounter occasional or intermittent noise and interference. These are mostly caused by on-board electronic equipment, engine or propeller noise, or electrical noise from other sonars being operated nearby. 2.5.1 Identifying noise source To eliminate noise effectively, you should first identify the noise source.
2. FINE TUNING THE SONAR PICTURE 2.5.4 Rejecting interference with TX cycle When other sonars of the same TX frequency as own sonar are near, an interference ring caused may be displayed. To erase the interference ring from the screen, reduce the TX CYCLE setting. Tx cycle high 1.
Choosing Beamwidth 2.6.1 Horizontal beamwidth If you wish to have better bearing discrimination (ability to distinguish two closely located targets at the same range and different bearings) for fish schools and also wish to examine the contour of bottom, set HOR BEAMWIDTH to NARROW, on the SONAR menu.
ADVANCED SONAR OPERATION Tracking a Fish School (target lock) Target lock, which requires speed and heading inputs, automatically tracks a fixed location (such as a reef) so that you won’t lose sight of it on the display screen. 1. On the sonar display, operate the trackball to place the trackball mark on the location you want to track.
3. ADVANCED SONAR OPERATION Note 3: The target lock feature tracks a target up to 55° tilt angle. For example, if a ship moves from position A to position D, the target lock works between positions A and B. The tilt angle is fixed between positions B and C is 55°, however calculation continues internally.
Detecting Fish Schools Aurally Sometimes you may 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 fish schools and bottom through the built-in speaker.
3. ADVANCED SONAR OPERATION The Fish Alarm The fish alarm generates an audio alarm when a fish echo above a certain strength enters the alarm zone. 1. Operate the trackball to place the trackball mark on the starting point of the alarm zone.
Measuring Fish School Speed To ensure a good haul, it is important to estimate the direction and speed of the fish school before shooting the net. You can do this with the [FISH] key. If the tidal current data is used together with fish speed data, you can determine the timing of the net shooting more efficiently.
3. ADVANCED SONAR OPERATION Note 3: Each time the [FISH] key is pressed the fish mark changes in the sequence shown below. Maximum 10 fish marks may be inscribed, one latest, one 2 Fish key pressed once: Fish key pressed twice: Fish key pressed three times: Fish key pressed four times: 3.4.2...
Event Mark, Own Ship Position Mark 3.6.1 Event mark The event mark, which requires speed and heading data, is useful for finding the horizontal range, depth and bearing to a location some distance from current position. Plotting an event mark on the display is equivalent to dropping a buoy with an anchoring chain that extends from surface to bottom.
3. ADVANCED SONAR OPERATION Each time the key is pressed the appearance of the event marks changes as below. Ten marks may be entered. When this amount is exceeded the oldest event mark is automatically erased. 3.6.2 Entering an own ship position mark Operate the trackball to place the trackball mark on the own ship mark and press the [EVENT] key to inscribe an own ship position mark.
Collectively Deleting Marks You may collectively delete track, event marks or fish marks as shown below. Own ship position mark may be also be deleted, one by one. 1. Press the [MENU] key to open the menu. 2. Use the [RANGE] control to choose [MENU MODE] at the top of the screen. 3.
3.

Suppressing Effects of Pitching and Rolling (Stabilizer) The Motion Sensor MS-100 (option) compensates for the affects of pitching and rolling to provide steady, non-fading pictures, along the bearing selected. Follow the procedure below to use the stabilizer feature. 1. Operate the trackball to place the trackball mark on the bearing where you want the stabilizer the picture.
3. ADVANCED SONAR OPERATION 3. To turn off the stabilizer, press the [STABILIZER] key. The stabilizer mark, stabilizer indication and stabilizer bearing data are erased. If range and bearing marks are shown they are displayed along with their data. Note 1: The tilt angle can be manually set in the range of 0-55°, however pitching and rolling are compensated within the ±20°...
ECHOSOUNDER MODE This chapter covers operation of the echosounder picture, which may be displayed by choosing the COMBI-2 mode. Choosing the Range The basic range and range shifting functions together give you the means to select the depth you can see on the screen. The basic range can be thought of as providing a “window”...
4. ECHOSOUNDER SOUNDER MENU [MENU MODE] PRESS [MENU] KEY TO EXIT 4. Use the [RANGE] control to choose RANGE. 5. Use the [GAIN] control to choose range desired among 20, 40, 80, 120, 160, 240 and 320 (meters). 6. To shift the display, use the [RANGE] control to choose SHIFT. 7.
Picture Advance Speed The picture advance speed determines how quickly the vertical scan lines run across the screen. When selecting a picture advance speed, keep in mind that a fast advance speed will expand a fish school horizontally and a slow advance speed will contract it.
4. ECHOSOUNDER Suppressing Interference Interference from other sounders or electrical interference shows itself on the screen as in the illustration below. To remove interference, do the following: 1. Press the [MENU] key to open the menu. 2. Use the [RANGE] control to choose [MENU MODE] at the top of the screen. 3.

5. MARKS AND DATA Description of marks and data on the echosounder and audio displays Mark/Data Color Bar The color bar provides an estimate of echo strength in 16 colors. The red color is the strongest echo signal. Depth Scale, Range The depth scale and range scale provide an estimate of depth and range in the echosounder and audio displays, respectively.
INTERPRETING THE DISPLAY Bottom Echo When the tilt angle is changed, the bottom echo will appear 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 or a shipwreck.
6. INTERPRETING THE DISPLAY Fish School A fish school appears as a mass of echoes. The color of the mass shows the density. To know the distribution and center point of a fish school, choose several different tilt angles. (A) Sea surface fish Tilt angle: 0˚...
Sea Surface Reflections To reduce sea surface reflections, set the tilt angle to 5 or more so that the upper edge of the sonar beam does not hit sea surface, or adjust the TVG functions. When the sonar is used with a narrow tilt angle, the sea surface reflections cover a large area (up to 300 m to 400 m) as illustrated below.
6. INTERPRETING THE DISPLAY False Echo by Sidelobe An ultrasonic wave is emitted only in the direction set by the [TILT] lever but, in practice, there are some emissions outside the main beam that are called “sidelobes.” Energy of the sidelobe is fairly weak but when the sonar is used in comparatively shallow water with a hard and rocky bottom, strong target signals are detected by the sidelobe.
MARKS AND SYSTEM MENUS This chapter describes the MARKS and SYSTEM menus. To display the SYSTEM or MARKS menu, do the following: 1. Press the [MENU] key to open the menu. 2. Use the [RANGE] control to [MENU MODE] at the top of the screen. 3.
