If it doesn’t press the TX switch on sub panel 1. T urning the power off Retract the transducer with the c switch and then press the OFF switch on the main panel.
2-2 Selecting a Display Mode The CSH-83/84 provides three display modes: normal sonar pic- ture, echo sounder(E/S) combination, and history display com- bination. Those modes may be selected with the NORM, E/S and HIST keys. T able 2-1 Display mode description Mode Description The sonar picture appears over the entire screen.
2-3 Selecting a Display Range Operate the RANGE control to select a display range. The range selected appears at the top of the screen. Setting the T ilt Angle The tilt angle shows the direction to which the sound wave is emitted.
2-4 How to discriminate fish echoes from the seabed The figure below illustrates how two fish schools a and b are displayed on the screen using three different tilt angles. Case 1: T ilt angle 30 to 40 degrees. Fish school is obscured by the seabed. Case 2: T ilt angle 10 to 20 degrees.
2-5 Tilt angle for surface fish Sound emitted from the sonar transducer forms a circle-shaped beam with a width of approximately 12 degrees 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.
2-6 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 Adjusting the Gain The GAIN control adjusts receiver sensitivity (gain). Adjust it so fish echoes are clearly displayed with minimal noise on the screen.

3-1 FINE TUNING THE PICTURE Eliminating Unwanted Feeble Echoes Echoes from targets such as seabed and fish return to the trans- ducer in order of 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.
3-2 4. When sea surface reflections or plankton layers disturb the picture, decrease appropriate TVG option by one or two steps by pressing – (minus) key . 5. Locate fish school on a long range setting (about 800 meters) which is approaching own ship.
3-3 Suppressing Seabed T ail AGC (data setting window: SIGNAL, SIGNAL PROCESS) The AGC functions to automatically reduce the receiver gain only against strong echoes such as the seabed or a large fish school. Since weak echoes remain unaffected, a small fish school becomes easier to detect.
3-4 Suppressing Seabed and Sea Surface Reflections in Shallow W aters Data setting window: TVG•TX, OUTPUT In shallow fishing grounds with hard or rocky bottom, seabed reflections often interfere wit.
3-5 1. T urn off the TX switch and operate all on-board equipment one by one while observing the picture. 2. Run the boat at various speeds to check if the noise is speed dependent.
3-6 Setting Noise limiter (data setting window: SIGNAL, SIGNAL PROCESS) W eak, unwanted reflections, colored light-blue or green, appear when the water is dirty , plankton layers exists, or due to ship’ s noise.
