10 4. BASIC OPERA TION General This section provides information necessary for basic operation of the CSH-5 MARK-2, from turning the power on and off to detecting and tracking fish schools. The basic operating procedure is shown below . Basic Operating Procedure 2 / 7 Lower/raise transducer .
11 Power Off Press the TRANSDUCER “ ” switch on the control box. W ait until the lamp above the switch lights, and then press the POWER “ OFF ” switch. Note that the transducer automatically retracts into the tank even if the POWER “ OFF ” switch is pressed without raising the transducer (by pressing the TRANSDUCER “ ” switch).
12 Seabed Echo vs Tilt Angle Case 1: T ilt Angle 30 to 40 degrees A wide tilt angle will display the entire seabed since it is captured by the full width of the beam. Case 2: T ilt Angle 10 to 20 degrees A narrow tilt angle will display only half the seabed since it is cap- tured by only the lower half of the beam.
13 Points to Consider • As a general rule of thumb, a vertically distributed fish school is a better sonar tar get than the seabed, since it reflects the transmitted pulse back toward to the source. • In case 3, both fish schools a and b are presented.
14 TIL T ANGLE T ilt angle vs. Beam Coverage 20 (40) 40 (80) 60 (120) 80 (160) 100 (200) 200 (400) Depth m 100 (200) 200 (400) 300 (600) 400 (800) Range m 0 ° 5 ° 10 ° 15 ° 13 ° 23m 100m 46m 200m.
15 Adjusting the Gain The gain should be adjusted to see fish echoes clearly with minimal noise on the screen. T oo high a setting not only causes excessive noise on the screen and makes it difficult .
16 5. FINE TUNING THE PICTURE General In the previous chapter basic operation of the sonar was presented. This chapter describes the procedures for fine tuning the sonar pic- ture.
17 3. Locate a fish school on a long range setting 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.
18 Suppressing Seabed and Sea Surface Reflections in Shallow Fishing Grounds In shallow fishing grounds with hard or rocky bottom, seabed reflec- tions often interfere with wanted fish echoes and they.
19 Rejecting Noise with IR Control This control is similar to the interference rejector on echo sounders and radars. It is effective for rejecting random noise and sea surface reflections in rough sea conditions. Set the IR control to positions “1” thru “3” so that noise is just eliminated.
20 6. ADV ANCED OPERA TION General It this section, how to use the CSH-5 MARK-2 effectively in actual fishing operations is presented. Measuring Range and Bearing to a T arget T o measure the range and bearing to a target, use the trackball. Procedure 1.
21 Procedure 1. Move the trackball mark “ ” to the direction you want to moni- tor through the speaker , by operating the trackball. 2. Press the R/B key . The bearing marker will appear in the direction of the trackball mark and echoes in that direction are monitored through the speaker .
22 2. Press the OFF-CENTER key on the front panel. 3. T o move the own ship mark back to the center of the screen, press the OFF-CENTER key again. Finding Fish School Center When you want to find the center depth of a fish school, use the auto tilt function which automatically scans the tilt angle within the se- lected width.
23 Registering Procedure 1. Press the MENU key . 2. Rotate the RANGE control to select FUNC KEY PROG. 3. Rotate the GAIN control to select FUNC1 or FUNC2. 4. Press the TX key . Each time the TX key is pressed, the current settings in the scan menu and E/S menu are recorded.

26 8. INTERPRETING THE DISPLA Y General This section provides information necessary for interpreting the display . Interpreting the Display Seabed When the tilt angle is changed, the seabed echo illustrated below will appear on the screen. When the tilt angle is decreased, the seabed trace becomes wider and weaker .
27 Fish School A fish school appears as a mass of echoes on the screen. The color of the mass shows the density of fish schools on the sonar beam. T o know the distribution and center point of a fish school, the tilt should be changed to several different angles.
28 Sea Surface Reflections T o reduce the sea surface reflections, set the tilt angle to 5 ° or more so that the upper edge of the sonar beam may not hit sea surface, or adjust TVG functions. When the sonar is used with a narrow tilt angle, the sea surface reflections cover lar ge area (up to 300 m to 400 m) as illustrated below .
29 False Echo by Sidelobe In the preceding chapters, it was explained that an ultrasonic wave is emitted only in the direction set by the TIL T lever , but, in practice, there are some emissions outside the main beam that are called “sidelobes”.
30 9. W ARNING Overvoltage W arning If the supply voltage rises about 20% to over the rated value, the overvoltage detection circuit is actuated. The following warning flick- ers at the center of the screen and an alarm sounds.

58 14. CHARACTERISTICS OF THE UL TRASONIC W A VE IN W A TER The purpose of this chapter is to provide an overview of the charac- teristics of the ultrasonic wave in water .
59 Research in the waters throughout the world has revealed that there is a difference of approximately 100 m/s between the areas where the velocity is maximum and minimum Generally , the velocity increases as follows, provided that salinity density is constant: • 3 m/s for every 1 degree rise of water temperature • 1.
60 Refraction An ultrasonic wave transmitted in water does not travel straight but is more or less refracted. This refraction is caused by the variation of propagation velocity in water .
61 The drawing below shows how temperature variation affects sound propagation with respect to different emitting directions (tilt angles). Beams tilted five and ten degrees bend upward at 400 m and 600 m points respectively . Beams tilted down more than 15 degrees travel in almost straight lines.
62 The product of the density (P) and the velocity (C) is called intrinsic acoustic impedance and in the boundary between two media which has extremely different C from each other , most of the acoustic power is reflected and only a small portion penetrates.
