v System Configuration CSH-7040 TRANSCEIVER UNIT RECTIFIER RU-3424 100-115 VAC/ 200-230 VAC 1 φ , 50/60 Hz Ship’s Mains 24 VDC HULL UNIT 600 mm stroke 400 mm stroke CSH-7030 CSH-7031 * Interface Module CSH-7050 (option) required to connect external equipment.
1-1 OPERA TIONAL OVER VIEW Equipment Overview All operations of the CSH-7 are carried out through the display unit and the remote controller (option). The uncluttered, straight- forward control panel of the display unit provides intuitive op- eration.
1-2 Display Unit Control Panel Description GAIN TILT MENU F1 F2 R B – + – + TX d c Turns transmitter on/off; freezes the display. The lamp above the switch lights when the transmitter is turned on and flickers when off. Selects a picture display range.
1-3 Adjusting Screen Brilliance, Control Panel Backlighting The BRILL control adjusts screen brilliance, and the DIMMER control adjusts control panel backlighting. Lowering the T ransducer Press the d switch. The lamp above the switch blinks, and lights when the transducer is fully lowered.
1-4 Seabed echo and tilt angle Case 1: T ilt angle 30 to 40 degrees This 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 This tilt angle will only display half the seabed since it is only captured by the lower half of the beam.
1-5 Points to consider • Normally , a vertically distributed fish school is a better sonar tar get than the seabed, because it reflects the transmitted pulse back toward the transducer .
1-6 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.
1-7 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 MENU OVER VIEW The menu system consists of four menus: Scan menu, Menu-1, Menu-2, and System. The Scan menu can be opened while trans- mitting, and contains items which the user will often change during the course of operation. Menu-1 (similar to the Scan menu), Menu-2 and System menus can be opened with the trans- mitter turned off.
3-2 3. Operate the RANGE control to scroll the menu and select item. The selected item is highlighted in green and current setting in white. 4. Operate the GAIN control to change setting. 5. Press the MENU key to register selections and close the menu.

4-1 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.
4-2 4. Locate a fish school on a long range setting which is ap- proaching own ship. Adjust the tilt to keep the fish school in the center of the sonar beam, namely , fish school is displayed in strongest colors possible. Confirm that the fish echo is displayed in the same color as it approaches.
4-3 fish echoes from seabed reflections. Decrease the PULSELENGTH setting on the Scan menu to shorten the pulselength. For search of surface and midwater fish in which seabed reflections are not so strong, use the longest pulselength “10”.
4-4 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 .
4-5 Rejecting interference with TX cycle When other sonars operate nearby at the same transmission in- terval as that of own ship’ s sonar , an interference ring caused by other sonars is displayed. T o erase the interference ring from the screen, reduce the TX CYCLE setting on the Scan menu.
5-1 ADV ANCED OPERA TION Measuring the Range and Bearing to a T arget Operate the trackball to place the trackball marker (+) on the target you want to measure the range and bearing. The range and bearing are displayed at the top left corner on the screen.
5-2 Trackball marker Bearing marker Figur e 5-2 Ar ea monitor ed in audio function (sample) Relocating Fish School for Easy Observation When a fish school is located near the edge of the screen and inconvenient for observation, use the off-center function to re- locate the fish school to the desired place on the screen.
5-3 Function Keys (F1, F2) Function keys F1 and F2 work like the auto dialing feature on a telephone, instantly calling out desired settings to perform spe- cially assigned functions. These keys provide optimum sonar settings for a specific purpose with a single key operation.
5-4 Programming user programs 1. Press the TX switch to blink the lamp above it, if it is not already blinking. 2. Press the MENU key and select Menu-1. 3. Using the RANGE and GAIN controls, set menu options as desired. 4. Operate the RANGE control to select USER PROG.
5-5 Event Markers, Own Ship Event Markers The event marker denotes important items on the display , such as a fish school, and the own ship event marker marks own ship position. T en event markers and ten own ship event markers may be entered. The CSH-7 denotes the latest event marker as and other event markers as +.
6-1 INTERPRETING THE DISPLA Y Seabed Echoes When the tilt angle is widened, the seabed echo illustrated be- low will appear on the display . When the tilt is narrowed, the seabed trace becomes wider and weaker . By observing the sea- bed condition on the display , the skipper can prevent net dam- age.
6-2 Fish Schools 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 find distribution and center point of a fish school, try several different tilt angles.
6-3 Sea Surface Reflections T o reduce sea surface reflections, set the tilt angle to 5 ° or higher, so the upper edge of the sonar beam does not hit the sea surface, or adjust TVG. When a narrow tilt angle is used, sea surface reflections cover a large area as illustrated below .
6-4 False Echo by Sidelobe An ultrasonic wave is emitted only in the direction set by the TIL T lever , however there are some emissions outside the main beam.
7-1 MAINTENANCE Do not work inside the equipment unless totally familiar with electrical circuits. Hazardous voltage which can cause electrical shock, burn or serious injury exists inside the equipment. WARNING Display Unit Maintenance Keep magnets and cassette tapes away from the display unit.
7-2 Hull Unit Maintenance HULL UNIT Raise transducer and coat main shaft with DAPHAECOROAEX #2 every six months. Apply MOLYTONE grease #2 every six months. Dry dock ship and clean transducer face yearly. Apply single coat of "MARINE STAR 20 Mod (Red-N)" anti-foulant to transducer face to keep marine life off the transducer.
