CAUTION ON SAFETY (BE SURE TO READ THIS) This explains the important cautions in order to prevent the users and surrounding people from physical injuries and property damages. 1. HANDLING OF MAIN UNIT DANGER High voltage is used for the unit inside. No one besides authorized personnel should disassemble or modify the unit.
CAUTION Do NOT install the unit where rain or spray dashes hit directly. It causes the firing and electric shock. Do NOT install the unit at heated places. It causes the firing from the increase of internal temperature, injury, and electric shock. Use the earthing.
3. HANDLING TRANSDUCER AND WATER TEMP SENSOR DANGER Any works on the vessel are very unstable and risky. Installation/Maintenance of transducer and water temp sensor should be handled after landing the vessel on ground or fixing the vessel at shipyard etc. WARNING Be sure to ventilate well inside the vessel when installing the transducer at the bottom of vessel.
5. HANDLING OF GPS DANGER Do NOT work on GPS while piloting. The work such as installation or maintenance should be carried out on ground. CAUTION Place GPS antenna at highest location as possible for stable GPS signal. Searching time for GPS signals take longer, and GPS accuracy becomes lower if any obstacles are located near by GPS antenna.
7. OPERATION Power OFF when starting engine. Battery voltage varies when the engine starts. It may cause some damages onto the unit. Set the power OFF when starting the engine. Power Supply 11-35V Operate the unit within the range of DC11-35V. Organic solution is prohibited.

2 Raise 2pcs side covers. 3 Remove the covers. 4 Flash-mount it. 5 Fix with 4pcs 4×30 screws. 6 Put the side covers back.
TRANSDUCER INSTALLATION DANGER Any works on the vessel are very unstable and risky. Installation/maintenance of transducer should be handled after landing the vessel on ground or fixing the vessel at shipyard etc. If not, it may cause serious injuries. WARNING Be sure to ventilate well inside the vessel when installing the transducer at the bottom of vessel.
1 INSIDE-HULL Effective for FRP vessels with single hull layer of 10mm or less. Size and shape vary for each transducer. Look for the best picture location before the fixation by putting adequate water on the transducer surface and vessel bottom followed by pressing the transducer onto the vessel bottom.
WATER TEMP. SENSOR INSTALLATION Water temp sensor: Option DANGER Any works on the vessel are very unstable and risky. Installation/maintenance of water temp sensor should be handled after landing the vessel on ground or fixing the vessel at shipyard etc. If not, it may cause serious injuries. Do not operate the electronic tools with wet hands.

THEORY OF ECHO SOUNDER 1 Theory of Echo Sounder Theory of echo sounder is same as echo among hills. Ultrasonic wave transmitted from the transducer directly beneath the vessel is reflected at the sea bottom and received by transducer. Echo sounder indicates the depth by calculating the round-trip time to distance. Also, the unit shows the color image of fish school size/density or sea floor condition according to the strength of reflected wave.

2 Distinguish of Fish School Important tip is comparison between fish school image and actual fish. Possible to judge the fish type to some extent from the image of fish school. The shape of fish school changes even for same fish group by time (day/night, season, current change).
TROUBLE SHOOTING When the unit has any problems, please check the following points before returning the unit for repair. Symptom Cause Remedy Power cannot be Voltage of battery is lower Recharge the battery. turned ON. than standard value (11V). Contact of power connector is Retighten it.

Symptom Cause Remedy Too much noise. Too high sensitivity. Lower the sensitivity. Set to auto gain (auto gain control) Interference with other Noise disappears after other vessel's echo sounder. vessel moves far away. Noise from engine. Change the routing of cables such as transducer and power cables.
