When the waters are rough or the boat passes over a wake surface noise may appear near the zero line As surface turbulence is acoustically equivalentto running into a brick wall the bottom echo will be displayed intermittently Similar noise sometimes appears when a water temperature difference thermocline exists Different species of fish tend to prefer different temperature zones so the thermocline may be useful to help identify target fish 200KHz tends to show shallow thermoclines better than 50KHz In rough waters the display is occasionally interrupted due to below the ship air bubbles obstructing the sound path This also occurs when the boat makes a quick turn or reverses movement Lowering the picture advance speed may reduce the interruption However reconsideration of the transducer installation may be necessary if the interruption occurs frequently Surface noise Caused by aerated BOT Thermocline 3 2 4 MAINTENANCE TROUBLESHOOTING A WARNING ELECTRICAL SHOCK HAZARD Do notopen the equipment Only qualified personnel should work inside the equipment 4 1 Maintenance Regular maintenance is important for good performance Following the recommended maintenance procedures will help keep your set in good working condition 4 1 1 General checking Important points to be checked from time to time are tabulated below Maintenance check points Checkpoint Aem If outof ratings corre
