6.4 Sonar troubleshootingProblems with the sonar and their possible causes and solutions are described here.Scrolling image is not being displayedPossible causes Possible solutionsSonar disabled Select Ping Enable from the Fishfinder app’s Sounder menu.Incorrect transducer selected Check that the correct transducer is selected in the Fishfinderapp’s Transducer menu.Damaged cables 1. Check that the transducer cable connector is fully insertedand locked in position.2. Check the power supply cable and connectors for signsof damage or corrosion, replace if necessary.3. With the unit turned on, try flexing the cable near tothe display connector to see if this causes the unit tore-boot/loose power, replace if necessary.4. Check the vessel’s battery voltage, the condition of thebattery terminals and power supply cables, ensuringconnections are secure, clean and free from corrosion,replace if necessary.5. With the product under load, using a multi-meter, checkfor high voltage drop across all connectors/fuses etc (thiscan cause the Fishfinder applications to stop scrolling orthe unit to reset/turn off), replace if necessary.Damaged or fouled transducer Check the condition of the transducer ensuring it is notdamaged and is free from debris/fouling, clean or replace asnecessary.Wrong transducer fitted Ensure the transducer is compatible with your system.External sonar module:SeaTalkhs ™ / RayNet networkproblem.• Check that the unit is correctly connected to themultifunction display or Raymarine network switch. If acrossover coupler or other coupler cable / adapter is used,check all connections ensuring connections are secure,clean and free from corrosion, replace if necessary.External sonar module: Softwaremismatch between equipmentmay prevent communication.Ensure all Raymarine products contain the latestavailable software, check the Raymarine website:www.raymarine.com/software for software compatibility.No depth reading / lost bottom lockPossible causes Possible solutionsTransducer location Check that the transducer has been installed in accordancewith the instructions provided with the transducer.Transducer angle If the transducer angle is too great the beam can miss thebottom, adjust transducer angle and recheck.Transducer kicked-up If the transducer has a kick-up mechanism, check that it hasnot kicked up due to hitting an object.Power source insufficient With the product under load, using a multi-meter, check thepower supply voltage as close to the unit as possible toestablish actual voltage when the current is flowing. (Checkyour product’s Technical specification for power supplyrequirements.)Damaged or fouled transducer Check the condition of the transducer ensuring it is notdamaged and is free from debris / fouling.Troubleshooting 59
