28.6 Sonar troubleshooting
Problems with the sonar and their possible causes and solutions are described here.
Scrolling image is not being displayed
Possible causes Possible solutions
Sonar disabled Select Ping Enable from the Sonar app’s Sounder menu.
Incorrect transducer selected
Check that the correct transducer is selected in the Sonar app’s Transducer
menu.
Damaged cables
1. Check that the transducer cable connector is fully inserted and locked in
position.
2. Check the power supply cable and connectors for signs of damage or
corrosion, replace if necessary.
3. With the unit turned on, try exing the cable near to the display connector to
see if this causes the unit to re-boot/loose power, replace if necessary.
4. Check the vessel’s battery voltage, the condition of the battery terminals
and power supply cables, ensuring connections are secure, clean and free
from corrosion, replace if necessary.
5. With the product under load, using a multi-meter, check for high voltage drop
across all connectors/fuses etc (this can cause the Sonar applications to
stop scrolling or the unit to reset/turn off), replace if necessary.
Damaged or fouled transducer Check the condition of the transducer ensuring it is not damaged and is free from
debris/fouling, clean or replace as necessary.
Wrong transducer tted
Ensure the transducer is compatible with your system.
External sonar module: SeaTalkhs™ /
RayNet network problem.
• Check that the unit is correctly connected to the multifunction display or
Raymarine network switch. If a crossover 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: Software
mismatch between equipment may prevent
communication.
Ensure all Raymarine products contain the latest available software, check the
Raymarine website:
www.raymarine.com/software for software compatibility.
No depth reading / lost bottom lock
Possible causes Possible solutions
Transducer location
Check that the transducer has been installed in accordance with the instructions
provided with the transducer.
Transducer angle
If the transducer angle is too great the beam can miss the bottom, adjust
transducer angle and recheck.
Transducer kicked-up
If the transducer has a kick-up mechanism, check that it has not kicked up due to
hitting an object.
Power source insufcient
With the product under load, using a multi-meter, check the power supply
voltage as close to the unit as possible to establish actual voltage when the
current is owing. (Check your product’s Technical specication for power supply
requirements.)
Damaged or fouled transducer Check the condition of the transducer ensuring it is not damaged and is free
from debris / fouling.
