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 flexing 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 fitted
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:
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 insufficient
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 flowing. (Check
your product’s Technical specification 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.
