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
Fishfinder 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
Check product and transducer documentation and ensure that the
transducer is compatible with your system.
External sonar module:
SeaTalkhs / RayNet network
problem.
• Check that the unit is correctly connected to the MFD or network
switch. 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.
