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.
Check transducer condition, ensuring it is not damaged and is free
from debris/fouling. If necessary, clean or replace your transducer.
After cleaning or replacement coat the transducer using a
water-based anti-fouling paint.
Check product and transducer documentation and ensure that the
transducer is compatible with your system.
• Check that the unit is correctly connected to the Display or
network switch. Check all connections ensuring connections are
secure, clean and free from corrosion, replace if necessary.
Ensure all Raymarine products contain the latest available software,
check the Raymarine website:
software compatibility.
Possible solutions
Check that the transducer has been installed in accordance with
the instructions provided with the transducer.
If the transducer angle is too great the beam can miss the bottom,
adjust transducer angle and recheck.
If the transducer has a kick-up mechanism, check that it has not
kicked up due to hitting an object.
