Raymarine E SERIES Installation Instructions Manual page 73

Possible causes
Vessel speed too high
Bottom too shallow or too deep
Poor / problematic image
Possible causes
Vessel stationary
Scrolling paused or speed set too low
Sensitivity settings may be inappropriate for
present conditions.
Damaged cables
Transducer location
Transducer kicked-up
Damaged or fouled transducer
Damaged transducer cable
Turbulence around the transducer at higher
speeds may affect transducer performance
Interference from another transducer
Unit power supply fault
Incorrect speed reading (from DST transducer)
Possible causes
Paddle wheel fault
No speed offset set
Incorrect calibration
Troubleshooting
Possible solutions
6. 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.
Slow vessel speed and recheck.
The bottom depth may be outside of the transducers depth range, move vessel
to shallower or deeper waters as relevant and recheck.
Possible solutions
Fish arches are not displayed if the vessel is stationary; fish will appear on the
display as straight lines.
Unpause or increase sonar scrolling speed.
Check and adjust sensitivity settings or perform a Sonar reset.
1. Check the unit's connector for broken or bent pins.
2. Check that the cable connector is fully inserted into the unit and that the
locking collar is in the locked position.
3. Check the cable and connectors for signs of damage or corrosion, replace
if necessary.
4. With the unit turned on, try flexing the power cable near to the display
connector to see if this causes the unit to re-boot/loose power, replace
if necessary.
5. 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.
6. 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 that the transducer has been installed in accordance with the instructions
provided with the transducer.
If a transom mount transducer is mounted too high on the transom it may be
lifting out of the water, check that the transducer face is fully submerged when
planing and turning.
If the transducer has a kick-up mechanism, check that it has not kicked up due to
hitting an object.
Check the condition of the transducer ensuring it is not damaged and is free
from debris / fouling.
Check that the transducer cable and connection is free from damage and that
the connections are secure and free from corrosion.
Slow vessel speed and recheck.
1. Turn off the transducer causing the interference.
2. Reposition the transducers so they are further apart.
Check the voltage from the power supply, if this is too low it can affect the
transmitting power of the unit.
Possible solutions
Check that the paddle wheel is clean.
Add speed offset.
Re-calibrate equipment
