Possible causes
Vessel speed too high
Bottom too shallow or too deep
Poor / problematic image
Possible causes
Scrolling paused
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

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.
Note: The Sonar channel will be able to hold bottom at higher speeds than
the DownVision
channel.
™
The bottom depth may be outside of the transducers depth range, move vessel
to shallower or deeper waters as relevant and recheck. (Refer to
Technical specification
for transducer depth range.)
Note: Depending on water conditions, the Sonar channel maybe able to
achieve increased depth range over the DownVision
Possible solutions
From Cursor mode, press the Back button to enter scrolling mode.
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 power supply 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.
The presence of thin lines at a constant depth may be a reflection of structures
on the bottom of the vessel check that the transducer has been installed in
accordance with the transducer location requirements (refer to
location for the transducer
of the manual for details).
If the 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.
Check that the transducer hasn't 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.
