Possible causes
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.
Vessel speed too high
Slow vessel speed and recheck.
Note:
The Sonar channel will be able to hold bottom at higher speeds than
the
DownVision
™
channel.
Bottom too shallow or too deep
The bottom depth may be outside of the transducers depth range, move vessel
to shallower or deeper waters as relevant and recheck. (Refer to
for transducer depth range.)
Note:
Depending on water conditions, the Sonar channel maybe able to
achieve increased depth range over the
DownVision
™
channel.

Possible causes
Possible solutions
Scrolling paused
From Cursor mode, press the
Back
button to enter scrolling mode.
Sensitivity settings may be inappropriate for
present conditions.
Check and adjust sensitivity settings or perform a Sonar reset.
Damaged cables
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.
Transducer location
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
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.
Transducer kicked-up
Check that the transducer hasn't kicked up due to hitting an object.
Damaged or fouled transducer
Check the condition of the transducer ensuring it is not damaged and is free
from debris / fouling.
Damaged transducer cable
Check that the transducer cable and connection is free from damage and that
the connections are secure and free from corrosion.
Turbulence around the transducer at higher
speeds may affect transducer performance
Slow vessel speed and recheck.
Interference from another transducer
1. Turn off the transducer causing the interference.
2. Reposition the transducers so they are further apart.
