Possible solutions
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 Sonar 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.
