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/lose 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.
Damaged or fouled
Check transducer condition, ensuring it is not
transducer
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.
