Possible causes Possible solutions
Sonar disabled Select Enable Sonar from the Shortcuts page.
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 lexing 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 Fishinder applications to
stop scrolling or the unit to reset/turn off), replace if necessary.
Damaged or fouled transducer Check the condition of the transducer ensuring it is not damaged and is free from
debris/fouling, clean or replace as necessary.
Wrong transducer itted The CPT-DV transducer is a DownVision
™
only transducer, you cannot use the
Sonar application with a CPT-DV transducer connected. If you have a DVS
or Pro variant display ensure you are using a dual element transducer such
as the CPT-DVS .
Refer to 3.3 DownVision
™
transducer compatibility for transducer compatibility.
No depth reading / lost bottom lock
Possible causes Possible solutions
Transducer location Check that the transducer has been installed in accordance with the transducer
location requirements (refer to Selecting a location for the transducer of the
manual for details).
Transducer angle If the transducer angle is too great the beam can miss the bottom, adjust
transducer angle and recheck.
Transducer kicked-up Check that the transducer hasn't kicked up due to hitting an object.
Power source insuficient With the product under load, using a multi-meter, check the power supply
voltage as close to the unit as possible to establish actual voltage when the
current is lowing. (Refer to Chapter 13 Technical speciication for power supply
requirements.)
Damaged or fouled transducer Check the condition of the transducer ensuring it is not damaged and is free
from debris / fouling.
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 lexing 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.
