Troubleshooting
Before contacting the Humminbird Technical Support, please read the following
section. Taking the time to review these troubleshooting guidelines may allow you
to solve a performance problem yourself, and therefore avoid sending your unit back
for repair.
Fishing System Doesn’t Power Up
If your Fishing System doesn’t power up, use the installation guide that is included
with your Fishing System to confirm specific details, making sure that:
• the power cable is properly connected to the Fishing System control head,
• the power cable is wired correctly, with red to positive battery terminal and
black to negative terminal or ground,
• the fuse is operational, and
• the battery voltage of the power connector is at least 12 Volts.
Correct any known problems, including removing corrosion from the battery
terminals or wiring, or actually replacing the battery if necessary.
NOTE:
Do not wipe the screen while dirt or grease is on the screen.
•
Control Head:
If the control head comes into contact with salt spray, wipe the
affected surfaces with a cloth dampened with fresh water.
Transducer Maintenance
Use the following information to maintain the transducer operation.
• If your transducer remains in the water for long periods of time, ice can
accumulate around the shaft. Check for ice buildup periodically and remove
it as needed.
• Periodically clean the face of the transducer with a cloth dampened with
fresh water.
• It may take some time to wet the transducer when it is returned to the water.
Small air bubbles can cling to the surface of the transducer and interfere with
proper operation. These bubbles dissipate with time, or you can wipe the face
of the transducer with your fingers after the transducer is in the water.
