Troubleshooting

Before contacting the Humminbird® Customer Resource Center, 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.

700 Series™ Doesn’t Power Up

If your 700 Series™ doesn’t power up, use the Installation Guide that also comes with it for specific confirmation details, making sure that:

•The power cable is properly connected to the 700 Series™ 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.

•The battery voltage of the power connector is at least 10 Volts.

Correct any known problems, including removing corrosion from the battery terminals or wiring, or actually replacing the battery if necessary.

700 Series™ Defaults to Simulator with a Transducer Attached

A connected and functioning transducer will cause the newly-started Fishing System to go into Normal operating mode automatically. If, when you power up the Fishing System, it goes into Simulator mode automatically, even though a transducer is already connected, this means that the control head is not detecting the transducer. Perform the following troubleshooting tasks:

•Using the Installation Guide that also comes with your Fishing System, check to make sure that the transducer cable is securely connected to the Fishing System. Reconnect if necessary, and power up the Fishing System again to see if this fixes the problem.

•Replace the non-functioning transducer with a known good transducer if available and power up the control head again.

•Check the transducer cable. Replace the transducer if the cable is damaged or corroded.
