Section 5: Troubleshooting

If your unit is not working, or if you need technical help, please use the following troubleshooting section before contacting the factory customer service department. It may save you the trouble of returning your unit for repair. For contact information, refer to the last page, just inside the back cover of this manual.

Unit won't turn on:

1.Check the power cable's connection at the unit. Also check the wir- ing.

2.Make certain the power cable is wired properly. The red wire con- nects to the positive battery terminal, black to negative or ground.

3.Check the fuse.

4.Measure the battery voltage at the unit's power connector. It should be at least 11 volts. If it isn't, the wiring to the unit is defective, the battery terminals or wiring on the terminals are corroded, or the bat- tery needs charging.

Unit operates only in demo mode:

1.The transducer has not yet been connected or has been disconnected. To leave demo mode, make sure the transducer is securely connected before turning the unit on.

Unit freezes, locks up, or operates erratically:

1.Electrical noise from the boat's motor, trolling motor, or an accessory may be interfering with the sonar unit. Rerouting the power and trans- ducer cables away from other electrical wiring on the boat may help. Route the sonar unit's power cable directly to the battery instead of through a fuse block or ignition switch

2.Inspect the transducer cable for breaks, cuts, or pinched wires.

3.Check both the transducer and power connectors. Make certain both are securely plugged in to the unit.
