Before You Call Customer Support
Many requests for repair received by Techsonic involve units that do not actually need repair. These units are returned “no problem found.” If you have a problem with your LEGEND 1000 SERIES, use the following troubleshooting guide before calling Customer Support or sending your unit in for repair. The LEGEND 1000 SERIES contains several tools that can aid in determining if there is a problem, as well as how to isolate and repair a problem in many cases.
1. Nothing happens when I turn the unit on.
Check the power cable connection at both ends. Be sure the cable is connected correctly to a reliable power
Check the power connection to the LEGEND 1000 SERIES. It is possible to force the power cable connector into the collector plug incorrectly. If the connector is reversed, the unit will not work. Examine the contacts on the back of the unit to ensure there is no corrosion.
Ensure the cables are properly installed into the collector plug and the collector plug is properly seated into the LEGEND 1000 SERIES.
2. The unit starts up in Simulator mode.
The LEGEND 1000 SERIES has the ability to detect that a transducer is connected. If, at power up, a transducer is not connected, the unit starts up in SIMULATOR mode.
Ensure that an appropriate transducer connector is used and the connector is positioned correctly in the collector plug. Also, be sure that the collector plug is

disconnecting the cable from both the unit and the transducer. Also, make sure that the transducer is fully submerged in water. If the transducer is connected to the unit through a switch, temporarily connect it directly to the unit and try again. If none of these items identifies an obvious problem, the transducer itself may be at fault. Be sure to include the transducer if returning the unit for repair.
To override the SIMULATOR manually, select the SIMULATOR CONTROL PANEL and turn to OFF. See Control Panels for more information.
3. There is no bottom reading visible on the display.
There are several possible causes for this condition. If the loss of bottom information occurs only at high boat speeds, the transducer needs to be adjusted. If the digital depth readout is working but there is no bottom visible
If you are using a transducer switch to connect two transducers to the LEGEND 1000 SERIES, make sure that the switch is in the correct position to connect a transducer, and that the transducer is submerged in water. (If a trolling motor transducer is selected and the trolling motor is out of the water, no sonar information will appear.)
If none of the above solves the problem, inspect the transducer cable from end to end for breaks, kinks, or cuts in the outer casing of the cable, and repair after disconnecting the cable from both the unit and the transducer. If the transducer is connected to the unit through a switch, temporarily connect it directly to the unit and try again. If none of these items identifies an obvious problem, the transducer itself may be at fault. Be sure to include the transducer if returning the unit for repair.
4.When in very shallow water, I get gaps in the bottom reading and inconsistent digital depth indications.
The LEGEND 1000 SERIES will work reliably in water 2' (.6m) or deeper. Remember that the depth is measured from the transducer, not necessarily from the surface of the water.
