MAINTENANCE AND WARRANTY

TROUBLESHOOTING / WARRANTY / SERVICE POLICY

5.The unit comes on before I press POWER, and won’t turn off.

Check the transducer cable—if the outer jacket of the cable has been cut and the cable is in contact with bare metal, you need to disconnect the cable from the unit, then repair the cut with electrical tape. If there is no problem with the cable, disconnect the transducer from the unit and see if the problem is corrected, to isolate the source of the problem.

6.I get gaps in the reading at high speeds.

Your transducer needs to be adjusted. If the transducer is transom- mounted, there are two adjustments available to you: height and running angle. Make small adjustments and run the boat at high speeds to determine the effect. It may take several tries to optimize high speed operation. This can also be a result of air or turbulence in the transducer location caused by rivets, ribs, etc.

7. My unit loses power at high speeds.

Your LEGEND 1000 SERIES has over-voltage protection that turns the unit off when input voltage exceeds 20 VDC. Some outboard motors do not regulate the power output of the engine’s alternator effectively and can produce voltage in excess of 20 volts when running at high RPMs. The LEGEND 1000 SERIES displays input voltage in the lower left corner of the display when it exceeds 15 VDC. Use this readout to determine if the voltage exceeds 20 VDC.

8.The screen begins to fade out. Images are not as sharp as normal.

Check the input voltage. The LEGEND 1000 SERIES will display the current voltage on-screen if it is greater than 16 or less than 10 VDC. The voltage readout will appear in the bottom left corner of the screen.

9.The display shows many black dots at high speeds and high sensitivity settings.

You are seeing noise or interference caused by one of several sources. Noise can be caused by other electronic devices. Turn off any nearby electronics and see if the problem goes away. Noise can also be caused by the engine. If engine noise is causing the interference, the problem will intensify at higher RPMs. Increase the engine speed with the boat stationary to isolate this cause. Propeller cavitation can appear as noise on-screen. If the transducer is mounted too close to the propeller, the turbulence generated can interfere with the sonar signal. Ensure that the transducer is mounted at least 15" (380mm) from the prop.

10.The screen does not display a full fish arch.

Check the running angle of the transducer. If the running angle is too great, a full fish arch may not appear. Reduce the running angle of the transducer. Several incremental adjustments may be necessary.
