10 GPSMAP 400/500 Series Installation Instructions
To test the transom mount transducer installation:
1. Begin testing the installation at a slow speed. If the sonar appears to be working properly, gradually increase the speed of the boat while
observing the operation of the sonar. If the sonar signal suddenly is lost or the bottom return is severely degraded, note the speed at which
this occurs.
2. Return the boat to the speed at which the signal was lost. Make moderate turns in both directions to see if the signal improves.

in. below the transom of the boat. It might
take several adjustments to eliminate the degradation.
4. If the signal does not improve, you might have to move the transducer to a different location.
When adjusting the depth of the transducer, make the adjustments in small increments. Placing the transducer too deep can adversely affect
the performance of the boat and put the transducer at greater risk of striking underwater objects.
