If the unit is in thesimulator mode, make sure that the transducer is connected to the wiringharness.To test the transducer installation, gradually increase the boat speedwhile checking the unit operation. If the unit displays intermittently orfails to display, verify that the transducer is aligned parallel with the bottomand if necessary, adjust the transducer height until the unit operatescorrectly. It may be necessary to make several adjustments to ensure properoperation throughout the speed range.When adjusting the depth of the transducer, make the adjustments insmall increments. Placing the transducer too deep can adversely affectthe boat’s performance and place the transducer at greater risk ofstriking underwater objects.
