waterline, a positive 3 will show the correct depth from the surface of the water.

Another frequent use of depth offset is to show the depth beneath the deepest point of the hull. A negative value equal to the distance from the transducer location and the deepest point of the hull will have the same effect as mounting the transducer at the deepest point.

Depth offset is remembered after power is disconnected.

Reset. With the many User Options available to customize the 450TX, it is easy to configure the unit in such a way that it is detrimental to a particular use. By using the Reset function, all variable or user-controlled features of the 450TX are returned to the factory settings.

The Reset function is an important first step in troubleshooting problems to ensure that a user selected setting is not the cause for the perceived problem.

USING THE DIAGNOSTIC

FEATURE

The 450TX contains a powerful diagnostic tool that can aid in determining the cause of a problem.

To use the Diagnostic feature, select the Diagnostic feature on the start-up menu on the initial screen.

Self Test. Initially, the 450TX will perform a self-test. This test confirms the operation of all internal circuitry. At the conclusion of the test, one of two messages will appear. “Passed” indicates the internal test discovered no failures, “Failed” indicates a significant internal problem was discovered and the unit requires factory service. A code number appears that tells repair personnel where the problem is.

Transducer. The first connection tested is Transducer input. If a transducer is detected, “Tri-Beam” or “Wide Side” appears. If a series of dashed lines is shown, no transducer is connected or there is a problem with the transducer or cable.
