Reset. With the many User Options available to customize the 200DX, 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 200DX are returned

to the factory settings.

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

USING THE DIAGNOSTIC FEATURE

The 200DX 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. Diagnostic can also be accessed through the Options menu.

Self Test. Initially the 200DX 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 Connection. The first connection tested is Transducer input. If a transducer is detected, the message “connected" appears. If a series of dashed lines is shown no transducer is connected or there is a problem with the transducer or cable.

If you are using multiple transducers, switch between transducers to confirm the connections for each.
