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
405SX, 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
405SX 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 405SX 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 of
the initial screen.
Self Test. Initially, the 405SX 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.
