accuracy. Remember, the speed paddle wheel measures speed through the
water, not speed over ground.
Speed offset is remembered after power is disconnected.
Depth Offset. The Depth Offset allows the user to select
the point on the boat from which the depth
measurement is made. Selecting a positive value adds
distance to the measurement. If the transducer is
mounted 1 metre beneath the waterline, a positive 1 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 425SX, 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 425SX 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 425SX 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.
