Transducer Level (L) and
Keel / Depth Offset
On installation the depth displayed is from the transducer.
Normally the transducer is mounted at some distance above
the bottom of the keel. If this distance is entered as a
positive (+) number, (
Keel Offset) the display will show
the depth below the keel. The transducer is also mounted
below the water line. If this distance is entered as a
negative (-) number, (
Depth Offset) the display will show
depth from the waterline.
The
SE-200 also includes an adjustments to compensate for
some transducer installation problems, especially thru-hull
installations, where the transducer’s stem is not perfectly
vertical to the water’s surface. This problem can be caused
by improper installation, or by changes in the boats fore/aft
weight.
When the boat is over a known level bottom, the forward
vertical (
VERT) scan display should show a level line. If
the bottom display is slanted upward or downward (as in the
pictures at left), note the approximate angle of the
unwanted upward or downward slope on the display. Then
proceed to the
TRANSDUCER adjustment menu, as
above, and press the
softkey buttons to adjust the
Level (L). It is possible to /- 15 degrees. Positive
numbers will tend to make the bottom slope upwards and
negative numbers will make the bottom slope downwards.
After making the adjustment, go to the forward vertical
display and verify the correction. Once adjusted, the
SE-
200’s memory will retain the setting.
Demo
If the
DEMO softkey is pressed the SE-200 will go into a
demonstration mode where simulated data is sent to the
display. This mode can be a useful tool to help understand
the operation of the unit. To exit the
DEMO mode, press
the
DEMO softkey again.
System Reset
The
SE-200 remembers most setting when it is turned off.
Normally this is good, however sometimes it can cause
problems and you may want to do a reset on the machine to
restore it to the factory defaults. To do this, turn the unit on
while simultaneously pressing both the
CURSR and PWR
buttons.
