"Inner-hull", please select "Yes".
Press [ ] and [ ] keys in sequence, and
select "Yes".
4 Press the [MENU] key to decide the
language and the inner-hull.
5 After a few seconds, the menu sets the
screen as selected in [DISP].
Caution: In addition to English, Japanese,
there are several compatible
languages.
1.12 Display of fish information
Fish symbol detection adjustment
Detection of fish marks can be adjusted.
Select [Correct]
 [Detect adjust f].
Caution: If the larger the set values

Caution: For Thru-hull installation, adjust
between 1 and 4. For Inner-hull
installations, adjust between 3 and 6.
Size adjustment
The indicated size of fish marks can be
adjusted.
Please correct the size when the indicated
value is different from the fish that actually
caught.
Select [Correct]
 [Size adjust].
The indicated size will change by
approximately 10 to 20 percent of the value,
per one setting value.
Caution: When a set value of [Detect
adjust f] is set at 5 or 6, the size of
fish can not be specified and there
may be cases where no numerical
figures are displayed or only "----" is
displayed. When there is no display
of numerical figures, it is judged that
fish are too small. When "---" is
displayed, it is judged that fish is too
big.
Big fish / Big fish color
The fish bigger than a set value [cm] are
specified as big fish.
Select keys of [Display2]

3.6 Setting of Adjust2 Item
The visivility of the fish school echo can be
adjusted by adjusting STC.
Adjustment can be done high-frequency and
low-frequency independently.
STC strength adjust Low / High
Set smaller values for higher sensitivity.
STC depth adjust Low / High
Depth limitation of STC adjustment.
Unit: Meter
STC can be operated from 0 to the setting
depth.
Color adjustment
Rainbow pattern of the echo image can be
changed.
Set the value of each color in the range from
0 to 99%. Confirm color distribution by the
rainbow pattern of the left side of the screen.
EXAMPLE:
When the yellow value is change from 60 to
80 in the setting, the Rainbow pattern
becomes as shown below.
Image speed adjustment
The image speed can be adjusted.
The image speed becomes faster in a minus
direction, and slower in a plus direction.
Caution: Image speed cannot set faster
than the maximam speed value.
Bottom limit
The detection of sea bottom can be changed.
Sea bottom can be detected up to the range
of display multiplied by the setting value.
EXAMPLE:
Displayed 20 m, setting value: 2.0, a bottom
can be detected up to approximetery 40m.
Caution: If the setting value is increased,
the image speed becomes slower.
