Setting on MENU
Pic Speed
On fish finder, the newest display (display just under the boat) is shown on
the right edge of screen. At the same time previous display moves leftward.
Display of fish finder is formed by repeating such movement. Pic speed is
speed that display forwards. Display expands or reduces horizontally by
changing the pic speed.
Set Pic speed on MENU 1 or left/right arrows: 0, 1, 2, 3, 4, ×2, ×4.
Auto Range
Depth range is automatically changed so that sea bottom is always shown
on the optimum position of the screen (lower half area).
When auto range function is operating, 【DEPTH】key is non-functional.
Set Auto range on MENU 1: Off, On.
Max A-Range
It sets maximum depth when auto range is operating.
Set Max A-Range on MENU 1: 30, 100, 200, 300m,500m, 800m, Max.
Zoom
Set zoom rate in MENU 1:×2.5, ×5, ×10.
Fish Alarm
When the response to be supposed fish school is displayed and the fish
depth is above 4m, alarm goes off.
Off：fish alarm is cancelled.
Small：to catch the response form big and small fish school.
Big：to catch the response from big fish school only.
Note: Fish alarm sometimes reflects to floating matter except fish.
Set Fish Alarm on MENU 1: Off, Small, Big.

Back Ground
Reflected echo is indicated in different colors according to its strength.
Visual image of display differs from surrounding brightness. It becomes
easy to see the display by selecting different the background color.
Select Back Ground color in MENU 1: Grey, Blue, D-Blue, Black.
Pulse Width
Normally pulse width is set to short automatically according to set
displayed depth range.
Set Pulse Width on MENU 1: Short, Standard, Long.

10
TVG
This function suppresses sensitivity shallower than approx. 100m and
eliminates reflected signal form plankton and air bubble. Stronger TVG is
set, sensitivity near sea surface decreases. When you make TVG too
strong, response near sea surface disappears. On the other hand, when
you make TVG too weak, response near sea surface becomes strong and
you can not judge the image in some case.
Set TVG on MENU 1: off Low Standard High. More details see How to get steady data in page 12.
Noise Rej.
The echo interferences of the same frequency transducers nearby are
eliminated.
Set Noise Rej. on MENU 1: Off, Low, High.
Echo Color
This function facilitates clear observation by eliminate weak echo.
Set Echo Color by up/down arrows: 04 ～16.
Palette
Reflected signals of sound wave are converted into 16 ranks of digital
signals according to the strength of response. 16 ranks of color are
arranged and it is called color configuration. As image of fish finder is
displayed in colors by this color configuration, you can know the strength of
response by displayed color. As display of response varies by changing
color configuration in Palette, it enables to displayed color specially.
Set Palette in MENU 2: 0, 1, 2, 3, 4, 5.

11
Depth Alarm
Depth alarm goes off within the 3 depth ranges.
Set depth alarm on MENU 2:
Off, Upper, Zone, Lower.
Upper depth and Lower depth are set
in MENU 2: Upper limit and Lower
limit.
Upper Limit
Set Upper depth alarm value.
Set Upper Limit in MENU 2: 1m ～ (Lower Limit –10) m.
Lower Limit
Set Lower depth alarm value.
Set Lower Limit in MENU 2: (Upper Limit –10) m ～ 501m
Zone Limit
Set Zone depth alarm value.
Set Zone Limit in MENU 2: Upper Limit ～ Lower Limit.

How to get the steady data
The key to getting the steady data lies in the correct adjustment of GAIN &
Color Del..
【GAIN 1】/【GAIN 2】are used to adjust the sensitivity of signal received.
GAIN may be adjusted from the min value to max value and you can get
the appropriate sensitivity at one time point which comes before the time
point of showing littery wave on screen.
【Color Del.】: suppress unwanted echoes and noise to be adapted with
different waters environment.
Too low
Appropriate

but littery
Too high
