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: OFF, 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, 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 length is set to short automatically according to set
displayed depth range.
Set Pulse Width in MENU 1: Short, Long.

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: 0 ～ 40. More details refer to 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.
Color Del
This function facilitates clear observation by eliminate weak echo.
Set Color Del on MENU 2: 0 ～ -12.
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 ～ 6.

in MENU 2: Shallow Set, Deep Set.
Shallow Set
Set shallow depth alarm value.
Set Shallow Set in MENU 2: 1m ～ 50m.
Deep Set
Set deep depth alarm value.
Set Deep Set in MENU 2: 16 m ～ 501m.

WaterTemp Al
Water temperature alarm goes off within 3 temperature ranges.
Set WaterTemp Al on MENU 2:
Off, Low, Midd, High.
Low set and High Set are set in MENU 2:
Low Set, High Set.
Low Set
Set low alarm temperature value.
Set Low Set temperature value in MENU 2: 0℃ ～ High Set Value – 1 ℃.
High Set
Set high alarm temperature value.
Set Low Set temperature value in MENU 2: 1℃ ～ Low Set Value + 1 ℃.

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 one and you can get the
appropriate sensitivity at one time point which comes before the time point
of showing littery wave on screen.
【TVG】: suppress unwanted echoes and noise to be adapted with different
waters environment.
