Introduction
The CVS-128/128B is a Dual frequency Color LCD display echo sounder.
This unit equipped with digital process displays the circumstance in the water under all conditions, matching with the high luminance 8.4 inch LCD.
The main features of this unit are as follows:
With the digital reception process, the compatibility of the high resolution in a shallow depth and the noise rejection capability in a deep depth are established. The auto mode function provides the best image.
The high-performance LCD maintains high visibility under any conditions.
The unit can be installed in an open bridge and is highly waterproof.
Sona-Tone (Sonar sound) function is equipped with for catching situations schools of fish and others by sound.
Up to 10 images can be stored. If you connect the optional GPS, the fishing hot spot function, that directs your boat to navigate easily to the location desired, is available by marking the event mark when recalling the stored image.
With the adoption of a specific filter (AR coat), an image can be seen clearly, refusing sunshine.
The countermeasures against the reflection on the LCD screen and dew are provided.
The various alarm functions are available. (Bottom, school of fish, water temperature*, boat speed*, arrival*, XTE*, power) (Note: The mark * denotes that the connection of option is mandatory)
When flush-mounting, the unit can be easily installed from front side.
The RGB output for an external monitor is provided as standard equipment. The use of the external monitor enables you to observe easily the echo sounder screen at a location which is remote from a main unit. (External monitor: Prepared by a customer)
CVS-128B is the high sensitivity model with broadband transducer. This model can be used at your optimum frequencies within the specification of the broadband transducer. You can set 2 frequencies depending on a target fish or intended purpose during operation.

1.12 Display of fish information
When transducer TD-501C is connected, specific response can be displayed as [Fish symbol].
For detection of fish information, 2 frequencies,
200 kHz and 50 kHz are used.
Only in case echo comes up in both frequencies, the detection can be made.
By [Symbol info], the magnitude and the value of depth of the response can be displayed.
Caution: Fish information is to display the specific responses in an easy way to watch. Displays of [Fish symbol] do not always mean that there is fish there.

Caution: If the larger the set values become, the more fish marks can be displayed with more false detections.
Caution: For Through-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.
CVS-128/128B
Caution: When the 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.

Chapter 1 Basic Operation
Points to note in use of fish symbol
The values displayed by this function may be incorrect depending on various environmental conditions. In use of these values, please understand the following factors of error, and use them as reference:
[Factors of error]
1
When there are overlapping responses, all of them may be displayed to show the magnitude of a point.
2
The strength of reflection may depend on the output of transducer unit and may result in a factor of error.
3
The strength of reflection may depend on the kind of fish and may result in a factor of error. As for the fish such as the squid which don't have an air bladder, the error is big.
4
Fish banks, fishing net, fishing equipment, air bubbles and floating objects, etc. may be detected and displayed.
5
When the transducer unit is mounted in inner-hull, there may be cases where response cannot be detected depending on attenuation, and large error may be generated.
6
The strength of reflection may depend on the difference of ship handling such as stoppage and cruising, and may result in a factor of error.
7
Each transducer unit may have difference in transmission/receiving performance to cause error.
8
When there is dirt in the sea and the plankton layers have been generated, it becomes the factor of the error margin.

[Fish alarm] issues the alarm when an echo recognized as school of fish exists in the set range. It is convenient for you to judge whether the echo of school of fish is present or not.
(Setting: m: 1 to 800, fm, I.fm: 1 to 700, ft: 1 to
2800)
Caution: In the [Level], select the strength of echo reflected from the schools of fish in the [Fish alarm].
[Water temp alarm] issues when the water temp is within or out of the set range. It is convenient to keep the specific water temp region. (Setting:
- 5 to 45 ºC, 23 to 113 ºF)
[Speed alarm] issues when the boat speed is faster or slower than the set range. It is convenient when the speed limit is obliged.
(Setting: 0 to 80 kn, 0 to 148 km/h)
[Arrival alarm] can be used in the state that the destination is set. The alarm is issued when your boat arrives within a certain range of destination.
A certain range is set in the [NAV alarm range].
(See [1.9 Use of [EVENT] key.)
[XTE alarm] can be used in the state that the destination is set. The alarm is issued when your boat is off a certain distance from the course on the line drawn straightly from destination to the location when setting the destination. A certain distance is set in the [NAV alarm range].
Caution: In the [NAV alarm range], select the alarm range of [Arrival alarm] and [XTE alarm]. (Setting: 5 to 999 m)

Gain (TD)
5
Press the [MENU] key to close the menu.
Caution: Gain (TD) setting value widely varies upon installation conditions such as material of hull and installation method. Low frequency
(50 kHz) may not be used due to large signal attenuation in some cases.
TVG
The TVG adjusts the difference of strength between echoes reflected from the shallower depth and echoes reflected from deeper depth so that the reflection can be uniformed.
The deeper the depth is, the weaker the reflected signal of echo sounder becomes due to attenuation. Thus, comparing the signal reflected from the fish of the same size, the signal reflected from the fish in the shallower depth is stronger than that in the deeper depth.
The TVG adjusts the echo signal reflected from the shallower depth to be equal to that reflected from deeper depth by decreasing the receiver gain so that the effect that the strength of echo signal reflected from the shallower depth looks the same as that reflected from the deeper depth provided. The level of adjustment due to the depth increases in the order of weak → medium → strong. When set to "Strong", the
TVG provides strongest effect that reduces various noises around oscillation line.

Bubble time set
While auto-range or auto-shift is in use, and if the missing image is caused by bubble, range and shift continues changes until sea bottom is detected by auto mode.
Setting the bubble time duration holds the range or shift at the level when bubble started.
If bubble disappears and sea bottom is detected, range or shift returns to auto mode.
This makes the time shorter until the image comes back to normal. After the specified time, the mode returns to the previous auto-range or auto-shift. (Setting: OFF, 1minutes to 10minutes)

Figure 5.6 Installation of Transducer
In case of Inner-hull
Using the optional inner-hull kit (MFB-04), install the transducer to the inner side of ship’s bottom.
Caution on installation
Figure 5.7 Inner-Hull installation
(1) Select the location where no bubble is generated during navigation.
(2) Select the relatively thin location of ship’s bottom.
(3) Be sure to remove oil on the contact surface. File the contact surface with sand paper (#400) so that the adhesive strength will increase.
(4) The adhered surface will dry in about two hours.
(5) Leave the unit for a whole day and fill in the coolant. More than 80 % of the transducer should be submerged in the coolant.
Caution: It is strongly recommended to confirm the location of the installation of Inner-hull with the ship manufacturer. The Inner-hull device is more simplified method. The gain falls dramatically in comparison with the Through-hull performance. Low frequency (50 kHz) may not be used due to large signal attenuation in some cases. Depth range performance using 200 kHz Transducer in case of Inner-hull can be less about 50% than that of Through-hull.
Caution: Fishing boats may have structure with FRP contained air bubbles and foamed materials that would prevent ultrasound from penetration. Therefore, the location convenient for installation may not be locations where attenuation of ultrasound is low enough.
CVS-128/128B Chapter 5 Installation
In case of Through hull
Install the transducer directly to the ship’s bottom
Installation Procedure
(1) Select the installing location.
(2) Remove the fixing nut and one piece of rubber packing.
(3) If the slope of ship’s bottom is greater than 5°, make a wooden base to fit to the slope of ship’s bottom. To reduce the water resistance, cut the bow direction tip of wooden base at the outer side of ship’s bottom in the triangle shape.
(4) Make holes at the installing location. If the wooden base is used, make holes in the wooden base.
(5) Thread the rubber packing in the transducer and then the cable.
(6) To prevent water from seeping through the gap between the transducer and the hole, fill out the gap with FRP or silicon glue. (Glue the wooden base likewise.)
(7) Thread the rubber packing and fix it with the fixing nut firmly.
(8) Connect the transducer cable to the connector of Display unit.
