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 board 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*, board 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)

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】】】】

fish symbol

When there are overlapping responses, all of them may be displayed to show the magnitude of a point.

The strength of reflection may depend on the output of transducer unit and may result in a factor of error.

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.

Fish banks, fishing net, fishing equipment, air bubbles and floating objects, etc. may be detected and displayed.

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.

Chapter 1 Basic Operation

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.

Each transducer unit may have difference in transmission/receiving performance to cause error.

2.18 Explanation of Menu Item

The various items in the menu are explained.

Inner-hull

The reduction in sensitivity due to signal attenuation in inner-hull use can be corrected. (Setting: - 50 ~ 50: through-hull: 0)

Press the [MENU] key.

Select the [Adjust] → [Gain (TD)]. (See [2.1 How to operate the menu])

Press the [ ] key. The image displays bottom only. It may show very strong fish targets.

Set a value to display the sea bottom continuously without interruption. For high frequency, turn [GAIN (HF) knob] and for low frequency, turn [GAIN (LF) knob].

Press the [MENU] key to close the menu.

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 reflected signal of echo sounder becomes weaker due to attenuation. Thus, comparing with the signal reflected from the same size fish, 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.

Press the [MENU] key.

Gain (TD) L

Gain (TD) H

Gain (TD)

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.

5.3 Installation of Transducer

The standard installation of this echo sounder is shown in figure 5.6.

Figure 5.6 Installation of Transducer

CVS-128

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

(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.

Figure 5.7 Inner-Hull installation

Caution: Confirm a place of the installation of inner-hull in the manufacturer of the ship

and so on. The inner-hull device is for more effective performance method. The gain falls in comparison with the through-hull performance dramatically. Low frequency (50 kHz) may not be used due to large signal attenuation. Depth range performance using 200 kHz Transducer in case of inner-hull will also be less about 50% than that of through-hull.

Caution: In the case of fishing boats, FRP contained air bubbles and foarmed materials

that would prevent ultrasound from penetration have been likely used. Therefore, even locations that are convenient for installation may be locations where attenuation of ultrasound is not low enough.

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 CVS-128 Display unit.
