CVS-126 Introduction

Introduction

The CVS-126 is a Dual frequency (50kHz/200kHz) 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 5.7 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 unit can be installed in an open bridge and is highly waterproof.

• Up to 10 images can be stored. If you connect the optional GPS, the homing function, that directs

your boat to navigate easily to the location desired, is available by marking the event mark when recalling the stored image.

• The unit is designed to save power consumption. The white LED is adopted for illuminating the LCD and the power consumption is minimal in this class. The unit emits less heat and the occurrence of condensation is rare.

• 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.

2.182.18 Item

The various items in the menu are explained.

TVG

The TVG corrects the difference of strength between echo reflected from the shallow depth and echo reflected from deep 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 with the signal reflected from the same size fish in the shallow depth, the signal reflected from the fish in the deep depth becomes weak. The TVG corrects the echo signal reflected from the deep depth to be equal to that reflected from shallow depth by increasing the receiver gain so that the effect that the strength of echo signal reflected from the deep depth looks same as that reflected from the shallow depth provided. The correction gain due to the depth increases in the order of weak → medium → strong. When set to “weak”, the TVG also provides the effect that reduces noise in the shallow depth.

Select the [Adjust] → [TVG].

Caution: When set to [OFF], the built-in

speaker does not output the sonar. When set to [ON], the built-in speaker outputs the sonar.

Press the 【MENU】 key to close the menu.

Connection of External Speaker

Connect the external speaker with amplifier (option) so that you can hear the sonar easily.

The sonar is always outputted. Adjust the speaker volume with the volume provided on the speaker.

Caution: The external speaker is an option.

Select the [weak, medium, strong].

TVG

Change the TX power.

The strength of transmission output (power) can be changed.

When the noise of interference with the neighboring echo sounder occurs, if the powers of transmission outputs at both sides are weakened, the interference noise can be suppressed.

In the [Auto] setting, the transmission output is automatically adjusted.
