0093112802-00 iii
For Your Safe Operation
Caution on location of equipment
Do not install the equipment where it is excessively damp and suffers from excessive water drops.
Escaping from static electricity
The static electricity may be generated from the carpet on the floor in the cabin or clothes made of synthetic fiber. The static electricity may destroy the electronic parts on the circuit board. Handle the circuit board, taking the measure of static electricity free.
Install the transducer at the location where it is not affected by bubble and noise The bubble and noise seriously degrade the performance of this unit.
Caution Item on Handling
Do not disassemble or modify. It may leads to trouble, fire, smoking or electric shock. In case of trouble, contact our dealer or our company.
CVS-128
In case of smoke or fire, boat power off and the power of this unit. It may cause fire, electric shock or damage.
Be cautious of remaining high voltage. A high voltage may remain in the capacitor for several minutes after you have powered off. Before inspecting inside, wait at least 5 minutes after powering off or discharge the remaining electricity in an appropriate manner. Then, start the work.
The information displayed in this unit is not provided directly for your navigation. For your navigation, be sure to see the specified material.
Use the specified fuse. If un-specified fuse is used, it may cause a fire, smoke or damage.
Whenever transmitting, be sure to submerge the transducer in water first. If transmitted without submerging the transducer, it may be damaged.

Introduction
CVS-128
Introduction
The CVS-128 is a Dual frequency (50 kHz/200 kHz) 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 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)
