or other persons from human damage or damage to their property.
1. HANDLING OF MAIN UNIT

● High voltage is applied to the inside of unit.
No one besides authorized technician should disassemble or modify it.
Unless you keep it, the accident resulting in the electric shock will occur.
※ Please be sure to consult with dealer when you want to repair.
● Do not install it in simple method.
It causes to the accident like human damage.
※ Please be sure to install correctly according to descriptions on "Installation of the unit" of
this manual.
● Do not use the information displayed on the screen of unit for navigation directly. It causes
to the marine disaster.
※ Please be sure to use the ofcial marine charts for navigation judgment.
● Do not put the power on in the presence of ammable materials.
It causes to ring.
● Do not use the power supply besides the specied ones.
It causes to heating or ring.

2. HANDLING OF CABLES
● Be sure to use the specied power supply cable and fuse.
It cause to heating or ring.
● Do not leave the power plug as it is while it is pulled out of the unit.
If the plug gets wet, it causes to heating or ring due to short circuited.
● Be sure to wire in order to prevent the cables from interfering to operate boat.
If feet of crews or operating equipments are caught in cables, it causes to theaccident.
※ Do not put the heavy objects on cables or do not bend cables excessively.
● Do not disassemble or modify the cables.
It causes to heating, ring or electric shock.
● Do not use the damaged cables.
It causes to ring or electric shock.
● Do not pull the cable when you pull out the plug.
It causes to ring or electric shock because the cable is broken.
※ When you pull out the plug, be sure to have it in your hand and pull it.
3. HANDLING OF TRANSDUCER AND WATER TEMPERATURE SENSOR
● Work on the board is too unstable and risky.
Installation and maintenance of transducer and water temperature sensor
should be done after you land and x the boat.
Unless you keep it, human damage resulting in death or serious wound will occur.
※ Please ask to shop for installation.
● Installation of the transducer or water temperature sensor inside the hull with adhesive
should be done while you ventilate well inside the boat.
Volatile gas from solvent or etc. causes to toxic symptoms.
● When you work using electric tools, please keep your hands dry.
If you hands are wet, it causes to electric shock.
● When you pull out or insert the plug of transducer or water temperature sensor, please be
sure to turn the power switch off.
It causes to electric shock.
● Perfect waterproof treatment should be done when you install the transducer or water
temperature sensor through the hull.
If waterproof is not sufcient, it causes to marine disaster because water comes in.
※ Please ask to shop for installation.

2. Power supply should be 11-35VDC!
Please make sure to operate the unit at 11-35VDC of power supply voltage.
3. Avoid the place where it is high temperature!
When temperature of the unit exceeds 70˚C, it causes to faulty. Please be more careful to
operate or store it under direct sun ray in the summer time and use it carefully where it is in
the shade as possible.
4. Prohibited to use the organic solution!
Do not clean the unit with organic solution like thinner, alcohol or etc. as some parts of the
unit and panel are coated or made by plastic. In case it is too dirty, soak the soft cloth in a
synthetic detergent and clean with it after wringing well.
5. Be careful for water-spray!
Water-spray on the unit causes to faulty, install at the place where there is no water-spray.
FEATURES

LCD
● Bottom lock expansion function as well as bottom
expansion (Auto, Manual) are incorporated.
● Beginners can operate without worry using Auto Range
Control and Auto Gain Control.
● You can install the display in both width and length as well
as you can change the display Portrait or Landscape.
● You can install at any place using compact and light case.

This describes operation for single frequency display.
※ You can change sensitivity by GAIN1 key or GAIN2 key.
※ Single frequency display or dual frequency display is selected on menu. ( → page 20 )
※ When the unit is delivered from factory, dual frequency display mode is set.
[Gain]
This adjusts the sensitivity to distinguish the bottom or sh school easily. 32 steps of sensitivity
from 0 to 31 is displayed in bar. Optimum sensitivity is that second reection from bottom is
barely displayed.
[Second reection]
First received echo reected from bottom is called the rst reection. It's rst reection reected
from the surface of water goes toward the bottom again. The next reection from bottom is
called the second reection. Normally, it's second reection is shown on the twice depth of the
actual bottom (rst reection).
1 [To decrease sensitivity]
Each time when you press GAIN1 key, gain bar
becomes short and the sensitivity decreases.
2 [To increase sensitivity]
Each time when you press GAIN1 key, gain bar
becomes long and the sensitivity increases.
