injury, and electronic shock.

●Away from direct sun light.

It causes the difficulty of future vision and heat problem.

●Be sure to use the specified power supply cable.

It causes firing and heating.

●Do not leave the power plug after its removal.

It causes firing and heating if the plug gets wet.

●Be sure to wire the cables in order for safety pilot.

The improper wiring causes the accident.

※Do not put the heavy object on cables or bend cables excessively.

be handled after landing the vessel on ground or fixing the vessel at

shipyard etc.

●Be sure to ventilate well inside the vessel when installing the

transducer at the bottom of vessel.

Volatile gas from solvent etc causes the toxic symptoms.

●Water proof treatment is required for Thru-Hull installation.

If not, it causes the marine accident.

※It is not allowed for aluminum vessels due to the risk of corrosion.

●Do not operate the electronic tools with wet hands.

It causes electronic shock.

●Do not remove the transducer plug when the power is ON.

It causes electronic shock.

●Only use with selected transducers and water temp sensors.

The use of wrong parts may cause the damage on the unit.

1-4. TFT LCD PANEL

●TFT LCD panel is made with high precision technology. Therefore, the

effective pixel is over 99％, and pixel loss and continuous lighting pixel exist

0.01％or more. Please understand the specifications.

1-5. CAUTION OF OPERATION

Battery voltage varies when the engine starts. It may cause some damage onto

the unit. Set the power OFF when starting the engine.

* Battery may go flat by operating the unit with engine off condition.
