Caution related to Equipment
Be careful of a high voltage inside.
A high voltage, which may risk your life, is used. This high voltage remains
in the circuit after you have powered off switch. To prevent touching the high
voltage circuit inadvertently, the hard cover is provided to the high voltage
circuit and the high voltage caution label is affixed. Ensure to power off
switch for your safety and discharge the electricity remaining in the capacity
before starting to check. An engineer authorized by our company should
inspect and maintain
Be sure to power off in the boat.
If the power switch is inadvertently powered on during work, you will be

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.
Caution related to 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.
In case of smoke or fire, boat power off and the power of this unit. It may
