WARNING
When performing maintenance work, make sure to turn off the power so that the
power supply to the equipment is completely cut off. Some equipment components
can carry electrical current even after the power switch is turned off, and thus
performing maintenance work without completely cutting off the power supply may
result in electric shock, equipment failure, or accidents.
When cleaning the touch panel display unit, do not use wax, thinner, etc. Failure to
observe this instruction may result in damage to the LCD panel surface of the touch
panel display unit.
Also, do not use chemicals, such as alcohol or antiseptic. Failure to observe this
instruction may cause change in luster or color, or color fade-out.
When reading from or writing to a file in a USB flash memory, confirm computer
viruses do not exist in the USB flash memory in advance. If the processor unit is
infected with viruses, it influences other equipment, which may cause breakdown.
Do not remove a USB flash memory while its access lamp is flashing. Data may be
damaged when the USB flash memory is inserted or removed while accessing it,
and it may cause breakdown.
When reading from or writing to a file in an external storage media, confirm
computer viruses do not exist in the external storage media in advance. If the
processor part is infected with viruses, it influences other equipment, which may
cause breakdown.
If foreign objects such as water or metal should get inside the equipment, turn off
the power switch of the equipment, turn off the main power, and then contact our
head office, or a nearby branch or local office to request servicing. Continued use of
the equipment may cause fire, electric shock, or malfunction.
If you find abnormalities, such as smoke, unusual odor, or extremely high heat
coming from the equipment, turn off the power switch and the main power supply,
and then contact our head office, or a nearby branch or local office to request
servicing. Continued use of the equipment may cause fire or electric shock.
When switching Day/Night, particularly switching to [Night], recognition of display
information may be hindered. Confirm that you can recognize display information.
Arrange and use the components of the power supply specification taking into
consideration the ship’s mains power supply.
The specification voltage of JAN - 470 series components is AC 100 V or AC 230 V.
A voltage-dropping transformer is needed in some cases, for example, for 440 VAC.
Improper arrangement or usage may cause fire or accidents.
