Safety Instructions for the Operator
WARNING
ELECTRICAL SHOCK HAZARD
Do not open the equipment.
Only qualified personnel
should work inside the
equipment.
Do not disassemble or modify the
equipment.
Fire, electrical shock or serious injury can
result.
Immediately turn off the power at the
switchboard if the equipment is emitting
smoke or fire.
Continued use can cause fatal damage to
the equipment. Contact a FURUNO agent
for service.
Do not place liquid-filled containers on
the top of the processor unit.
Fire or electrical shock may result if the
liquid enters the equipment.
Use the proper fuse.
Use of a wrong fuse can damage the
equipment and cause fire.
CAUTION
No one navigation device should ever
be solely replied upon for the navigation
of a vessel.
Always confirm position against all avail-
able aids to navigation (incl. nautical charts),
for safety of vessel and crew.
Safety Instructions for the Installer
