SAFETY INSTRUCTIONS
WARNING
ELECTRICAL SHOCK HAZARD
Do not open the equipment.
Only qualified personnel
should work inside the
equipment.
Immediately turn off the power at the
switchboard if water leaks into the
equipment or an object is dropped into
the equipment.
Continued use of the equipment can cause
fire or electrical shock. Contact a FURUNO
agent for service.
Do not place liquid-filled containers on
the top of the equipment.
Fire or electrical shock can result if the
liquid spills into the equipment.
Do not disassemble or modify the
equipment.
Fire, electrical shock or serious injury can
result.
Keep the equipment away from rain
and water splash.
Fire or electrical shock can result if the
rain or water gets into the equipment.
Do not operate the equipment with wet
hands.
Electrical shock can result.
Keep heater away from equipment.
A heater can melt the equipment's power
cord, which can cause fire or electrical
shock.
Use the proper fuse.
Fuse rating is shown on the equipment.
Use of a wrong fuse can result in damage
to the equipment.
Do not use the equipment for other than
its intended purpose.
Improper use of the equipment can result
in personal injury or equipment damage.
Turn off the equipment immediately if
you feel it is abnormal.
Turn off the power from the switchboard if
the equipment is emitting strange noises
or becomes excessively hot. Contact your
dealer for advice.
The useable ambient temperature range
is 15°C
to 55°C.
Do not use the equipment out of the
above temperature range.
Do not place objects around the
equipment.
Overheating may result.
Do not power the equipment when the
transducer is in air.
The transducer may become damaged.
Handle all units carefully.
Damage can lead to corrosion.
Do not use chemical cleaners such as
alcohol, acetone and benzine to clean
the equipment.
Chemical cleaners can remove paint and
markings. Use only a soft, dry cloth. For
stubborn dirt, use a soft cloth moistened
with water-diluted mild detergent.
When dry docked remove marine life
from the transducer.
Remove marine life to maintain good
sensitivity.
Do not paint the transducer face.
Further, handle the transducer with
care.
Paint will affect equipment performance.
CAUTION

WARNING LABEL
A warning label is attached to the
units shown right. Do not remove the
labels. If a label is missing or is illegible,
contacta FURUNO dealer or agent about
replacement.
