Do not open the equipment
unless totally familiar with
electrical circuits and
service manual.
Only qualified personnel
should work inside the
equipment.
Turn off the power at the switchboard
before beginning the installation.
Fire or electrical shock can result if the
power is left on.
Do not install the equipment where it
may get wet from rain or water splash.
Water in the equipment can result in fire,
electrical shock or damage to the equipment.
WARNING
Install the transducer tank according
to the installation instructions.
Failure to install the tank correctly may
result in water leakage and damage to
the ship's hull.
Be sure no water leaks in at the transducer mounting location.
Water leakage can sink the vessel. Also,
confirm that the transducer will not loosen
by ship's vibration. The installer of the
equipment is solely responsible for the
proper installation of the equipment.
FURUNO will assume no responsibility for
any damage associated with improper
installation.
Be sure that the power supply is
compatible with the voltage rating of
the equipment.
Connection of an incorrect power supply
can cause fire or damage the equipment.
Do not diassemble or modify the
equipment.
Electrical shock, damage to the equipment
or injury may result.

Do not allow warm water or any liquid
other than seawater or freshwater to
contact the transducer.
Damage to the transducer may result.
Do not install the transducer where
noise or air bubbles is present.
Performance will be affected.
The transducer cable must be handled
carefully, following the guidelines
below.
• Keep fuels and oils away from the
cable.
• Locate the cable where it will not be
damaged.
• The cable sheath is made of chloro phrene or polychloride vinyl, which
is easily damaged by plastic solvents
such as toulene. Locate the cable
well away from plastic solvents.
Use the correct fuse.
Use of a wrong fuse can cause serious
damage to the equipment.
Be sure to enter transducer model
correctly.
Incorrect setting may damage the
transducer.
Do not enter transducer type manually
if the transducer type is programmed
into the equipment.
Damage to the transducer may result.
WARNING LABEL
A warning label is attached to the equipment. Do not remove the label. If the
label is missing or illegible, contact
a FURUNO agent or dealer about
replacement.
WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
