CAUTION
Do not exceed 18 knots when operating
the equipment and do not exceed 16
knots when lowering or raising the
transducer.
The transducer may become damaged.
The zinc block attached near the
transducer must be replaced yearly.
The junction between the transducer and
main shaft may corrode, which can result
in loss of the transducer or water leakage
inside the ship.
Do not use the equipment for other than
its intended purpose.
Use of the equipment as a stepping stool,
for example, may result in personal injury
or equipment damage.
Replace the monitor when the picture
becomes difficult to see.
The average life of the monitor is about
10 years. Replace it when the picture be-
comes difficult to see, to protect vision.
A warning label is attached to the equip-
ment. Do not remove the label. If the
label becomes soiled or illegible, contact
a FURUNO agent or dealer.
