Follow the precautions below for optimal
product performance and to reduce the risk of
property damage, personal injury, and/or death.
WARNING
: Always wear safety glasses, a dust mask,
and ear protection when installing.
WARNING
: Use marine sealant to seal the hull and hold
the transducer firmly in place.The bolts are an aid to
installation only and must not be solely relied upon.
When the boat is underway, especially at high speeds,
water will enter any gaps and push against the
transducer with considerable force.
WARNING
: Immediately check for leaks when the boat is
placed in the water. Do not leave the boat unchecked for
more than three hours. Even a small leak may allow
considerable water to accumulate.
CAUTION
: Do not install in the engine compartment or
other hot place. The transducer may fail if it overheats.
CAUTION
: Always operate the transducer in water.
Operating in air will allow the transducer to overheat
resulting in failure.
CAUTION
: The transducer must be flush with the bottom
of the hull for good performance.
CAUTION
: Never install a metal housing on a vessel with
a positive ground system.
CAUTION
: Never mount a bronze transducer in a metal
hull, because electrolytic corrosion will occur.
CAUTION
: Never pull, carry, or hold the transducer by
the cable. This may sever internal connections.
CAUTION
: Never strike the transducer.
CAUTION
: Never use solvents. Cleaners, fuel, sealant,
paint and other products may contain solvents that can
damage plastic parts, especially the transducer’s face.
IMPORTANT
: Please read the instructions completely
before proceeding with the installation. These
instructions supersede any other instructions in your
instrument manual if they differ.
