Before starting the installation work, check that the transducer casing
is of a material approved by ship classification society concerned and
with a thickness not thinner than the hull plate. The standard tank
supplied by FURUNO is of material KSTPG370（KSTPG38,KST138）, approved
by ship Classification Society of Japan, with a thickness of 25 mm.
Select the installation site reffering to the recommended sites described
in the installation instructions.
For ships prone to collect air bubbles under the hull bottom, consult
your local FURUNO office or agent for advice.
