Precautions for transporting and storing the scanner
A scanner is a heavy load. Be very careful about handling it.
Do not allow the scanner fall on its side while it is stored or being installed.
Do not apply rope to the scanner in the way that squeezes or deforms the radiating section.
When hoisting the scanner by a crane, do not hoist it by attaching a belt or a rope only to the
scanner's radiating section as shown in Fig1-3-6-9.
When lifting the scanner (Fig 1-3-6-10) :
Wrap a cloth around the scanner's support section located at the bottom of the radiator, and
then attach a belt to it to lift the scanner.

Installation and clamping method
Installation direction
Installation should be done so that the cable gland is oriented toward the stern.
Bolts, nuts and tightening torque to be used
Use stainless steel bolts for the scanner and uniformly tighten all of the bolts using double
nuts for each bolt so that the scanner will not become loose (Table 1-3-6-1).
Although the length of the bolt will differ according to the thickness of the mount base, use a
bolt long enough so that more than 4 millimeters of thread protrudes beyond the double nuts
after the double nuts have been tightened.
