3.4 Installing Scanner Unit

When you have decided the place of installation, install the scanner unit. If a mount base like the

one shown below is available, it may be easier to install the scanner. If such a mount base is not available

in your ship, you may install the scanner directly to the roof, etc. In such a case, pay attention to the

water drain tube located at the bottom of the scanner unit during installation.

Note : When the radar mast or mounting bracket has a curvature of more than 2mm, repair it or use

spacers.

Fig.3-3 Mount base

Referring to Fig.3-4, open holes in diameter of 12 mm (0.47 in.) at five locations in the mount base

and use these holes to fix the scanner unit to the mount base with hexagonal bolts. (Use the template

included with this manual.) The bolts included with your radar equipment will suffice for mount base

thickness of 9 to 14 mm (0.35 to 0.55 in.). If the mount base is thicker or thinner than this, prepare bolts

listed in Tab.3-6.
