1. Open the packing box of the antenna unit with great caution.
2. Loosen the four bolts at the base of the radome to remove the radome cover.

The location where you install the antenna unit must be parallel to the waterline. Make five
holes in the installation location. See the outline drawing at the end of this manual for dimen-
sions. A target echo returned from the bow direction must be shown on the zero degree posi-
tion on the screen. When you make holes, make sure the holes are parallel to the fore-and-aft
line.
3. Prepare a platform of 5 to 10 millimeters in thickness for the antenna unit.
The optional mounting bracket lets you install the antenna unit on a sailboat mast. (Refer to
page 1-8 for information.) Find the cable entry on the radome base. Set the radome base so
that the cable entry is toward the stern.
