1.  Open the antenna unit packing box carefully. 
2.  Unbolt the four bolts at the base of the radome to remove the radome cover.   

Radome cover

 
The mounting surface must be parallel with the waterline and provided with five holes (four 
fixing holes and one cable entry) whose dimensions are shown in the outline drawing 
attached at the end of this manual. 
The unit is adjusted so a target echo returned from the bow direction will be shown on the 
zero degree (heading line) position on the screen. When drilling holes, be sure they are 
parallel with the fore and aft line. 
 
3.   Prepare a platform of 5 to 10 millimeters in thickness for the antenna unit.   

A mounting bracket for mounting the antenna unit on a sailboat mast is optionally 
available. (Refer to page 1-9.) Find the cable entry on the radome base. Next, position 
the radome base so the cable entry faces the stern direction. This alignment must be as 
accurate as possible.
