1. Use the mounting template (supplied) to mark the location of fixing holes in the
mounting platform. Be sure to drill the holes parallel with the bow.
2. From the bottom of the radome, remove flat washers (M12), spring washers
(M10), flat washers (M10) and hex head bolts (M10
u
20).
3. Lay the antenna unit on the mounting platform with the bow mark (
U
) on the an-
tenna unit facing the bow.
4. Use hex bolts*, flat washers and spring washers (removed at step 1) to fasten the
radar sensor to the platform. The torque for the bolts must be 19.6 to 24.5 Nm.
Apply marine sealant (local supply) to the hex bolt, flat washers and spring wash-
ers as shown below. * See the figure and table below to determine the bolt length
to use.

5. Connect the power/LAN cable from the radar sensor
to the ship’s power/LAN cable. The connector pin ar-
rangement is as shown to the right.
Observe below guidelines for laying the power/LAN cable.
• The connectors must not strike any part of the vessel by wind, etc.
• The load applied to the connectors must not be more than the power/LAN cable.
• If the cable is passed through a mast on a sailboat, be sure the cable does not
touch ropes (sheet, halyard, etc.).
• Do not fasten the cable to the hull.
