1. Remove four each of hex bolts (M10
u
20), flat washers and spring washers pre-
attached to the bottom of the radar sensor.
2. Using the template supplied, construct a platform and drill mounting holes in the
platform to fasten the sensor. The holes must be parallel with the fore and aft line.
3. Put the radar sensor on the platform with the bow mark ( U ) on the sensor aligned
with the ship’s bow.
4. Use hex bolts (see the table on the next page for bolt length), flat washers and
spring washers (removed at the first step) to fasten the radar sensor to the plat-
form. The torque for the bolts is 19.6 to 24.5 N•m. Apply marine sealant (local sup-
ply) to the hex bolt.

5. Connect the power/LAN cable pre-attached to the
radar sensor to the power/LAN cable. The connec-
tor pin assignment is as below.
Observe below guidelines for laying the power/LAN cable.
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.
