3.Now is the time to fix the radiator to the radiator bracket. Apply anticorrosive seal- ant (silicone sealant) to hatched areas, to prevent corrosion. See the figure below. Apply silicone sealant into threaded holes on the scanner radiator. Remove the cap on the radiator bracket and orient the ra- diator bracket as shown in Figure 6-13. Apply grease to the O-ring and set it to the center of the radiator bracket. Coat the ra- diator fixing bolts with silicone sealant. Fasten the radiator to the radiator bracket with the FURUNO logo on the radiator fac- ing ship’s bow.

4.Open the antenna housing cover and fix the stay as shown in Figure 6-19.

5.One end of the cable with 15-, 9- and 7- way plugs has already been connected to RTB-9100 inside the scanner housing. Mate the 15- and 9-way plugs with jacks J812 and J811 on the transceiver module, respectively. Connect the 7-way plug to jack J701 on the MP Board. Secure the cable between RTB-9100 and J701 with the cable tie as shown in Figure 6-19.
