Scanner unit assembling

The scanner radiator and the scanner housing are shipped in separate packages and must be assembled at installation. Assemble them as below. Refer to the scanner unit assembling drawing at the back of this manual for details.

1.Remove two protective caps from the radiator flange and rotary joint flange.

2.Grease an O-ring and place it in the groove of the rotary joint flange. Make sure the O-ring is not pinched during assembling.

3.Secure the feeder waveguide to the rotary joint flange with four M6x16 hex bolts.

4.Fix the feeder waveguide on the radiator joint with four M4x16 washer head bolts. Coat waveguide flange with silicone sealant as illustrated below.

5.Loosely fix the radiator to the radiator bracket with M8x25 and M8x30 hex head bolts, M8 flat washers, M8 spring washers, and M8 hex nuts.

6.Grease the other O-ring and place it in the groove of the radiator flange. Secure the feeder waveguide to the radiator flange with M4x16 washer head bolts.

7.Fix the feeder waveguide to the bottom of the radiator with the waveguide clamp, waveguide packing, M4x30 hex head bolts, M4 flat washers, and M4 spring washers.

8.Tighten bolts loosely fixed at step 5.

Moreover, the FR-2155 incorporates an Automatic Radar Plotting Aid (ARPA) function that automatically tracks up to 50 targets, allowing operators to concentrate on navigating rather than manually monitoring multiple targets.

Another remarkable characteristic of the Furuno FR-2155 is its ability to operate in various weather conditions. The radar system can filter out rain, sea clutter, and other interference, ensuring a clear image of surrounding objects. This feature is especially beneficial in adverse weather, where visibility is often compromised, thereby enhancing safety during challenging navigation scenarios.

Connectivity is crucial in modern maritime operations, and the FR-2155 excels in this regard by offering various integration options for onboard systems. It can seamlessly connect with GPS, AIS, and other navigation systems, providing a comprehensive overview of the vessel's environment. Additionally, the radar is capable of outputting data to chart plotters and electronic displays, consolidating critical information for the crew.

In terms of installation, the Furuno FR-2155 is designed for versatility. Its compact design allows for flexible mounting options, accommodating different vessel layouts without compromising performance. The radar also features a powerful magnetron that ensures long-range detection capabilities, effectively covering vast areas of water.

In summary, the Furuno FR-2155 marine radar system stands out due to its high-definition display, Doppler technology, automatic target tracking, and excellent clutter rejection. Its ability to integrate seamlessly with other navigation tools and its user-friendly design make it an invaluable asset for any vessel, ensuring safety and efficiency on the water. For those looking for a reliable radar solution, the FR-2155 is certainly worth considering.
