This device complies with Part 15 of the FCC Rules and European RED Directive 2014/53/EU. Operation is subject to the condition that this device does not cause harmful interference.
Do not run the feedback cable parallel to high-current wiring, such as radar cables, VHF antenna coax, or thruster power lines.
The RF300 must be mounted upside down or right-side up so that its arm moves in the exact same horizontal plane as the rudder tiller arm. simrad rf300 installation manual
The successful installation of the Simrad RF300 is predicated on precise mechanical alignment and correct electrical interfacing. As the primary sensor for vessel heading control, the integrity of the RF300 installation directly correlates to the performance and safety of the autopilot system. By adhering to the procedures outlined in this paper—specifically regarding the parallel mounting geometry and travel limit settings—marine technicians can ensure reliable feedback and extend the operational life of the equipment.
The RF300 requires almost zero maintenance if installed correctly. However, the mechanical linkage (ball joints and rod ends) will wear over time. Every 12 months, check the linkage for rust or play. Apply a light marine-grade grease to the ball joints to prevent seizing, but ensure no grease gets into the sealed RF300 housing itself.
Ensure the rod does not bind or hit any obstructions as the rudder moves from hard-over to hard-over. 4. Electrical Installation and Wiring : (hypothetical – refer to product label) IC
If you must cross power cables, cross them at a 90-degree angle.
If your autopilot screen displays a "Rudder Feedback Failure" alarm or shows erratic behavior, use these diagnostic steps:
Mark the two mounting holes, drill pilot holes, and secure the RF300 base using the provided stainless steel screws. The RF300 must be mounted upside down or

To perform a standard installation, the following tools are required:
Check: Inspect the mechanical ball joints for slack, play, or looseness. Even 1mm of physical play can cause the pilot to over-correct continuously.
Once installed, the unit must be configured through your Simrad Control Unit or Multifunction Display (MFD). B&G RF300 Rudder Feedback Unit - Simrad Commercial
Adjust the length of the threaded transmission rod so that it fits perfectly between both ball joints while both the rudder and the RF300 remain perfectly centered.
