Save the calibration settings and return to the main operational screen. 3. Verification Test

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

The is a high-precision rudder feedback unit designed to ensure smooth, accurate auto-steering for boats with inboard engines. It operates by measuring the rudder's angle and transmitting a variable frequency signal directly to an autopilot computer. Key Features

When turning hard-to-port or hard-to-starboard, the frequency should smoothly scale up or down between roughly 2500 Hz and 4300 Hz. If the frequency stays locked at zero or doesn't change when the arm rotates, the internal electronics of the RF300 are damaged and the unit needs replacement.

Measure the actual physical angle of the rudder if possible, or use the default max angle specified by your vessel's manufacturer (typically 35 degrees). Verification Test Ensure the rod does not bind

If a rudder feedback alarm occurs, check the mechanical alignment (Step 3) to ensure the feedback lever is in the middle position when the rudder is centered. 6. Troubleshooting
