Automatic retraction The trim tabs will automatically retract: • when the ignition is switched off*, • when the engine(s) are placed in reverse gear**, • when Optimus joystick control or SeaStation are activated (when boat is so equipped). Homing When the trim tab controller is powered on, the system will go through a homing cycle. The trim tabs will retract at slow speed until the end of travel is detected. This ensures the accuracy of the position feedback. During the homing cycle the tab position indicator LEDs will light up sequentially from bottom to top. When the home position is detected the top LED will blink three times.
* Battery switches must remain on. ** Requires a gear position signal. Standard on Optimus systems.
