The left side of the switch controls the starboard tab. The right side of the switch controls the port tab. To lower the starboard bow, press the right (starboard) side of the switch where it reads Down. This will lower the port tab. To lower the port bow, press the left (port) side of the switch where it reads Down. This will lower the starboard tab. The LED displays on the sides of the display will show how far that tab has moved. When the on/off switch is turned on at the helm the LED displays on the indicator switch will show one up arrow on each side of the switch. This shows that both tabs are fully retracted. While functioning the tabs the LED displays will indicate the position of the tabs by lighting up the further they are pressed Down. As the switch is pressed Up the lights will go out. When power is removed from the switch the tabs will retract from any position before powering down.
