Controller won't turn on

  1. Check the battery. The Classic uses 2 AA batteries — replace them. The Lift and Elite are rechargeable — charge via the magnetic USB-C cable.

  2. Classic reset: remove the batteries and insert them upside down (reverse polarity), press the power button 3–5 times, flip the batteries back, screw the cover on securely, then try again.

  3. Rechargeable controllers: plug in USB-C and wait at least 15 minutes before retrying — a fully dead controller needs a few minutes to show life.

  4. Inspect the trigger. If it feels stuck or loose, the spring/pin may need the Hand Controller Trigger Kit.

Controller won't connect to the board

  1. Use the right controller for your board:

    • Classic — LIFT4 and earlier

    • Lift — ALL Lift eFoils

    • Elite — All Lift eFoils

  2. Firmware (LIFT5 / LIFTX). The most common setup issue: an Elite or Lift controller shipped with old firmware won't pair. Update it via the Lift app (see Firmware updates).

  3. Power cycle both devices. Turn the board on first, then the controller.

  4. Distance. Stay within ~30 ft / 10 m of the board.

  5. Antenna check (LIFT3 and earlier). Open the hatch: confirm the antenna cable is secure to the eBox, undamaged, and the compartment is completely dry.

Connected but throttle doesn't work

  1. Watch the display while pulling the trigger. If it shows throttle input but the motor doesn't respond, the issue is the eBox or propulsion, not the controller — see Propulsion not responding.

  2. No change on the display? If it is a Lift Hand Controller or Elite Hand Controller, it may need to be calibrated. To calibrate a Lift Hand Controller:

    1. Open the Settings screen.

    2. Press and hold the Settings button for 2 seconds.

    3. Scroll to the Information icon and select it.

    4. Use the arrow button to find Trigger Calibration, then press Select.

    5. At “Trigger Calibration?”, choose Yes.

    6. Follow the prompts:

      • Release the trigger completely, then press Select to set the fully-off position.

      • Pull the trigger fully in, then press Select.

    7. Exit the screen when calibration finishes. The controller should return to normal operation.
