  If the Keyless Start System does not turn ON even when the main switch is operated and the error sound (five short buzzer beeps) IS heard, consider the following possible solutions: * The key-fob might be outside the operating range. * The key-fob battery could be dead. * The key-fob may be in OFF mode. * The key-fob might not be authenticated. * There could be a communication failure due to strong radio wave or noise. * There may be an electric wiring connection failure between the keyless control unit and outboard motor. * There might be an authentication error between the keyless control unit and outboard motor. * An abnormality may exist in the electronic control system of the engine.

  If the Keyless Start System doesn't turn ON even when the main switch is operated, and you don't hear the error sound (five short buzzer beeps), check the following: * Ensure the emergency stop switch lock plate is in position. * The main switch may have been operated continuously while communication with the keyfob was disabled. * Inspect the battery terminal connection for corrosion or loss. * Verify the battery has power. * There could be a keyless control unit failure. * Check for loose electric wiring connections. * Consider a remote control box failure (Side mount type). * Consider a main panel failure (Top mount type).
