External conditions exceed vessel or JETanchor capability. Point the vessel's bow into the wind before engaging
stationkeeping. Use virtual anchor mode instead. Find
calmer conditions. Increase the idle rpm. Use manual
controls instead.
Vessel parameters have changed since JETanchor was
setup. For example, vessel weight has changed or engine
idle rpm has changed.
Return the vessel to its previous parameters.
