Original warning text

ECDIS SYSTEM.
1. MARINERS ARE ADVISED THAT ECDIS MAY NOT DISPLAY SOME
   ISOLATED SHOAL DEPTHS WHEN OPERATING IN "BASE OR
   STANDARD DISPLAY" MODE. ROUTE PLANNING AND MONITORING
   ALARMS FOR THESE SHOAL DEPTHS MAY NOT ALWAYS BE
   ACTIVATED. TO ENSURE SAFE NAVIGATION AND TO CONFIRM
   THAT A PLANNED ROUTE IS CLEAR OF SUCH DANGERS,
   MARINERS SHOULD VISUALLY INSPECT THE PLANNED ROUTE
   AND ANY DEVIATIONS FROM IT USING ECDIS CONFIGURED TO
   DISPLAY "ALL DATA". THE AUTOMATED VOYAGE PLANNING
   CHECK FUNCTION SHOULD NOT BE SOLELY RELIED UPON. THE
   INTERNATIONAL HYDROGRAPHIC ORGANIZATION (IHO) IS
   LEADING TECHNICAL ACTION TO RESOLVE THIS MATTER.
2. NGA HAS DONE A REVIEW OF DNC AND HAS CONCLUDED
   THAT THIS ERROR DOES NOT EFFECT DNC.
3. CANCEL HYDROLANT 294/10.
