Original warning text

ECDIS SYSTEM.
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.
