Original warning text

DISPLAY ANOMALIES IN SOME ECDIS.
MARINERS ARE ADVISED THAT THE INTERNATIONAL
HYDROGRAPHIC ORGANIZATION (IHO) CHECK DATA SET
SHOWS THAT SOME ECDIS SYSTEMS FAIL TO DISPLAY
SOME SIGNIFICANT UNDERWATER FEATURES IN THE
STANDARD DISPLAY MODE. THE USE OF THIS CHECK DATA SET,
ISSUED THROUGH ENC SERVICE PROVIDERS AND AVAILABLE
FROM THE IHO WEBSITE WWW.IHO.INT, TO CHECK THE
OPERATION OF ECDIS IS STRONGLY RECOMMENDED. JRC HAS
CONFIRMED THAT CERTAIN VERSIONS OF JRC ECDIS FAIL
TO DISPLAY SOME TYPES OF WRECK AND OBSTRUCTIONS,
INCLUDING STRANDED WRECKS, IN ANY DISPLAY MODE.
WHERE JRC ECDIS IS IN USE, PAPER CHARTS SHOULD BE THE
PRIMARY MEANS OF NAVIGATION UNTIL THE ECDIS HAS
BEEN PROVED TO OPERATE CORRECTLY. SEE
