If a vessel is not fitted with ECDIS, is ECDIS training still required?

The relevant IMO Circular (STCW. 7/Circ.18, published 22 May 2012) states: “Training and assessment in the use of ECDIS is not required for those who serve exclusively in ships not fitted with ECDIS. These limitations will be reflected in the endorsement issued to the seafarer concerned.”
