TRANSAS User Guide Version 1
4 Deleting ENC Data
New AVCS customers who had previously subscribed to other ENC services are strongly
recommended to remove (purge) all ENC Permits and ENCs from the system before
installing AVCS. For more information please refer to the pre-installation checks within the
generic AVCS manual.
When there are installed charts in the ECDIS the user can choose to remove (delete)
some or all of the installed ENCs from the system database (SENC).
Chart Assistant: Select appropriate charts → Delete → OK
Note: Do not remove the charts with the AA prefix as they are IHO produced ENC cells
and are used as references by the TRANSAS 4000 ECDIS system. If these cells are
removed a TRANSAS Engineer will be required to re-install these cells.
1. Select charts to be deleted (N.B. Hold Ctrl to highlight multiple cells)
2. Select “Delete”
3. Select “OK”
