Section 14 Creating a User Chart/ Updating a Chart Manually  14-2 
 
Manual Update (ECDIS screen only) 
A chart can be updated manually by creating objects (symbols, lines, areas, and texts) on the 
specifying chart. 
In the manually updated chart, objects are linked to the chart itself, unlike user charts. Therefore, 
although the manually updated objects can be hidden, they cannot be deleted easily. 
For the details of hiding objects, refer to "14.4.1 Deleting or hiding an object" and 14.9.1 Deleting or 
hiding an object. 
 
Note 
Depending on the setting of Category (Base / STD / All / Custom), the added object may be 
hidden. 
 
Note 
When SENC SYNC is used, update chart manually at source unit that transmit the chart data.
