8. Manual Updates 

Manual updates operate like any other S57 chart that contains updates and other set chart viewing dates features. 

When you accept manual updates as permanent, the system sets Display Until of manual updates as current date of 
the system. To set Approve Until as current date of the system, you must open the Set chart viewing dates window 
(in the Chart menu) and perform Approve Until. For how to set current date, see section 7.11 Chart Viewing Dates 
and Seasonal Features of the Vector Chart. Recommended settings in the Chart viewing dates window are: 
•  Sync Manual Update Dates 
•  All SENCs  

See the example below where Display until and Approve until are set as the system current date.
