How to Check Creation and Usage History of
Manual Updates
You may need to check when a manual update has been added into your ECDIS. Also, you may need to check what
was shown in your chart display, for example, what was shown three weeks ago. There are also many other cases
when you need to know what was known by your ECDIS.
To check any situation in the past, you can use either Display Until and Approve Until to specify exact date of
interest. Alternatively, you can specify directly the number of the manual update planning session. See below.
To open the Manual Update Chart viewing dates window, open the Chart menu, select Set Chart viewing dates, then
click the Manual Update Dates button.
